We recently undertook a ground investigation near Marlow, Buckinghamshire along the southern edge of the Chiltern Hills. A Phase I and Phase II Investigation was required for a proposed commercial site on undeveloped land. The Phase I Desk study indicated the site is underlain by the Clay-with-Flints Formation (a chalk residual deposit) overlying the Newhaven Chalk Formation (formerly the Upper Chalk). For areas where chalk bedrock is underlying the surface there is a possibility of a...

Here at Geo-Integrity we can undertake assessment of the stability of both existing slopes and man-made cuttings or embankments. Many of our clients projects include the creation of entirely new slope profiles through imported soil earthwork embankments and/or steepening of existing slopes though cuttings. We recently undertook a project in Bedfordshire, on West Melbury Marly Chalk, where we were asked to check stability on designed slopes across the site. Using laboratory testing on collected...

We had to carry out Phase 3 supplementary site investigation on a site near the Buckinghamshire/ Northamptonshire border this month. We had previously undertaken a Phase 1 Desk Study and Phase 2 Ground Investigation for a proposed residential site. The investigation incorporated continuous tube boreholes to 6 metres with SPT testing, in-situ plate bearing testing for CBR values and modulus of sub-grade reaction, trial pits for soil description and contaminated land testing and some shallow...

We have recently undertaken remediation verification sampling at a site near the A5 on the Leicestershire/Northamptonshire border, located between Rugby, Leicester and Northampton. As part of the Local Planning Authority permission there had been a pre-commencement condition requiring a contaminated land site investigation and risk assessment. This was to be undertaken in accordance with the standards of DEFRA’s and the Environment Agency’s Model Procedures for the Management of...

Here at Geo-Integrity Ltd. we recently undertook a Phase I Desk Study at Anderton, located north-west of Northwich in the county of Cheshire. The Northwich area is well known for its extraction of salt since the Roman times. The salt in question belongs to the Northwich Halite Member which was deposited 220 million years ago during the Triassic Period. Similar to chalk, evaporates (natural salt deposits) are prone to both natural and artificial dissolution producing karstic landforms and...

We have recently undertaken a combination of modular window-sample boreholes, dynamic probing at a beachfront landslip in Weymouth in Dorset. The south coast and in particular the Jurassic coastline present many geotechnical hazards when undertaking a ground investigation, due to the wide variety of interbedded soils and rock encountered. Modern drilling techniques such as modular borehole rigs, allowed us to undertake testing along an active land slip, in extremely uneven and steep terrain...

We have recently completed a job, near Matlock in the Derbyshire Dales, where we were asked to provide a ground profile and soil & rock properties for a large retaining wall design in a farmyard. The decision to use sonic drilling techniques proved to be the way forward..

RPS 211 (or regulatory position statement 211) has applied to businesses who deal with excavated waste from unplanned utilities installation and repair works, but it is being withdrawn next year on 30th April 2020. The document has allowed companies producing a small amount of waste (<10m3) from the above activities to dispose of that waste as non-hazardous by default, without having to test and classify it beforehand. The kinds of waste types that have been covered include (but are not...
