Google has spent the last few years mapping and photographing roads all over the world. If you know where to look, you can see actual concrete repairs with Roadware 10 Minute Concrete Mender™

The Google Map photo below shows actual bridge deck repairs with Roadware 10 Minute Concrete Mender™ on Interstate 279 in Pittsburgh, PA.  See all the lighter colored spots? Each one is a hole or spall filled with Roadware 10 Minute Concrete Mender™. The repairs here are over three years old. Thank you Roadware distributor, Express Polymers, Inc., in the Pittsburgh area for sending this project in.

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.

Gravity Crack Injection

UPDATE: See: Concrete Mender™ Full Depth Crack Injection

Roadware 10 Minute Concrete Mender™ is an excellent choice for repairing full depth concrete slab cracks. The very low viscosity of less than 8 cps and the exclusive Microdoweling™ penetration properties of the material allow it to flow deep into cracks. The procedure below illustrates Microdoweling™ in action.  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.Here is a parking deck project located in the North Eastern United States. Hairline cracks run 9-12 inches deep through the deck slab. The contractor drilled 1 1/2 inch holes, 2-3 inches deep into the hairline cracks approximately every 18 inches. Inspection from the floor below reveals full penetration without pumps or ports. Engineers tell us that Roadware Microdoweling™ is quicker and more cost effective than epoxy injection.  The results speak for themselves.
