Self-Realization PaveDrain Case Study
Whitson CM
reconstructed a parking
lot to address drainage
and flooding of a historic
preservation site. The
design dictated a trench
drain to reduce sheet
flows from about 1 acre.
In lieu of a $27,000 trench
drain, we replaced
it with a $7,000 PaveDrain
drainage trench.
We excavated a 3ft trench
sloped at 2%; lined the
trench with an
impermeable
liner; placed 2 – 6in
perforated pipes on the
bottom of the trench;
filled with 3/4in crushed
rock; & placed PaveDrain.
AND,
unlike other paving
systems, no concrete
curbs or stem walls are
needed to
separate the blocks from
the AC pavement.
