I have white deposits or film on my pavers/walls, what is it?

You are probably referring to efflorescence, a natural and common occurrence in concrete products. Efflorescence occurs when natural salts come to the surfaces and leave behind a white deposit that can normally be brushed off. This is not a product defect or harmful to pavers and walls and Lowcountry Paver accepts no liability for its occurrence. It will usually weather away with time. If you prefer not to wait for nature to take its course, efflorescence cleaners can be purchased that will help remove the residue and restore the color.

Can pavers be installed over a poured concrete base?

Absolutely, but steps must be taken so that water does not sit underneath the Lowcountry pavers. Drainage holes should be drilled through the slabs, filled with pea gravel and covered with landscape fabric to provide proper drainage.

Why do my 1 inch Thin Pavers over concrete seem to have more efflorescence than the 2 3/8 inch pavers?

Thin pavers laid over top of existing concrete without drain holes as described above cannot drain as well as pavers laid over a stone and sand base. Since efflorescence is drawn out of concrete by moisture and humidity, this excess moisture causes the efflorescence to appear more rapidly and dramatically than pavers over sand.

Can Lowcountry Pavers be laid over an existing driveway?

Yes, if site conditions permit, our 2 3/8” pavers can be laid over an existing driveway without the need of removing the existing concrete. Some contractors have used our 1” thin pavers for driveway overlays with good results, however, we do not recommend this or guarantee 1” paver for vehicular traffic.

Which color is best for a paver pool deck?

Lowcountry Pavers make a terrific slip-resistant surface around pools. Because people are often barefoot on pool decks, we recommend our “Cool Pool” color collection which are the coolest pavers on the market! A less expensive option would be the lightest colors in our “Coastal” color collection such as “Toasted Almond”. The least expensive option would be “Spartina”, the lightest color in our “Lowcountry Traditional Color” collection. These colors will put off the least amount of heat. Patios usually aren’t as critical as pool decks for heat, but it should be considered. If your patio is in a shady area, any color should be fine. Please keep in mind that even beach sand gets hot in the middle of summer so although our “Cool Pool” color collection is the coolest, it is still possible that they could be hot on the feet. Please contact Lowcountry Paver for a list of temperature readings!

What is the best color to use on a driveway?

Our “Lowcountry Traditional Color” collection is recommended for driveways because they are darker and usually hide tire tracks better. If you do decide to uses a lighter color for a driveway, it is recommended that you thoroughly clean and seal the driveway to help avoid staining and tire marks.

What if I don’t see the color I am looking for?

We have over 50 special order colors available, as well as solid colors and our custom color matching lab can match almost any color imaginable. Contact Lowcountry Paver for more details.

Why did my Lowcountry pavers lose their color?

Efflorescence causes a white film on top of the paver that gives the appearance that the color has “washed out” of the paver. Most often, a simple cleaning with efflorescence cleaner will restore the true color back in your paver.

Does the color go all the way through Lowcountry Pavers?

Yes! Unlike many face-mix pavers that have color in a very thin veneer on the surface, Lowcountry Pavers have color throughout.

What thickness paver do I need for a patio or pool deck?

Any thickness will be fine since this is a non-vehicular application. If it is an existing concrete overlay, our 1” Thin Pavers or 2 3/8” are recommended. For new construction, our 2 3/8” will be the least expensive and most popular option.

What thickness paver do I need for a residential driveway?

Residential Driveway’s require 2 3/8” or 3 1/8”. 3 1/8” is only necessary when using the Olde World Cobble or SF-Rima Permeable Paver.

What thickness paver do I need for a commercial or industrial applications such as a parking lot or road?

For commercial and industrial applications, only our 3 1/8” thick pavers are guaranteed not to crack.

I’ve got a railroad tie wall that is rotting and falling down. What can I do?

Our segmental retaining wall systems provide an excellent solution to this problem. They are strong and will last a lifetime. Lowcountry Paver offers several different wall systems to meet your needs.

Which paver shapes have a flat surface?

Although all of our shapes have only a slight texture for ease of walking and to help avoid tripping hazards, Plantation Paver, Tru-Brick, Perma-Flo Cobble and the Mall Stone shapes have completely flat surfaces. Also, almost all of our pavers can be laid upside down for a completely flat surface as well. Since the moisture rests at the bottom of the paver during the curing period in the kiln, the bottoms usually have efflorescence on them and may require cleaning after installation.

Why do Lowcountry Pavers make the best pavement?

Not only are Lowcountry Pavers beautiful, but installation over a compacted aggregate base results in a pavement that is strong, yet flexible enough to move as the ground shifts without breaking apart, rutting or heaving. In addition, they can be “unzipped” to allow for repairs or access to utility lines. Unlike asphalt and other surfaces, pavers are virtually maintenance-free. And, Lowcountry Pavers are about 3 times stronger than regular poured concrete.

What is geogrid and when should it be used?

As a rule of thumb, all walls over 3′ high should be reinforced with geogrid. Geogrid is placed between the layers of block at different intervals to stabilize the soil behind the retaining wall and secure the wall face to the earth behind it. The height of the finished wall, soil characteristics, and the pressure on the wall caused by slopes, structures, and/or paved areas all affect the proper placement and length of geogrid.

How do Lowcountry pavers compare with decorated or colored concrete?

Decorated concrete pavement is regular concrete that has a pattern stamped into it and color usually added to the surface. Just like a basic concrete driveway, it is still vulnerable to cracking and does not allow access to underground utilities or the ability to make repairs. At virtually the same price installed per square foot, Lowcountry Pavers are clearly the superior choice.

How do I determine how much stone base material and sand setting bed material I need?

One half ton of modified stone or sand will cover about 100 sq. ft. at 1″ thick. Using a 10 x 10 (100 square feet) patio as an example, you would need ½ ton of sand for the setting bed (1″ thick) and 3 tons of modified stone for the base (6″ thick). You’ll need about 5% more sand for the joints between the pavers. The thickness of the base material depends on the application and subgrade soil conditions (uses a thicker base for poorly drained soils). As a rule of thumb, you’ll need 4″ to 6″ of base material for non-vehicular areas, and 6″ to 12″ for driveways and parking lots.

What is polymeric sand and what are its advantages?

Polymeric sand is a high-tech mix of graded sand and binder, specially formulated for filling joints between pavers. When installed properly, polymeric sand will remain in the paver joints and inhibit weed growth and insect infestation, as well as sand washout from rain.

What are the benefits of sealing my pavers? How long do I need to wait before I apply a sealer?

Sealers help resist stains and may enhance the color. Some can also bind the sand in the joints to make it difficult for weeds to germinate. As a rule of thumb, we generally want you to wait at least six months to allow any efflorescence to appear. Prior to the application of any sealers, the pavers must be cleaned with an appropriate product to remove dirt and efflorescence.

What can I do if my pavers are stained or damaged?

Special products are available to clean stains from concrete products. If they are exceptionally stained or damaged, individual units can be removed and replaced. Remove the sand around these pavers and use a paver extractor (or two flat head screwdrivers) to lift the paver out. Rocking the paver gently in a back and forth motion will facilitate removal.

How can I remove moss or mold from my pavers?

Try liquid bleach diluted in water (10 parts water to one part bleach). Be careful not to get it on plant material. Keep in mind that there is nothing that will keep moss and mold from reappearing in a shady, damp area.

Will weeds grow between my pavers?

Weeds and grass between pavers occur when seeds or spores lodge in the joints between pavers. They will not grow from underneath. This can be minimized by using polymeric sand 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.
