How to maintain plastic paving grids over winter?
Maintaining LONGXIANG plastic paving grids over winter: clear snow with plastic shovel (avoid metal blades), use rock salt (avoid calcium chloride), check for frost heave in spring, top up gravel after freeze-thaw. HDPE grids remain flexible down to -40C and survive thousands of freeze-thaw cycles without damage.
Winter Tips
Snow Removal
Use plastic shovel or snow blower. LONGXIANG grids withstand snow plow blades at raised height.
De-Icing
Rock salt (NaCl) is safe. Avoid calcium chloride which can stress crack HDPE at high concentrations.
Spring Check
Inspect for settled areas, top up gravel, re-compact. LONGXIANG grids self-level after minor frost heave.
