3rd September 2019

Eric Zon, Lankelma Managing Director. Meeting the challenges of nearshore geotechnical investigations requires specialist input, not simply a transfer of land-based techniques to the marine environment. Like any engineering project, those being built in nearshore environments (in water depths of less than 20m) – such as ports, pipelines, cables and coastal defences – rely on […]

Our rapid turnaround of test results gave engineers from consultant Hydrock more time to analyse data on a recent investigation in Coton Park in Rugby. Our tracked rig UK2 carried out 28 piezocone CPTs to a maximum depth of 20m through clays and silts that became very stiff at depth. Hydrock’s Ciaran Davis said: “We were very pleased with how Lankelma communicated […]

Our steam-pressured decontamination system for cleaning rods before they re-enter the truck kept our site team safe from potential harm on a recent project for Golder Associates in Tavaux, France. After a rapid mobilisation of our track-truck UK3 from the UK, we carried out seven piezocone CPTs, to between 20m and 30m depth, through chemical tailings at an industrial waste storage facility. We also carried […]

Minicrawler ingenuity in south west quarry

Minicrawler ingenuity in south west quarry

3rd June 2019

Our team came up with an ingenious, and sustainable, way of coping with a stiff clay layer when testing an embankment in a quarry in the south west. As well as following the normal procedure of using screw anchors to fix the minicrawler rig to the ground, we fitted a frame either side of the rig allowing two tonnes of quarry sand […]
