Grillages are a framework made of single or double tiered beams that are laid crosswise, and used to stabilise foundations. They work especially well on ground that is soft or wet. Grillages are used to secure everything from road signs to telecommunication towers.
Using steel grillage rather than the available alternatives means that the installation can be completed quickly and conveniently. There is no need to pour concrete, which further simplifies installation. There are cost savings throughout the process due to fewer building materials, faster installation, and minimal disruption to transport. Surrounding infrastructure is also less disrupted, because we avoid the deep excavation that is necessary when foundations are created with concrete.
Screwfast has extensive experience in the design and installation of Steel Grillages. We have several standard grillage types that can be adapted to suit specific project requirements:
Bespoke grillages can also be designed. These foundations rigidly and securely connect the structure to the piles. A combination of fast installation and off-site fabrication makes this form of highly versatile connection an extremely popular alternative to the traditional method of using concrete to cap the piles.
Our Utility Grillages are manufactured to order in Cincinnati OH. Each part of these foundations undergoes a continuous, multi-step, quality control process including 3rd party inspections. With a highly skilled crews, manufacturing turnaround can meet tight deadlines.
Transmission projects are linear in nature, leading to changes in soil conditions. Every power line foundation presents a separate and unique challenge. Projects such as these provide the highest probability for contract overruns and change orders. This is because of unforeseen conditions during construction, including poor soils, water, or underground obstructions that can cause construction delays or reroutes.
