Road Repair & Maintenance Demand for Cement & Concrete Additives

Concrete can’t tell time and it can’t take a temperature. It will fail when the circumstances are right for failure, and wrong for the user. Trouble never hits at the right time or the right season, thus the demand for cement and concrete additives in Road Repair and Maintenance. In order to strengthen, hasten or alter concrete and asphalt to meet the needs presented by cold or damp weather, there are a variety of cement and concrete additives.

There is no changing the fact that climate and weather changes affect road repair and maintenance. With polyurethane products, road maintenance options are greatly expanded without the use of cement and concrete additives. Rather than deciding amongst the many cement and concrete additives, chemical and fiber—calcium chloride, calcium hydroxide and calcium aluminum hydroxide, fibermesh and wiremesh to name a few, FlexSet provides a simpler stronger road repair.

With polyurethane road maintenance products, concrete repair can be done with no dig-out. Concrete cracks can be fixed whenever needed, ideally when traffic is at its lowest. Doing road maintenance quickly and with minimal manpower means less traffic exposure to employees or if it’s a do-it-yourself project, it can be handled in your free time. Sweep or blow out the damaged area, mix your materials and apply to create a simple concrete repair. When the weather is really cold, add the catalyst and your set up time will be quick and easy.

FlexSet 5-gallon kits will cover approximately 50 square feet of concrete repair. With this kit, you will also need a drill, a pail mixer, a lute or trowel and a broom or leaf blower.

Prep the Surface
Make sure area is clean and dry. Clean out with a broom, brush or blow out any concrete cracks or potholes with a leaf blower or compressed air to remove any debris or loose material.

Mix the Material
Open the FlexSet bucket and remove 12-pound bag of topping sand and both “A” and “B” bottles of polymer and shake both bottles, mixing well before use. Add the “A” bottle of polymer to the 5 gallon container of treated sand and mix with a pail mixer for 1 minute or until sand mixture is completely wet. Next, add contents of the “B” bottle and mix thoroughly until mixture is combined well. The material is now ready to be applied.

Apply the Product
Using a trowel or lute, spread the mixture over the concrete repair area. The outer areas of the repair can be feathered into the existing surface for a smooth finish. Next broadcast the included topping sand evenly over the repair area. For potholes or deep cracks, an aggregate can be pre-placed, and can be added to your FlexSet kit at no extra charge.

Cure
Cure for about an hour in warm climates. In colder areas a catalyst can be supplied (free upon request) to speed up the cure time.

How to Repair Cracks in Concrete

Concrete cracks are caused by many things-- earthquakes, water, tree roots, frost heaves, poor placement of seams between concrete slabs, even cement mixed with too much water. Whatever the cause of your concrete cracks, polyurethane repair product can give you a stronger faster concrete repair than anything else available.

It is essential to deal with concrete crack repair as soon as you notice a crack appear. Concrete cracks may start small, but if left unrepaired, are guaranteed to grow larger. If cracks become too large, or there are too many, the concrete may need to be replaced rather than repaired.

Standard concrete repair methods are time-consuming, require many tools and sometimes significant labor and can take a long time complete. Roklin's concrete repair products provide several options, ready for use on most any concrete repair project. Using Roklin’s simple methods, there is no need for major preparation—no grinding, drilling, pressure washing or saw-cutting cracks. Simply sweep or blow out the damaged area, mix your materials and apply for solid concrete crack repair.

Whether you have basement concrete cracks, concrete foundation cracks, concrete slab cracks or cracks in concrete walls the process is basically the same. See below for recommendations

Hairline Cracks
Sealing concrete cracks can be done 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. Note: cracks in concrete walls are better handled with the standard dry-wall patch.

Concrete Crack Patch
To repair a crack in concrete that is quickly widening, use Roklin’s FlexSet Concrete Repair Product. FlexSet provides a fast-setting repair that will be a stronger concrete crack patch 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 the deeper area of the crack, 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 in less than an hour.

Concrete Foundation Cracks, or Concrete Slab Cracks

For concrete foundation cracks or concrete slab cracks, use FlexSet to stabilize and fill any voids. The polymer-based repair works in areas where the cracks are deeper and wider, the material flowing down to fill the entire space. With no saw-cut or demolition required, the preparation is quick and easy.

Make sure that the damaged area is clean and dry, with no loose debris. Place the aggregate provided in the FlexSet package to fill in the deeper area of the crack, without going above the damaged area. Using FlexSet bottle "a", carefully pour contents 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 cracks and use a trowel or lute to smooth material into cracks. When cracks are smoothed out, toss topping sand by hand over repaired area to create a smooth surface. In colder months or when there is little time for the repair, catalyst can be supplied as an additive to speed the reaction. The newly-filled cracks can be ready in less than an hour.
