Terram Drainage Composites

Product Description

Terram composites are manufactured using polyethylene and polypropylene which both offer high resistance to chemical and bacterial degradation. Terram composites are bonded using heat lamination.

Terram B1 consists of a drainage net with a filter geotextile which forms a cost effective drainage layer as an alternative to granular materials.

Terram 1B1 (formerly Filtram 1B1) consists of a drainage net with a filter geotextile on both sides which forms a cost effective drainage layer as an alternative to granular materials. When used in conjuction with a waterproofing system, Terram 1B1 provides drainage and provides protection against damage to the waterproofing.

Terram 1BZ combines an impermeable membrane, drainage net and filter geotextile which together form a drainage layer with added waterproofing function. Terram 1BZ may be used to compliment a proprietary tanking system.
