| TUNNEL GROUTING |
| Over the last decade Sub-Technical has performed projects in active tunnel construction, we have worked with many of the J.V.'s and their associated engineering consultants. Our work has covered many of the common ailments such as ground and water control grouting, but has extended to include liner stabilization, preventing "overbreak" problems and gas control. Our range of materials coupled many processes adapted from our vast experience in the mining industry means that we provide innovative time saving processes to get driveages back in business quickly and effectively. |
