Blanket Wrap

We are pleased to present our market-leading drainage membranes. We use a complete line of membranes used in dampproofing and waterproofing applications. Whether it is DMX AG Foundation Wrap (Dampproofing Residential Foundations) or DMX 5M (Waterproofing Applications) or DMX Drain 6000 (Deep Foundation Waterproofing Applications), we provide you with everything you will require.


How Does Water Get Into The Basement?

When wet soil comes into contact with unprotected concrete, the concrete acts like a sponge, and actually sucks the moisture in, this is known as CAPILLARY SUCTION. Rainwater that permeates the soil and makes its way towards the basement foundation, is forced against the concrete through HYDROSTATIC LOAD, which is the force of the soil against the foundation. HYDROSTATIC LOAD, pushes water to the concrete, and it can penetrate even the smallest crack in an unprotected concrete foundation. Therefore, to prevent basement leaks, water must not be permitted to come into contact with an unprotected concrete foundation.


Why Is Tar Not Effective?

Traditionally, concrete basements have been dampproofed with a coating of tar, which is sprayed on the foundation. When concrete cures, it cracks, this is very normal for concrete. When the concrete cracks, it also splits the layer of tar that is covering it (as tar has a very low tensile strength), causing entry ways into the basement, for the moisture in the soil. Once the tar splits apart, it cannot repair itself again, in fact, the HYDROSTATIC LOAD can often cause the splits to widen, thereby further exposing the concrete. Also, during backfill, rocks and stones in the soil will often damage the layer of tar, thereby limiting its effectiveness as a dampproofing medium.

How Does DMX AG™ Work? DMX AG™ is made from an Impact Enhanced High Density Polyethelyne Compound known as SL365. SL365 has excellent impact and tensile properties, making it the ideal raw material for DMX AG™. Most importantly, SL365 is inert, it will not harm the environment, and it does not emit hazardous chemicals into the soil around the house, like tar. DMX AG™ is a dimpled sheet. The dimples are approximately 8 mm high, spaced in a symmetrical design of about 20 mm throughout the sheet, from top to bottom. The reason for the dimples is twofold:

  1. When DMX AG™ is applied to the wall, the dimples face the concrete foundation. This creates an air gap of 8 mm (1/4") between the foundation wall and DMX AG™.
  2. The dimples are designed to withstand the HYDROSTATIC LOAD of the soil.

When installed in accordance with the Installation Manual, DMX AG™ prevents water in the soil from coming into contact with the concrete foundation, thereby effectively eliminating the effect of CAPILLARY SUCTION. Even if water somehow gets behind the DMX AG™, it will simply flow down to the footings, as there will be no HYDROSTATIC LOAD, pressing the water against the concrete foundation. When the concrete foundation cures and sets, even the biggest cracks will be protected by DMX AG™, as it covers the entire foundation like a protective blanket. DMX AG™, being made of SL365, is also able to withstand the impact of rocks and stones, effectively protecting the foundation during backfill.



Benefits To The Builder
  • No more costly callbacks to fix leaks in the basement.
  • No waiting for ideal weather conditions, DMX AG™ can be installed in all types of weather, which means that homes can be finished quicker.
  • No hazardous chemicals on the site.
  • Happy homeowners!

The DMX 5M Geocomposite drainage board is manufactured using various combinations of virgin and recycled feed stocks combined with a specific recipe of anti-oxidants, impact modifiers and compatibilizers, which allows DMX Geocomposites to qualify for LEED Point Assessment. The DMX 5M drainage board finished product has a 0.31'’ (8 mm) dimple height, providing a drainage capacity of 12 gal/min/ft of width and a compressive strength of 6,000 lbs/sqft. Polyethylene is highly resistant to chemical interaction and has a life expectancy of up to 50 years when properly installed in accordance with the manufacturer’s instructions. The DMX 5M is well suited to shallow foundation walls (≤ 16 feet), retaining walls, poured or precast concrete walls, insulated concrete forms, prefabricated tilt up walls, below grade chemical gas barrier* and venting system, hill side construction, to compliment any liquid applied waterproofing product for a total systems approach to ground water control. The use of DMX 5M drainage board provides excellent protection of residential and light commercial structural components during the concrete pour and diffuses hydrostatic pressure around any structure to promote positive drainage to outlets. This feature calculates into substantial savings in manpower and materials, a major concern for cost sensitive markets.

The DMX Drain 6000 Geocomposite drainage board is manufactured using various combinations of virgin and recycled feed stocks combined with a specific recipe of anti-oxidants, impact modifiers and compatibilizers, which allows DMX Geocomposites to qualify for LEED Point Assessment. The DMX Drain 6000 drainage board finished product has a 0.40'’ (10 mm) dimple height, providing a drainage capacity of 18 gal/min/ft of width and a compressive strength of 15,000 lbs/sq ft. Polypropylene is highly resistant to chemical interaction and has a life expectancy of up to 50 years when properly installed in accordance with the manufacturer’s instructions. The DMX Drain 6000 is well suited to deep foundation walls, retaining walls, lagging walls, caisson walls, split slabs, below grade chemical gas barrier*, tunnel and subway structural drainage to compliment any liquid applied waterproofing product for a total systems approach to ground water control. The use of DMX Drain 6000 drainage board provides excellent protection of the “blind side" structural components during the concrete pour and diffuses hydrostatic pressure around any structure to positive drainage outlets. This feature calculates into substantial savings in manpower and materials, a major concern when considering infrastructure development costs.
