Installed by experts.
DrainStar is designed to be used in combination with TUFF-N-DRI® products. Your Barrier Solutions Contractor has
the experience and extensive training to ensure the highest quality
application of DrainStar and the waterproofing product you prefer (see diagrams, far right).
Flow characteristics.
DrainStar provides a flow quotient of 170 gallons/min./ft. (when tested to ASTM
D4716-95 with hydraulic gradient of 1 with confining stress of 3600 PSF).
DrainStar offers a full array of fittings that make the system fast, easy and
versatile to install. End and side outlets are available for your choice of drainage
exits. And corners guard fittings are available to help DrainStar follow 90° angles
while maintaining water flow.
Backfill soil (1) typically contains many different particle sizes.
When the soil comes into contact with the DrainStar filter fabric (2), the
larger particles bridge the smaller particles to form a "filter cake" (3). The
filter cake helps block the encroachment of finer soil particles to prevent
clogging or blinding of the filter fabric for long-term filtration performance.
Replaces gravel and drain tile.
DrainStar is an effective replacement for traditional foundation drain tile and
gravel systems. In fact, no gravel is required when DrainStar is installed on the
footing next to a minimum 24-inch height of quality foundation drainage board.
With DrainStar, there's no more scheduling of gravel deliveries. No carrying
gravel in buckets or wheelbarrows. No gravel scattered around the jobsite to become
a nuisance. So you save time and aggravation.

Vertical DrainStar installation
(with TUFF-N-DRI system) |
Drain tile and gravel systems (top) have a water collection area of a
minimum 24 square inches per foot in length. By combining DrainStar (A)
with at least 24 inches of a quality foundation drainage board such as
WARM-N-DRI®(B), you'll match the water collection area of a drain tile
and gravel system. WARM-N-DRI board has over a 30-year track record
of below-ground drainage performance Depending on your application needs,
DrainStar may be installed in a vertical (middle) or L-shaped (bottom)
design.
