DELTA-DRAIN 6200 HI-X is a commercial-grade, 3-layer drainage composite manufactured by Dörken Systems Inc. It's built for below-grade walls and parking decks where waterproofing membranes need protection at installation depths of 45 feet or more. Unlike standard drainboards, 6200 HI-X adds a linear low-density polyethylene (LDPE) sheet to the drainage core, specifically to stop soft waterproofing membranes from being die-cut or forced into the board's dimples under pressure over time.

What Is DELTA-DRAIN 6200 HI-X?

DELTA-DRAIN 6200 HI-X is a heavy-duty drainage board designed to sit directly against a waterproofed below-grade wall or parking deck surface. Its job is twofold: relieve hydrostatic pressure by giving groundwater a continuous path to drain away from the structure, and physically shield the waterproofing membrane behind it from damage during backfill and over the life of the structure.

It's part of Dörken's vertical drainage composite lineup, alongside DELTA-DRAIN 2000 HI-X and DELTA-DRAIN 6000 HI-X, and is manufactured by Dörken Systems Inc.

The Problem It Solves

Some liquid- and sheet-applied waterproofing membranes can remain relatively soft or susceptible to deformation under sustained pressure. That softness is part of how they seal, but it also creates a trade-off: those membranes are susceptible to "cold flow" under sustained pressure. Over time, backfill load can push that soft membrane material into the dimples of a standard drainboard. It can form a bubble and eventually burst, compromising the waterproofing system it was meant to protect.

That failure mode is one of the key issues 6200 HI-X is engineered to help prevent. Instead of relying on the drainage core alone, Dörken added a protective film layer specifically to keep the membrane from ever contacting — and flowing into — the drainboard's dimples.

How the 3-Layer Composite Is Built

DELTA-DRAIN 6200 HI-X is a 3-layer composite, with each layer doing a distinct job:

Layer	Material	What It Does
Drainage core	Dimpled, high-strength copolymer polypropylene	Creates a continuous channel for water discharge, preventing hydrostatic pressure buildup against the structure
Geotextile	Needle-punched, non-woven polypropylene fabric	Lets water pass freely into the core while filtering out soil particles so the drainage channels don't clog; fully bonded to the core so it can't be pushed into the flow channels under backfill load
Protection sheet	Linear low-density polyethylene (LDPE) film, adhered to the cup side of the dimples	Prevents viscous flow and die-cutting of soft liquid- or sheet-applied waterproofing membranes installed behind the board

The flat, film-protected side installs against the waterproofed wall; the geotextile faces outward toward backfill.

What Makes 6200 HI-X Different From 6000 HI-X

This is the question we hear most from specifiers, so it's worth being precise: DELTA-DRAIN 6200 HI-X and 6000 HI-X share the same compressive strength. The difference is the LDPE protection sheet adhered to the cup side of the dimples on the 6200 HI-X. That extra layer makes 6200 HI-X the better choice specifically when the waterproofing membrane behind it is soft, liquid-applied, or otherwise vulnerable to die-cutting and cold flow.

If your project uses a firmer membrane where that risk is lower, 6000 HI-X may be sufficient. For a full side-by-side breakdown, see our dedicated DELTA-DRAIN 6200 HI-X vs. 6000 HI-X comparison.

Who Uses DELTA-DRAIN 6200 HI-X

DELTA-DRAIN 6200 HI-X is primarily designed for demanding commercial and professional waterproofing applications and is commonly specified or purchased by:

• Waterproofing contractors and applicators installing protection courses over liquid- or sheet-applied membranes on below-grade walls
  
• General contractors managing parking deck or foundation wall packages that require hydrostatic pressure relief at depth
  
  
• Architects and specification writers drafting Division 07 (Thermal and Moisture Protection) documents who need a drainboard rated for 45+ ft installations
  
  
• Building envelope consultants evaluating drainage composite options for deep foundation or subsurface structure projects
  
  
• Distributors and buyers sourcing in bulk for commercial waterproofing jobs

If your project's waterproofing membrane is soft or liquid-applied and your excavation goes beyond typical residential depths, 6200 HI-X is specifically designed to address that combination of drainage and membrane-protection requirements.

Installation Basics

The film-protected (flat) side of DELTA-DRAIN 6200 HI-X installs directly against the waterproofed wall surface, with the geotextile facing outward toward backfill. Dörken publishes full installation instructions, a 3-part guide specification, and a technical memorandum specifically covering top-edge installation — all linked below. Because correct orientation and edge treatment affect long-term performance, always install per Dörken's current published guidance rather than general drainboard assumptions.

Compatible Accessories

Dörken pairs 6200 HI-X with several accessories to complete the installation:

• DELTA-GRIP FASTENER — self-adhesive fastener for securing DELTA-DRAIN and other DELTA drainage composites
  
  
• DELTA-MOLD STRIP — used to finish installations around windows, doors, or grade changes in the foundation
  
  
• DELTA-SCREW FASTENER — fixes drainboard to perimeter insulation without penetrating the waterproofing membrane

FAQs

What is DELTA-DRAIN 6200 HI-X used for?
DELTA-DRAIN 6200 HI-X is used as a heavy-duty drainage and protection layer over waterproofing membranes in demanding below-grade applications. Its high compressive strength allows it to be used at installation depths of 45 ft. and greater.

Is DELTA-DRAIN 6200 HI-X a waterproofing membrane?
No. DELTA-DRAIN 6200 HI-X is a drainage and protection composite designed for installation over a waterproofing membrane. It provides a drainage path for water while its protective backing helps shield the waterproofing membrane from damage.

What's the difference between DELTA-DRAIN 6200 HI-X and 6000 HI-X?
They share the same compressive strength, but 6200 HI-X adds an LDPE protection sheet on the cup side of the dimples to prevent die-cutting and viscous flow of soft waterproofing membranes — a layer 6000 HI-X doesn't have.

How deep can DELTA-DRAIN 6200 HI-X be installed?
Its compressive strength (greater than 15,000 psf) supports installation depths of 45 ft. and more.

Is DELTA-DRAIN 6200 HI-X suitable for liquid-applied waterproofing membranes?
Yes — its LDPE protection sheet was specifically added to prevent die-cutting and cold-flow damage to soft, liquid- or sheet-applied membranes.
