Used extensively in Scandinavia, the Blue Platon subfloor system protects floor coverings laid over concrete by providing an impermeable damp-proofing layer, while the air gap created by its patented dimple configuration allows the concrete floor to breathe. The concentric dimple design also provides shock cushioning and sound-deadening for hard-surface floors.
