Paver Installation FAQs
How strong are concrete pavers?
Concrete pavers are specified to strengths that are typically two to three times that of poured concrete, if installed properly. It’s not just the pavers that provide this strength, but also the correct depth of concrete base under the pavers.
What keeps the paver edges from moving?
Paver installation should start with the proper base material for the job. Crushed rock with approximately 1 1/2 inches of concrete or gunite sand is recommended. Installation of proper edge restraints is key to preventing spreading of pavers.
Are pavers hard to clean?
There are products available that are specifically made for cleaning pavers. You can use a pressure cleaner on pavers, but do not use more than 1,000 to 1,200 psi of pressure or you could cause damage to the paver surface. If you have serious stains such as tire marks, you should consider hiring a professional to clean your pavers.
Can concrete pavers be placed over concrete?
YES!! Concrete pavers can be placed on top of existing concrete when the surface is relatively flat, without large cracks, and when the elevation can be increased by 1–2 1/2 inches with no adverse effects. Edge restraints are used (sand, mortar, or glue). It is often better to remove the existing concrete and place the pavers conventionally. Contact your dealer for further considerations.
After you’re done paving the work surfaces, should it be sealed?
Sealing pavers is a personal choice. Sealing does, however, retard fading of paver color and provides a measure of protection from some stains. Before sealing, pavers must be clean and dry. Once sealed, you will need to re-seal approximately every two to three years.
What type of interlocking concrete paver is better?
There is very little difference between pavers in general. The qualities that make a paver a strong hardscape option include its compressive strength, water absorption rate, and abrasion index.
