Median Drains
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.
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.
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
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.
Slabs
Global Precast produces a wide selection of precast concrete 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.
