The most comprehensive ground risks and
liabilities report on the market.

Mirrored Ground Report

The Terrafirma Ground Report is a best-in-class ground risks and liabilities report designed to enable property professionals to better identify, manage and resolve ground hazards.

It identifies and interprets the risk to property from all man-made and natural ground hazards, providing your client with all the information about potential exposure of the property to ground risk.

Man-made hazards related to the UK’s extensive and varied mining heritage can pose significant risk to property, with the potential to cause subsidence and in extreme cases, collapse.

As standard, Terrafirma’s Ground Report includes an official CON29M and integrated Mine Entry Interpretive Report where applicable, saving your client approximately £150 when a Coal Mine Entry is identified within 20 metres of the property and speeding up the property transaction.

The UK’s history of mineral extraction goes far beyond coal, and the risk from historic mining and extraction of metalliferous minerals, limestone, chalk, gypsum, clay and brine, to name just a few, are also considered by the Ground Report, ensuring your client’s potential exposure to all mining related risk is thoroughly assessed.

Importantly, the Ground Report also considers risk from natural hazards like clay-related subsidence, landslip, natural sinkholes, and radon exposure which all have the potential to expose your client to physical property damage, emotional stress and financial loss.

Protect your client’s investment with certainty over ground hazard risk, based on the best available ground data and interpretation by Terrafirma’s team of geologists who, through years of training and experience, are best placed to understand the ground.

Dynamic next steps and an industry leading professional opinion ensure the purchaser, conveyancer and lender are all fully informed and report terms and conditions containing £10 million Professional Indemnity cover per report ensures any risks are comprehensively transferred from the conveyancer to the experts at Terrafirma.
