Why do EP Henry 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.

Does the color go all the way through the paver?
Most EP Henry Pavers (other than Coventry® Bullnose) are manufactured with the Durafacing™ process which concentrates an extra dosage of cement and pigment on the wear layer. You'll never wear through this layer over the lifetime of the installation. Our non-Durafaced pavers have pigment throughout.

Someone recommended that I use a fabric under my installation. When and where is it used?
EP Henry recommends a separation fabric (e.g., Mirafi® ‘s 500X) under all paver installations. The fabric is laid on top of the compacted soil in the excavated area and keeps the aggregate base material from working its way into the soil subgrade. This is especially important where the soil contains a lot of clay. At a cost of pennies per square foot, the separation fabric provides an insurance policy against base failure.

Can EP Henry 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. Typical Patterns (1.11 MB PDF)

Tell me about the 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. We GUARANTEE that EP Henry Pavers won't crack or spall; you cannot obtain a similar guarantee for stamped concrete. Stamped concrete requires expansion joints every 10 feet or so, which are very distracting in some patterns. Also, unlike EP Henry Pavers, patterned concrete pavements don't allow access to underground utilities or the ability to make repairs. At virtually the same price per square foot installed, EP Henry Pavers are clearly a superior choice.

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.

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 adding SandLock to your 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.

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.

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). EnvironMelt is an effective and safe de-icer for your paving stone installation.

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.

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.

How about using EP Henry Pavers on my pool deck?
Not only do EP Henry 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.

What type of sand should I have in between my pavers?
The proper sand for sweeping into the joints between pavers is either mason's sand or coarse washed concrete sand. Both of these have a larger grain size than play sand, which will tend to blow or wash out. If you wish to stabilize the sand in the joints between your pavers to prevent washout and to thwart weeds and insects, use either EP Henry's Polysand or Techni-Seal's Polymeric Sand. Both of these are available at many of our distributors. If you are replacing existing joint sand with polymeric sand, you must carefully remove it to a depth that is 1"-1 1/2" from the surface of the pavers before reinstalling. Careful use of a pressure washer will achieve this; make sure you don't disturb the bedding sand. Without a sufficient amount of polymeric sand the cohesive strength needed to stabilize the sand joint will not be achieved. Make sure that you read and carefully follow all of the directions of the product before you start your project.

My house was recently built, 5-7 years ago, should I expect my contractor to reinforce my homes foundation prior to my Hardscape installation due to continual settlement issues?
Yes. If your house has been constructed within the past 7 years, there is a good chance that a 4' x 4' zone surrounding the homes foundation may add to continual settlement of the existing soils or a new Hardscape installation. The area can be reinforced in a number of ways, but must be addressed prior to Hardscape construction beginning. Please download our recommended engineering solution in PDF format.

Does EP Henry have an environmentally friendly decorative paver?
Yes, Our ECO Paver is an attractive, structural paving system designed to allow rainwater to recharge back to the ground rather than run off. With impervious coverage becoming an increasingly hot topic, EP Henry is proud to have been recognized by Building Green as a "Top-10" Green-Spec product for our ECO Paver. For more information about the ECO Paver, please go to the "Products" and/or "Technical and Construction Information" sections of our website and click on Environmental Paving Systems. There you will find specs, images, infiltration tests and installation guidelines for ECO Paver, and our other pervious pavement systems.

How 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. If you have a lot of rainfall in the spring, 3 months should suffice. If your installation was done in June and we have a dry summer, you should probably wait at least 6 months. 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.

What does it cost to clean and seal my project?
Depending on the amount of stains you have and the sealer you choose, the average cost would be less than $1.00 per square foot if you do it yourself.

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 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 EP Henry 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, Techni-Seal offers an excellent cleaning product to remove it. Visit EP Henry’s Cleaners & Sealers page. Once the pavers are cleaned it is recommended that they be sealed.

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 Techni-Seal's Dirt and Grease Cleaner. It dissolves, dislodges, and encapsulates grease and oil so that it can be rinsed away. This is packaged in 2 quart containers and is available at most of our Authorized Hardscaping Centers. If you want to seal your pavers to help prevent future staining, we recommend sealers from Techni-Seal and SureBond. Before sealing your pavers you should do a general cleaning of the entire surface to remove any soils or surface efflorescence. Techni-Seal General Cleaner and Efflorescence Remover is a great product for this purpose. A word of caution: make sure that the pavers are completely dry before applying the sealer.
