TerraDrain installed at Bletchingley
10 March 2020
Demco’s specialist track drainage pipe TerraDrain 11 has been installed as part of upgrade works at Bletchingley Tunnel in Surrey.
TerraDrain was used because it is approved for installation at shallow depths for high load track bed drainage. Designed to be installed as shallow as 300mm below sleeper, this heavy-duty HDPE pipe with its unique O-Ring push-fit joint system ensures rapid installation.
More than 300m of 315mm diameter TerraDrain 11 was installed in the 6ft in the Bletchingley Tunnel project last week, proving again it is the correct choice for track drainage.Download PDF
