Infiltration tests

Is the architect designing a system to allow rainwater to infiltrate?  In that case, the architect would need information about how permeable the soil is.  An infiltration test provides the necessary insight.

Measuring permeability at different depths

​

We can measure the permeability of the soil at different depths. At each depth, a different technique is used.

 

  

• Surface measurement: double ring

• Up to 2.5 metres below ground level: Compact Constant Head Permeameter
