COMMERCIAL
WATERPROOFING
IN SHERMAN, TX.
Sherman's $35 billion development boom means new construction alongside a commercial core where buildings average over 40 years old. Whether you're protecting a legacy downtown property or a new facility near Progress Park, moisture infiltration doesn't wait — and neither should your waterproofing plan.
What Commercial Waterproofing Includes
Comprehensive moisture protection for commercial facilities — from elastomeric coatings to full membrane systems.
Elastomeric Coating Systems
Spray-applied or roll-applied flexible coatings that bridge hairline cracks and expand with temperature changes. Ideal for Sherman's commercial masonry buildings where freeze-thaw cycling opens mortar joints each winter.
We apply coatings rated for multi-story substrates — concrete, CMU, brick, and stucco — with proper surface profiling to ensure adhesion that lasts 10-15 years between recoats.
Membrane Waterproofing
Self-adhering and torch-applied sheet membranes for below-grade walls, plaza decks, and parking structures. These create a continuous moisture barrier where elastomeric coatings alone can't handle hydrostatic pressure.
Critical for Sherman's clay-heavy Grayson County soils, which expand when wet and exert lateral pressure on foundation walls — a leading cause of below-grade water infiltration in commercial buildings here.
Sealant & Joint Replacement
Expansion joints, control joints, and perimeter sealants are the first line of defense — and the first to fail. We remove deteriorated caulking, prepare substrates, and install commercial-grade silicone, polyurethane, or polysulfide sealants matched to your building's movement characteristics.
On multi-story Sherman buildings, we use our 56' and 72' boom trucks for efficient access without scaffolding, reducing cost and timeline.
Penetrating Masonry Sealers
For historic masonry buildings — including structures along Sherman's downtown Travis Street corridor — penetrating sealers absorb into the substrate without changing appearance. They repel water while allowing the masonry to breathe, preventing the trapped-moisture deterioration that film-forming coatings can cause.
We evaluate substrate porosity, mortar condition, and previous treatment history before recommending a sealer system.

Why Sherman Buildings Need Waterproofing Now
Sherman is the county seat of Grayson County and home to a commercial building stock where the median structure dates to 1980 — meaning many of the buildings along US-82, Travis Street, and the downtown historic district are approaching or past the 40-year mark where original waterproofing systems fail.
At the same time, Sherman is in the middle of the largest private investment in North Texas history. Texas Instruments' $30 billion semiconductor fabrication campus and GlobiTech's $5 billion wafer plant are transforming the area. The construction boom brings new commercial buildings that need proper waterproofing from day one — and demand for tenant-ready older buildings that need envelope restoration to compete.
Located just 16 miles from our Whitesboro headquarters, Sherman is in our core service area. We've worked on commercial buildings across Grayson County and understand the specific challenges — from the clay soils that pressure foundations to the severe weather corridor that delivers 2-3 major hail events annually.

Commercial Waterproofing FAQ
What is commercial waterproofing and why does my building need it?
Commercial waterproofing protects your building envelope from moisture infiltration that causes structural deterioration, mold growth, and tenant complaints. In Sherman, where buildings along Travis Street and US-82 average over 40 years old, aging sealants and cracked masonry are the most common entry points. Professional waterproofing extends your building's lifespan and prevents costly interior damage.
What are the signs that a commercial building needs waterproofing?
Look for water stains on interior walls or ceilings, efflorescence (white mineral deposits) on exterior masonry, bubbling or peeling paint on exterior surfaces, visible cracks in mortar joints, and musty odors in lower levels. Grayson County's clay-heavy soils and seasonal temperature swings from North Texas weather accelerate sealant degradation — if your building was last waterproofed more than 10 years ago, an inspection is overdue.
How is commercial waterproofing different from residential?
Commercial waterproofing addresses larger surface areas, multiple substrate types (concrete, masonry, curtain wall, metal panel), and stricter code requirements. Commercial buildings also require phased application to keep tenants operational. We use industrial-grade elastomeric coatings and membrane systems rated for multi-story structures — not the consumer-grade sealers used on residential foundations.
What types of waterproofing systems are used on commercial buildings?
The three primary systems are elastomeric coatings (spray- or roll-applied flexible membranes), sheet membrane systems (self-adhering or torch-applied), and penetrating sealers for masonry substrates. The right choice depends on your building's construction type, exposure conditions, and maintenance access. For Sherman's older masonry commercial buildings, we often combine tuckpointing with penetrating sealers for a comprehensive moisture barrier.
How often should commercial waterproofing be inspected?
We recommend annual visual inspections and a professional assessment every 3-5 years. After significant weather events — North Texas averages 2-3 severe hail events per year — inspect immediately. Catching a failed sealant joint early costs a fraction of repairing the water damage it causes downstream.
