What exactly is Foundation Repair? Foundation repair is the action of stabilizing a house or building that has moved from its originally constructed design giving stability to the damaged structure.

Perma-Pier Foundation Repair of Texas understands "one size fits all" can't work when it comes to foundation repair. Our evaluators are trained and educated by our staff Master Geologist giving them the best tools and technology to formulate the correct solution for a long lasting, quality repair.


Slab Foundation

A slab foundation is the foundation of a structure built directly on soil with no basement or crawl space, normally built of concrete.

Using concrete piers to level a house or structure involves the use of strategically placed mechanical jacks to lift the settled house or structure to the proper height. This must be done carefully and professionally to avoid further or unnecessary damage that can be created if not repaired by experts.

Pier & Beam Foundation

A pier & beam foundation is the foundation of a house raised off of the ground using beams, joists, understructure supports and often a grade beam with a crawl space allowing access to plumbing and wiring. Older homes build prior to World War II were usually built using a pier & beam foundation

Repairing a pier and beam foundation is very different from a repair on a slab foundation. It is important to choose a qualified company to make this repair. At Perma-Pier we use concrete or steel piers to lift your home's structure. Both types of piers are excellent for structural foundation repairs on settling foundations that are caused by organic soils, shrinking/swelling clays, soil erosion, and soil compaction. This method will support and stabilize the structure's load bearing walls, transferring the weight of the structure from the least resistant soil onto the piers that are installed deep into the ground.

Our teams of specialized evaluators and construction staff have many years of training with the highest quality of materials for "vintage homes" and pier and beam foundations.


Whether your home is on a sewer or septic system, the systems within your home are essentially the same. Drainage systems do not depend on pressure; wastewater leaves your house because the drainage pipes all pitch, or angle, downward. Gravity pulls the wastewater along. The sewer line continues this downward flow to a sewage treatment facility or septic tank.

With drainage issues hanging the grade when possible is the preferred solution. Most structural engineers would agree that the soil adjacent your foundation should be low enough to show 2" to 4" of foundation concrete below the bottom brick line. The soil should slope away from the house at a rate of at least ½" per foot. This would prevent water from ponding near the foundation. If site conditions do not allow this change in the grade, then a surface drainage system consisting of catch basins attached to solid pipe can be installed.

What is underpinning?

Underpinning is a method used to increase the depth of a foundation or repair a damaged foundation . A visible sign that your building needs underpinning are cracks in the foundation, interior or exterior walls, sticking windows or doors. When a house or building needs foundation repair, some cracks, especially those wider than ¼ inch appear visible and underpinning is one method of repairing or securing a foundation.

Free Board Over Lift

Free board over lift is a much more complex process of installing internal and external piers under the entire foundation of a house or building. This process involves creating a break out or tunneling beneath the foundation to install a plan of repair.

For homes with extreme movement and major foundation damages a Full-Free Board Lift is recommended. Working with a licensed engineer's specifications Perma-Pier will place piers at specific intervals under the foundation and slowly lift, with professional mechanical jacks, the complete foundation until the soil is no longer able to come into contact with the foundation. Although this method can appear extreme it will eliminate any need in the future for further repairs of the foundation. This is a good method for highly unstable clay soils as we sometimes see in Texas.


Pressure grouting is a process of injecting a Portland cement and sandy loam mixture through a 2-inch hole under the slab to lift the foundation.

Pressure grouting, also known as Mud-Jacking, can be used on most types of slab foundations, roads, pools, sidewalks, and can be less invasive than interior piers since the application is being applied through a small hole and is an effective solution to fill voids lifting the foundation.

Before and after retaining wall images

A retaining wall is a stabilizing structure used to hold sloping ground in place and to prevent the erosion and the movement of soil.

Retaining walls need to be substantial and sturdy enough to accommodate and redistribute pressure caused by sloping ground and drainage. It is normally designed with seepage holes, which allow collected ground water to escape. This releases the additional pressure created by accumulated water and helps keep the wall stable.

At Perma-Pier we use several different materials to construct a retaining wall. Stone and concrete are a commonly used materials, as well as special blocks crafted from aggregate materials and light concrete that are designed specifically for this purpose. Some styles interlock, making assembly simpler, less costly with less construction time. Because each block fits securely with the next, they do not require mortar to hold the blocks together.

A retaining wall can be a series of "steps" or tiers, which can allow a more attractive design as well as more efficient erosion control.

Aside from the aesthetic value of a tiered design it can also provide better erosion control by breaking down the amount of soil, and therefore pressure, held by each division of the wall.
