In Ashford, we often see foundation designs that underestimate the variability of the Weald Clay. A proper soil mechanics study here has to account for the stiff, fissured clay that swells in winter and shrinks in summer. The Hythe Beds to the north add another layer of complexity with sandy layers and chert bands. Our laboratory handles both undisturbed and bulk samples from the Ashford area. We run classification and strength tests under BS 5930:2015 procedures. For projects near the Stour, soft alluvium requires in-situ permeability assessments before any earthworks. The data we produce is not generic; it is specific to the Ashford strata, which helps structural engineers refine bearing capacity and settlement calculations.
The fissures in the Ashford Weald Clay control the mass permeability more than the intact matrix does. Our tests quantify that.
