DIY Home Inspection – How to Recognize and Examine the Foundation's Problems
The base walls connect to the top of the soles. The purpose of the foundation is to keep the weight of the house structure from foundation to floor.
Any kind of construction (concrete, brick, concrete blocks, etc.). The base walls are walls due to lateral force, settling, tension or uneven loads (higher weight than a particular section of the foundation). Natural forces such as earthquakes can also contribute to the earthquake regions.
Use cushion and pencil to start checking, while examining the outer base. Make notes of the cracks and their location. If it is in the lower level, try to find them inside. If the crack is completely on the ground, it may be a red flag. Small hair cracks that do not pass through the base wall are common and not worried; it may be due to the shrinkage of concrete or mortar joints.
Cracking detected sometimes causes a similar type of fracture on the opposite wall of the foundation. On similar walls, cracks may have similar causes, except for horizontal cracks caused by lateral forces.
Types of Cracks
Vertical and 45 degree cracks are usually caused by settlements and heating. Horizontal cracking is usually caused by the base side pressure, for example hydrostatic pressure (lateral force). Surface cracks that do not go completely on the wall and there are no signs of shifts are generally not structural errors. Separated vertical cracks that do not extend to the lower edge of the base wall are usually shrinkage cracks. These are caused by shrinkage of the concrete during curing.
Causes of Horizontal Cracks
The foundation should function as a support that resists lateral pressure of the soil on the outside of the tunnel or in sliding locations. If the foundation does not provide enough lateral support, the walls are bent inwards and cause horizontal cracks. Some of the causes of the underlying walls that are too thin or not (or not) are ironing, such as a grid for concrete foundation, before filling the foundation soon enough before the foundation can fully cure or fill it when large stones or hard frozen ground pieces were placed under the foundation.
Causes of Increased Foundations
Cracks based on bricks, blocks or stones (not concrete) are usually cracked by a step-by-step "stair cracking". Stepwise cracking usually follows these materials.
When the concrete is grounded, the cracks of the tension tend to be vertical and wider at the top of the cracking than at the base.
Some areas of the country have extensive soils that increase when water is absorbed, causing cracking. The moisture content of dry, extensive soils, say sudden drops, drastically changes soil volume and in some cases causes severe heating problems and structural damage. When the extensive soil is dried, shrinkage can cause the effect on the base. The method of prevention is to maintain the moisture content of the soil, as the soil is maintained along the soil to the highest possible level. This is achieved by an appropriate classification around the perimeter.
Grounds for the Foundation's Settlement
Ground clearance under the foundation is usually due to cracks in the walls of the wall. Cracks caused by cracks caused by cracks caused by cracks caused by heaving, with the exception of the crack at the wider lower end of the crack.
If the crack is active, the crack may still move (larger and more). To identify the active crack, it will have sharp edges, clear inside the cracks, and sometimes with concrete bits in the concrete. The old cracks will have dust, dirt, paint and insect parts in the crack.
You may need to evaluate a geotechnical engineer to judge the degree of cracking or its severity. The 3/8 "wide cracks must be carefully inspected. The cracks can be measured by the engineer to determine whether it is moving or stable.
Look inside the structure of the house:
The jammed doors and windows that are jammed and not appropriate (slits)
Installing the foundation may result in sliding doors and windows, taking the edges around the windows or doors where they are closed, looking for gaps that are larger on one side than the other, and this can help determine where the Settlement
Cracks on walls
Clearing cracks are wider at one end than the other: let's know that wall coverings are caused by the size and contracture of the house during the seasons If there is no evidence of the Foundation's mistakes, it is more likely that the latter
Sloping or tiltable floors
The home screening chair I learned during the winter that most people will not notice less than 1/8 "sloping feet. The family living in the older home for a long time is not noticeable, even if it is severe. adjust to a gradual slope over time
If there is any doubt, use a level to determine whether the floor level is to be, floor surfaces should be noted for subsequent references during the inspection
Incorrect or intensive conversion without a slope is the most appropriate repair was to stabilize the base.With extensive re-balancing in an older home, interior walls, ceilings, doors, windows and cabinets could cause more damage than expected
If home is stabilized and the future movement unilaterally buyers often accept uneven floors .
