Can I lay my new paving stones over my existing concrete driveway and patio?

Architectural Block, Architectural Masonry Products, Masonry...
Yes, provided you have ample room to allow for the additional 3 inches that will be above the concrete. If this is going into a doorway, you may have a problem with clearance. Also, the concrete should be free of any major cracks. Remember, any movement in the concrete slabs that you are going over will show themselves in the surface of the paving stones.

Can I install brick over my existing concrete or asphalt driveway, patio or walk?

Master Masonry: Frequently Ask Questions
Paving can be installed over existing concrete or asphalt as long as it is in reasonably good shape. To ensure an adequate foundation for the brick, the existing concrete slab or asphalt should be inspected and repaired as necessary. Any cracks, chips, holes, dips or spalls should be repaired in order to achieve a flat surface. The brick can be installed either with or without mortar. If no mortar is used, a half-inch setting bed of coarse sand should be laid and compacted.

Stamped concrete is merely concrete slabs with a pattern stamped into the surface. They are susceptible to the same problems of a concrete slab sidewalk or patio.

Should I seal my concrete paving stones? Are there any advantages to doing this?

Architectural Block, Architectural Masonry Products, Masonry...
There are several advantages to sealing concrete paving stones. Sealing paving stones will help them to resist staining. Sealing will also help to bind the sand in place and prevent germination of weed seeds that may collect at the surface of joint sand. In New Jersey and New York, only water-based sealers are available. One disadvantage to sealing paving stones is that it would need to be sealed every couple of years, thus increasing the maintenance of the project.

Frequent Questions - Water Smart Landscapes
No. You can incorporate all of these into your landscape, but we will not include these areas in determining your incentive. We will subtract these nonpermeable areas from those that meet our conditions when determining your incentive. However, if the patio or walkway is brick or flagstone with sand grouting (not concrete) allowing air and water to pass through, these could be included in your conversion area, assuming all other program conditions are met.

Will weeds grow up from my paving stones?

Architectural Block, Architectural Masonry Products, Masonry...
The growth of weeds or grass results from seeds blowing into, and then lodging in the joint sand. Weeds do not grow up from the bottom through the quarry process. Controlling these weeds is a simple solution. Mix a pre-emergent weed killer into the joint sand. Should weeds germinate over time, the use of a post emergence weed killer, such as Round-up, can be spot sprayed to control the problem.

Jeepers Creepers - Frequently Asked Questions
By all means! Choose low-growing selections that are also rated medium or high for Foot Traffic. These plants will fill in the gaps between stones but still stay low enough to avoid tripping pathway users. Be aware, however, that plants do not give the same grip as stone, so pathways may become somewhat hazardous when wet. In regions with regular winter snow, plants can also interfere with snow removal or cause a buildup of ice.
