Concrete cylinders aligned flush, driven by a hydraulic press, and capped with a concrete rectangular block. This allows for a jack and a cylinder to shim off following the lift of the foundation. This option is not only economical but provides long term stability in the right soil conditions. These are the most commonly seen pier systems in foundation repair in Texas, and are the easiest to install.
The cons with this foundation repair method is that they are not effective in highly dense clay. The greater surface area of the six-diameter piling quickly builds up friction in the dense clay, and does not penetrate the active stratum. This can lead to repeated warranty visits and cosmetic repairs, and can lead to frustrated homeowners. The weight of the existing structure is required to install the pier system, and minor stress to the foundation can occur during this process.
Consists of interlocking twelve-inch segments of steel pipe with a friction reduction plate allowing for maximum depth. Steel piers have lowest fail rate of any system, and can average five times more depth than a concrete pressed piling system. This foundation repair system also offers the highest safety factor, meaning that can support more load than the other pier systems on the market. Once the steel pier is pressed, the pipe is filled with cement to prevent migratory water build-up. This prevents the possibility of upheaval, and reinforces the overall strength of the pier.
The cons with this foundation repair method is the inflated material cost, and the additional preparation time to install. The weight of the existing structure is required to install the pier system, and minor stress to the foundation can occur during this process.
We are specialized in pier and beam foundation repair, and all of the various services that go with it. We are also experienced with historical post and beam foundations, block and base foundations, and modern pier and beam foundations.
Our foundation repair services include wood replacement, pad and block systems, poured in place piers, and shimming existing piers.
Our lumber replacement includes floor joist, doubled to quadrupled beams, sill plate, sole plate, and sub flooring. We only use high quality pressure treated materials, and the sub floor material comprises high quality plywood.
Pad and block supports are recommended for foundation repair on lightweight pier and beam homes that have positive drainage. This consists of sixteen by sixteen inch concrete pads, and concrete blocks are stacked up to support the beams.
Poured in place piers are recommended for foundation repair on heavier pier and beam homes, and homes with negative drainage. These are dug below grade, and at are least twelve inches thick, and steel reinforced.
Drilled ten to twelve foot deep pier with a twelve-inch diameter auger, reinforced with rebar, and filled with a five sack concrete mix. The preferred method when working with lightweight structures. Highly dense clay soils due to its ability to reach suitable depth in comparison with other methods. This is an ideal solution where depth will either surpass, or equate to that of a steel or a concrete piling. Drilled piers are also ideal foundation repair solutions for lightweight structures where the use of a hydraulic press for installation can cause damage. Pier and beam homes are often times suitable applications for drilled piers as well.
The cons to this foundation repair method is the limited amount of depth that can reached. A limited access rig or skid steer is effective in reaching a depth of ten to twelve feet, but both are limited beyond this. In areas where the other pier systems average more depth, we will typically recommend another system over a drilled pier. The concrete is also required to cure for a minimum of five to seven days, so the overall process takes longer to complete.
A steel shaft with round helix plates that allow the pier to screw into the ground. The helical piers are drilled into the soil until they reach enough kips, or measurements in force, to support the structure. This foundation repair method is ideal for tying back bowed walls, lifting light structures, and working with sandy soils. With helical piers you can expect minimal ground disturbance, quick installation with open access, and minimal vibration to existing structure. Some engineers prefer this system in foundation repair due to measurable torque that is applied to the pier. There is also limited stress that is applied to the structure being repaired, which is an advantage to older foundations.
The cons to this foundation repair method include accessibility of the installation equipment, cost of material, and active clay soil in North Texas. This system is seldom offered due to its limitations in the Dallas- Fort Worth area, but it does have utility in some applications.
A three-foot by three foot square haunch dug out below the existing structure that is filled with concrete, and reinforced with rebar. This is ideal for retaining walls, wing walls, areas with shallow rock, enclosed patios, or anything lacking a grade beam.
The cons to this system is that it requires five to seven days of cure time, and has limited uses in foundation repair. Long term stability can be affected if there is negative drainage, or the bottom of the footing is still in the active clay.
The combination of a double walled steel and high-strength concrete to provide maximum shear strength and compression resistance. More depth is achieved in comparison to a concrete pressed piling, or drilled pier.
Each segment is pressed into the ground until it reaches bedrock, or very dense strata. Interlocking segment by segment, this pier ensure a strong monolithic pier, resulting in a sound structural integrity.
The cons with this foundation repair method is that it does not always reach the same depth as a steel pier. The weight of the structure is used to drive the system, and minor stress to the foundation can occur during this process.
A mixture of screened topsoil, and cement injected beneath the slab through a 2″ drilled hole. The drill holes are placed on the thickness of the slab and the amount of existing void. This is an ideal method for non post tension slabs lacking adequate internal grade beams, floating slab foundations, driveways, roads, and pools. Long term success of this method is dependent on non compromised plumbing and drainage around the pertinent structure, and has a limited warranty.
The cons to this foundation repair method is that the cured mixture is on top of the active clay soil. This means that if the clay soil expands or contracts following the repairs, the structure will still move. Broken plumbing lines are filled if they are not identified prior to the foundation repair.
We install surface drains with low profile catch basins to trap incoming surface water, and deep french drains to remove subsurface water. Both systems will mitigate potential upheaval issues in the right application. The need for foundation repair can be mitigated in some cases with simple drainage correction.
Our surface drain consists of twelve inch by twelve inch low-profile catch basins, and are all tied into a solid four-inch PVC line. Basins are spaced every eight feet, and the grading is sloped around each basin to direct the surface water into the surface drain. Gutter down spouts can also be tied into the drain, and exited through the city curb, or a pop-up valve. This drainage solution is a great way to keep a pier and beam foundation dry, and can prevent the need for foundation repair.
A three-foot wide tunnel is excavated under the foundation to expose existing beams for installation of new pier systems. Tunneling is recommended in foundation repair to prevent damage to post tension cables when internal piers are required. This will also prevent the client from having furniture relocated, as well as to preserve wood or tile flooring.
The primary con with tunneling for foundation repair is the overall cost. This is a very labor intensive process, and tunneling cost adds up very quickly at two-hundred dollars per linear foot. The cost of repairing expensive flooring, or protecting furniture often times will justify the spend.
