How to deal with sand washing away between pavers

around the swimming pool With high traffic areas such as walkways, and pool patios, paved areas can and will lose the sand between them. Here at Gappsi we combat this event by using a long island polymeric sand that hardens after application. This product is very similar to sand with the added bonus of bonding together to form an almost concrete like bond, that expands and contracts with the temperature changes during the year. Not only does it help keep it in place it also inhibits growth of weed. Low maintenance is key when using polymeric sand. Gappsi can design, supply and install your entire project.

Why Seal Your Pavers? Is it necessary to seal paving stones on long island

Sealing your concrete pavers will help protect, keep clean and maintain its original look for much longer. Sealing gives your pavers a protective barrier from stains due to oil grease, any natural occurrences and grime. It helps cleaning, and removing stains much easier than without being sealed. Sealing your pavers is the best way to maintain that new look of your driveway patio and walkway. It creates a clear gloss finish, making the color bolder and distinct, while repelling grease and oil stains.
Sealer Types:
Film Formers
This type of sealer helps to protect your pavers by blocking the effects of water and other contaminants. Film Formers generate a barrier on the surface of the pavers, often a gloss finish. The sheen finish also helps prolong that new look color. Film Formers protect the concrete at the surface, inhibiting water or chemicals from penetrating the concrete. This sealant type adds shine and increases the appeal of the concrete.
This type of sealer actually penetrates into the pavers’ material, from 1 to 4 mls. deep. These sealers are mostly used for absorbent materials such as concrete. Penetrants help to repel water and resist stain damage. Penetrant sealers also promote longevity and durability of the life and look of your pavers.Due to the penetration of the sealer, penetrate type sealers do not typically add shine to the surface
Sealing agents can be applied to most types of surface pavement materials. These include concrete, slate, clay, granite, natural stone, stamped concrete and block pavers.
You can apply sealer agents to your driveway, patio, and all areas that are paved, Wherever sealers are used, the result is always a cleaner brighter long lasting concrete paver.

Efflorescence on Cambridge pavers-cleaning solutions advices Long Island

Efflorescent,Efflorescent is whitish powder that migrates to the paving stone surface. It is not appealing to the eyes and for many consumers it is very disappointing to see this. It is a very normal and natural process for the lime to bleed out of the brand new concrete pavers. It is very unfortunate for the consumers that after spending lots of money they have to be not happy about their investment.
But the problem is not the white powder; the problem is more the fact that the consumer is misled,
Because you get all caught up with all the paving stone s manufactures marketing and fancy names, and you try to make sense of all the paving stone’s manufactures claim of superior products. But the truth is that don’t matter what you buy or witch paving stone brand you use you get the same product just called different name.
Efflorescent will eventually go away, there are products that could clean the white powder residue over the paving stones, but my professional suggestion to clean the efflorescent, is to let the curing cycle of the brand new pavers. This could take several months, but the best solution is to wait 2 full years, and after two years there should be no whiter sitting on the patio and at that moment you can clean the surface with efflorescent cleaner there are few solution that would work the one that we have used and really works is sure clean. It comes in 5 gallons pails; you should dilute the solution with water mixing it 50 /50. The surface of the paving stones should be dry when you apply these products and it should be sprayed on, then using a hard bristles broom you should scrub the stones for about 10 minutes, if the solution starts to dry, apply more on the stones after you are done brushing it. Then you can wash it off with the garden hose. You need water value more than pressure because the chemical does the cleaning not the water pressure. Let the pavement dry and wait a few days And if it is not yet clean enough for you can repeat the process one more time, but it should be good the first time.
Many times the white powder will come back, and this will happened more in the spring time when the weather goes from cold to warm, the temperature change from day to day could bring more lime out of the paving stones and show on the surface3. But this will go away as soon as the weather gets warm.
Efflorescent is just a chemical reaction between the new cement that is used to make the pavers, water and the temperature. the pavers get wet the warm weather dries them and in the process of drying the salts rises to the top of the stones because the heat goes up and it also brings the lime to the surface , and because of the new cement the stone is very reach in lime . And you can say that the better the stones the more white you will get until the cycle stops or comes to a minimum.
It is very important that drainage as to be done correctly under the pavers ,and that is the key to a good installation that it all starts with the installer , having the right installer is the answer to a great installation. For more information or question visit our web site at .

Rock Salt as ice melt: corrosive-recommended-good-suggested-negative

By Giuseppe abbrancati

Rock salt on pavers could be to strong and could damage the pavers
Because the salt grain are big in sizes and as the melt would releases a over concentrate amount of salt in a small area and this would allow the concrete or any surface to absorbe it and get effected by it .porous surfaces get affected more then more solid surfaces.
The best products to use are finer granular ice melt; they are more effective on the snow and less corrosive for the paved surface.
