The Problem

Without a proper drainage system, water can damage virtually any construction project. A drainboard controls the flow of water, taking it out and away from the foundation. Behind the drainboard, waterproofing remains soft to some extent and is susceptible to cold flow under pressure. Rather than breaking or cutting, some waterproofing material may flow into the drainboard dimples over time, form a bubble, and eventually burst – compromising the waterproofing system. To prevent this from occurring, a special type of drainage board with a protective polyethylene sheet must be applied.  

The Solution

DELTA®-DRAIN 6200 HI-X is a heavy-duty drainboard with an adhered polymeric protection sheet, ideally suited for projects in need of protection against die cutting of waterproofing membranes.

For even more advanced protection than the DELTA®-DRAIN 6000 HI-X, look to DELTA®-DRAIN 6200 HI-X.

Although both products have the same compressive strength, DELTA®-DRAIN 6200 HI-X features a linear Low-Density Polyethylene (LDPE) sheet adhered to the cup side of the dimples. The protection sheet prevents viscous flow and die cutting of soft liquid or sheet-applied waterproofing membranes.

Product Benefits
  • 3-layer drainage composite
  • Consists of a dimpled drainage core, a high-strength, needle punched, non-woven polypropylene geotextile, and a polymeric protection sheet adhered to the back side of the drainage core 
  • Outstanding compressive strength and high water flow rate characterize this commercial grade drainboard
  • Specifically designed for use over waterproofing membranes, the high-strength polymeric film adhered to the back side of the drainage core prevents potential die cutting into the waterproofing membrane
  • Non-woven, needle-punched geotextile prevents the passage of soil particles but allows water to pass freely, ensuring that the drainage core will not get clogged
  • Core provides a continuous path for water discharge, eliminating the potential for build-up of hydrostatic pressure
  • Geotextile is fully bonded to the drainage core, which prevents it from being pushed into the flow channels by the load from adjacent back-fill material
  • Extremely high compressive strength (> 15,000 psf) – can be used at installation depths of 45 ft. and more
  • One of the only drainboards on today’s market made out of a special copolymer polypropylene, which is dramatically stronger than polystyrene imitators, resisting jobsite damage and rough handling
  • Unaffected by environmental stress cracking
  • Available in two roll sizes (4'x50' or 6’x50')
