Geoinvestigate’s experts have been providing specialist technical Coal Mining Risk Assessments for over 25 years to home-owners, house buyers, self-builders estate agents, developers, architects, engineers, Councils and the public. Our team can provide a top-quality, fast turn-around CMRA report within a week or less.
Geoinvestigate’s experts are highly experienced and fully qualified to carry out CMRAs. By doing it right the first time and complying with current government planning guidance we can save you TIME and MONEY by avoiding unnecessary delays caused by inadequate risk assessment.
- Planning applications in High-Risk former coal mining areas require a specialist Coal Mining Risk Assessment or CMRA. While some types of development may be exempt most new buildings and many building extensions are not.
- Geoinvestigate can help identify if your site falls within a High-Risk area and needs a CMRA or whether your development is exempt.
- The CMRA is a desk top study report based on a Coal Mining Report and other available maps, plans and information. No site visit is made.
- The CMRA report will identify the risks from coal mining and what needs to be done to make your site safe for development.
- Without a CMRA your planning application will not get approval and your development will be delayed.
- Our standard fee may be increased for larger or more complex sites.

Soakaway or percolation tests are used in the design of Sustainable Drainage Systems SuDS including soakaways, permeable paving and drainage fields.
Testing is carried out by falling head tests in a borehole according to BS 5930 or in a larger pit to BRE 365.
Geoinvestigate carry out a desk study assessment for every site to ensure the most appropriate test procedure and duration is proposed and this is reflected in our quote. It is not “one size fits all” when it comes to measuring permeability, and often a combination of methods is adopted to assess both near-surface and deeper soils.
“Percolation Testing” most often refers to Building Regulations Part H (or BS 6297). This is a shallow depth test carried out to determine a site’s suitability for shallow drainage fields serving septic tanks or package treatment plants. Here, soils must not be too permeable or too slow. If drainage is too slow a system will not function and cause flooding, but if drainage is too fast there is a risk of effluent affecting groundwater systems: there is a fine balance.
Geoinvestigate offer all of the above services, including soakaway design calculations and drainage field design, together with advice regarding the most feasible and effective SuDS options and combinations for any given development.
Services Included
Plate bearing, plate load testing or CBR testing simulates larger scale loading on engineered fills and cohesive and granular soils. The tests are used to establish the safe carrying load of piling mats, crane bases & outriggers and to check compaction and subgrade strength for road and pavement design.
Testing is carried out in accordance with BS 1377: Part 9: 1990. Kentledge is provided by-on site or hired-in construction plant 360 excavator, JCB 3CX or dumper.
Geoinvestigate provides national coverage with results issued at site or on the same day. Prices start from £450 + VAT excluding kentledge to be provided by the client.
