Soakaway Testing

Fast, design-led soakaway testing to keep drainage design moving and programmes on track.

Supporting 250+ projects, clients and councils across the UK

01. Our Difference

Speed where it matters. Certainty where it counts.

Soakaway testing is rarely a box-ticking exercise. It sits directly on the critical path between planning, drainage design and technical approval.

Our service is built around one objective: getting reliable infiltration data into the hands of designers as quickly as possible.

By prioritising rapid mobilisation and high-speed reporting, we ensure your civil and drainage engineers have the reliable data they need to progress without the weeks of waiting that often stall project timelines.

Where infiltration results are marginal or ground conditions are complex, we provide technical input to help teams understand what the data actually means for layout, drainage strategy and construction.

04. The Detail

What is soakaway testing?

Soakaway testing, also known as infiltration testing, is undertaken to determine how quickly water can drain into the ground and whether infiltration drainage solutions are viable. 

Soakaway testing results provide the essential data needed to secure planning and technical approvals while informing drainage design and construction strategy.

Our reporting offers definitive clarity, confirming that infiltration will work as intended or identifying exactly what adjustments are required to your strategy to maintain project momentum.

What does soakaway testing typically include?

While scope is always tailored to each project, our testing packages provide a comprehensive data set to support your design team:
