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.
