Perforated pipe

Our soakaways are fabricated from perforated corrugated pipe produced from pre-galvanised steel coil, similar to helibore pipe. Unlike some forms of soakaway, our water drainage pipes are always fully accessible for inspection and maintenance

Manufacturing perforated drainage pipe in diameters from 0.3m to 3.6m to fit any situation, we can produce pipe systems or vertical rings or a combination of the two. We can also provide a full design and detailing service, consistent with SUDS, using the latest software.

We can determine the suitability and performance of a soakaway or infiltration system according to three criteria:
  • the capacity of the soil to infiltrate water - the "infiltration coefficient"
  • existing or historic groundwater levels - should be at least 1m below the invert of the intended soakaway
  • the plan area available for siting the soakaway unit
