In some circumstances where there are safety or environmental concerns, or where limited disruption is required, G.P. Friel Ltd are able to offer clients trenchless solutions.
We have extensive experience in the following areas:
- Pipe ramming: Horizontal and vertical ramming of casings through various soil conditions.
- Pipe bursting: The replacement of existing pipelines by fracturing and displacing the host pipe into the surrounding soil. A new HDPE pipeline is inserted during this process.
- Patch liner: We offer a no dig repair system for pipelines, rehabilitation for installing a structural repair on cracked pipes and joint sealing.
- Slip lining: Inserting a smaller diameter pipeline into the host pipe. The annular space is then filled with grout.
Directional drilling: We use directional drilling to minimise disruption when required
