Apex was set up in 1992 to provide specialist drilling services to the South Wales coal industry and since then has rapidly grown and diversified to become one of the major drilling contractors in the UK. The management team and drill crews have a wealth of experience in all aspects of drilling and pride themselves in providing a professional, high quality and cost effective service. Unsurprisingly, the company still specialises in mineral exploration drilling and provides drilling advice and services to all of the major public and private coal prospecting and mining companies across the UK. Through careful strategic acquisitions, Apex now has one of the largest modern fleets of drilling rigs in the UK and has expanded to provide drilling services to site investigation, water well and geothermal (ground source) projects.

We are a specialist mine workings remediation contractor. We carry out the treatment of shallow mine workings, mine shafts and adits, by drilling and grouting. We also carry out exploratory rotary drilling to investigate for the presence of shallow coal seams and mine workings. We also undertake bulk void filling (eg sewers, culverts and the like).

Since 1985 LIM has been recognized internationally as a specialist in instrumentation and measurement, whether during or after drilling (drilling instrumentation and borehole logging). In terms of INSTRUMENTATION which is its core historical business, LIM SAS offers a wide range of data loggers whether for drilling parameters, in-situ geotechnical tests (Pressuremeter, Penetration tests, Lugeon packer tests) and special foundations processes such as low pressure grouting, jet grouting and bored piles. LIM SAS recently completed its range of data loggers with equipment allowing borehole deviation measurement and high precision GPS navigation (RTK) for drilling rigs. Thanks to its GEO-LOG 4 cloud based software, LIM offers a solution that automatically transfers and preprocesses data recorded on site. In terms of geophysical BOREHOLE LOGGING, LIM LOGGING, which is the result of the acquisition by LIM of Electromind in 2017, now offers a very complete range of logging probes. At the international reputation level, the OPTV and BHTV televiewers from LIM LOGGING are unanimously considered to be the benchmark products on the market.
