Broken Concrete Repair

Unlike standard concrete repair, with FlexSet, there is no need for dig-out or removal of damaged concrete. The tools and labor are minimized. If the concre te damage is minor, a bucket or two of broken concrete repair FlexSet will suffice. If your broken concrete repair is much larger, we recommend using FlexSet with a motorized mixer. For a small broken concrete repair FlexSet repair, you will need a drill with a pail mixer, a broom or blower and a lute or trowel. With a larger broken concrete repair  you will need Roklin's Motor Mix Machine, specially coated aggregate (supplied) and buckets of FlexSet.

Make sure your damaged concrete is clean and dry before beginning.

For a small broken concrete repair, using Roklin's 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 broken concrete repair FlexSet onto damaged area and use a trowel or lute to smooth material into cracks. When damage is sufficiently smooth, toss topping sand by hand over repaired area to create a uniform look and feel.

For a larger broken concrete 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 repair 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 Motor Mix Machine, 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 concrete 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 broken concrete repair area can then be returned to traffic, sometimes in as little as 30 minutes.
