Terrafirma, an expert provider of environmental information and data intelligence, has become the first commercial organisation to be licensed by The Law Society as a ‘Report Producer’ of the official CON29M Report, a mandatory requirement for property and land purchase in coal mining areas. The Terrafirma CON29M Report offers property and legal professionals a level of interpretation, risk transfer and client protection not previously available and contains an expert professional opinion that is backed by comprehensive terms and conditions, with all liability for the outcomes of the report passing to Terrafirma, protecting the client, lender and solicitor.

SinkholeAlert: Demonstrating Disaster with Data

Exploring the themes behind Sinkholes in the UK

At Terrafirma, understanding the ground is what we do best: Our CEO Tom Backhouse was recently asked to feature in Channel 5’s documentary Sinkholes to provide an expert insight into the roots behind their cause. Inevitably then, when high profile sinkholes such as those at Fontmell Close, in St Albans or in Wednesbury, causing up to six million pounds of damage and evacuating families from their homes, we ask ourselves “can sinkholes be predicted?”.

Over the last few months and years, the experts at Terrafirma have meticulously observed, understood and recorded each sinkhole as they form. Now, armed with this information, Terrafirma is proud to present a new dataset and report feature; ‘SinkholeAlert’, allowing our team to examine the common themes behind these hidden dangers. 

Sinkholes: Explained

Delve behind the scenes of the Channel 5 documentary on Sinkholes.

The word sinkhole has become a term broadly used term to describe any hole in the ground created by erosional processes and the drainage of water. Ground hazards in the UK are often synonymous with the word sinkhole which can span from just a few feet in diameter to gigantic chasms large enough to swallow whole buildings.

They can have devastating consequences as can be seen on the new three-part Sinkhole documentary which began on Monday 20 November on Channel 5 and features extensive commentary from sinkhole expert and Terrafirma CEO and founder, Tom Backhouse.

Earlier today, Terrafirma's CEO and Founder, Tom Backhouse featured on the new series of the Rip Off Britain: Live Series on BBC One. Tom was invited on to offer advice to a frustrated home-owner who has fallen victim to her property being located close to an historical coal mine shaft, making it impossible to sell.

The property has seen its market value drop by £61,000 and despite being up for sale multiple times, it remained unsold earlier this year at a property auction in the West Midlands. 

The hidden risks the ground poses to farmers and landowners

Land. A word that is defined by its ownership, purpose, value or location and is often viewed, from a local, regional or national economic perspective, for its agricultural or development potential. However, land in the UK is also defined by our geological and extraction history, both of which can pose significant risks to property, investment and people. 

Protect Property with a Professional Opinion.

The age of solely relying on data in environmental risk assessment is over, with a visible shift in the way professionals perceive risks such as contaminated land and flood. Where historically data alone was enough to accept due diligence, now both a professional opinion and interpretative data modelling is a standard in assessing and managing these environmental hazards. 

However, despite the significant annual financial expenditure (between 4 and 15% of all Buildings Insurance Claims in the past 5 years were attributed to subsidence) and the increasing visibility of the ‘Sinkhole’ phenomena, this shift in due diligence process has not been replicated in assessing the risks the ground pose. 

 

Sinkhole appears in High Street Green, Hemel Hempstead

On May 2017, an 8-metre-deep sinkhole appeared on High Street Green, Hemel Hempstead, causing the road to be closed until around November. This is in the same neighbourhood (within 200 metres, or less than a 10-minute walk) from the 6-metre-deep sinkhole that opened up in Oatridge gardens in 2014, resulting in the evacuation of 17 people from their homes .  

Sinkhole caused by collapsed Chalk Mine at Pinner Wood School, Harrow, Greater London

A large sinkhole opened in the car park of Pinner Wood School, Harrow, forcing its immediate temporary closure. Geotechnical surveys and site investigations have been commissioned to determine the cause of the collapse and assess the stability of the land.

Coal mining and the need for interpretive analysis: A case study from Dudley, UK

Coal mining and the need for interpretive analysis: A case study from Dudley, UK

A sinkhole has formed during September 2015 on Bull Street, Lower Gornal Dudley, West Midlands. As a physical example of ground subsidence, the Bull Street Sinkhole (BSS) is hardly remarkable; with a diameter of >2ft and a depth of 6-9ft1, the BSS is a relic of historical mine workings, typical of those that form in the regions of the UK with a pronounced mining legacy.

In this instance, the degradation of historic shallow coal workings (the exploitation of coal seams at depths of <30m) triggered subsidence, though subsidence caused by the exploitation of a further 60 resources (tin, lead, copper, iron, sandstone, chalk and limestone just to name a few) is common across the UK.

Sinkhole at New Build Development, Plumstead, London

On the 2nd May 2016 a sinkhole believed to be 60ft deep and 16ft wide opened up on the doorstep of one of Skillcrown Homes new developments within Brickfield Cottages, Plumstead. The result of which led to the establishment of a 25m hazard zone and evacuation of 50 residents by the combined effort of the emergency services and Hexagon Housing, all of which were provided with assistance at a council run rest centre and overnight accommodation by the housing association. Following this, on the 3rd May evacuated residents were reportedly staying with families or in hotels whilst structural engineers looked to secure the site. The result of which, 30 households were returned to normality, whilst 10 awaited contact by Hexagon Housing. The remediation efforts, whether planned, completed or on-going are unknown.
