DELTA^®-DRAIN is an effective method to control the flow of damaging soil moisture though cracks and gaps in below grade structures, while relieving hydrostatic pressure.  It is comprised of a multi-layer geocomposite combining a high compressive strength core with a geotextile, bonded to the core for lasting durability.  DELTA^®-DRAIN creates an essential path for the vertical and horizontal drainage of soil moisture and filtering of soil particles.  DELTA^®-DRAIN has been successfully used in a wide variety of exterior applications where redirection of ground water and pressure relief are primary concerns.  DELTA^®-DRAIN large size makes installation faster.  Extra width means less material overlap, less seams, less labor, which leads to an important point--less cost.  DELTA^®-DRAIN is typically used in conjunction with liquid and sheet applied waterproofings and as a stand alone drainage composite for civil engineering applications. 
 

Applications:
 •  Tunnel construction
 •  Drains off water from underground walls and structures by placing sheets vertically
 •  Retaining Walls
 •  Canals
 •  Hydrostatic pressure relief

DELTA^®-DRAIN 6000
The DELTA^®DRAIN 6000   system is the heavy duty version of the DELTA^®DRAIN 2000.  DELTA^®DRAIN 6000  system  consists of a three-dimensional, tear  resistant polymeric  core and non-woven, needle-punched  filter geotextile.  Fully  bonding the geotextile  to the core’s dimples prevents  the  geotextile from  being  pushed  into the  flow channels by back-fill.  Water can pass freely and easily through the geotextile and into the drain core where gravity feeds it into the drainage system and pipes.

 Applications:
 •  Below grade waterproofing
 •  Pilewall drainage
 •  Lagging wall drainage
 •  Bridge abutments
 •  Roof decks
 •  Hydrostatic pressure relief

DELTA^®-DRAIN 6200

DELTA^®DRAIN 6200 is a specially manufactured version of DELTA^®DRAIN 6000 offering the unltimate in drain  solutions that  incorporates a plastic  sheet  adhered to the back surface of the drain core.  This plastic sheet offers a protective layer on the flat side  of the plastic core to prevent die cutting of soft liquid or sheet applied waterproofing membrane.

DELTA^®DRAIN 6200 can also be used in lagging wall applications.  Additionally, the plastic backing on DELTA^®DRAIN 6200 can act as a slipsheet between the drain board and the adjacent structure.

Applications:
 •  Below grade drainage in conjunction with liquid and sheet applied waterproofing
 •  Foundation walls
 •  Parking decks - vertical applications
 •  Hydrostatic pressure relief

DELTA^®-DRAIN 9000
DELTA^®DRAIN  9000  is a high-strength,  high  performance  drain  board  ideally suited for demanding horizontal  applications in  plaza deck,  split slab  and horizontal  flat work and pavement construction.  DELTA^®DRAIN 9000  utilizes a high-strength woven monofilament filter fabric that offers ideal drainage and support under concrete, soil and beddings.

Applications:
 •  Plaza decks
 •  Garden roofs/terraces
 •  Earth shelters
 •  Split slab construction
 •  Planter boxes
 •  Parking decks - horizontal applications

 

It is well known that moisture can be a major source for trouble in construction.  In building envelopes and wall cavities moisture can cause mold, mildew, and major decay, whether the origin of moisture is rainwater that passes the exterior cladding, or condensing vapor from the interior.   DELTA^®-DRY provides a unique approach to manage both, moisture from inside and outside in order to protect the wall cavity against moisture damage.

DELTA^®-DRY is an impermeable membrane made out of a special high-density polyethylene that provides two-sided drainage through its dimple and groove design.  The structured membrane provides a protective weather resistive barrier with complete capillary break for residential and commercial building structures.  It protects the building from water intrusion behind the exterior cladding (i.e. wind driven rain) by draining it back out to the exterior.  DELTA^®-DRY allows water vapor, driven from the interior to the exterior to escape through the air space between exterior sheathing board and membrane, while minimizing the potential for condensation that could cause damage in the wall cavity.

Due to the double sided dimple structure of the membrane breathability is provided on both sides of the product, allowing moisture to escape behind siding, brick veneer, or any other approved exterior cladding.  At the same time DELTA^®-DRY impedes solar-driven moisture towards the interior of the structure as it occurs with conventional stucco, brick veneer, or any other absorptive cladding material.  In addition the membrane helps to save energy by reflecting radiation heat - keeping heat outside in the summer, and warmth inside in the winter.

DELTA^®-DRY is designed to be installed on the exterior sheathing board (OSB) as a substitute for conventional sheathing membranes (i.e. building paper).  It may also be installed over breather type sheathing membranes or building paper.  Top and bottom edge of the membrane are ventilated (allow for air movement).  The material is easy to cut with a utility knife.  Seams are simply overlapped (shingled) by approximately 3 inches.  Window and door cut-outs are to be wrapped with a self-adhesive flashing material along the bottom sill and the side jambs.  Exterior cladding material can be installed as usual right on top of DELTA^®-DRY.

The performance of this innovative weather resistive barrier has been validated through testing at the University of Waterloo and Oak Ridge National Laboratory.
