Civilcast supply a range of precast concrete pit risers suitable for use in areas subject to wheel loads up to Class D. Our concrete pit risers are made to increase the depth of a stormwater and gully pit. This grants greater flexibility in meeting drain pipe depth requirements, so you can avoid excavation or damage to existing infrastructure. Pit risers are available in a range of sizes to suit the standard pit bases, and are used to easily extend the height of a standard pit.
