Stamped Concrete Patio Pop-out Repair

11 Comments

Repairing seasonal pop-outs in stamped and colored concrete is easy with MatchCrete™ Clear. Just add some powered pigment or grout to the clear MatchCrete™ aliphatic polyurethane and you can match most any color. Come back after 24 hours and give the repairs a light sanding to blend them in. See the short video below.

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.

MatchCrete™ Clear repairs 18 days later.

 

I revisited the repairs on the bridge 18 days later. The surface has been sealed.  The repairs are performing as expected.

Emergency Concrete Repair at Wal-Mart Garden Center

Recently Dave Wilson, of Roadware Distributor Fowler Supply received this email on behalf of a East Tennessee Construction Services.

From: Retail Facilities Maintenance Call Center
 
Subject: concrete repair
 
Possible safety hazard in garden center patio. Please dispatch concrete repair specialist to evaluate and remedy the situation as soon as possible. Customer safety is a top priority.

Emergency repairs are common for Roadware contractors.  When safety is on the line and a store needs something repaired quickly and permanently, Roadware Concrete Repair Products are the clear choice due to minimal down time and minimal intrusion to facility operations.

When Dave Wilson arrived on site, this is the trip hazard condition he found.

Plan of Action:

  1. Repair bottom portion of spalled joint with Roadware 10 Minute Concrete Mender™.
  2. Repair top portion of spalled joint using new Roadware MatchCrete™ Clear (MCC) colored with Davis Colors pigment to match the surrounding concrete. MCC is used because it will not change color when exposed to UV sunlight as is the case in a garden center.
  3. Finish to grade.

Roadware 10 Minute Concrete Mender™ and silica sand is added to the bottom of the repair. This provides a tough  Microdoweling™ repair and seals off and moisture in the substrate.

Roadware MatchCrete™ Clear and a mixture of silica sand blended with about one teaspoon of powdered Davis Color is added to the repair.

The Roadware MatchCrete™ Clear and sand mixture is troweled in place and allowed to cure for about 45 minutes.

After curing, the surface is ground smooth and the control joint is re-sawn with a diamond blade.

 

Traffic is restored immediately.  Danny, the associate who requested the work order was, “Amazed.”

When the job has to be done quickly and correctly. Roadware Concrete Repair products are always at the ready.
