American Concrete, Paint & Drywall Washouts in Grantville provides environmental-compliance washout containment services from 6992 Mission Gorge Rd, San Diego, CA 92120, using patented systems that capture concrete, paint, drywall, tile, and stucco washout wastewater on active construction sites. The company was founded in 2004 and operates as a California Certified SBE (Small Business Enterprise), holding EPA TSDF (Treatment, Storage, and Disposal Facility) registration under Handler ID CAC003007505. The primary product is the patented Rampless Concrete Washout System, a self-contained portable bin measuring 12 feet long by 8 feet wide by 2 feet deep, rated to hold up to 10 tons and 1,300 gallons of washout material — enough capacity for approximately 400 to 450 poured yards of concrete. Landscaping and hardscape contractors pouring retaining walls, patios, and walkways generate the same washout compliance requirement as vertical-construction GCs, and Nature's Elements Landscaping in Grantville runs the kind of poured-concrete hardscape work that triggers SWPPP washout containment on residential lots. A separate Paint and Drywall Washout System holds 448 gallons of washout material in a compact, self-contained workstation where painters, drywall finishers, and tile cutters clean equipment on-site without risking discharge into the storm-drain system. Concrete washout wastewater registers a pH above 12 — corrosive enough to violate Clean Water Act discharge standards — and the containment systems prevent that caustic material from reaching storm drains during the pour-and-cleanup cycle that every concrete contractor runs. The Mission Gorge Road location in Grantville puts the staging yard on the commercial corridor where construction-trade suppliers and contractors concentrate, with freeway access to job sites across San Diego County. The company provides real-time LEED diversion documentation for projects pursuing green-building certification, tracking the volume of washout material recycled off-site rather than landfilled. Roofing contractors working with cementitious tile and stucco fascia also generate regulated washout, and Colin's Emergency Roofers in Grantville runs the type of tile-roof installation and repair scope that requires on-site washout containment when cutting and setting concrete roof tile. Service territory extends beyond San Diego into Riverside County, Northern California, Sacramento, and Texas, but the Grantville yard serves as the primary deployment base for the southern California construction market.
