Subsidence investigations & analysis

Cost-effective solutions to
help safeguard your property.

Subsidence can have a severe impact on buildings, often resulting in structural damage due to excessive foundation settlement. At A F Howland Associates, our decades of experience – particularly in the East Anglia region – enable us to identify causes and provide cost-effective solutions to help safeguard your property.

Our investigation methods

• Exploratory holes: cable percussion, window sampling, or trial pitting to identify underlying features and collect soil samples for analysis.
• Dynamic penetration testing: evaluates soil resistivity for an in-depth understanding of ground conditions.
• Foundation inspection pits: determines current foundation construction and depth.
• Structural & vegetation surveys: assesses the impact of nearby structures and foliage on soil moisture levels.
