How to place a hardcore concrete floor

Hardcore is the underlying material. It is used as a bottom base after the foundation wall has been constructed so that they are lifted before casting the substrates. It is a recommended hard-rock ballast or quarry that can not exceed six inches if the sieve is broken down. This should not include weeds, roots, plant soil, clay, black cotton or other unsuitable materials. Broken stones or brick wings can also be used as hardcore

To place hard beds in floorboards, use good quality, smaller pieces, mixed with fine materials. This will provide a solid mass of mass after consolidation. It should be placed at a maximum thickness of 10 inches. For each layer, sufficient fine material should be added to allow for smooth gradation to achieve a solid mass after rolling. Ten tons of smooth rolling or two-color vibration rolls should be used to compress individual layers.

The eight steps of the roller compact each layer when the hard bed is placed under the floor. Give each hose enough water to maximize compression. Add to each layer a fine layer of sand or quarry powder that was forced into a hardcore by a conical vibrator. All materials used must always be dry to avoid cracking or adhesion. This can allow the pockets of air or free spaces. This can sink when the hardcore weight is loaded. If the sand is absorbed into the holes between the hardcore, it will solidify.

Tightly compress the hard fill under the floor until the sand is absorbed. The top surface should be level. Performing or qualifying levels corresponds to the desired falls. Subsequently, a similar, broken material blinds are added. This is at least in thickness. A ten-ton roller is used to smooth the surface. The hardcore mass is now ready for protection against growing, moisture-proofing and mesh reinforcement before cementing the ground floor.

Foundations – Hazards and Solutions of the House

Home-based foundation is not only unsafe but can also lead to other complications. Concrete can naturally cause cracks on the floor or walls as time passes from the concrete as the pressure extends and shrinks. Some cracks are still big enough to ruin your home from the collapse. If you notice the cracking in your home base, call the trusted foundation company to get the problem area and go time to fix it.

If the flooring of our house is cracking it is important to use a jack system to make sure its floors rise again. The reason is that his floor is cracked because a piece of the floor shakes. This can also damage the outside support of the home because the weight load is now unbalanced. This is a fairly straightforward process by which the floor needs to be adjusted to an adjustable level and to change the transmission system to ensure that the problem occurs over time.

A problem that seems as if something did not show the danger of the basics or walls of tiny cracks. Small refers to how deep the crack and the actual length and width of the crack are. These cracks may leak slowly over time, which may cause mold in the cellar. This mold may degrade stored materials, so this should not be ignored and filled as soon as possible. Small cracks can easily evolve into much larger, dangerous cracks that will inevitably increase to the point where the foundation is unsafe. This is another reason why these cracks must be handled with discovery.

If you notice a big crack in an outer basement or on the floor of the foundation, this may mean that the soil is sinking on the side of the house or under the house. This poses many hazards because the backdrop of the home is the foundation. A solid foundation ensures that the life of the housing is very long. Depending on the situation, there are several clean ways to install anchor systems under the foundation, which ensures that the foundation is completely intact. Or if there is an outer basement wall, an anchor system or other support systems will press the wall so the concrete will not crack

Steel Grills, base technology for supporting structures

Steel Grill is a foundation technique that is often used to support masts, columns, boards, overhead line electrification (OLE) masts and similar structures. Depending on the size and weight of the supported structure, such a conventional type of foundation (sometimes floating primer) is a large box-like structure which is no different from the mesh cages used to reinforce the concrete structures.

is placed on multiple wrenches – typically between four and eight depending on the dependent structure. With this system, construction time has dropped by more than half; with an illuminating column that can be installed in an hour. Quickly install and rely on better technology and innovative design. This technology can be applied to a number of structures that are in high rotation moments and need to be quickly and cost-effectively fitted.

With a specific base, here is a steel grillage (a rigid construction that is well below the ground so that the weight of the soil is equal to the weight of the grillage) replaced.

Structures such as road signs or rail gates are designed to construct one or more steel beams (surface) for the underlying helical piles to provide extra support. The quick installation and the fact that on-site grilling makes this a very versatile, yet versatile foundation solution.

includes –

  • Installation Speed ​​- Using the grillage can often save you valuable time.
  • Convenience – avoiding poured concrete saves time and simplifies installation.
  • Reduced costs – by minimizing disruption to transport infrastructure.
  • Versatility – technology allows a wide range of applications.

Waterproofing Foundation – What are your choices?

If you're going to build a new home, you have to make it waterproof, so in a few years there will not be a wet cellar.

There are various waterproofing products and systems on the market. it may be confusing. So what's your chance?

Here is a brief overview of the most common basic waterproofing systems to help you decide:

1. Liquid Rubber Primer Waterproofing Membranes

Elastomeric polymerised coatings are made of liquid rubber – the tire

Advantages: is dry, cold. You can do it with a sprayer, roller or trowel. The fluid is elastic rubber coated, able to fill the actual small holes and bridge any possible cracks in the walls of the wall. The tire is flexible. They generally take long guarantees and many are environmentally friendly, low-solvent or solvent-free. Very economical

Cons: The possibility of inconsistency of coverage, but the latest products help determine the "right" thickness with the intensity of the color, so if you apply the product, make lighter corrections, just add more fluid. Preparation and hardening of the additional surface may be required. If the structure has larger cracks or holes, it must be filled with cement or other finishing material before applying the entire coating. Some of the liquid membranes also require longer curing time of the concrete before it can be applied to ensure proper bonding

. Hot Applied Liquid Rubber Primer Waterproofing Product:

Rubberized asphalt compound that forms a strong, flexible monolithic waterproofing membrane. Can be applied to the roof

Benefits: Experience almost any structural surface. Ideal for uneven, uneven surfaces. Monolithic, seamless, watertight, eliminates water migration and moisture accumulation. Provides strong protection due to its application.

Cons: The surface should first be primed. Costs are higher because the product has to be applied in layers – basically the first warm-coated rubber to be applied, the fabric-reinforced sheet must be pressed quickly into the hot layer and a second layer of hot liquid rubber is waterproofed. Depending on the local building code, 2 or 3 of these sheet layers may be required. That's why flexibility is low. And since Hot is, it must be very careful – it is best to use a certified technician.

Advantages: Advantages: The largest one is of a uniform thickness because it is "prefetched" to the desired standard . Mechanically strong, resistant to hydrostatic pressure. Cover larger holes or damaged areas

Can be used for Concrete, Metal, Wood or Masonry

Cons: Very "sticky" makes it harder to apply the on-site costs higher. The application must load at least 2 people.

It requires a lot of extra work = extra cost. If there are any irregularities on the surface that you want to place on a sheet, you must first smooth a layer to smooth the surface. You need to learn about articular joints, joints, corners, intrusion, foundation, patch, etc. And once the piece falls, it will not return it again in usable state. Cemented waterproofing

Cement-based flexible waterproofing membrane. Portland cement, sand acrylic blend, plasticizer and other active waterproofing chemicals to increase its durability and efficiency.

Advantages: Very easy to use, just mix the powder with water as recommended by the manufacturer and apply with a brush or trowel. Very accessible – available from suppliers of masonry products or from specialized traders. Paintable. Also available in different colors. In most cases, one layer is sufficient, although some areas may require the use of a reinforcing mesh. Low cost. Corrosion and weather-resistant. Can be used as a positive or negative lateral waterproofing

Cons: No flexibility – cement does not stretch back, so the structure will diminish the potential of future cracks. Before applying the surface, there are no protuberances, expansion cracks, oils, paints, water repellents, and any other foreign matter that may function as a breaker. The holes should be filled with an approved block filler

. Bentonite Waterproofing

is a water-insulating primer under bentonite clay, consisting of sodium bentonite clay consisting of two layers of woven and non-woven polypropylene fabric. Like clay panels and boards.

Benefits: You can absorb a huge amount of water. And as the water swells in the clay, it moves itself into cracks and hollows, where it constantly blocks the water. It is flexible and resistant to most chemicals. Not toxic, not polluting. No smoke. Can be applied in cold weather

Cons: Due to the clay function, the seal does not develop until the priming is loaded and the water reaches the bentonite material, which means it can not confirm integrity. Seal


As you see a lot of things, your own situation, needs, requirements, and depend on what you feel. The best way to talk to experts is to check the manufacturer's requirements, especially for concrete mixing time, temperature restrictions, and further labor requirements. Yes, the waterproofing of the primer may seem priceless, but remember that this is a long-term solution that will save you a lot of time, headaches and money in the future. to spare it.

Foundation Wall Cover Repair – Vertical Cracks

Vertical cracks in the foundation are most commonly caused by shrinkage and cure of weak building practice or foundation concrete. These cracks are common in both newly built homes and older ones. While vertical wall cracks in the foundation often do not cause structural problems, often as often as horizontal cracks, they often leak water from the primer to the basement or crawl space. In fact, this flow of water can be so difficult for some customers to say that the water literally smacked into the house!

The unfortunate truth is that no one wants to buy a home with a leaking groundwall crack. Of course, no one wants to live in the home with the basic water! Damaged or deteriorating walls give rise to major problems for homeowners and their bank accounts. The ground ground water entering the basement makes it difficult (if not impossible) to home and loses 10% or more of its home. This means that for a $ 200,000 home the value will be $ 20,000! The problem only worsens over time as more and more water flows through the crack, and natural forces make the crack even wider.

Solving the drill bits is not the answer. In many cases, homeowners try to fix the problem by simply adding the gaps. The sealing gasket creates a flow of water as the water fills the cracks in the filling and draws this plug. In addition, if the crack is not clear then the hose is bound to the dirt instead of the cement, which weakens the efficiency. Of course, the seal will work for a while, but if you want to solve the problem so that the floor will never leak, then that is not the answer.

Cracking walls with hydraulic cement or other rigid materials is also a failure. The problem here is that while the hole is plugged in, there is a problem (the base water externally pressed) still exists. Over time, when the foundation swells and shrinks against changes in temperature and moisture, the movement loosens the connector. Leakage of the foundation often begins again two years later.

With the use of epoxy, the seal can still be retained, but because of its stiffness, the wall simply ruptures nearby as it is further expanded and contracted. In addition, the epoxide is very slowly healed and is actually leaking from the other side of the crack before it is fully cured. The surface to which the epoxide is added must be completely dry to form an appropriate bond. Alternatively, urethane seals work better because they are flexible and expandable, but cracks can easily be shifted and expanded by more than 100% over time, far beyond the extensibility of the material. Dirty Work ]

Another possible way to crack the leaking base wall is from the outside. To do this, you need to subtract the foundation and uncover the whole wall. Hopefully there is no pavement, bush, garden, first stairs or anything else in the area where the crack is located or removed. If you have a porch, deck or stairs, you must work or remove some way. The leakage of the dirt leaves in the yard and becomes irregular and will become increasingly porous and water-repellent by reflection of the dirt. While multiple layers of synthetic waterproof materials installed often effectively solve the problem, if the stamp fails, the whole process must be repeated. In addition, the ground discovered during the coming year will need to be recovered in order to prevent concentration around the funds and the problem.

Basic conditions for waterproofing

Absolutely necessary water resistance to your home. Basis waterproofing is a critical step in maintaining home value and is an important measure to prevent very serious damage. Generally, the professionals carried out by foundation waterproofing are generally not recommended as a do-it-yourself project. Your home is probably the biggest investment and the waterproofing of the foundation is essential to protect the investment. Ideally, basic waterproofing is done by building the house, but due to settling years and water leakage or neglect, entrepreneurs often leave their homes unprotected.

A short-term waterproofing method is the black tar for waterproofing the primer, but this is certainly not recommended. Keep in mind that this is a very short-term method that is dry, cracked and let the water turn back within five to eight years. From a technical point of view, tar is a moisture-proofing method, not a waterproofing method. If you decide to try self-priming waterproofing, we recommend using a rubberized fluid membrane, which is basically the same as car tires. The liquid membrane is quick to dry, cheap and generally easy to apply. Can be used with a roller, sprayer or trowel. Keep in mind that this method has the potential to prevent the membrane from being applied. Be sure to use it properly. Again, the basic waterproofing is usually reserved for professionals. There are materials and methods for those who want to do this, but it is a good idea to first research, as it is important to do the right job.

Costs for repairing a house foundation

When thinking of a home struggling with a foundation problem, we think how much trouble the repair can cause. In the case of the first sign of damage, contact an entrepreneur night with the cost estimation and repair cost.

How do you get an estimate?

Entrepreneurs take many factors into account when estimating the improvement of the foundation. After the initial check has been performed, it measures the damage and determines how long the foundation will be fixed. In addition to the cost of labor, estimates are also dependent on the type of material to be used and the causes of the damage.

Before committing to an entrepreneur, you need to get at least three estimates to compare costs. However, it should not automatically go for the cheapest estimate. The type of materials used and the reputation of the contractor must be taken into account. Sometimes it's worth it to pay more for a better job. Do not forget that you will pay more if you change your job due to lower jobs. Another factor that defines the costs is the area where the damage is. Some areas of the foundation will be more likely to be repaired than others.

When people fix their basics, they usually choose other home fixes. These services often include pest control, earthquake-proofing and seismic anchor bolts. These services will pay more money; however, it allows you to perform all the necessary services at a time rather than at different times.

Improving the foundation will pay you a lot of money. Most people require payment plans and / or loans for this problem, though it is a good idea to see if the homeowner's insurance cover covers the costs.

Old Home Foundation Repair

In the era of houses, time-consuming repairs and maintenance are required. One of the most important parts is an old house where special attention must be paid to the basics. If damage occurs in this part of the house, it can become very expensive repair work

Possible causes:

As a time of houses, they also create materials. They will be weaker with age, which will cause damage. These damages can be caused by several factors that can be aggravated by the age of the house. Regular maintenance in this part of the house is essential to rescue the worsening of the foundation's repair.

Another factor causing damage to your home is water damage. If there is any leakage from the pipes or sewers, you can damage the basics. Unfortunately, water damage is sometimes difficult to detect until it is no longer too late. As soon as there is a suspicion of causing any damage to the foundation, the first step is to take pipes and sewer pipes from a professional plumber. This will help the offered entrepreneurs to improve the foundation and find the home improvement method.


The cost of restoring basic damage can be very expensive depending on the magnitude of the damage and the size of the home. A typical house can cost up to $ 30,000 with moderate damage. Costs include labor costs, the first visit by the contractor and the materials used during the repair.

Although the cost of repair is very high, it is a cost that can not be abandoned. If you ignore structural damage to the foundation, you only ask for a catastrophe. The cost of rebuilding the house significantly exceeds the existing improvement.

HUD Requirements for manufactured home based

Want to buy a produced "mobile" home and finance it with an FHA loan? Would you like to refinance your current credit with an FHA loan? If so, an authorized structural engineer must investigate the foundation of his home in order to comply with the HUD manual 4930.3, the "Standing Foundations Guide to Manufactured Houses" and the House and the 2008 Economic Recovery Act (Entered into force on 30 July 2008). New homes must comply with the requirements of the HUD manual 4145.1, REV-2, CHG-1 "Architectural processing and home mortgage checks" and are reported on the HUD-92051 "Compliance Check Report"

. the requirements written by HUD are often stricter than local building codes. The purpose of these requirements is to make your home safe while increasing your ability to withstand strong wind and earthquake, withstand moisture problems and increased bearing strength to reduce the possibility of accounting for foundation.

The following is a list of basic HUD basic requirements:

• Concrete flooring or approved artificial foundation should support piers.

• When using Concrete Blocks (CMUs) as piers, the piers or Portland cement mortar should be placed or piled dry and coated with fiber-reinforced, surface-bonded cement. Steel stands are approved bait substitutes, provided they are designed and closed by an authorized engineer.

• The chassis must be secured to the support (screwed grounding pins are not allowed).

• Hold the base with a durable base. From May 21, 2009 vinyl or metal plinth materials are allowed.

• Provide adequate ventilation in the crawl space. 1 square meter net free space occupies 150 square meters of crawl space at the edge of the home.

• The ground under the house must be covered with a minimum 6 mm polyethylene vapor aperture.

• All equipment used to transport homes (languages, axles and wheels) must be removed from the scene.

• All utilities must be permanently installed

As you can see, the requirements are more stringent than most construction codes. I recommend contacting locally licensed architects who can assist you in determining the adequacy of your home and what steps you need to get your home grounded.

Can I sell my home foundation's problems?

If your home experiences the foundation's accounting, you can ask yourself, "Can I sell my home?" The short answer is almost always "no". There are a number of reasons:

  1. We all know that home buyers are looking for homes, features, location, good prices, and so on. But it is important to note that structural problems are easily scared. Any material problem will almost always hurt them.
  2. Homeowners generally ask a building supervisor to investigate the prospective purchase. These trained professionals will almost certainly find anything that is bad or potentially bad at home. Reporting can easily frighten your client.
  3. If your home is funded, the financial institution often hires a building supervisor to protect your interest in a property. They do not accept material issues such as weak and groundbreaking bases, basement walls, or similar structural difficulties. The loan will be reduced.
  4. If you are aware of a structural issue, many states are obliging the seller to disclose such information. Failure to do so will render the seller liable and can be successfully prosecuted for false presentation.
  5. The current real estate market is clearly a buyer market. There are fewer buyers than selling houses. Therefore, the receiver may be highly selective. There will probably be another house on the road that is equal or better, and perhaps for less money. Structural issues push potential buyers back to the front door.

Although short answer is not, there is still hope for foundation problems. If you find money with someone or you are willing to enter into a land contract you will be home to the problem. But you must accept a significantly reduced price, even because of today's low prices. But the seller has to decide how much he wants to sell.

But if you know you have a problem, and you deal with it then you can sell the customer and the auditor with complete confidence and complete revelation and you know that the structure fits in a stable, strong, and long-lasting way. You probably will probably sell it to cover your repair costs and much more.

The key is to get an authorized, trained, certified and experienced trader to repair a suitable steel spiral pier or push pier. Steel piers serve as a basis for the problem. Without doing anything, it's just a knitting. Steel piers are accepted and determined by engineers and building inspectors. The foundation repair jets will return their value and allow you to sell your home.
