Repairs are blended in with the surrounding concrete using sandpaper as the product cures.
The sandpaper picks up particles and color from the surrounding concrete and blends hem into the Concrete Mender while it’s in a plastic state. The result is a repair that blends with and closely matches the surrounding concrete. The floor is resealed after and the repairs blend in nicely.

New Concrete Mender™ Mini Cartridge for precise application.

Roadware delimanition repairs are featured in the July 2008 issue of Concrete International. This is the official publication of the American Concrete Institute. The article was written by Nelson Tonet, President of Express Polymers and a Roadware distributor.

ABSTRACT
“Delaminations in concrete floor slabs can be difficult to repair in a cost-effective and timely manner. A newly developed product (Roadware 10 Minute Concrete Mender™) that uses a two-part hybrid polyurethane with a viscosity similar to water can significantly reduce the difficulty of performing delamination repairs by easily flowing up to 10 ft (3 m) from an injection point and penetrating deep into concrete surfaces. The product also speeds up repair by setting in only 10 minutes, allowing the repair to be checked by sounding only 30 minutes after product placement.”

Here is a Roadware synopsis.

Roadware 10 Minute Concrete Mender™ is an excellent choice for repairing concrete slab delaminations. The very low viscosity of less then 8 cps and the exclusive Microdoweling™ penetration properties of the material allow it to flow deep into delaminated concrete voids. The Concrete Mender will restore aggregate interlock and will allow dynamic load transfer under heavy traffic. The expense and mess of pressure injection with epoxy can be avoided.

Two methods of repair have been successful. The first involved dry diamond drilling a 2 or 3 inch (5-8 cm) diameter hole into the concrete slab down to the delamination. Dust is removed with a shop vacuum. Roadware 10 Minute Concrete Mender is poured or pumped into the void. Only one or two inches (3-5 cm) of head pressure is required to push the material as far as 10 ft (3 m) into the delamination. When the material backs up to the top of the hole and the void is filled, silica sand is added and the hole is filled flush with the surface. Soundings are made with a hammer to verify the delamination is repaired in about 30 minutes after application.

Another method is to drill multiple 3/8 inch (1 cm) holes into the concrete down to the delamination. Remove dust with a shop vacuum and inject pre-mixed Roadware 10 Minute Concrete Mender™ with a syringe tipped with a rubber gasket. With this method, you can actually see the material exit the adjacent hole and verify the material is filling the delaminated area. After filling, the holes are blended into the surrounding concrete with silica sand and Concrete Mender or re-drill 1/4″ (5 mm) deep and fill with a color matching concrete mortar.

See the movie:

Both methods will yield good results and are more cost effective than epoxy injection.

Polishing un-polishable Concrete

Polishing and honing concrete to smooth shiny surface is a great way to give an old warehouse floor new life. Sometimes, warehouse floors are too damaged and worn to make polishing practical. Floors that are full of cracks and spalls will require a large amount of grinding and polishing to achieve an acceptable surface. Roadware 10 Minute Concrete Mender™ may be used to restore the concrete surface and reduce the time and expense of heavy grinding. The Microdweling™ action of Roadware 10 Minute Concrete Mender™ can penetrate the surface of the cracks and spalls, fill in all the low spots, and make the floor ready for polishing.

Pitted, spalled and cracked surfaces may be unpractical to polish.

 

The first step is a light surface grinding to open up the cracks and remove any loose materials.

An initial grinding with metal resin pads reveals cracks and spalls.

Roadware 10 Minute Concrete Mender™ and fine silica sand mixed in bulk is troweled into the surface over the entire area and allowed to set.

Workers trowel Concrete Mender into place.

In about 10 – 30 minutes, the surface is polished using standard techniques. Roadware 10 Minute Concrete Mender™ will not gum-up polishing pads or smear into the surrounding concrete.

After grinding, all pitting, cracks and spalls are filled and a smooth surface is quickly restored.

Concrete Mender repairs hold up perfectly during the polishing process.

After polishing, hardening and sealing, a beautiful polished floor is revealed.

Repairing Railings and Posts with 10 Minute Concrete Mender™.

How often have you run into this problem?  Industrial railings that have been split apart due to age, abuse, or weather damage. With a few special techniques, you can repair these problems with Roadware 10 Minute Concrete Mender™.

Clean the repair area with a wire brush or by sandblasting. Remove as much of the rust as possible. It is also a good idea to spray the the steel railing with a rust neutralizer.

 

Make a simple form out of blue foam board, and duct tape or most anything plastic. Do not use wood, Concrete Mender will permanently bond the wood to your railing base.I made that mistake years ago and had to chip, grind and sand the wood off the face of the concrete.

Make your repair by pouring 10 Minute Concrete Mender™ bulk mixed with sand in from the top. Allow to cure and finish the surface with a stone or grinder.

 

Add a quick coating of a latex cement coating and your finished. You may also make repairs around railings with Roadware Flexible Cement II™ if the railing is made aluminum and requires more thermal contraction and expansion properties.

Earthquake Crack Repair at Hope Alive Clinic in Haiti

“Kelton,

In March, you donated the Roadware kit to bind the cracks at the Hope Alive! Clinic in Haiti. THANK YOU FOR YOUR GIVING AND KIND HEART.

We went to the Atlantic City airport with the msds. They refused to allow us to bring the tubes on the plane. (they really didn’t know how to read the msds sheets either)

Anyway, we shipped the package via Philadelphia-container-Haiti. It arrived in time for our July 8th trip.

We brought along a Pastor who is also a “concrete guy”. He stated that he had never worked with a product that was so easy and did such a great job. As you can see in the attached photos, the fissure is completely sealed. As I mentioned in our phone conversation, the epi-center of the quake was only 6-7 miles from our clinic. We even have 2 sets of tubes left over!! (the neighbors will benefit)

I do not know how to say thanks but to just say “thanks” . Your kindness has made a difference with Hope Alive Clinics and the Haitian people. visit www.hopealiveclinic.org for more pictures of the teams and clinic activities.

If you are ever in the Philadelphia area, please look us up.

Again, many thanks and God bless you and your great company.
