SprayWall from Sprayroq is a structural spray-applied polyurethane for sewer, stormwater and potable water infrastructure rehabilitation and protection. The 100 percent VOC-free self-priming corrosion- and abrasion-resistant spray-applied polyurethane coating reinstates structural integrity and provides infiltration control and chemical resistance for concrete, steel, masonry, fiberglass and other surfaces. It is designed for applications on surfaces exposed to acids, corrosives and other caustic elements. Environmental and climatic factors such as freeze/thaw cycling, high humidity or shrinking and swelling soil conditions have minimal effect. It can be applied at any desired thickness in a single mobilization. Its quick curing time allows newly protected structures to be returned to service quickly. It has been extensively third-party tested and provides exceptional ROI with a 50-year design life. 205/957-0020; www.sprayroq.com.
