Causes of Damage to crawl space foundation

The below-mentioned are common causes of damage to crawl space foundation:

  • Expansive clay soils

Expansive clay soils are the most common cause of foundation problems. Expansive clay is known to expand when it is wet and contract when it is dry. These forces can push around the structure of the home foundation with each season and year. Any push-up from the ground or shrinking and sinking soil can majorly impact the structure of the crawl space foundation.

  • Moisture under the home

A pier and beam home is susceptible to moisture from inadequate ventilation or a poor drainage system. Excessive moisture under the home can damage the wood, from the sill up to the home’s subfloor. Water could cause the wood material forming the crawl space foundation to rot, disintegrate, or mold altogether.

  • Original construction methods or materials

One unique problem with a crawl space foundation is spongy, wavy, or bouncy roller coaster floors. There are pier and beam houses that were constructed with the floor joists too far apart to support the weight effectively. There are also floor joists and shaker sills that are worn out or broken because of extended use. Also, sometimes piers can break down and are required to be replaced.

Methods for repairing crawl space foundation damages

Here listed are some professional methods used by pier and beam foundation repair Dallas Fort Worth:

  • Reshimming

Sometimes, the beams or joists resting on the beams, could come loose or experience some movement. Reshimming involves wedging small pieces of wood and installing them between the piers and beams to fill any gaps.

The pier supporting the home foundation can degrade over time and might need to be rebuilt. Or more piers are required to be added to support and distribute the house’s weight evenly.

  • Replacing beams

Wooden beams and joists resting on beams can become susceptible to dry rot, mold, or wet rot. Foundation repair experts usually detach non-affected beams and replace the rotted ones.
