Slope Stability Assessment
In areas of historical and active slope instability, slope stability assessments are often required prior to development and are sometimes required to satisfy conditions imposed by the local authority and/ or warranty provider.
Ruddlesden geotechnical has particular expertise in the area of slope stability assessments, including the stability of existing slopes that may be built on or cut into, as well as the assessment of slopes that have recently or historically failed (landslips/ landslides).
Slope stability assessments will almost always initially comprise a desk study, of historical, geological and other information, and walkover survey, followed by an intrusive (borehole and/ or trial pit) investigation, with laboratory testing and monitoring.
Slope stability analyses are undertaken using specialist computer software.
If necessary, slope stabilisation recommendations are provided, which might include safe slope angles, drainage, reinforcement (e.g. soil nails or retaining structures), earthworks or toe weighting.
Slope stability assessments are also often required for conveyancing purposes.
