Landrain Perforated Pipes
We stock 100mm perforated rolls of Landrain pipe, along with couplers and branches, ideal for creating efficient drainage fields.
​
Our coils of black 100mm perforated Landrain pipe are single-wall, corrugated pipes made from durable high-density polyethylene. Designed for fast and easy installation, these pipes ensure excellent water flow for effective drainage solutions.
​
Perforated Landrain pipes feature small holes along the pipe walls to collect surface water efficiently. In agriculture, they help improve field drainage and enhance soil quality. In construction, these pipes reduce flooding risks and relieve static loads on underground structures and retaining walls​
Soakaway Crates
StormCrate55 modular cellular soakaway crates are used in storm water retention, attenuation and infiltration applications.
The soakaway crates are designed to be easily stacked together to create a below ground storm water holding tank or to allow the infiltration of storm water into the ground around them. The void created by the crates can then fill up with storm water during heavy rainfall conditions. The collected storm water then drains away slowly into the drainage system when the crate is used for attenuation, or, soaks away slowly into ground water table when the crate is used for infiltration.
​
-
Load bearing strength of 562kN per m2
-
Designed for trafficked and untrafficked areas
-
95% void ratio
-
Integrated inlet and outlet
-
4 StormCrates per 1m³
-
Steadily disperse high intensity storm water by infiltration or attenuation. Each crate has a capacity of 237.5L or 0.2375m3
