Can I Install Concrete Pavers over an existing concrete walkway or patio?
While this is not the preferred method, your installation can be laid over top of existing concrete walkways, providing there is not substantial heaving in the existing area. Several other issues need to be addressed. First, the grade will need to be reaised by about 3″ (the thickness of the pavers plus bedding sand or bonding agent). This is particularly critical if any doorways are involved. Second, remember that if the existing concrete slab should be reaised or drop with freeze/thaw conditions, the paver will do the talking. Q. What about stains on my installation or any areas that may become damaged. Stains can be removed with appropriate cleaning products. However, should a severe stain occur or some pieces become damaged, Concrete Pavers have distinct advantage. Individual Pavers can be removed and replaced in these situations. Remove the sand around the unit and use a “Paver Extractor” is also desiged for removing simple pieces.
