One of the key considerations for property developments in Limestone or Chalk environments is the presence of sub-surface solution features and voids.
The need to fully characterize unstable ground for foundation design is a significant factor for the valuation, construction and post-development phases. Solution features can be mapped using geophysical techniques by virtue of lithological contrasts between fill and surrounding geology, mass deficiencies due to voiding, or subtle effects on drainage.
Caverns and fissures within bedrock are often more difficult to target. Size and depth are important considerations when deciding on the most suitable geophysical technique.
