COMMERCIAL
WATERPROOFING
IN GREENVILLE, TX.
L3Harris has operated at Majors Field since 1942 — accumulating more than 3.7 million square feet of hangars, manufacturing buildings, and test facilities across 1,500 acres over 80+ years. That's an enormous envelope liability for deferred maintenance. Doppler radar has recorded 85 separate hail events near Greenville, and every flat-roof industrial building in this corridor absorbs that damage cumulatively.
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 Greenville's large-footprint industrial buildings in Industrial Park West (SH-380) and the Air Park area, where tilt-wall concrete panels and masonry block construction develop panel-joint cracks as the building settles over decades.
We apply coatings rated for multi-story and industrial substrates — concrete, CMU, brick, and tilt-wall — with proper surface profiling to ensure adhesion that lasts 10-15 years between recoats and holds up under the 85+ hail events documented near this area.
Membrane Waterproofing
Self-adhering and torch-applied sheet membranes for below-grade walls, plaza decks, and parking structures. Hunt Regional Medical Center's campus — which added a 31,000-sq-ft expansion in 2021 — requires continuous membrane waterproofing at below-grade connections and elevated walkways to meet Joint Commission facility standards.
Hunt County's Blackland Prairie clay soils cause seasonal shrink-swell cycles that open facade cracks and compromise waterproofing membranes — membrane systems provide the hydrostatic resistance that coatings alone cannot deliver on below-grade applications.
Sealant & Joint Replacement
Expansion joints, panel-to-panel connections, and perimeter sealants are the first to fail on Greenville's 1960s-1980s industrial buildings. We remove deteriorated caulking, prepare substrates, and install commercial-grade silicone, polyurethane, or polysulfide sealants matched to each building's movement and thermal characteristics.
For multi-story structures along the I-30 corridor, we use our 56' and 72' boom trucks for efficient access without scaffolding — critical for keeping logistics and manufacturing operations running during envelope work.
Penetrating Masonry Sealers
For Greenville's downtown Main Street historic district — brick and masonry buildings on the National Register from the early 1900s with endemic mortar deterioration and failed window perimeter sealants — penetrating sealers absorb into the substrate without altering the historic character. They repel water while allowing the masonry to breathe.
We evaluate substrate porosity, mortar condition, and previous treatment history before specifying a sealer system appropriate for historic masonry ages and compositions common to early 20th century downtown commercial construction.

Why Greenville Buildings Need Waterproofing Now
Greenville's identity as an industrial and defense manufacturing city stretches back to 1942, when Majors Airport opened as a WWII Army Air Forces advanced flying school. L3Harris (through successive acquisitions from TEMCO) has been the city's dominant employer for over 75 years — accumulating more than 3.7 million square feet of facility space across the 1,500-acre Majors Field campus that spans eight decades of construction.
Greenville's median year built of 1979 reflects industrial and retail construction concentrated in the post-war boom. The Industrial Park West corridor along SH-380 and the I-30 interchange area contain 1960s-1980s tilt-wall and masonry structures where original waterproofing has long since passed its service life. As the I-30/US-380 position attracts logistics tenants with choices across a wide geography, facade condition is a direct factor in leasing decisions.
Doppler radar has recorded 85 separate hail events near Greenville, and the May 8, 2024 golf ball-sized hail event underscored the ongoing risk for flat-roof industrial buildings. Large uninterrupted roof and wall surfaces accumulate envelope damage faster than smaller structures — and the consequences of water infiltration in manufacturing or distribution facilities are immediate and costly.

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 Greenville, the industrial corridor along I-30 and at Majors Field contains an enormous concentration of large-footprint buildings — hangars, manufacturing facilities, tilt-wall warehouse structures — accumulated over decades. Many date to the 1960s-1980s with long-since-expired original waterproofing. For facility managers responsible for these assets, proactive waterproofing prevents the kind of interior damage that disrupts production operations and triggers costly emergency repairs.
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 or coating on exterior surfaces, visible cracks in mortar joints or tilt-wall panel connections, and musty odors in lower levels. Hunt County's Blackland Prairie clay soils cause seasonal shrink-swell cycles that open facade cracks at mortar joints and compromise waterproofing membranes. After the May 8, 2024 golf ball-sized hail event and any of the 85 documented hail events near Greenville, exterior inspections are critical — large flat-roof industrial buildings are particularly vulnerable to cumulative envelope damage.
How is commercial waterproofing different from residential?
Commercial waterproofing addresses larger surface areas, multiple substrate types (concrete, CMU, brick, tilt-wall panels, metal cladding), and stricter code requirements. Industrial facilities at Majors Field and the I-30 corridor often involve large-span tilt-wall construction where panel-to-panel sealant joints span the full height of the building — a single failed joint can admit water across thousands of square feet of interior space. We use industrial-grade elastomeric coatings and membrane systems rated for these 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. For Greenville's industrial inventory, elastomeric coatings applied to tilt-wall and masonry substrates are the most common primary system, combined with full sealant replacement at panel joints. Hunt Regional Medical Center's campus requires membrane waterproofing on plaza decks and below-grade areas meeting Joint Commission maintenance standards. Downtown Main Street historic masonry buildings use penetrating sealers to maintain character while blocking moisture.
How often should commercial waterproofing be inspected?
We recommend annual visual inspections and a professional assessment every 3-5 years. After significant weather events — Doppler radar has recorded 85 separate hail events near Greenville, including golf ball-sized hail (1.75 inches) on May 8, 2024 — inspect immediately. For Greenville's large industrial buildings in the I-30 logistics corridor, where competing new tilt-wall construction sets tenant expectations for building condition, maintaining a documented inspection history is also a leasing and property-value asset.
