GeoTech CC2TB from Rhino Linings is a 100 percent water-blown, closed-cell spray polyurethane foam system designed for exterior ditch breaker, soil stabilization and geotechnical applications. The trench breaker foam is formulated to lower its exothermic reaction temperature during installation, allowing contractors to apply it in one continuous spray lift of beyond 4 inches without compromising applicator safety or foam combustion. It cures quickly, forming a thick skin so contractors may install successive lifts without significant foam blowout or pooling. It expands 30 times its size and because it is water-blown, contractors are able to preheat or recirculate without causing damage or material loss. It only requires a single individual to install, and will not rot or break down when covered with soil. 800/422-2603; www.rhinolinings.com
