DrainMax™ soil strip drain is a two-part
prefabricated soil strip drain consisting of a
formed polystyrene core covered on all sides with
a nonwoven, needle-punched polypropylene 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
DrainMax™ soil strip drain is designed to
replace perforated pipe and stone drainage systems
in various applications. It provides a significantly
higher flow rate as well as increased ease of
handling and installation. The product can be
used alone or with other American Wick Drain products,
depending on the application.

Drain Attachment Methods:
When attachment to waterproofing material, concrete
or wood is necessary, several methods may be used
including metal stick pins, nails driven through
washers or wood lathing, construction adhesives
or double sided tape. Discuss materials compatibility
with waterproofing supplier before using adhesives.
Typically any method used for attaching waterproofing

Fittings are available to connect DrainMax™
to 4” pipe. These are available in several
configurations, depending on drain width and pipe
location. Details are available upon request.
Splices are available for 6” DrainMax™.
Other widths are spliced by peeling back the fabric
and interlocking the dimpled core. Afterwards,
replace the fabric and secure with tape.
Fittings are available for bending drain around
