Our Horizontal Directional Drilling (HDD) capabilities include a range of HDD equipment to cater for small tight access bores, mid-sized bores and large diameter rock bores that has minimum disturbance to the ground surface.

Case Boring

Horizontal cased auger boring is the most practical solution for installation of pipe casings under roads, creeks, railways, buildings and almost anywhere that an open excavation is not an option.

Pipe Jacking

Pipe Jacking is an effective method of installing service pipes underground. Codmah's pipe jacking uses two methods - direct drive or a combination of casing and pipe jack.

We provide a full range of civil engineering services in the construction of gas, water, electrical, sewer and telecommunication infrastructure. Codmah establishes collaborative relationships with our clients and stakeholders to plan, manage and deliver quality civil projects.
