St Alban's Sinkhole: Part 2 - Terrafirma explore the possible causes of the recent #StAlbans #Sinkhole for a recent @BBC3CR #Radio #Interview.

An Innovation in Cornish Property Risk Assessment

Terrafirma collaborates with Cornish Mining Experts to bring new Ground Report to the South West

Cornish mining expert, Cornwall Consultants and national mining and ground report specialist, Terrafirma, have announced a collaboration that sees the launch of a new Ground Report combining leading digital mapping and data analysis with ‘on-the-ground’ experience and expertise to bring clarity to the current confusion among property buyers across Devon and Cornwall caused by the disparate mix of products available to them.

The Ground Report from Cornwall Consultants will see customers benefit from the widest range of the latest ground stability information relating to coal and non-coal mining, natural ground issues and even fracking combined with a vast mining archive and wealth of experience working in the region. The Ground Report includes an expert professional opinion, risk assessment and risk transfer and satisfies new Mining and Ground Perils guidance in the Law Society Conveyancing Handbook.

Shaft swallows car park in St. Ives, Cornwall

Late on Saturday 28th April, a 40ft deep and 3ft wide hole opened in a car park in Garth-An-Creet, St. Ives, Cornwall. Local emergency services were called to assess the scene and undertake work to prevent the hole from widening and affecting nearby properties. Subsequent investigation by Terrafirma concludes the hole was created by the collapse of a disused mine shaft.

Analysis of the Harrington Sinkhole, Cumbria

On the 4th January 2018, a 1.2m deep, 0.6m wide ‘’sinkhole’’ opened next to the Whitehaven – Workington railway line, near the coastal village of Harrington in Cumbria. For fears of the hole expanding and damaging the rail line, services were delayed in order to complete emergency repairs and infill the void. Initial observations have led rail engineers to speculate that a collapsed drain or coastal erosion accelerated by Storm Eleanor are the cause of the collapse. However, the correlation with known mine entries and collapses along the railway line have prompted Terrafirma to research further to see if past coal extraction may in fact be the cause.
