Water Control
Stop water intrusion at the wall face, not after it has already soaked through the concrete.
What Goes Wrong
Each failure mode below has a specific layer in the assembly that addresses it, skipping any one layer shifts the load onto the others.
Applying a cementitious coating inside the wall traps hydrostatic pressure rather than relieving it, and the coating eventually cracks under load.
A bentonite or liquid-applied membrane on the exterior wall face intercepts water before it contacts the concrete surface.
Without a drainage board over the membrane, water pools against the wall and builds hydrostatic pressure that no membrane alone can resist indefinitely.
A drainage board channels water downward to a perimeter drain at the footing, keeping pressure off the membrane surface.
Cracks and construction joints are the most common entry points; leaving them untreated means water bypasses even a well-installed exterior membrane.
Polyurethane crack injection and a weep system at wall-to-footing joints seal active entry points while allowing controlled drainage.
Dallas expansive clay swells when wet and shrinks in drought, creating cyclical lateral pressure that shifts the membrane and opens new cracks over time.
The membrane type and drainage capacity are selected after reviewing groundwater level, soil conditions, and backfill depth specific to the site.
Scope of Work
Each layer below addresses a distinct point in the water’s path from the soil to the interior wall face.
Bentonite sheet or liquid-applied membrane bonded to the exterior wall face before backfill is placed, forming the primary water barrier.
A dimple-mat drainage board placed over the membrane intercepts groundwater and directs it away from the wall surface under load.
A perforated drain pipe at the footing collects water from the drainage board and routes it away, preventing pressure buildup at the base of the wall.
Polyurethane or epoxy injection seals active cracks and construction joints, stopping discrete entry points that bypass the exterior membrane.
A cementitious or crystalline coating applied to the interior wall face acts as a secondary vapor barrier after the exterior assembly is in place.
Membrane and drainage placed before backfill goes in.
Exterior membrane work on an already-backfilled structure.
Crack injection and joint sealing for water already entering.
Perimeter drain and weep system added to an existing build.
Why Choose Us
Below-grade waterproofing on clay soil is a different scope than standard basement work, here is what the process looks like on this side.
Every enquiry gets a written review of lot slope, drainage, and clay-soil movement before a builder sees it.
The review covers North Texas groundwater fluctuation and expansive clay conditions specific to the site address.
The written review names the membrane type, drainage board, and perimeter drain scope, not a generic waterproofing quote.
Enquiries are reviewed for below-grade assemblies in DFW clay soil work, not treated as general repair.
The site review notes which permits the waterproofing scope will require before the site visit is arranged.
The Process
01
Share the site address, visible moisture symptoms, and any known soil or drainage issues so the review can start.
02
A written review covering groundwater level, clay-soil movement, crack locations, and permitting scope comes back to you before any builder is contacted.
03
Your enquiry and the written review go forward for a site inspection and a quote on the specific waterproofing assembly needed.

Tell us the lot details and what you are seeing: damp walls, active seepage, or a new build ready for membrane work. The written review covers drainage, clay-soil movement, and permitting scope before anything is quoted.
