A true concrete equipment pad at the weight of plastic (about 2.5 lb/sq-ft). UltraLite® is strengthened by miles of fiber in each square foot of fiber-cement coating. This fiber allows the pad to flex instead of cracking or breaking. The textured surface prevents the condensing unit or portable generator from sliding, and allows water drainage, while the engineered expanded polystyrene (EPS) core prevents warping and provides a solid bottom to resist settling. Unaffected by soil conditions, ultraviolet (UV) light, temperature extremes, and other weather conditions. Where codes have moved toward requiring 3 in pads, UltraLite® is the solution. Check localcodes for your requirements. Diversitech UltraLite® Concrete Equipment Pad, Lightweight, 38 in Length, 18 in Width, 3 in Height, For Use With: Air-Conditioning Compressor and Condensing Unit, Gray, Domestic
