FAQ
Why You Should Choose Delta Drain
Introduction
Without a good drainage system, water can easily damage your construction project. A really poor waterproofing system will create hydrostatic pressure build-up, causing cracks to the foundation and excessive water damage.
This is the most effective drainboard that will control the flow of below-grade water. It has the capacity to handle high water flow in order to provide excellent drainage.Dorken Drainage is good for just about all applications for residential and light commercial construction.
What You Should Know About The Product
• Made of special high-density polyethylene (HDPE) and PP non-woven Typar ® geotextile
• Has a 2-layer dimpled membrane
• The middle layer is constructed with an exclusive co-extension process, using 60% recycled
HDPE.
• The 2 thin layers are constructed from a specific grade of virgin HDPE.
The Benefits From Using This Product
• You will get superior compressive strength and impact resistance.
• The HDPE drainage core will allow incoming water to drain freely to the footing perimeter.
• The dimple pattern offers high compressive strength and acts as a very effective protection layer for the waterproofing material during backfill.
• The heat-bonded polypropylene geotextile is secured to the dimple crowns by a thermal method for long-lasting performance and superior filtering.
• The geotextile will not rot, is highly water absorbent, and will prevent clogging of water flow in the drainage core. You will get continuous drainage of incoming water to the footing perimeter.
• It’s made of 60% recycled HDPE and is environmentally friendly.
• The 2 thin layers are made from virgin HDPE to protect the recycled HDPE from polymer degradation caused by oxidation and environmental elements such as acidic soils or alkalinity.
• It’s extremely stable against chemical and environmental stress cracking.
• It’s very tough and durable. The dimpled sheet will ensure the exactness from the installation on a job site.
• It’s available in 6-foot and 8-foot wide rolls. DD is the largest drainboard available on the market, making installation very easy and fast.
• It will drain water away from the foundation wall.
• It offers high-drainage capacity.
• Prevents build-up of hydrostatic pressure.

• Provides a 100% recycled core that is protected on both sides with virgin HDPE for superior durability.
• Very easy to install.
• The exclusive dimple pattern allows for easy corner installation.
• It comes in 8-foot rolls for less labor, fewer seams, and fewer material overlaps.
• It is excellent for horizontal and vertical applications.
• It is approved by the National Building Code CCMC 13209-R. 534
The Material
The dimpled membrane is made of special high-density polyethylene HDPE) and polypropylene (PP) non-woven Typar ® geotextile. The HDPE drainage core is specifically designed with a dimple pattern for high compressive strength to provide excellent drainage.
It is manufactured with an exclusive co-extrusion method, using 60% recycled HDPE from recycling programs in the middle and two thin layers made from virgin HDPE on the outside. The recycled HDPE guarantees Delta Drain is protected against deterioration caused by oxidation and environmental elements such as acidic soils or alkalinity. This product offers superior compressive strength, making it impact and chemical resistant, and resistant to environmental stress cracking.
Product Properties
The product is made of a 2-layer geocomposite. The first layer is a high-density polyethylene drainage core that serves to drain water quickly and freely to the footing perimeter drain, preventing any build-up of hydrostatic pressure against the waterproofing layer. It is extremely effective at protecting the waterproofing material during backfill operations.
The second layer is a heat-bonded PP geotextile that will not rot and absorbs water. It also prevents clogging of the flow passages in the drainage core.
How To Use This Product
You need to unroll the dimple board up against the foundation wall and is typically used in combination with liquid or sheet-applied waterproofing. Install the top edge of the drainboard at grade level. Take the bottom edge and place it close to the perimeter footing drain. There are also accessories are also available for easy fastening and termination details.
Case Study Project
The Audain Art Museum is the ultimate Canadian art museum housing eclectic art while the actual building is shaped like a hockey stick. Although they display art that people come from far and wide to view, it’s the unseen elements that truly make this building incredible. This private museum is 56,000 sq ft, sitting in the alpine forest of Whistler in British Columbia.
The exterior of the building is covered in a dark metal so it would blend in with the shadows of the forest and could handle a large load of snow that is typical for the area. According to the Architectural Institute of British Columbia, this restrained the form and character of the building while providing a quiet conservative backdrop for the art and surrounding landscape. If you look closely, you will see the building sits on 6 concrete piers. This was to ensure against flood conditions from the nearby creek. It almost appears as if the structure is floating among the trees while sitting a full story above the grade. Patkau Architects is a Vancouver-based firm that designed the building and given the job to create a high-performance building that would house precious artwork while blending into the natural surroundings of the forest.
While the project might have seemed simple enough, it was actually quite difficult due to the many angles and sloping walls with some slanting at 50 °. The metal covering also led to some challenges because of the ribbed pattern on the building’s exterior. The Audain Art Museum was designed to protect its content during its severe winters.
Patkau Architects decided on Delta®-Vent SA to provide the protection they were looking for. They also were given an air-tightness by the membrane which also helped to keep down energy costs. The adhesiveness of the membrane helped to improve the time needed for building by allowing the builders to construct the rood panels ahead of time in a modular format. As it was in a factory environment, it allowed the membrane to be installed in a controlled environment rather than something unpredictable. The panels could be easily transported to the site without risking the membrane blowing off. Due to the vapor absorption of Delta®, it allowed moisture within the building to escape through the membrane and thereby protecting the museum’s interior. The high characteristics of the product helped the museum to maintain a constant temperature and humidity level all year round to protect the artwork.
Continually working in the forest in a flood plain led to a unique configuration. According to John Patkau, without proper drainage, the building would be damaged and the artwork would be highly vulnerable to damage as well. A poorly installed waterproofing system could lead to hydrostatic pressure to build-up causing cracks in the foundation which would lead to the entrance of water. Patkau Architects needed to find a way to control the flow of below-grade water and direct it away from the load-bearing components of the building.
this product was chosen for the below-grade areas of the building. A drainage board was needed for high compressive strength, excellent drainage abilities, and exceptional long-term performance. They got what they needed the museum is completely solid with the artwork being constantly protected.
The Audain Art Museum is a true masterpiece unto itself. The general contractor, sub-trades, and architects that were involved in the construction received 4 awards during the 2016 28th Annual Vancouver Regional Construction Association. During the Annual Vancouver Regional Construction Association in 2017, Patkau Architects won the Lieutenant Governor of British Columbia Award in Architecture.
