LT Omega Projects (Pty) Ltd offers a trenchless method called Moling, a technology widely used and ever increasing in the Civil engineering fields, that is used to lay pipes, ducts, and cables. We use a pneumatically driven machine or piercing tool known as a mole, which forces its way through the soil in line with the desired path of the pipe. This piercing tool creates the bore by compacting and displacing the soil rather than removing it. This trenchless method that we use avoids the need to dig trenches, therefore it has a very low operational cost. Moling is a method suitable for installing small diameter pipes, ducts and cables. General advantages of Moling are low operational and reinstatement cost, relative simplicity in operating, minimal or no excavation beyond the necessary connection pits or termination points for the installed product and minimal public disruption.
Our standard approach to Moling is digging a hole about 1m square and 2m deep and the hole will be small enough that we can dig it by hand instead of using a machine in inaccessible areas. Our team first surveys the bore path, surrounding area and launch or receive pits with suitable cable and pipe location tooling. All the survey drawings will be checked for buried utility positions. The pipes that we install are usually made of PVC, HDPE, or steel, depending on the tool size and soil condition, the maximum boring distance for non-steerable Moling is between 10 – 100metres or even longer, but the typical installation length is usually up to 10m in one run.
Benefits of Trenchless Moling includes
Moling technology is widely used and ever increasing in the civil engineering fields.
Compared to open trenching this method of underground installation and renewal of supply and disposal pipelines has major technical and economic advantages.
Shorter construction times is a major advantage; especially when providing property service connections like fibre installations or electrical cabling and when crossing busy roads.
Our team is well equipped with knowledge of the procedures that needs to be done when using this Trenchless method as well as the dimensions and safety points that should be considered
