Flat Base Concrete Mesh Spacers - Heavy Duty Grade Plate Chair Spacers for Rebar & Reinforcement - Dual Height - Membrane Safe Foundation Supports (40-50mm, 100, Piece)

• Membrane-Safe Design: The wide flat base prevents the spacer from puncturing your Damp Proof Membrane (DPM). Essential for maintaining the watertight integrity of your foundations and floor slabs.
• Anti-Sink Stability: Unlike "A-frame" or pointed spacers, these grade plates won't sink into sand, crushed stone, or soft soil, ensuring your mesh stays at the specified height for a perfect pour.
• Dual-Height Functionality: Each spacer offers two different cover depths (e.g., 40mm and 50mm). Simply flip or adjust the mesh position to reach your required specification without needing multiple products.
• High Load Capacity: Manufactured from heavy-duty, reinforced polypropylene, these spacers are engineered to support heavy steel mesh and rebar—plus the weight of workers walking on the mesh.
• Superior Concrete Flow: The open-frame design allows concrete to flow freely through the spacer, eliminating voids and air pockets while ensuring a complete bond with the reinforcement steel.
• Versatile Application: The universal cradle design fits a wide range of rebar and mesh diameters, making them the "go-to" choice for foundations, driveways, patios, and commercial floor slabs.

Achieve professional-grade concrete reinforcement with our Flat Base Grade Plate Spacers. Designed specifically for ground-level slabs, these spacers provide the stable support your steel mesh needs to remain at the correct depth during a pour. The wide, flat base is a critical safety and quality feature, preventing the spacer from sinking into soft sub-grades or damaging damp-proof membranes (DPM).
