Soil Classification & Infiltration Suitability

Soil Inputs

Classify soil to BS 5930 / BS EN ISO 14688 and assess infiltration SuDS suitability. Combine with BRE 365 Test Logger for field-measured infiltration rate.

Engineer's Notes Optional: included in PDF report

Method: Principal soil type from dominant fraction; BS 5930 / BS EN ISO 14688 naming with Atterberg plasticity. Infiltration suitability follows BRE 365 / CIRIA C753 guidance: K > 1×10⁻⁵ m/s + GW > 1 m from base = suitable.
