Description

Reviews

In order to design a Drainage Field or drainage mound soakaway the ground conditions must be known.

Specifically, the percolation rate must be determined using the method defined in the Approved Document H. This rate is used to determine the dimensions of the drainage field soakaway.

This service requires the customer to complete the test and record the results in line with our supplied instructions.

The output is a pdf report of the results and calculation providing the infiltration rate required for the drainage field calculation.

Once the percolation rate has been determined the drainage field sizing calculation can be pursued and is available here.

Soakaways are appropriate for free draining ground material. If the ground is silty/clayey and a soakaway is still preferred please get in touch so we may understand your requirements.
