Repair polished concrete with Concrete Mender™
Stop repairing polished concrete with polyurea joint fillers. They look like plastic, do not bond well, and do not hold-up over time. Concrete polishing lets the natural beauty of stones, sand, and rock shine through. Your repair product should as well.
We took the proven Microdoweling™ properties of Roadware 10 Minute Concrete Mender™ and combined it with natural sands, aggregates and pigments to make repairs that not only look great, but perform better than epoxies and polyureas. The repair pictured above shows Roadware Concrete Mender™ Off-white blended with plain concrete sand and a small amount of portland cement. This water-thin polyurethane is almost translucent. When we add nearly any type of dry sand or aggregate, we get a fast-curing polishable repair that blends beautifully with the surrounding concrete. Since this material is almost translucent, it resists shadowing effects due to over-banding when applied.
Repairing Cracks in Driveways and Patios Updated
One of the most common calls we get is asking how to repair a crack in a driveway or patio. We designed Roadware MatchCrete™ Clear with this in mind. Roadware MatchCrete™ Clear is a UV stable clear polyurethane hybrid that makes effective repairs to most exterior concrete surfaces. By simply leaving the repair clear, the color of the surrounding concrete shows throughout the repair.
The first step to a good looking crack repair is to rout-out or cut the repair open with a diamond blade grinder. You only have to go about 1/4" x 1/4". This will create a recess for the material to rest as it soaks down further into the crack. Skipping this step will allow the material to flow uncontrollably on the surface and will create a messy looking repair.
Apply cartridge mixed MatchCrete™ Clear directly to the crack. Small amounts of silica or quartz sand can be added to keep the material from flowing out the bottom of the slab. If necessary, matching colored sand can be used to match colored concrete areas. Fill the crack to slightly below grade to prevent material from flowing on to the surface of the concrete.
After a year of service, the repair above still looks good. Please note, MatchCrete™ Clear is not a soft expansion joint material and should not be used in joints that are designed to move. Always give careful consideration as to why the concrete cracked in the first place and what the concrete is expected to do in the future before making repairs of this nature. UPDATE: September, 2013 We have a new video for driveway hairline crack repair:
Using Roadware MatchCrete™ Clear to repair cracks on the historic Stone Arch Bridge.
This week the City of Minneapolis used Roadware MatchCrete™ Clear to repair cracks in the exposed aggregate walkway surface on the Stone Arch Bridge in Minneapolis, Minnesota. The Stone Arch Bridge is unique to the Mississippi River and features 23 arches, is 2100 feet long and 28 feet wide. The bridge was built by railroad baron James J. Hill in 1883 and served as a working railroad bridge until 1965. Today the bridge is mostly used by walkers and bicyclists. The bridge also hosts many festivals and public events in the summer months. In preparation for the summer festival season, City of Minneapolis crews used Roadware MatchCrete™ Clear to repair cracks in the exposed aggregate walkway surface. MatchCrete™ Clear is combined with matching rock to repair cracks and restore a consistent walking surface. The process begins with routing out the cracks with a dry diamond blade to remove loose dirt and debris. Clean and dry matching stone is placed into the crack up to surface level.
Matching stone is added up to the surface level
Next, two-part blended MatchCrete™ Clear is poured into the repair up to the surface. This fills in all the voids between the stones and seals the crack. MatchCrete™ Clear is a semi-ridged material that will support all kinds of traffic from pedestrians to industrial fork lifts.
MatchCrete™ Clear is added to the pre-placed stone
See video MatchCrete™ Clear application video below:
Repairs will have a, wet" look for a few months and will naturally dull over time. A clear coat sealing over the entire surface will off-set this effect.

In a few months, Repairs with MatchCrete™ Clear will dull and blend into the surrounding concrete.
Over time, repairs will become less shiny.

Yellow safety marking can be permanently installed in concrete floors with this material. The photo above shows MatchCrete™ Safety Marking after a year of commercial service. Bill Smith, US Food Service, Wixom, Michigan. After years of frustration trying to keep safety line marking in place in a cold storage warehouse, Bill Smith of US Food Service in Michigan started looking for a better way. Installing safety line marking in a 38°F cold storage warehouse is especially challenging. With the 24/7 operations and the heavy fork lift traffic, there was never enough time to let traditional marking paint to cure without the forklift tires marking up the paint. At cool temperatures, the cure times were even slower. Marking tape fared no better. The cold concrete was hard to adhere to and the heavy traffic would quickly damage the marking tapes. Bill was using Roadware 10 Minute Concrete Mender™ to repair cracks, joints, and spalls in the warehouse floor. He liked the fast cure times at low temperatures and he noted the repairs hold up very well to forklift traffic. Bill thought, "What if we could fix our safety line issue with Concrete Mender?" After experimenting with different types of Yellow sand and a request into Roadware for MatchCrete™ Concrete Mender factory colored in Safety Yellow, the line marking MatchCrete™ system was born. After much experimentation, here is the system that works the best. 1. Scarify a shallow recess in to the concrete the length of the line marking. This can be done any number of ways. Stacking several diamond blades together and placing a temporary saw guide works best. Cut the recess about 1/4 inch deep and 1 inch wide. 2. Vacuum all dust and debris from the saw cut area. Mask off the recess with duct tape. 3. Carefully flood the recess area with Safety Yellow MatchCrete™ Concrete Mender. A small amount of safety yellow quartz sand may be used to choke-off any material that flows too far into any cracks or joints. The top of the material should be slightly recessed and smooth. The lines will be ready for full traffic in about 15 minutes at room temperature. Give them a few hours to cure if working in a cold room or freezer. No special maintenance is required.
