Look Inside

 

 

Explore the world of drainage. It’s more interesting, and complex than you might think.  Without adequate drainage, the ground can erode, and soils can become waterlogged for extended periods damaging plants, buildings, roads and other infrastructure. Too much water in the wrong place can be a massive problem at the best of times; but with good planning and proper provision of drainage, that excessive water can be taken away faster, and damage minimise.

This book shows you how risks can be better considered and ways in which future issues can be mitigated.
