Area Drains and Planter Drains
When area deck or planter drains
penetrate concrete slabs above the ground floor, they need to be
waterproofed. ProSet has developed a very inexpensive, simple,
reliable and long-lasting system that provides for waterproofing as
well as the drainage receptor.
system is called ProSetís Tri-Level Drainage System. It
consists of ProSetís special cast-in-place coupling sleeve with a
flanged interceptor top that is used for attaching, to the drain
penetration, the waterproof membrane material that waterproofs the
floor. This allows the water runoff through the sub-grade area into
the drain itself through this special receptor. A perforated pipe,
which drains the residual level, attaches to the upper drain body
that drain the surface water. The way in which the drain is
installed is shown in the drawing, below.
The benefits include the
much lower cost and the ease of installation by simply setting an
adjustable sleeve coupling PVC fitting into the concrete pour. The
membrane is easy to attach to the receptor flange and there are a
variety of drain bodies and strainers available. A very important
benefit is that the assembly will never rust out and corrode like
the metallic penetration systems of the past.
