Slab Support – Deck & Landscaping Support Pad

Reliable slab support for dry (mortar-free) terrace and outdoor flooring installations. Designed to form a stable base for large-format stone or concrete slabs, this support pad creates a distance from the substrate while also providing separation between adjacent slabs. The smart cross-joint design allows frost-proof terrace installation and facilitates water drainage. By stacking up to three units, the support height can be increased in 10 mm increments for precise leveling.
