What is efflorescence?
Efflorescence is a whitish, powder-like deposit that can sometimes appear on the surface of the paving stones. It may appear immediately or within a short time after installation. Efflorescence occurs when natural salts come to the surface and leave behind a white deposit that can normally be brushed off. Left alone, normal wear and exposure to the elements will dissipate the efflorescence. This is not a product defect or harmful to pavers and walls. To remove the efflorescence before it wears away naturally, best results are obtained by using an efflorescence remover. Do not use muriatic acid. If a sealer is to be applied to the paving stones, it is recommended that any presence of efflorescence be removed prior to sealing. Precautions for proper drainage of the paving stone system should be taken to minimize the occurrence of efflorescence.

What is Geogrid?
All walls over three-feet 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 lengths of geogrid.

What is Polymeric sand?
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.

Can Paving stones be installed over a poured concrete base?
Care must be taken so that water does not pool underneath the pavers. Drainage holes should be drilled in large slabs, filled with pea gravel and covered with landscape fabric. Edge pavers must be restrained to keep joints from opening up.

Is sealing my Paving stones necessary?
Pavers are extremely durable. Sealing, however, may enhance the colors and may prevent staining. Allow a minimum of 60-90 days after completion of the installation before sealing. Consult our team for recommendations on cleaning and sealing.

How many Bricks will I need for my project?
Determine how many square feet you are covering with brick, then select a brick size (see below). Multiply the total number of square feet by the brick needed per square foot, and divide by 5% to allow for breakage. Brick sizes are approximate.

Size                                                      # of brick per SF            # of brick per SF
