Location
Elmbridge, Surrey
Sector
Residential
Sandy gravel drained well, so the drainage layout could be finalised.
Soakaways work here
All the testing was done in a single visit.
One site visit
01
The uncertainty
A private developer needed infiltration rates at the proposed drainage locations to satisfy SuDS requirements for a new-build residential scheme.
02
What we established
Sandy gravel strata gave favourable conditions for infiltration.
03
What changed
Completed in a single site visit and reported shortly after, allowing the design team to finalise the drainage layout and proceed with planning.
04
How we got there
- Machine-dug trial pits to the required depth with vertical sides and prepared bases
- BRE 365 testing using the three-fill-cycle method
- Full report with trial pit records, infiltration data and design input
