Frequently Asked Questions
Pavers
Q: Can I shovel, use a snow blower or snow plow a paver driveway?
A: Yes. With a properly installed paver driveway you can easily remove snow by any of these methods.
Q: What is paver interlock?
A: It is the inability of the paver to move independently of the paver next to it. It’s the locking of the pavers that cause loads to be spread over a wider area where the load is applied. It’s the key to the strength of the pavement system.
Q: Can I seal concrete pavers?
A: Sealing is not essential with pavers, however, liquid sealers are available as an option to help make spills and stains easier to remove. Liquid sealers are applied after the pavers are installed and are cleaned. The sealer soaks into the concrete pavers and into the sand joints, which helps keep the joint sand in place.
Q: How can I prevent weed and ants coming through my pavers?
A: joint stabilization sealer can be applied or polymeric sand can be used in the joints instead of coarse washed sand. Polymeric sand is brushed into the joints between the pavers, then a light mist of water is sprayed over the pavers. The water activates the polymers that bind the grains of sand together creating a solid yet flexible joint. Polymeric sand will not wash out of joints and will maintain its bond season after season even in our harsh climate.
Q: How do I remove stains and fix damaged pavers?
A: If the stain is on one or a few pavers, replacing them with new paver is the easiest. Depending on the style of paver some can simply be flipped over. Another option is to use a cleaner specially made for removing stains and for overall surface cleaning.
Q: What is efflorescence and can it be removed?
A: Efflorescence will eventually disappear. Over time, rainwater can wash and wear it away or when the supply of calcium hydroxide is exhausted. Typically, efflorescence will stop developing in approximately 18-24 months. There are commercially available cleaners that may be used. Follow manufacturer’s instructions.
Q: What makes pavers an ideal pavement?
A: pavers are ideal for freeze/thaw environments. Proper installation results in a pavement that is rigid, yet flexible. The joints between the pavers allow the walkway, driveway, patio etc. to move without cracking. Unlike asphalt, pavers are virtually maintenance-free. By definition, concrete pavers have a minimum compressive strength of 8,000psi (about 3 times stronger than regular poured concrete) and a maximum water absorption rate of 5%.
Walls
Q: What type of footing is required for wall systems?
A: A compacted stone base is required for all segmental retaining walls. This can vary in thickness and depends on the height of the wall and product being used. Follow manufacturer guidelines or consult with a contractor or engineer.
Q: How do I adhere caps?
A: Use a high strength, flexible concrete adhesive, to affix your wall cap.
Q: When should I have an engineer design my wall?
A: We recommend the use of a professional engineer on projects with wall height 4’ or higher or site with unusual site conditions.
