Wallbarn 3–8mm Adjustable PVC Wedge – Slope Correction & Membrane Protection for Paving Support Pads

The Wallbarn 3–8mm Adjustable PVC Wedge is a simple yet highly effective solution for compensating for falls on sloped roof decks during paving installations. Designed to be loose-laid beneath fixed height paving support pads, this wedge adjusts the angle at which the pads sit, ensuring a stable, level surface above.

Tapering from 8mm at its highest point to 3mm at the lowest, the wedge offers reliable slope correction while also acting as a shock absorber. It provides added membrane protection, particularly when used in combination with plastic paving pads in suspended slab systems.

Key Features of the Adjustable PVC Wedge

• Corrects Roof Falls: Designed to counteract the angle of sloping surfaces, allowing paving pads to sit flat and level.

• Tapered Profile: Measures 8mm at the high end, reducing to 3mm, for fine-tuned slope adjustment.

• Membrane Protection: Acts as a protective buffer between support pads and delicate waterproofing membranes.

• Shock Absorption: Reduces vibration and impact transfer through the system for added longevity and stability.

• Loose-Lay Installation: No fixings required – simply place beneath the pad as needed for quick on-site correction.
