Key Benefits for Your Project
Strength You Can Trust
Our shuttering plywood is engineered to absorb the immense hydrostatic pressure of wet concrete during pouring. The cross-laminated softwood construction prevents blowouts and maintains shape – critical for large-scale commercial and infrastructure projects.
Save Time & Money
The smooth phenolic surface ensures easy form removal and reduces concrete surface defects. Less grinding, less patching, less finishing time. Plus, the durable WBP construction allows for multiple reuses across pours.
Custom Cutting Service
 Need exact dimensions? Our precision cutting service delivers sheets cut to your specifications – saving site time, reducing waste, and ensuring perfect fits for complex formwork designs.
Weather-Resistant Performance
WBP grading means our shuttering plywood performs in rain, humidity, and challenging site conditions. No delamination, no swelling, no compromised structural integrity.
FAQ's
What is shuttering plywood used for?
 Shuttering plywood creates temporary moulds (formwork) that hold wet concrete in place while it cures. It's essential for foundations, walls, columns, beams, slabs, and any cast concrete element. Also used for scaffolding platforms and temporary site structures.
Is shuttering plywood waterproof?
Shuttering plywood is WBP (Weather and Boil Proof) graded, which means it uses waterproof adhesives that won't break down when exposed to moisture during the concrete curing process or in damp conditions. However, it is not fully waterproof like marine plywood or phenolic film-faced plywood. For extended outdoor exposure or repeated wet-dry cycles, additional protection or sealing is recommended.
Can shuttering plywood be reused?
Absolutely. Quality shuttering plywood like ours can be reused for multiple concrete pours, depending on handling and site conditions. The WBP grade and phenolic surface extend service life significantly compared to standard plywood.
What's the difference between shuttering plywood and marine plywood?
Shuttering plywood uses softwood cores optimised for concrete pressure and cost-effectiveness. Marine plywood uses hardwood veneers for maximum moisture resistance in permanent water exposure. For formwork, shuttering plywood offers better value and performance.
What thickness of plywood is best for concrete formwork?
-
9mm-12mm: Light duty, small panels, curved formwork
-
18mm: Standard walls, columns, general formwork (most popular)
-
24mm: Heavy-duty foundations, beams, high-pressure applications
