Can a damaged slab or paving stone be replaced?

Yes, provided you kept a few extra units during the initial installation (which is why we recommend buying about 10% more than the quantity needed for your project). To replace the slab or paver, scrape off the polymeric sand and, using two flathead screwdrivers, remove the old product and replace it with the new one. Fill the joint with polymeric sand and follow the manufacturer's instructions.
