TRST PPWR-Series Woven PP/PE for Hydraulic Environment is manufactured with in-woven loops to facilitate the fabrication of fascine mattress for easy launch and installation in the marine and hydraulic environment. The in-woven loops are strong and spaced at convenient grid intervals to provide tie-up point to attach fascine material. The fascine not only increases stiffness to the erosion control mattress during fabrication, positioning and installation., but also it provides extra resistance against rock or rip-rap sliding or rolling down the mattress, when it is placed on a slop or in high velocity current.
