REASON ONE: The picture above is intended to illustrate the construction of the foundation before the cement is poured into place. The typical slab foundation is made up of perimeter boards that make up the actual layout of the slab. Within this perimeter there are beams dug around the perimeter and interior of the slab, these beams vary in size but are usually no deeper than 24 to 30 inches deep. The beams are what actually support the weight of the structure. The deeper the beam the less likely it is for future settlement. Some slabs will have concrete drilled piers spaced 8 to 10 feet apart, the depth of the pier is typically 10 to 25 feet deep. A slab foundation constructed on piers have a deeper footing and is less likely to settle in future years. If you are considering building a new home we recommend that you insist that the foundation be constructed on piers.
REASON TWO: The soil in the metroplex consists of a high content of clay. The clay expands when it is wet and shrinks when it is dry. Tests have shown that the clay soil will expand and shrink as much as 4 to 5 inches. The effect this has on the slab will over time cause settlement. Some houses never settle while others do. The difference is the depth of the beams or whether the structure was built with piers to start with. This is why it is important for there to be proper drainage around the perimeter of the slab. Too much water around the foundation will cause the slab to heave and then when the soil becomes dry and shrinks the slab settles. This movement will cause brick veneer cracks on the exterior and interior sheetrock damage.
REASON THREE: Large trees that are too close to the slab will make the soil shrink at a more rapid rate than the area where the trees are not located.The roots of the tree use the water in the soil and causes shrinkage. This contributes to settlement and foundation deflection. If large trees are growing too close to the foundation we recommend root barriers to better manage theirgrowth patterns.
Reason Four : Plumbing leaks can go undetected under a slab foundation. The leak can cause the soil to swell and the slab the heave. We recommend a plumber test the water lines before and after foundation repairs.
In summary, you are less likely to need the service of a foundation repair company if:
1. Piers are installed when the house is constructed.
2. Proper drainage around the perimeter of the foundation. Water should drain away form the structure, not towards it.
3. Trees should not be allowed to grow too close to the house and if they are, then root barriers should be installed.
