Maintenance Guidelines for Concrete Paving Products

1 | P a g e

When properly installed, interlocking concrete pavements have very low maintenance and

provide an attractive surface for decades. Under foot and vehicular traffic, they can become

exposed to dirt, stains and wear. This is common to all pavements. These steps include removing

stains and cleaning, plus joint stabilization or sealing if required. Stains on specific areas should

be removed first. A cleaner should be used next to remove any efflorescence and dirt from the

entire pavement. A newly cleaned pavement can be an opportune time to apply joint sand

stabilizers or seal it. To achieve maximum results, use stain removers, cleaners, joint sand

stabilizers, and sealers specifically for concrete pavers.

Concrete pavers can act as a zipper in the pavement. When the need arises to make

underground repairs, interlocking concrete pavements can be removed and replaced using the

same material. Unlike asphalt or poured-in-place concrete, segmental pavement can be opened

and closed without using jack hammers on the surface and with less construction equipment.

This results in no ugly patches and no reduction in pavement service life. In addition, no curing

means fast repairs with reduced user delays and related costs. The process of reusing the same

paving units is called reinstatement. This Tech Spec covers how to reinstate or "unzip and zip"

interlocking concrete pavement. The following step-by-step procedure applies to any

interlocking concrete pavement, including pedestrian areas, parking lots, driveways, streets,

industrial, port and airport pavements.

All concrete unit pavers from Mutual Materials are manufactured to meet or exceed industry

standard specification ASTM 936, Standard Specification for Solid Interlocking Concrete Paving

Units as set forth in the specific product physical requirements for:

• Physical Size (units shall have an exposed face area <=101 in

);

• Compressive Strength (minimum average compressive strength of 8,000 psi);

• Absorption (average absorption no greater than 5%);

• Conformance to Abrasion Resistance Tests (specimens shall not have a greater volume

loss than 0.92 in

within 7.75in

); and

• Dimensional Tolerance (length and width of +/-1/16” and height of +/-1/8”).

Rountine Cleaning

1. Use a stiff bristle broom and garden hose to scrub and clean the pavers.

2. In areas where you have very dirty pavers (like high traffic zones) you may add in some detergent

to the water mix to dislodge dirt from the surface of the pavers. Scrub with push broom and rinse

with garden hose.

Maintenance Guidelines for Concrete Paving Products Joint Sand During normal use, the sand-filled joints receive dirt from traffic on the pavement. Dirt settles into the top of the joints, helping to hold the sand in place. Installations exposed to driving winds or runoff, however, may lose some joint sand that can be simply replenished with dry sand. If the problem recurs, sealers will help hold the sand in the joints.

Maintenance Guidelines for Concrete Paving Products If efflorescence does occur, it can be removed with cleaners specially made for concrete pavers. Careless or improper cleaning can result in damage and discoloration to the concrete paver surfaces. Contact your paver supplier for further information about the chemistry of efflorescence and appropriate commercially available cleaners. ICPI Tech Spec 5—Cleaning, Sealing and Joint Stabilization of Interlocking Concrete Pavement provides additional details.
