Special Products
Global Precast Coastal manufactures a wide range of specialized precast concrete products for infrastructure, public works, and urban development across Southern Africa. Our offerings include stormwater solutions, industrial and municipal components, public safety structures, and utility products—ranging from kerb inlets and trench covers to shelters, barriers, plinths, and T-wall panels—ensuring durable, efficient, and long-lasting performance.
Median Drains HD
Heavy-duty median drains are designed to handle higher volumes of water and withstand more traffic load. Typically used in areas with frequent heavy vehicle traffic or where the drainage system must endure significant stress.
Median Drains MD
Medium-duty median drains are designed for areas with moderate traffic and water flow. They are typically used in less demanding environments compared to heavy-duty drains, and offer sufficient strength and capacity for everyday road drainage needs without the need for the high load-bearing capacity of heavy-duty versions.
Median Drain Grids
Concrete median drain grid covers are designed to protect drainage channels in road medians and their design varies based on the load they need to withstand.
Heavy-duty covers are for areas with frequent heavy vehicle traffic, while medium-duty covers are suitable for areas with moderate traffic.
Cover Slabs
Global Precast Coastal produces a wide selection of precast concrete cover slabs suitable for various purposes.
We provide our customers with a comprehensive range of services, encompassing design, manufacturing and transportation.
Penstock Rings
Penstock rings, resembling compressed framed manhole chambers, are primarily used in the mining sector for slime dams and mine dumps. These rings, available in standard sizes of 525mm and 750mm align using male and female joints and are stacked to form chambers. As mining waste accumulates, additional rings are added to prevent slurry backflow, allowing denser solids to settle while excess water spills over into chambers for redirection to treatment plants. Although treated, the water remains unsuitable for drinking and is typically reused in mining operations.
Concrete Shelter
Reinforced concrete shelters are sturdy, durable structures designed to safely store equipment. Made with concrete reinforced by steel bars or mesh, these shelters provide strong protection against weather, theft and physical damage. They are often used for storing valuable or sensitive equipment in various industries, offering a secure, long-lasting solution.
Road Barriers
Concrete road barriers are robust, precast concrete structures used for safety and traffic control. They act as physical barriers to prevent vehicles from veering off the road, colliding with hazards, or entering opposing traffic lanes. These barriers are commonly seen on highways, construction sites and at events to separate traffic, protect pedestrians and secure perimeters.
Square Chambers
Square concrete chambers are precast concrete structures used in drainage and utility systems to provide access for inspection, maintenance, and repair.
Our standard sizes are:
• 2000 x 2000 x 500/1000 high
• 3000 x 2500 x 500 high
• 4000 x 2500 x 500 high
Various sizes and heights are available. Please contact your nearest sales agent for more information.
Pipe Culvert Wing Walls
Precast concrete wingwalls are structures designed to be installed at the ends of culvert pipes or box culverts to guide water flow, prevent erosion, and provide structural support for embankments.
They are typically used at the inlet and outlet of culverts to improve hydraulic efficiency and protect the surrounding area.
Prasa Walls
Our latest product range includes high-impact security walling to provide an extensive solution to improve security at rail corridors and substations. These heavy-duty units are made to offer secured protection against looting, theft, trespassing, and riots.
These walls come in precast bases, I-section columns and panels of 4m high and 5m long sections. This wall system has been used at several Prasa premises and we have the necessary approval by Prasa.
Specifications and more details are available upon request.
Eskom Walls
One of our offerings is the Eskom Security Wall, 2.4m in height with a thickness of 150 mm. This wall offers a sophisticated, high-strength concrete structure, ensuring exceptional security. Designed as a monolithic guardian, these walls are specifically engineered to offer formidable resistance against intrusion and to endure the severe tests imposed by environmental elements and potential breaches.
The choice of precast concrete for these security walls is not just about immediate needs; it’s about enduring security. When contrasted with alternative materials such as galvanized steel and brick walls, our concrete solutions stand out for their longevity, providing relentless security and unmatched durability.
The Eskom Security Walls are modular and designed with a robust base, ensuring an easy and straightforward setup without the need for on-site concrete work, thereby minimizing preparatory efforts. These security barriers are instrumental across South Africa, safeguarding assets in sectors like energy, government infrastructure, and commercial sites.
