The Polyflow® Drainage family of products were designed and introduced by Polyguard Architectural Products to provide our customers a variety of solutions to lightweight drainage and at the same time be compatible with our engineered sheet and liquid membrane products. These products are lightweight, have high capacity, can decrease excavation needs and are easy to install.

We offer 5200, 15,000 and 21,000 psf products. Some of our products are to be installed vertically, some horizontally. Some products come with a high-strength Polymeric film on one side and some without.

Whether it is called “Drainage Board”, “Dimple Board”, or “Drainage Panel” we have below-grade drainage products, as well as a balcony deck drainage product to compliment your waterproofing system. For high volume applications see our Totalflow™ product and accessories.

Polyflow® BD

Polyflow® BD Protection and Drainage System is manufactured with a geo-composite of a formed pre-punched impermeable polymeric core covered on both sides with a non-woven filter fabric.

  • Drainage for balcony decks with less than 3” of concrete and foot traffic only.

Polyflow® 15 / 15P

Polyflow® 15 Drainage Mat is a two-part prefabricated geocomposite drain consisting of a formed polymeric core covered on one side with polymeric filter fabric. The fabric allows water to pass into the drain core while restricting the movement of soil particles which might clog the core. The core allows the water to flow to designated drainage exits. Polyflow® 15 is designed for vertical applications.

Polyflow® 15P has an additional built-in polymeric film to help protect your waterproofing and drainage layer.

  • Lightweight & Easy to Install
  • High Capacity flow; 4 times the capacity of aggregate or sand
  • Relieves Hydrostatic pressure
  • Compressive Strength: 15,000 psf

Polyflow® 18

Polyflow® 18 is specifically designed to handle the toughest of conditions. The 21,000 psf compressive strength allows this product to stand up to the stresses of a horizontal application. This product utilizes a woven filter fabric which is designed for concrete pours and has the strength to allow flow under loaded conditions.

  • Lightweight & Easy to install
  • Enhanced Compressive strength of core
  • Compressive Strength: 21,000 psf


Totalflow™ is a combination of our Polyguard sheet drain products with our unique Totalflow product.  In the Totalflow™ system, the sheet drain performs its normal function of water collection, while the Totalflow™ section provides both water collection and a high-profile section allowing for high-capacity water flow to designated drainage exits.

  • Fast and Easy to Install
  • Larger open area than perforated pipe
  • Accepts higher water flow from sheet drain and surrounding soil
  • Works well with Polyflow Sheet Dain Products.
