This document discusses the use of MiraDRAIN 5000, a drainage geocomposite system, in the Reconstruction & Improvement of Tuen Mun Road, Eastern Section project in Hong Kong. Over 80,000 square meters of MiraDRAIN 5000 was installed as slope drainage due to its thin profile of 10.2mm, which replaces 300mm of traditional granular filter and reduces installation time and costs. MiraDRAIN 5000 provides aggregate-free drainage and prevents soil infiltration through its dimpled core and filter fabric lamination.

CCW MiraDRAIN 5000, a drainage geocomposite system, has
been applied at the slope for drainage. More than 80,000m2 of
MiraDRIAN 5000 will be installed as slope drainage in this project.
By comparing the traditional granular filter, using MiraDRIAN 5000
can save a lot of time and labor cost during installation.
CCW MiraDRIAN 5000 provides an aggregate free drainage
system. Each panel consists of a uniquely molded
three-dimensional dimpled core formed out of high-impact
polystyrene. This high-strength, crush-resistant core is laminated to
filter fabric that prevents soil from entering the drainage channel
at both sides.
Seeking for thinner drainage layer is necessary in this project as
the slope area is very limited. The thickness of MiraDRIAN 5000 is
10.2mm, which can replace 300mm thick granular filter. In
addition, MiraDRIAN 5000 provide excellent water flow rate. Due to
its lightweight and ease installation, it can reduce the time of
installation.
