WHY SUBSIDENCE HERE?

This North Bristol suburb sits entirely on Mercia Mudstone clay, experiencing severe subsidence issues particularly during drought periods. The area's post-war housing boom used foundations inadequate for the highly reactive clay conditions.

Foundation damage in Patchway

GEOLOGY

Patchway is built on Mercia Mudstone throughout - a highly problematic Triassic clay that shrinks dramatically when dry. The formation here is particularly thick and pure, with active zones extending 3+ meters below surface affecting foundations to considerable depth.

COMMON ISSUES

1

Post-war housing estates showing major seasonal movement

2

1960s-1980s properties with strip foundations too shallow

3

Drought-induced cracking during hot, dry summers

4

Tree-related damage in established residential areas

LOCAL CHALLENGES

Patchway's proximity to Cribbs Causeway and aerospace employment meant rapid development. Many properties used minimal foundations - some only 0.9-1.0m deep, wholly inadequate for Mercia Mudstone. Mature tree planting now causes additional foundation stress as trees mature.
