Kerb
Our precast kerbs are produced in accordance with municipal and highway standards.
Various figure types available upon request. Contact your nearest sales office to confirm figure types available in your area.
Kerb Inlets
Precast concrete Kerb Inlets are supplied to various municipal specifications:
• Tswane profile
• Pretoria profile
• Joburg straight
• Ekurhuleni Profile
They come in configurations of precast concrete channel (600mm lengths), steel angle-frames and concrete slabs, and can be supplied in any length of 600mm sections.
Grid Inlets
A “grid inlet with Mentis grating” refers to a stormwater drainage inlet where the grate covering the opening is made by the company Mentis, known for producing high-quality steel grating.
Grid Inlets are used in various industrial and construction applications; essentially, it’s a drainage grid with a Mentis brand grating on top to allow water to flow in while filtering out debris.
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 Grid
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.
Trench Covers
Precast concrete trench covers are designed to protect electric conduits and cabling.
Covering these is vital for pedestrian protection as well as to shield the cables from traffic.
Various sizes available upon request. Our trench covers comply with Eskom standards.
Cover Slabs
Global Precast 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, transportation, and installation.
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 or custom sizes, 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.
Wash Trough Small
The smaller wash trough is tough and durable and ideally suited outside as wash basins.
Constructed from high-quality concrete for durability and easy to clean and maintain. Excluding waste and trap.
Wash Trough Large
The larger wash trough includes pedestals and is tough and durable and ideally suited outside for both residential and commercial purposes.
Constructed from high-quality concrete for durability and easy to clean and maintain. Excluding waste and trap.
Pipe Plinths
A precast concrete pipe plinth is a prefabricated concrete base designed to support and stabilize various types of equipment, including precast concrete pipes, mini-substations, electrical cabinets, and more. These plinths provide a stable, level platform for equipment installation and offer features like anchoring points for secure attachment.
Carport Plinths
Precast concrete carport plinths used as solar panel bases provide the essential support and stability needed for efficient and long-lasting solar installations, making them a key component in the renewable energy landscape.
Available in a range of different sizes, Gobal Precast manufactures solar panel blocks, which can also be built to your exact requirements. Designed with cast-in lifting points for ease of handling, the blocks can be relocated if required and will outlive the lifespan of the panels themselves.
Water Meter / Hydrant Box
Precast concrete meter and hydrant valve boxes are enclosures typically made of reinforced concrete, used to house and protect water meters and hydrant valves underground.
These boxes are designed to be durable and provide easy access for maintenance and operation of the water infrastructure.
Pavers
Precast block pavers are versatile, durable, and aesthetically pleasing paving options made from concrete. They are manufactured in various shapes, sizes, colors, and textures, allowing for a wide range of design possibilities in outdoor spaces.
Precast concrete pavers are commonly used for driveways, patios, walkways, and other hardscaping projects, offering a cost-effective and customizable alternative to natural stone or brick.
Various Markers
Precast concrete markers are used to indicate the location of underground utilities like pipelines and electrical cables. They are typically made of concrete and can be customized with various markings, such as text or symbols, to identify the specific utility.
Precast road markers, like kerbs and traffic islands, are also used to delineate roadways, guide traffic, and provide pedestrian safety.
Bollards
Precast concrete bollards are durable, short vertical posts designed for traffic control, perimeter security, and pedestrian safety.
They effectively prevent vehicle intrusion into restricted areas while enhancing overall safety.
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.
Bus Shelters
Precast concrete bus shelters are durable, low-maintenance structures that protect waiting passengers from the elements.
Factory-made and easily installed on-site, they often include seating and can be customized with lighting, signage, or advertising panels.
Dogbones
A popular Grid Cover is the so called “Dog Bone” trench cover. It is a rectangular cover with narrowing on either long side towards the middle. When laid side-by-side the narrowing’s form slits through which the water can flow.
Custom made Precast Concrete Heavy Duty Dog Bone for Storm Water Grid Inlet where you require a road crossing.
Stock & Horse Trough
Precast concrete stock and horse troughs are durable, long-lasting water reservoirs designed for livestock, often made with reinforced concrete for strength and longevity.
They are available in various sizes and shapes to suit different needs and animal types, with features like rounded corners for safety, and options for drainage and water access.
Down Chutes
Precast concrete down chutes are prefabricated concrete components designed to safely and efficiently channel water or materials, like refuse, from higher to lower elevations.
They are commonly used in stormwater management, erosion control, and refuse disposal systems.
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.
