Outstanding compressive strength and high-water flow rate characterize this premium commercial-grade drainboard. Its high-strength core provides a continuous path for water discharge, eliminating the potential for build-up of hydrostatic pressure.
The non-woven geotextile allows water to pass freely into the drainage core. At the same time, it prevents the passage of soil particles to ensure that the drainage core doesn’t get clogged. The geotextile meets AASHTO M288 Class 3. The special copolymer polypropylene provides unmatched tear, puncture and chemical resistance, and – unlike polystyrene drainboard imitations – is unaffected by environmental stress cracking.
