Shaft sinking for manhole construction

The drainage division of TFGI was originally set up to compliment the domestic subsidence investigation side of our business following repeated requests from our client base of insurance companies and loss adjustor’s. However, since it’s formation it has developed as an entity in it’s own right. We now offer a full range of in-house drainage services from initial investigation through to remedial works and new installations.

The services we can provide include:

• CCTV drain surveys and reporting
• System tracing and mapping

• Excavations
• Shaft Sinking
• Manhole construction

TFGI launched it’s Geothermal drilling division in May 2007 to provide the emerging Ground Source Heat Pump (GSHP) industry with a professional drilling service utilising our combined knowledge of geology and drilling experience.

The most challenging part of a geothermal installation is the drilling. The UK is one of the most geologically varied places in the world. The completion of a successful installation relies upon the adoption of the most appropriate drilling technique as well as the use of the correct materials to ensure both the optimum performance of the system and the safeguarding of our environment.

TFGI only use high quality loop materials and thermally enhanced grouts.
