Concrete Pier vs. Pier & Beam
Repairing your foundation with concrete piers
Pressed concrete pilings are pre-cast cylinders of concrete, approximately one foot long and six inches in diameter. The installer begins by digging a two-foot hole next to the foundation and uses a hydraulic ram to drive the cylinders, one on top of the other into the soil until significant resistance is felt, strata is reached or bedrock is hit. Concrete cylinders are hydraulically pressed against the bottom of the foundation. This drives the cylinder into the ground against the weight of the house. A concrete cap is then added. Bottle jacks are used to lift the house as close as possible to its original position, additional cylinders and metal shims fill the space between the piling’s cap and the foundation and the house is lowered onto the pilings. The holes are then backfilled.

What the typical concrete pier install looks like
Dig top holes (approximately 3′x3′x3′) underneath the perimeter grade beam of the structure at pre-determined pier placement sites.
Place all loose dirt on plywood or plastic for ease in clean up, and to minimize disturbance of lawn and landscaping.
Use hydraulic power unit to press pre-cast concrete cylinders into ground until jacked refusal has been met (solid strata).
Place cap (trapezoid) block on top of pier cylinders that have been driven to solid strata.
Remove all loose mortar from the cracks in brick veneer.
Using the top of the trapezoid block, size and place a pre-cast concrete cylinder beside a hydraulic jack.
Using a pre-determined sectional approach, raise areas of structure in small increments until structure’s natural position has been attained or .
Using steel shims to secure the lift of the structure, place steel shims on top of cylinder that was placed in Step 8 above.
Remove hydraulic jacks, then size and place another pre-cast concrete cylinder beside the cylinder placed in Step 8, using steel shims to secure cylinders in place.
Place soil in top hole surrounding pier cap. Use a mounding approach to allow for soil subsidence. Remove excess soil from site.
Discard plywood and rake areas free of debris.
Pier and Beam Foundation Repairs
A pier and beam foundation is one of the most common types of foundations in DFW. Older homes are typically built with this type of 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 crawlspace.. The foundation is constructed of wooden beams supported by wooden joists and concrete pad and blocks. DFW Foundation Repair is one of the few foundation companies in the area that works on pier and beam. DFW Foundation Repair has a specialized team that works on pier and beam foundations.
Pier and Beam foundation repair, or sometimes referred to as crawl space foundation repair, is normally required if you have observed one of the usual warnings signs of foundation failure. Have you have observed cracks that have formed above windows, door frames, and wall corners? Are doors in your home hard to close or refusing to close properly? Have interior floors such as hardwood and tile begun to separate or bulge? If you answered yes to any or all of these questions, it’s likely that your pier and beam foundation has failed and is in need of repair. Over time the foundation can settle and shift. Depending on how the foundation is constructed, DFW Foundation Repair will use pad and blocks or piers to stabilize the foundation. Our experienced estimators will do a full assessment and give you an exact cost and repair plan for your home; our estimates are always free.
Repair Process for Pier and Beam Dallas
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. The Pier and Beam Foundation repair is done in several phases. Here is what you can expect from DFW Foundation Repair:
The area is cleared of all shrubs and plants.
The crew is able to enter the crawl space under the structure and replace any rotten wood or broken beams and install piers as needed.
Using hydraulic jacks, the interior floor levels are raised to their natural position. The team moves slowly and systematically to ensure a gentle and uniform lift. The Crew Chief monitors the lift of the structure to ensure the reaction of the structure and interior elevation readings is accurate and does not cause undo strain on the structure.
Once the structure has been lifted to its natural position, concrete cylinders replace the hydraulic jacks to provide permanent support to the structure.
The team corrects any previously installed shimming and replaces it with metal shims, as needed.
Beams are then added, as necessary for the repair of the pier and beam foundation, in areas of the floor system that need reinforcement.
If there is an insufficient amount of interior supports, interior pads and blocks or piers are added to stabilize the interior structure.
Once the excavated area is filled in, any debris resulting from the repair process will be removed.
The foundation is now incredibly secure thanks to the Pier and Beam Reshimming
