Necessity is mother of invention

Drainage is a major consideration in all highway and civil engineering projects. For surface water drainage there are many options utilising modern materials but for sub-surface drainage options are limited to traditional crushed stone filter drains, even though modern materials are available. Fildrain Geocomposite provides a sustainable alternative to crushed stone and this article explores the options, and attempts to explain the key criteria so that all highway engineers can have the confidence to utilise these new forms of sub-surface drainage.
