Impermeable Area Surveys

Return to services list

We carry out Impermeable Area Surveys to determine where rainwater and surface water "run off" drain to.

A designated percentage of roofs, paved areas and highway are looked at and investigated for the client.

Dye testing is used to determine and prove all connectivity with the results being mapped out on site using a colour co-ordinated system.

The information obtained is then processed in mapinfo format with all colour coding and hatching to national standards.
