About Us

We Are A Leading Company In The World

JDM Drilling’s projects in South Africa started in 2006 with extensive prior experience in the USA since 1997. The Head office is situated in Jeffreys Bay, although with substations in the Western Cape, Free State and Transkei, services can be done throughout the country.

The operators are well trained with a combined 50 years drilling experience. JDM Drilling constantly strives to deliver a high standard in our services of Trench less Technology, specialising in Big Bore pipelines (i.e. Sewer, Water and Storm Water provided) combined with Optic Fibre and Electrical sleeving.

JDM Butt and Fusion Welding division is one of the ONLY companies that do this specialized services in the Eastern and Southern Cape, Free State and Transkei.

WE SPECIALISE IN BIG BORE PIPELINES

HORIZONTAL DIRECTIONAL DRILLING

Mainly for the installation of underground utility pipes, ducts or cables in a straight or curved line without damaging the surface layers. HDD is a trenchless form of drilling that is faster, cleaner and more eco-friendly.

BUTT FUSION WELDING

Butt fusion welding is a thermo process of jointing HDPE or PP products to form a homogeneous fusion. The resultant joint is resistant to end thrust and performance under pressure is comparable to the pipe.

Pipe Bursting & Cracking

Pipe bursting, also known as pipe cracking, is a trenchless method used for replacing buried pipelines without the need for extensive excavation. It's often employed when traditional methods of pipeline replacement are impractical or too disruptive.

Transport

We offer transport services to the Citrus industry transporting citrus pulp & citrus waist, Agriculture industry transporting maize, wheat, barley, chicory and ect. and Construction/Civil industry transporting stone, sand and gravel.

HORIZONTAL DIRECTIONAL DRILLING SERVICES

Horizontal Directional Drilling (HDD), also known as directional boring or trenchless drilling, is a method used to install underground pipelines, conduits, or cables without the need for traditional trenching methods. It involves drilling a borehole along a predetermined path from the surface, and then pulling the desired utility through the drilled hole.

Horizontal Directional Drilling is commonly used for installing utilities such as water and sewer lines, telecommunications cables, electrical conduits, and gas pipelines. It has become a preferred method for many underground construction projects due to its efficiency, versatility, and minimal environmental impact.

Benefits

Minimal Surface Disturbance:
HDD minimizes disruption to surface infrastructure, landscaping, and traffic, making it ideal for urban areas, environmentally sensitive areas, or locations with existing utilities.

Reduced Environmental Impact:
By avoiding extensive excavation, HDD reduces soil disturbance and the risk of soil erosion or contamination.

Cost-Effectiveness:
While HDD may have higher upfront costs compared to trenching, it can be more cost-effective overall due to reduced restoration expenses and shorter project timelines.

Versatility:
HDD can be used to install various types of utilities, including pipelines, conduits, and cables, across different soil types and terrain features.

Here's how the process generally works:

01.

Planning

Engineers carefully plan the route for the borehole, taking into account factors such as soil conditions, existing utilities, and obstacles. The path typically follows a predetermined horizontal and vertical profile to reach the desired endpoint.

02.

Drilling

A drilling rig is set up at the starting point, which may be above ground or in an access pit. A drill stem with a drill bit is then inserted into the ground and directed along the planned path using guidance systems such as gyroscopic tools, magnetic guidance, or electronic tracking devices. As the drill progresses, it creates a pilot hole.

03.

Pilot Hole Enlargement

Once the pilot hole is drilled to the desired length, it is enlarged to accommodate the size of the utility being installed. This may involve using larger cutting tools or reaming equipment to widen the hole to the required diameter.

04.

Pullback

After the hole is enlarged, the utility, such as a pipeline or conduit, is attached to a pulling assembly and pulled back through the borehole to the starting point. This process can be done simultaneously with the drilling or as a separate step after the pilot hole is drilled.

05.

Connection and Restoration

Once the utility is pulled through the borehole, it is connected to the existing infrastructure at both ends. Access pits are backfilled, and any surface disturbances are repaired.

BUTT FUSION WELDING SERVICES

HDPE butt fusion welding is a method used to join two High-Density Polyethylene (HDPE) pipes together by melting the ends of the pipes and then pressing them together to form a permanent bond. This process is commonly used in the installation of HDPE pipelines for various applications such as water distribution, gas transmission, sewer systems, and industrial piping.

Overall, HDPE butt fusion welding is a reliable and efficient method for joining HDPE pipes, providing a durable and leak-free solution for various piping applications. Proper training, equipment, and adherence to industry standards are essential for ensuring the quality and integrity of fusion welds.

Benefits

Strong and Reliable Joints:
Butt fusion welding creates a seamless and
fully fused joint between the pipes, ensuring excellent strength and leak resistance.

Trenchless Installation:
HDPE butt fusion welding allows for the
installation of pipelines without the need for additional fittings or couplings, reducing the risk of potential leak points and enhancing the overall integrity of the pipeline.

Time and Cost Efficiency:
The butt fusion welding process is relatively
fast and straightforward, reducing installation time and labour costs compared to other joining methods.

Chemical and Corrosion Resistance:
HDPE pipes are highly resistant to
corrosion and chemical attack, making them suitable for a wide range of applications, including those involving aggressive or corrosive
environments.

How the HDPE butt fusion welding process typically works:

01.

Preparation

The ends of the HDPE pipes to be joined are cleaned and squared off to ensure proper alignment during the fusion process. Any dirt, debris, or contaminants are removed from the pipe ends.

02.

Heating

A specialized butt fusion welding machine is used to heat the ends of the HDPE pipes simultaneously. The heating element of the machine is placed between the ends of the pipes, and controlled heat is applied to melt the surfaces of the pipes.

03.

Joining

Once the ends of the pipes reach the appropriate melting temperature, the heating element is removed, and the molten pipe ends are quickly pressed together. This creates a fusion between the melted surfaces, forming a homogenous joint.

04.

Cooling and Solidification

After the pipes are joined, they are allowed to cool and solidify, creating a strong and durable bond between the two pipes. This cooling process typically takes a few minutes, depending on the size and thickness of the pipes.

05.

Quality Assurance

Various techniques such as visual inspection, pressure testing, or ultrasonic testing may be employed to ensure the integrity of the fusion joint and verify its strength and leak-tightness.

PIPE BURSTING / CRACKING

Pipe bursting, also known as pipe cracking, is a trenchless method used for replacing buried pipelines without the need for extensive excavation. It’s often employed when traditional methods of pipeline replacement are impractical or too disruptive.

Pipe bursting is commonly used for replacing various types of underground pipelines, including water, sewer, and gas lines. However, it may not be suitable for all situations, such as when existing pipe materials are unsuitable for bursting or when there are significant obstacles in the path of the new pipeline.

Benefits

Reduced Disruption:
Since it doesn’t require extensive trenching, pipe bursting minimizes disruption to surface infrastructure, traffic, and landscaping.

Faster Installation:
The process is generally quicker than traditional excavation, reducing the time required to complete the pipeline replacement.

Cost-Effectiveness:
While the initial equipment costs may be higher, pipe bursting can often be more cost-effective overall due to reduced labour and restoration expenses.

Minimal Environmental Impact:
Because it minimizes soil disturbance and surface disruption, pipe bursting is often considered more environmentally friendly than traditional excavation methods.

Here's how the process generally works:

01.

Preparation

First, access pits are dug at each end of the section of pipe to be replaced. These pits provide entry points for the equipment.

02.

Insertion of New Pipe

A specialized bursting head, attached to a hydraulic pulling machine, is inserted into the existing pipeline. This bursting head is larger than the diameter of the existing pipe and has cutting blades attached to its surface.

03.

Bursting

The bursting head is then pulled through the old pipe, breaking it apart as it progresses. This is typically achieved through hydraulic force exerted by the pulling machine.

04.

Simultaneous Installation of New Pipe

Behind the bursting head, a new pipe, typically made of high-density polyethylene (HDPE) or another suitable material, is simultaneously pulled into place. The bursting action effectively fragments the old pipe, making way for the new one.

05.

Connection and Restoration

Once the new pipe is in place, it is connected to the existing pipeline at both ends. Access pits are backfilled, and any surface disturbances are repaired.
