The Basics on Patching & Repairing Concrete

Roklin Systems

Concrete damage can be a big problem, but with polyurethanes, repair can become a small thing. Polyurethane concrete repair products can be used for concrete repair of almost any size—hairline cracks, potholes and spalls

Standard concrete repair methods are time-consuming, require many tools and sometimes significant labor and can take five days or more complete. Roklin’s concrete repair products provide several options, ready for use on most any concrete repair and restoration projects. Using Roklin’s simple methods, there is no need to grind, drill out, pressure wash or saw-cut cracked or damaged concrete. Simply sweep or blow out the damaged area, mix your materials and apply.

Hairline Cracks :

Hairline Cracks can be filled simply using Concrete Welder, available in a cartridge format. Make sure the crack is clean and free of moisture. Open cartridge and squeeze Concrete Welder directly into the crack. Use a scraper or straight-edge to smooth the material out. Wipe up any excess material and allow to dry for 30 minutes. Now the crack is filled and ready for use.

Potholes :

To repair a hole in concrete, use Roklin’s FlexSet Concrete Repair Product. FlexSet provides a fast-setting repair with almost no interruption of service.

First ensure that the damaged area is clean and dry. Sweep or blow out cracks so there is no loose debris. Place the aggregate provided in the FlexSet package to fill in some of the pothole, without going above the damaged area. Using FlexSet, carefully pour contents of bottle “a” into provided 5-gallon bucket then add special sand. Next, shake bottle “b” thoroughly and pour into sand mixture. Mix with a paddle-mixer, using a drill. When mixture is completely wet, pour FlexSet onto damaged area and use a trowel or lute to smooth material into cracks. When damaged area becomes sufficiently smooth, toss topping sand by hand over repaired area to create a uniform look and feel. The new repair can be ready for traffic in less than an hour.

Spalls :

For a concrete spall repair, use FlexSet with a bucket mixer. The polymer-based repair works in areas where there is a lot of movement, damaged base or where other concrete repairs materials have failed. With no saw-cut or demolition required, the preparation is quick and easy.

Sweep or blow out damaged area. Place the 5-gallon pail on the Roklin Motorized Pail Mixer, ensuring the pail is secure in the correct slots. Pour the contents of bottle "A" into the 5 gallon pail, making sure it doesn't splash out. Pour the supplied 30 pounds of specially coated aggregate into the pail, covering the A side. After shaking the contents of bottle "B" for 20 seconds, pour the contents into the 5 gallon pail.

On cold days or when there is little time for the repair, supplied catalyst may be added to speed the reaction. Spray a light coat of vegetable oil on the paddle in order to keep the paddle clean. Place the paddle in the pail, turn on and mix for one minute before adding aggregate.

Next, add 25 pounds of Roklin Black Diamonds 3/8" aggregate and mix for one minute. Pour into spall which can be filled to grade as material is free-flowing and self-leveling. The polymer slurry can now be feathered into the existing concrete, ensuring a smooth ride. Broadcast the supplied 12-pounds of topping sand over the area to create a high traction surface. Once fully cured, the area can then be returned to traffic, sometimes in less than 30 minutes.
