Ram RB 40 Root Barrier

Ram RB 40 Root Barrier is a heavy duty, linear polyethylene sheet which has been successfully established as an effective root barrier under severe conditions for most intensive vegetated roof systems. Ram RB 40 Root Barrier contains virgin resins which does not become brittle or age prematurely. A typical carbon black content of 2.4% provides excellent protection from UV exposure and harsh weather conditions. Production is carefully controlled to assure a uniform thickness and the material is electronically tested for ASTM conformance. 

Seam taping all joints reduces workmanship demands and installation time.
