Residential Foundation Repair
Foundation repair is process of lifting a house, to the extent practical, that has moved from its originally constructed design, giving stability to the damaged structure.
There is nothing easy about Foundation Repair for a homeowner. It can be a very stressful process to go through. Our goal is to make this process as easy as possible. We will walk you step by step through the entire process until we have successfully repaired your home.
Concrete Slab Foundation Repair
A slab on grade foundation is a flat concrete structure that most homes less than 50 years old are built on in Texas. Slab foundations are mostly poured directly onto the ground and do not have basements. Most slab foundations will have a grade beam around the perimeter of the slab as well as cross beams running throughout the interior.
Before recommending a repair plan, an experienced foundation repair inspector should consider many variables including: site drainage, age of home, size of home, an elevation survey, and signs of stress.
How do we raise your foundation?
Double Concrete Pressed Pier
Piers are used when a structure has lost elevation beyond allowable industry standards, and is resulting in strain and damage to the structure. The most common pier used is the Concrete Pressed Pier. However, there aren't many companies who use Double Concrete Pressed Piers. Essentially, there are two piers in every hole. The advantage is strength and durability, as well as having a backup if one of the piers were to fail. To install the pier, holes will be dug roughly 2' by 3' to gain access to the grade beam, which supports the foundation. A hydraulic system is used to drive the piers deep into the earth until they reach refusal. Refusal is when the pier cannot be driven any deeper into the earth. This usually occurs around 5000 to 8000 psi. Once all piers are installed, the structure is the leveled and holes are covered. In most cases these piers come with a Lifetime Transferable Warranty.
Pier and Beam Foundation Repair
Pier & Beam Foundations are constructed with treated lumber and elevated atop piers, blocks, or posts. A properly constructed pier & beam foundation will have a crawl space under the house. The beams should be the largest pieces of lumber (usually 4" x 6" under residential houses) and run parallel the length of the house and may be spaced up to 12’ apart. Next, the floor joists run perpendicular, on top of the beams. Joists are generally spaced approximately 18” to 24" apart. On top of the joists sits the subfloor. There will normally be two layers of subfloor which are normally plywood.
This wooden structure is elevated and supported by a concrete perimeter grade beam. Poured concrete piers or pad & blocks run under the beams, spaced 6' apart to support the structure. Repairing a pier & beam home can be much more complex than repairing a slab. There are more moving parts. It is important to replace any rotten wood and make sure there is plenty of ventilation. Proper Drainage is especially important because excess water will rot the foundation overtime. It is vital to choose a foundation repair company experienced in Pier and Beam Foundation Repair.
