Foundation Repair in San Antonio

Bexar County is made up of sandy loam soils and clay soils, both of which affect your home’s foundation differently. Sandy loam soils put your home at risk during the rainy season in San Antonio – usually during May, June, and October. During this period, sandy loam soils are affected by soil washout in which the ground becomes too muddy and eroded to properly support your foundation. Meanwhile, clay soils in the area expand in size as they absorb water and push against your foundation. In both cases, problem signs arise around your home such as floor and wall gaps, settlement and sinking, or drywall cracks. FSS has solutions designed to permanently protect against this type of damage. We use pier systems, wall anchors, and support jacks to keep your foundation safe.

Crawl Space Waterproofing & Repair in San Antonio

Even though San Antonio is dry for most of the year, the rainy season brings higher humidity along with it. This puts any homes built on a crawl space foundation at risk for damage. When humidity gets into your crawl space, it can lead to many problem signs including wood rot, mold, or a sagging floor. Once these problem signs occur in your home, they will only get worse over time without the proper crawl space solutions. Thankfully, FSS offers thorough crawl space encapsulation that will keep all moisture out of your crawl space. This includes the use of vapor barriers, dehumidifiers, and vent covers.

Concrete Lifting in San Antonio

Homeowners use concrete structures nearly every day – from the driveway to the sidewalk outside their home. Concrete in San Antonio is affected by wet weather the same way as your foundation. However, dry weather also causes damage to concrete. During the driest months of the year, clay soils throughout Bexar County will shrink in size and become brittle. In this stage, the soil cannot properly support concrete on your property. As a result, the concrete crushes through the weak soil and sinks into the ground. This leads to uneven driveways, cracked concrete, or unlevel steps in your yard. FSS uses PolyRenewal™, a leading polyurethane injection system that protects concrete from the elements and levels it back into its original position for good.

Find Your Service Area


As a homeowner in Texas, you’re probably wondering if exterior waterproofing is even necessary. After all, Austin and San Antonio receive below average amounts of rainfall every year. However, the wettest months in Southeast Texas are May, June, and October. When the rain does come, it causes problems in your soil, and collects in your yard. If your home is unprotected during a particularly heavy storm, it can lead to tons of problem signs and damage on your property. Its best to stay protected with exterior waterproofing, because you’ll save money and avoid repairs in the long run. 

Installing wall anchors is a specialized task that deals with critical structural elements. If you don’t know what you are doing, you could end up causing more damage than you fix. As such, you should never try to repair your own foundation. When you hire expert technicians from FSS, you can count on a solid installation and a lasting reinforced structure for as long as you live in your home.

Wall anchors are one of the most affordable ways to repair a bowed, cracked, or leaning foundation wall. They are much less expensive than a complete wall rebuild, and they prevent costly damage from occurring to other parts of your home.
