Foundation Crack Repair in New Braunfels, TX
We seal slab, brick and drywall cracks with epoxy and polyurethane injection, and we tell you honestly when a crack means the foundation itself is moving.

New Braunfels Foundation Repair HQ has repaired foundation cracks across New Braunfels, Texas for more than 18 years. A crack is usually the first thing a homeowner notices and the hardest thing to read. Some cracks are cosmetic, the ordinary shrinkage of concrete as it cures, and need nothing more than a proper seal. Others are the surface trace of a foundation that is settling, and sealing them without stopping the movement only hides the problem until it returns wider. Our crew does both parts of the job honestly. We inject and seal the cracks that can be sealed, we repoint the brick that can be repointed, and we tell you plainly when the crack you are looking at means the foundation underneath needs support before any sealant will hold.

How Foundation Crack Repair Works on New Braunfels Clay
New Braunfels sits on the Balcones Fault, where Hill Country limestone gives way to the expansive clay of the prairie. That clay swells in wet months and shrinks through drought, and Central Texas cycles between the two hard enough that slabs, stem walls, and brick veneer all crack under the strain. The first task on any crack repair here is diagnosis: we check the crack's width, direction, and history, and we shoot elevations across the slab to see whether the foundation under it is still level. That reading decides which of three repairs the crack actually needs.
Epoxy injection is the structural repair. A two-part epoxy is injected through ports set along the crack, and once cured it is stronger than the surrounding concrete, effectively welding the slab or wall back into one piece. Epoxy is the right choice for a dormant crack, one caused by shrinkage or a past event where the movement has stopped, and it needs a dry crack to bond properly.
Polyurethane injection is the sealing repair. The resin expands into a flexible foam that chases water through every hairline branch of the crack and stays slightly elastic after it cures. That makes it the right choice for a leaking crack, a damp crack epoxy cannot bond to, and a crack that still sees small seasonal movement, because the foam flexes instead of breaking loose.
Repointing and masonry repair handles stair-step cracks in brick. Our crew rakes out the cracked mortar joints, replaces any broken brick, and repoints the wall so the veneer sheds water again. Interior drywall cracks are floated and refinished the same way, but in both cases only after the cause is settled, because cosmetic patches over an active crack reopen by the next season.
The honest part of crack repair is knowing when injection is the wrong answer. If the elevation survey shows the slab has dropped, the crack is a symptom, and the fix is underpinning: steel piers driven to load-bearing soil to stop the settlement, or a full slab leveling and stabilization plan when the movement runs across the main living area. And because so many local cracks trace back to water pooling against the perimeter beam, we often pair sealing with grading and drainage work that keeps the clay moisture steady so the swelling that opened the crack does not simply do it again.

The picture below shows what that work looks like as an illustration.
