Are outdoor rubber tiles frost-resistant and suitable for use throughout the winter?
Outdoor rubber tiles made from polyurethane-bound rubber granules are frost-resistant and suitable for use throughout the winter. Their porous structure absorbs precipitation and allows it to pass downwards; water remaining in the pores has space to expand when it freezes, while the rubber granules and polyurethane binder remain elastic at sub-zero temperatures. The sub-base must also be constructed to withstand frost.
On bound sub-bases, water flows beneath and between the tiles in the direction of the fall towards the drainage system. On chippings or crushed stone, it drains vertically through the construction. If water collects beneath the tiles, a frost-susceptible sub-base may rise and then settle again after thawing. The tiles themselves remain unaffected, but the surface may become more uneven.
For winter maintenance, use a snow shovel with a smooth edge and avoid catching the tile edges. Salt used in normal quantities to melt ice does not harm the rubber granules.
