These Drainboard Systems Help Commercial Buildings Meet Horizontal, Vertical and Blindside Drainage Requirements

DELTA-TERRAXX and DELTA-TERRAXX PLUS are drainboard systems for horizontal, vertical and blindside drainage requirements in commercial applications. This high-performance option can meet higher building code requirements and urban water management standards easily.

Both products feature a TYPAR geotextile bonded to a dimple sheet, which allows for a higher drainage capacity than the average mineral-drainage layer. The geotextile can withstand heavy structural loads, backfill and soil overburden, so the drainage space won’t clog and the drainage capacity stays steady. The PLUS drainboard has a self-adhering edge tab that makes installation fast and consistent; installers roll out the sheets and stick them together.
