Paver MaintenanceHow long do I need to wait before I clean and seal my pavers?
As a rule of thumb we suggest waiting 3-6 months. This allows most efflorescence to come out and weather away naturally. The real test is a visual inspection of the pavers: if efflorescence is not that heavy or noticeable you can proceed to clean and seal.How do I choose a Sealer?
Your choice of sealer depends on the look you wish to achieve. All sealers will inhibit stain penetrations; some will provide a high sheen or gloss while others will only enhance the color and provide little to no sheen. Make sure that you ask your distributor to see samples of the sealers that have been applied to pavers before you make your decision.What tools do I need?
For most residential jobs you will need a five gallon bucket, tape measure, magic marker, stiff handle nylon brush, slit foam roller and pan, garden hose and nozzle, protective eyewear, respirator and neoprene gloves.What are the advantages of sealing my pavers?
Sealers can offer three advantages: they help resist stains, may enhance the color, and bind the sand in the joints to make it difficult for weeds to germinate. Sealers, however, are topical products and must be reapplied regularly (generally every 3-5 years). Only water-based sealers, or solvent based sealers with a low enough VOC rating, can be used in NJ and NYC.What can I do if my pavers are stained or damaged?
One of the advantages of pavers is that individual units can be removed and replaced in these situations. Remove the sand around the paver and then use two flat head screwdrivers to lift the paver out. Rocking the paver gently in a back-and-forth motion will facilitate removal. Some common stain and suggested removal techniques are listed below:Candy, ketchup, mustard, grease from food
– For stubborn stains, apply liquid detergent full strength and allow it to penetrate for 20-30 minutes. Scrub and rinse with hot water. Removal is easier if these stains are treated immediately.Paint
– Fresh paint should be mopped up immediately with rags or paper towels by blotting. Do not wipe as this will spread the paint and extend the job of removal. If the paint is latex and water-based, soak and then scrub area with hot water, scouring powder and a stiff brush until no more improvement is seen. Let he remaining paint dry and remove as described below.Dried Paint
– Scrape any excess oil-based paint, varnish or water based latex point off the surface. Apply a commercial paint remover and let sit for 20-30 minutes. Loosen with gentle scrubbing. Do not rub the loosened paint into the surface of the pavers. Instead, blot up the loosened paint and thinner. Repeat as necessary.How do I remove grease and oil stains from my pavers?
To safely remove grease or oil stains from concrete pavers use a product specifically designed to do just that. An excellent product for this is Paver Reneu Degreaser & Cleaner
. It is specifically formulated to remove grease and oil stains, tire marks and dirt from concrete surfaces. This environmentally safe product is economical for lighter duty daily or weekly cleaning. This is packaged in 1 and 5 gallon containers and is available at many of Capitol’s Authorized Distributors. What is the whitish deposit I see on some paver installations?
You are probably referring to efflorescence, a natural and common occurrence in many concrete and clay brick products. Efflorescence is the result of naturally occurring mineral salts found in the materials used in the production of pavers or block and Capitol Pavers & Retaining Walls, Inc. accepts no liability for its occurrence. When pavers become wet and absorb moisture the mineral salts are dissolved and are drawn to the surface of the paver with the moisture as it evaporates. This is not a product defect or harmful to the pavers and will usually weather away with time. While we recommend that you wait 6 months to a year for it to dissipate, if you don't want to wait for it to weather away you can try Paver Reneu Efflorescence Remover
available through Capitol’s Distributor Network.Will weeds grow between my pavers?
Weeds and grass result from seeds or spores blowing into, and lodging in, the joint sand. This can be minimized by using Techni-Seal’s Polymeric Sand or by sealing the pavers or mixing a pre-emergent granular weed killer into the joint sand. If weeds do appear, a spot vegetation killer (such as Round-Up™) can be used and will not damage the pavers.Can I remove moss or mold from my pavers?
Try Clorox liquid bleach diluted in water (10 parts water to one part Clorox). Be careful not to get it on other plant material. Keep in mind that there is nothing that will keep it from growing back if it's in a shady, damp area. For a more permanent solution, you will need to correct the moisture and shade problems that are encouraging the moss or mold.Capitol Paving StonesWhy do Capitol Pavers make the ideal pavement?
Our pavers are the ideal product for freeze/thaw environments. Proper installation of the product results in a pavement that is rigid, yet flexible. The joints between pavers allow the walkway, driveway, patio, etc. to move without cracking. In addition, they can be "unzipped" to allow for repairs or access to utilities. Unlike asphalt, pavers are virtually maintenance-free. By definition, concrete pavers have a minimum compressive strength of 8,000 psi (about 3 times stronger than regular poured concrete) and a maximum water absorption rate of 5%.Why are they called interlocking concrete pavers?
It is the system that makes them interlocking concrete pavers, not necessarily the shape. When installed properly, the combination of the pavers, bedding sand, edge restraint and joint sand causes them to interlock, allowing them to work as a unified, flexible pavement.Can Capitol Pavers be used for my driveway?
Absolutely! For residential driveways, 8” to 12”of compacted base material is recommended. A standard 2-3/8”thick paver can be used for light vehicular (cars and pickup trucks) applications. A herringbone pattern is most suitable in these situations. The importance of using a sand setting bed…
The material for the bedding layer should be coarse concrete sand. Do not use stone dust or screenings; they do not allow the pavers to "seat" properly and do not allow for drainage. The sand should be an even 1” thick layer. Do not compact the sand setting bed. Do not mix portland cement into the sand used for the setting bed or the joints between pavers. It defeats the flexibility of the system, and it cannot be cleaned off the surface of the pavers.How do pavers compare with patterned or stamped concrete?
Patterned concrete pavements are merely slabs of concrete that are embossed with a pattern. Therefore, they are prone to the same problems with freeze/thaw cycles, namely cracking and spalling. Stamped concrete requires expansion joints every 10 feet or so, which are very distracting in some patterns. Also, unlike Capitol Pavers, patterned concrete pavements don't allow access to underground utilities or the ability to make repairs.. What can you tell me about snow removal and my pavers?
Pavers can be plowed and shoveled just like asphalt or concrete pavements. In fact, the chamfered edges and joints around the pavers promote melting of snow and ice. A plow with a rubber edge is recommended. Do not use sharp objects to chop ice as they can damage the pavers. Both sodium chloride (rock salt) and calcium chloride will remove snow and ice but can harm the pavers (and any concrete surface for that matter). I have an existing concrete walkway that's in pretty good shape. Can I lay pavers over it?
While not the preferred method, pavers can be laid on top of existing concrete walkways. Two issues must be addressed. First, the grade will be raised by about 2 3/8" to 3" (the thickness of just the pavers or the pavers plus the bedding sand). This is particularly critical if any doorways are involved. Second, if the existing concrete slab should raise or drop with freeze/thaw conditions, then the pavers will do the same.How about using Capitol Pavers on my pool deck?
Not only do Captol Pavers make an attractive pool deck, but they also provide a slip-resistant walking surface. Pavers actually are better than poured concrete around pools from the standpoint that the joints will take on moisture and leave the pavement cooler under foot. Like all products that are used outdoors, lighter colors will tend to stay cooler as they reflect the sunlight. Furthermore, our Bullnose Pavers make a nice pool coping. Make sure the base material around the pool is well compacted before installing pavers. Safety covers can also be installed over pavers with the use of special anchors.Does Capitol have an environmentally friendly decorative paver?
Yes, Our Eco-Logic Paver is an attractive, structural paving system designed to allow rainwater to recharge back to the ground rather than run off. Capitol’s Eco-Logic paver promotes the proper percolation of surface water into the ground, thus allowing water to return naturally to it source.
Capitol Wall Systems
What type of footing is required for Capitol Wall Systems?
A compacted stone base is required for all segmental retaining walls. This varies in thickness from a minimum of 4” for our Garden Walls to a minimum of 6” for our larger wall systems. Generally, the higher the wall, the thicker the base. How tall can I build my segmental retaining wall?
Height limitations without Geogrid for all of our retaining wall products are listed within the catalog on the corresponding product pages. Designed and installed properly, segmental retaining walls can be built in excess of thirty feet high! Consult with a qualified contractor or engineer to see what may be required for your project.
What do I use to adhere the caps on my retaining wall?
Use a high strength, flexible concrete adhesive, such as Titebond to affix your wall cap.
What if I want to build a freestanding wall?
No problem! Capitol manufacturer’s both Centurion and Vintage Retaining Wall System to increase your creative options. Our Vintage Wall is available in two heights and 3 different face lengths.When should I involve an engineer in the design of my wall?
We recommend the use of a professional engineer on projects with taller walls (above 4’) or with unusual site conditions (steep slopes, parking lot or structure behind the wall). Local building codes may also necessitate the use of a professional engineer for walls above a certain height. What are tiered walls and how do I plan for them?
Tiered walls are two or more walls placed in a multi-level arrangement. The second wall should be located behind the first wall at a distance of at least twice the height of the first wall under ideal soil conditions (e.g. if the front wall is 3’ high, the second wall should be at least 6’ behind it).
