Contractor uses 10 Minute Concrete Mender to make pebble-crete floor.


Basic SYSTEM in Bahrain is using Roadware 10 Minute Concrete Mender™ to make rapid curing pebble-crete flooring in Bahrain. The easy mixing Concrete Mender combines with the pebbles and acts as a binder in seconds. The mixture is easy to apply and trowel flat without getting sticky until the final minutes of curing. See the video here.

“I will take the opportunity of this e-mail & send you a recent photo of the pebbles application with Concrete mender at PinkBerry frozen yogurt / pictures was taken today, the floor is performing well and the client is very happy / the application will be repeated in Future PinkBerry shops in the region…”

Pebble floor application at a Pinkberry Store in Bahrain. 

600ml of Roadware 10 Minute Concrete Mender™ is combined with about 6kg of 3-5mm pebbles. The components are mixed be hand, spread out on the floor about 3cm deep and troweled flat. 600ml

The pebbles are completely coated and help in place by the Roadware 10 Minute Concrete Mender™. The floor performs well and creates the look specified by the designer. The floor does not need further sealing. Daily maintenance consists of vacuuming and mopping.

When I first saw this application, I had some questions:

Hello George at Basic SYSTEMS in Bahrain.

Your application has not been tried before with Concrete Mender.
How does the surface look?

It’s giving a wet look / looking really nice.. they have used resin in the past in other outlets, but the problem it was not strong enough and was smelling due to cleaning process.

Are the rocks coated completely?

We have mix it with in a bucket with the Concrete Mender / pebbles size was 3 to 5mm, we have used 600 ml of CM and an average of 6 kg of pebbles, it was completely coated

Do any of the rocks come loose? 

Yes some, but it was superficial, we brush it out with hard brush the next day and fill the few areas where the pebbles was removed with same mix materials…

Will the floor be easy to clean?

Well vacuuming and mopping was our instruction to follow…

Do you use a clear sealer after the application?

The pebbles are completely coated/ by sealing it, will loose the natural look as required in the concept design.

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.

Update: June 24, 2012.
