Glass Reinforced Polymer (GRP) is rapidly gaining recognition as a superior material in infrastructure projects, particularly as sacrificial formwork for bridge construction. Its exceptional durability and low maintenance requirements can contribute significantly to sustainability throughout a project’s lifecycle.
Companies such as Mekina Industries have pioneered the use of GRP in sacrificial formwork systems for reinforced concrete bridges, where the formwork remains in place permanently after the concrete cures. This innovative application eliminates the need to dismantle and dispose of traditional formwork, reducing waste and environmental impact. The lightweight nature of GRP simplifies transportation and installation, lowering energy consumption during the construction phase and further supporting eco-friendly practices.
One of GRP’s primary advantages is its resistance to environmental stressors. Unlike steel, which can corrode, or plywood and timber, which may rot, GRP is closed-cell and resists moisture ingress and corrosion. These properties ensure that GRP formwork supports the concrete’s curing process effectively and continues to play a role as the soffit of the underside of the bridge structure for decades to come.
The low maintenance requirements of GRP are another key benefit. Traditional formwork materials often necessitate costly and resource-intensive maintenance to prevent degradation. In contrast, GRP’s long-term durability reduces the need for repairs or replacements, minimising operational costs and associated carbon emissions.
But not all products are created equal. The unique design and manufacturing process of our Mek-Dek panels for GRP sacrificial formwork allows for precise, bespoke designs, enabling engineers to achieve complex geometries. This design flexibility not only enhances the aesthetic appeal of the structure but also ensures it meets specific functional requirements.
We are also unique in the market for being able to offer a recycling solution for any end of use or waste product – further strengthening our sustainability credentials. By choosing Mek-Dek for sacrificial or leave-in-place formwork in bridge construction, engineers and developers can deliver innovative, durable, and environmentally responsible infrastructure that stands the test of time.
