COMMERCIAL
WATERPROOFING
IN DURANT, OK.
Durant is home to a 1.2 million sq ft Big Lots distribution center, a $250M Commercial Metals micro-mill, the Choctaw Nation's $600M resort complex — and a downtown historic district with buildings dating to 1901. That's the widest envelope maintenance spread of any market in southeastern Oklahoma, and it requires expertise across both industrial-scale waterproofing and historically sensitive masonry work.
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. For Durant's western industrial zone — where Big Lots' distribution center, the Commercial Metals micro-mill, and Cardinal Glass Industries operate enormous tilt-wall and concrete structures — elastomeric coatings provide the continuous moisture barrier that keeps production facilities dry through Oklahoma's ice storms, hail events, and high-wind season.
We apply coatings rated for multi-story and industrial substrates 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. Southeastern Oklahoma State University's 269-acre campus — 62 buildings spanning over a century of construction — requires membrane waterproofing on plaza decks and below-grade connections between older brick buildings and modern academic additions.
The Choctaw Nation's Sky Tower, opened in 2021 as a 21-story, 1,000-room structure, represents the kind of large mixed-use development where proper membrane waterproofing on podium decks and parking levels is essential from the first maintenance cycle onward.
Sealant & Joint Replacement
Expansion joints, panel-to-panel sealants, and window perimeter caulking are the first line of defense — and the first to fail on Durant's 40-year-average commercial stock. 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 US-69/75 and US-70 corridors, we use our 56' and 72' boom trucks for efficient access without scaffolding — minimizing disruption to active retail and commercial operations.
Penetrating Masonry Sealers
For Durant's Downtown Historic District — buildings constructed 1901-1957 in Classical Revival, Mission Revival, and Art Deco styles on the National Register — penetrating sealers absorb into the substrate without altering historic character. They repel water while allowing 70-120 year old masonry to breathe, preventing the trapped-moisture spalling that film-forming coatings cause on pre-war brick construction.
Southeastern Oklahoma State University's early 20th century brick buildings require the same historically sensitive approach — we evaluate substrate porosity, mortar composition, and previous treatment history before specifying any sealer system.

Why Durant Buildings Need Waterproofing Now
Durant is Bryan County's dominant commercial hub — the city where the Choctaw Nation opened a $600M resort expansion with a 21-story Sky Tower in 2021, where Big Lots built one of the largest distribution centers in southeastern Oklahoma in 2004, and where Commercial Metals Company dedicated a $250M micro-mill in 2018. That scale of investment sets a high bar for building condition across the entire commercial market.
The average Durant commercial building, with a median year built of 1983, has crossed the 40-year mark — the threshold at which concrete spalls, masonry repointing becomes mandatory, and waterproof membranes on flat-roofed retail and industrial buildings typically require full replacement. The Downtown Historic District's buildings go back to 1901, with Southeastern Oklahoma State University's campus spanning founded-1909 brick structures alongside modern facilities. Each era requires a different treatment approach.
Griffin Restoration is licensed in both Texas and Oklahoma. From our Whitesboro headquarters, we serve southeastern Oklahoma including Bryan County — with the boom truck access and multi-substrate expertise that Durant's varied building inventory demands.

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. Durant's western industrial zone hosts three enormous facilities built within the last 25 years — Big Lots' 1.2M sq ft distribution center (2004), Commercial Metals Company's $250M micro-mill (2018), and Cardinal Glass Industries' float glass plant — each requiring ongoing waterproofing maintenance at industrial scale. Beyond the industrial corridor, Durant's average commercial building is over 40 years old (median year built: 1983), and the Downtown Historic District contains structures dating to 1901. Waterproofing requirements span every era of construction in this city.
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. Durant sits at the southern reach of Tornado Alley, where the combination of hail, high winds, and ice storms creates recurring envelope stress. For the 40+ year old commercial buildings along US-69/75 and in the Downtown Historic District, Oklahoma's severe weather cycle compounds the natural aging of original waterproofing systems — regular inspections are essential.
How is commercial waterproofing different from residential?
Commercial waterproofing addresses larger surface areas, multiple substrate types (concrete, CMU, brick, tilt-wall, historic masonry), and stricter code requirements. Durant's commercial inventory spans extremes: Big Lots' 1,200,000-sq-ft distribution center requires industrial-grade tilt-wall panel sealants and roof-to-wall transitions across an enormous footprint, while Durant's Downtown Historic District buildings — constructed 1901-1957 in Classical Revival, Mission Revival, and Art Deco styles — require historically sensitive penetrating sealers and lime-compatible tuckpointing. We have experience across both ends of this spectrum.
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 Durant's major industrial facilities in the western zone, full sealant replacement at tilt-wall panel joints combined with elastomeric coatings is the standard approach. Southeastern Oklahoma State University's 269-acre campus — 62 buildings spanning early 20th century brick to modern academic construction — requires a mixed approach: penetrating sealers for historic masonry and membrane waterproofing for plaza decks and below-grade areas on newer structures.
How often should commercial waterproofing be inspected?
We recommend annual visual inspections and a professional assessment every 3-5 years. Durant's position in the southern reach of Tornado Alley — with frequent hail, high winds, and ice storms — means weather events should trigger immediate envelope inspections. For AllianceHealth Durant's 148-bed hospital campus, which serves five counties, Joint Commission standards effectively require documented exterior maintenance records. For industrial and distribution facilities where production downtime from water infiltration carries direct cost consequences, staying ahead of the inspection cycle is the most cost-effective maintenance strategy available.
