Most modern homes in Texas have slab foundations but even slabs come in different types. A slab foundation is just what it sounds like - a solid slab of concrete poured directly onto the ground. The good news is that its simplicity is its strength, the catch is that it doesn’t usually feature crawl spaces to allow access so that homeowners can get in and check that their foundations are still holding up as they should. Identifying damages to slabs, usually meaning cracks caused by subsidence of some kind is best left to the experts, so if you want to be sure your slab is a solid as a rock and not in need of help you should call Humble Foundation Repair for your free inspection.
Signs to Look For
It’s possible for an entire slab to shift but it’s more likely that subsidence will lead to uneven pressures on the slab and lead to cracking. That in turn causes localized areas of height difference and the first signs that your foundation is taking the strain can be easy to miss. If doors that once fitted now start to stick, if any walls look slightly bowed, or cracks appear in tiles then individually that could just be the walls or floors concerned but together they suggest that the slab is no longer structurally sound and needs reinforcing and repair.
There are different ways of repairing a foundation slab ranging from jacking and shimming through mudjacking and piles and the way to decide which one is by a thorough analysis of the soil type under your home. Different layers of sand and clay will help us determine which is best: even the choice of piling will depend on the soil type since pressed concrete piles can find ‘false’ floors if they encounter layers of clay where steel piles will pierce through and give a more solid grip. Let the experts at Humble Foundation Repair talk you through the best way to save your structure and protect it long term.
Mudjacking, or slab jacking is a process whereby we drill holes through the concrete slab and pump slurry under it which settles and lifts the slab. It takes skill and experience to get it right so that the slab becomes level afterwards. It only works in certain situations and you need the experts from Humble Foundation Repair to ensure that mudjacking is the answer to your slipping slab.
Grade Beams and Pilings
One of the ways we judge the quality of building foundations is by the use of grade beams with slabs. A grade beam is a load bearing concrete beam typically following the perimeter of the property and while a slab foundation can be built without a grade beam many architects and construction companies prefer to include them. Some go a step further and include multiple grade beams in a checkerboard pattern under the slab. The importance for us is that grade beams provide a strong point that we can then use to put concrete pressed pilings or steel piles into place so that the foundations reach deep into the soil and the grade beams sit on top of them. When the experts from Humble Foundation Repair inspect a slab foundation and pier beam we look to see if we can exploit grade beams to give your foundations a much deeper and more solid grip into the ground to ensure that your foundation problems never come back.
