Our Drilling Services
HDD Africa is one of the market leaders in South Africa for Directional Drilling. The technology used allows for pipelines of almost any material, with diameters of up to 650mm and lengths to 350m to be installed in one single operation.
Why Directional Drilling?
- Directional Drilling overcomes the need for costly and inefficient trenching methods which have a huge impact on the environment and general traffic flow and also create massive amounts of waste materials that need to be disposed of,
- In just three simple steps, the drill rig performs a pilot bore, size ream and finally pulls in the pipe behind it,
- Minimal disruption to traffic, buildings, and other utilities,
- Avoids sizable surface damage and costly restoration required for old trenching method, this adds to installation cost due to more time taken to complete projects,
- Accelerated project completion timeline,
- Easy to set up and operate,
- Minimal crew size, and
- Our aim is to reduce your project cost, make you more competitive against your bidding competitors and speed up your projects
What We Do
Horizontal Directional Drilling (HDD)
Various Directional Drilling technologies are being used in all soil types as well as directional rock drilling.
Trenchless Soil Displacement (Moling)
Straight directional soil displacement via moling technique for distances up to 30m and sleeves ranging from 40mm – 130mm.
Pipe Ramming (Jacking)
Pipe ramming also refered to as pipe jacking is a trenchless method for installation of steel pipes and casings.
HDPE Pipe Jointing
A pipeline is only as strong as its weakest connection. When it comes to joining HDPE pipe, there are several common methods that are used, each with its advantages and disadvantages. At HDD Africa we use the following methods;
- Butt Welding,
- Electrofusion, and
- Flanced Connections.

Horizontal Directional Drilling -RIG
Directional Drilling, better known as Horizontal Directional Drilling (HDD), is one of the methods of trenchless technologies used by HDD Africa. Horizontal Directional Drilling is the best way of getting utilities / services from point A to point B without destroying or damaging the existing infrastructure or obstacles that are along the way of point A to point B. With the Directional Drilling capabilities of HDD Africa which goes above and beyond traditional trenching, we make connecting utilities and services in places that traditional trenching make impossible, possible.
Applications:
- Water Pipe lines,
- Fibre Infrastructure,
- Gas Distribution Networks,
- Underground Power Cables,
- Sewer Pipe lines,
- Pipeline Construction,
- Existing Pipe line upgrade and renewal,
- Wind Farm, and
- Other specific Applications.
Trenchless Soil Displacement (Moling)
Pneumatically driven earth-moving equipment work according to the soil displacement method. During propulsion of the probe, the soil is displaced into the surrounding soil and compacted. This creates an underground tube that can be used to first place a sleeve or in some cases the main service feed be it fibre conduits or water pipes etc.
