Protective needlepunch felt: used for cushioning waterproofing membranes. 8oz. or 12 oz. felts are used as an underlayment for other protective layers such as drainage panels. 16 oz. felts are used when gravel or soil will be placed on top.
Separation needlepunch felt: Our felts have good permittivity, allowing for free water flow. The low tensile strength allows roots to readily penetrate. This felt is also used to facilitate the distribution and storage of water within the root zone.
