Repairing Your Leaking Foundation

Whenever your foundation lets water leak in, that's a problem. It is a mess to clean up and creates unhealthy indoor air quality and contributes to foul orders, mold, and other humidity-related infestations like wood rot. If the leaks occur at least once, it's likely to return until its fixed.

leaking basement wallsSigns of a leaking foundation include dampness, lingering humidity, sheens on concrete surfaces, window condensation or mildew gathering in a cold corner. Cracked, buckling or bowing foundation walls can allow water in, as can sagging or buckling floors or damaged plumbing. Leaky egress windows or a faulty or damaged basement sump pump can also cause leaks in foundations.

Repairs for a leaking foundation can range from structural foundation repairs like wall anchors or braces for walls or piers for floors, to basement waterproofing solutions like advanced drainage systems, sealants, vapor barriers and pumps. First, a trained expert should identify the source of the water with modern moisture detection tools. If water is leaking in through the floor, there may be footing drains that need to cleared out or a curtain drain - a french drain that is a shallow trench -- might fix the problem.

Frequently Asked Questions

  • A foundation repair project generally takes less than a day to complete with the proper
    assessment, trained experts and the right equipment. For repairs that require some yard
    disturbance - wall anchors or pier solutions -- a small surrounding area must be excavated,
    although disturbance is kept to a minimum, allowing for working in tight areas. The more
    widespread foundation problems are, the larger the repair system required, taking extra time.
    Once the project is completed, all signs of work will be covered as dirt is put back into place and
    landscaping restored.

  • Drywall cracks, if not caused by seasonal changes in humidity, may also be caused by structural
    problems. For example, poor settlement leading to cracks in concrete slabs often indicates that
    sagging walls are next and drywall is soon to follow. If your house is built on uneven soil, the
    shifting and sinking will result in cracks forming on your interior walls.

  • Thrasher guarantees customer satisfaction, offering a transferable warranty. Foundation repairs, basement waterproofing and crawl space repair are backed by 25-year warranties, while concrete repairs have a 5-year warranty and egress windows have a 10-year warranty. When any owner sells the home where Thrasher has performed the work, the warranty transfers to any new owners, through the life of the warranty.

  • Wall anchors are a very common solution in foundation repair, particularly for issues like bowing walls caused by lateral pressure from soil expansion. There's little excavation work, with an anchor plate placed in the yard and another on the basement wall, joined by a steel rod drilled from the inside anchor to connect them. The inside anchor plate is topped with an adjustment nut that helps pull your wall straight, reducing instability in your foundation settlement and wall bowing.

  • A push pier is a series of sectioned, hollow steel pipes, which can fit together into a longer shaft. A small area outside the foundation is usually excavated to get access to underneath the foundation. In the process of installation, the sections of pipe are driven down through unstable dirt until it can be firmly footed in load-bearing soil. They are then attached underneath the foundation with a steel bracket to address settlement by shifting weight on to the pier, lifting and stabilizing a sinking foundation.

  • Many minor cracks are simply visual, and not indicative of serious structural damage. However, to distinguish this from cracks that might indicate more serious problems, look at the size and number of cracks. If cracks are more than 1/8 inch wide, span a large surface area ,that's probably serious. If the cracks are growing over time or allow moisture and gases into your basement, it signals the foundation is starting to give way under pressure and is losing its integrity, becoming more serious.
