How does Assure work?

TerraSearch® Assure is designed to support due diligence risk management for the property and legal sector by packaging data and interpretation to provide a professional certification that expertly locates the risk to a site from all mining hazards associated with the UK’s mineral extraction legacy.

What does Assure reveal?

The unique TerraSearch platform is a tool that enables property professionals to locate potential mining and ground hazards within a residential or commercial site. TerraSearch instantly screens the risk from all UK past and present mineral extraction, including over 60 mining hazards such as coal, brine, tin, stone, gypsum, lead, limestone, iron, clay and many more.

TerraSearch Assure is required where the site is identified to be outside the Terrafirma Hazard zones, satisfying lender compliance and offering complete protection from past underground mining through a built-in £10 million bespoke Professional Indemnity Cover protecting all parties within a property transaction.
