Exterior Repairs
Use Flexible Cement II™to repair cracks and protect control joints in parking structures, bridge decks, loading docks, and many types of structural concrete.
Control Joints
Use on industrial floors to protect saw-cut control joints from wheel traffic damage.
Cove joints
Use Flexible Cement II™ to seal cove joints where the floor meets a structural wall.
Electrical Podding
Seal electrical loops and embedded lighting systems.
Thresholds
Repair concrete thresholds with high thermal differentials.
Moisture
Flexible Cement II™ is tolerant of surface moisture when applied. Concrete should be as dry as practical to insure a good bond.
Concrete Bonding
Flexible Cement II™ is an excellent flexible adhesive for bonding metal, wood, and synthetic materials to concrete. Use to bond moldings and tack strips to concrete floors.
Bond asphalt to concrete.
Bond wood to concrete.
Bond metal to concrete.
Bond carpet nail strips to concrete.
Bond carpet molding to concrete.
High Traffic
Repairs are tough and can handle heavy industrial traffic.

 

Use Flexible Cement II™ to protect joints and cracks in concrete bridge decks and pavement where heavy traffic is anticipated.  This polyurethane is about as hard as a roller blade wheel and will prevent debris from filling cracks and causing further deterioration of the concrete.

 

Flexible Cement II™ is recommended for low movement crack repair. This tough material will hold up to forklift and industrial traffic while allowing for some movement.  For high movement areas and expansion joints, we recommend a softer caulk type material.

The passenger tram at this airport gilds on pillows of air. Flexible Cement II is used to prevent the expansion joints from damaging the air pillows.
One of the 12 air pillows that support each car. Flexible Cement II™ prevents metal expansion joints from lifting up and cutting the air pillow as the car passes.
Flexible Cement II™ is used to protect the interface between the metal expansion joint and the concrete. This allows for a smooth surface for the air lift cars to glide over.

1 Comment

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.
