TwinWall Surface & Stormwater Drainage System
Product catalogue
TwinWall is a cost effective pipe system
intended for use as a direct alternative to
all non-pressurised gravity drain systems
other than where Local Authority adoption
is necessary. Smaller diameters are
manufactured from high density
polyethylene and larger diameters
manufactured from polypropylene.
Typical applications include highway filter
and carrier drains, rail track drainage, and
unadoptable surface water drains, for
example, on industrial or commercial
developments.
