The Problem

Without a proper drainage system, water can damage virtually any construction project. An improperly installed system or a waterproofing system that lacks a drainage system can allow hydrostatic pressure to build, making any crack in the foundation an access for water damage.  

The Solution

DELTA®-DRAIN 6000 HI-X is the ideal solution for applications where high drainage capacity is required. Whether in commercial or civil engineering applications, this drainboard has proven superior long-term performance. Its outstanding impact resistance helps it maintain the integrity of the dimpled core even under tough conditions.

DELTA®-DRAIN 6000 HI-X is a heavier duty drainage system, and has a higher compressive strength than the DELTA®-DRAIN 2000 HI-X.  

Product Details
Product Benefits
  • 2-layer drainage composite
  • Composed of a high-strength, needle punched, non-woven polypropylene geotextile
  • The geotextile is fully bonded to the dimpled drainage core 
  • Outstanding compressive strength and high water flow rate characterize this commercial grade drainboard
  • 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
  • Highly effective drainage system for underground wall construction, pile and lagging wall drainage, retaining walls, bridge abutments, and as relief layer for hydrostatic pressure on any subsurface structure
  • Available in two roll sizes (4'x50' or 6’x50’)
