Wallbarn Plastic Support Pad

Wallbarn 14mm & 17mm Plastic Support Pads (4mm Lugs) – Fixed Height Paving Spacers for Uniform Surface Drainage

Wallbarn’s fixed height plastic support pads offer a simple yet robust solution for cost-effective paving installations. Available in 14mm and 17mm thicknesses, these injection moulded HDPE rings feature integrated 4mm lugs to ensure uniform paving slab alignment and reliable surface drainage. Designed to be laid directly onto waterproofing systems, these pads are particularly well-suited for inverted roof build-ups, terraces, balconies, and podium decks.

The circular, hollow-centre design ensures rainwater is efficiently channelled below the paving surface, eliminating standing water and helping to protect the waterproof membrane beneath. Lightweight, durable, and made from recycled plastic, these support pads provide consistent, mess-free installation without the need for fixings, adhesives, or mortar.

Key Features of Wallbarn Plastic Support Pads

• Fixed Heights Available: Choose from 14mm or 17mm heights to suit your build-up and drainage requirements.

• 4mm Integrated Lugs: Ensure consistent 4mm spacing between paving slabs, providing precise alignment and water run-off gaps.

• Weatherproof & Durable: Made from injection moulded recycled HDPE, offering strength, flexibility, and cold resistance.

• Non-Invasive Installation: No mechanical fixings required – pads simply sit in place, preserving the integrity of the waterproofing membrane.

• Designed for Drainage: Built-in 8mm drainage channels and hollow core enable effective water flow beneath the slabs.

• Lightweight & Reusable: Easy to handle and reposition, making them ideal for fast-paced commercial or residential projects.

Ideal for Ballasted Inverted Roof Systems

These pads are perfect for supporting 20mm porcelain paving or concrete slabs in suspended applications. The weight of the slabs holds the system in place securely, removing the need for adhesives or structural bonding. This allows for simple future maintenance, reconfiguration, or inspection of the surface beneath.

For stretcher bond or large-format slabs, the positioning lugs can be removed to create a flat disc, offering additional centralised support where needed. Each pad can also be snapped into halves or quarters for edge or corner placement, ensuring a clean and professional finish without unnecessary waste.
