Question 1     January 25, 2012

Category:  Cleaning/Sealing

Subject:  sealing pavers around a pool

We are thinking about sealing our pavers around pool deck. Need to find out what product to use that will be heat resistant and not be slippery for our kids?

.......................

For around pool decks, I would recommend a penetrating sealer that is specifically developed for concrete pavers. Do not use anything that is film forming or listed as “multi-Purpose Concrete Sealer). Contact a concrete paver manufacturer for a recommended product. There are penetrating sealers at select local locations.

Visit this web site to find a location near you http://www.oldcastlecoastal.com Be sure you have the pool deck clean and thoroughly dry before applying the sealer. And do not apply the sealer if the temperature goes below 65 degrees.

Subject:  Brick Pavers

Can I installed thin brick pavers over my driveway, walkway & entry?

.............................

Thin brick pavers were developed for pedestrian use only where the load bearing weight is minimal. So, you can use them on your walkway and entry but NOT on your driveway. They are not thick or dense enough to handle vehicular traffic and they will break.

Subject:  setting bed for travertine pavers over concrete deck

Our contractor used recycled concrete material instead of masonry sand to set our pavers on our existing concrete pool deck.(the specs. called for masonry sand).Every time it rains the white concrete powder in the base material comes to the surfice and stains the pavers.

Is the recycled concrete material
normally used for this
appliciation?

Hello Tony,

Although recycled concrete performs well as a paver base material, due to its high lime content, it is not the best choice for bedding sand.

What you are seeing on your pavers is the soluble salts coming out of the recycled concrete during the hydration process after a rain or getting wet through a sprinkler or garden hose. It is called efflorescence. These white stains can be removed by using a proper efflorescence cleaner.

In my experience flagstone may delaminate due to water penetration during the freeze/thaw cycle that we experience. Are there any penetrating sealers such a silane/siloxane or a different recommendation that can minimize or block water penetration for this application. If it is a topical sealer they tend to be slippery and create a falling hazard. I would appreciate any advice. Thanks

Question 5     August 06, 2011

Category:  Pavers

Subject:  driveway

we are torn on oyur driveway pavers we are doing traveretine for our pool and wanting the same for our drive way, how durable is the travertine we see alot of them around town and occassionally some with cracks we have and f250 and a 10,000lb boat that will be backed over the driveway throught the years, (not stored on just backed across) we were going to do cement pavers for durability but it seems aas if they fade in only a couple of years, is brick pavers better for fadeing if indeed we need to resort to the paver over the travertine.. thanks Nikki

Hello Fish-Aholics,

Segmental paving is a system and the pavers are the wearing surface of the system. It is important that a proper base is installed to be able to support your vehicular loads. Please check the ICPI.org web site for proper base requirements.

Travertine is a very rich look, but unfortunately there are many different grades of travertine that may all look the same but not perform the same. Concrete pavers are produced under strict guidelines with a compressive strength of 8,000 psi. Besides the required psi strength, they have to meet ASTM C936 for absorption, and thickness. Travertine is a natural product and there is no ASTM (American Society of Test & Measures) specification for travertine.

Keys to keeping your concrete pavers looking new is regular cleaning with a product designed for concrete pavers and when the pavers are completely dry, apply a sealer developed for concrete pavers. OldcastleCoastal located in West Palm Beach manufactures a large selection of high quality concrete pavers. They also carry a complete line of concrete paver care products. OldcastleCoastal is located at 7167 Interpace Rd, WPB, FL 33407 (800) 226-0004
