Professional soakaway testing (BRE365) to assess soil infiltration rates and design compliant, efficient drainage systems across the UK. Fast, accurate results with full reporting and expert guidance.
Our Soakaway Testing service, also known as a BRE365 Percolation Test, determines how quickly water drains through the soil to assess whether your site is suitable for a soakaway or sustainable drainage system (SuDS).
Percolation Tests
At Ground Force Group, we handle the full process from site preparation and testing to data analysis and reporting.
Our Soakaway Testing service, also known as a BRE365 Percolation Test, determines how quickly water drains through the soil to assess whether your site is suitable for a soakaway or sustainable drainage system (SuDS).
This test is a crucial step in achieving compliance with Building Regulations Part H and BRE Digest 365. It ensures your drainage design is efficient, environmentally sound, and approved by local authorities.

When should I arrange a soakaway test?
It’s best to carry out soakaway testing before finalising drainage or starting construction.
What is a soakaway test and why is it needed?
A soakaway test measures how quickly water infiltrates the ground. It’s required to design soakaways and sustainable drainage systems (SuDS) that comply with BRE Digest 365 and Building Regulations Part H, ensuring proper surface water management.
Most soakaway tests can be completed in a single day, depending on ground conditions and site accessibility. The full report is usually delivered within 48 hours after testing.
