The Hong Kong International airport HKG is home to the world’s busiest cargo gateway airport. In 2015, HKG moved over 4.38 million metric tonnes of air cargo. It is also one of the world’s business passenger airports accommodating over 68 million passengers that same year.
Operations at the world’s busiest cargo airport run 24/7/365 without stopping. Maintenance crews need a crack and joint repair material that can be applied in a wide range of conditions and be ready for service in minutes. Roadware Flexible Cement II is a tough polyurethane crack repair material that can be applied at any ambient temperature. It bonds very well to distressed concrete and forms a tough semi-elastic polymer that will withstand heavy airline traffic in about 15 minutes. Crews at HKG airport have relied on Roadware Flexible Cement II to make repairs whenever and wherever needed for over 5 years.

Use Concrete Mender™ to repair cracks, joints and curling slabs under VCT or tile floors. The permanent performance and 10 minute cure turns this 2 day job into a one day (or one night) job. Keep business running with minimal down time.
For spalled or failed control joints that are reflecting through the tile and the slabs are not curled, clean out the joints with a dust collecting diamond grinder.
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.
Reducing worker exposure to silica dust is an OSHA and job site priority.
“Workers may be exposed to dangerous levels of silica dust when cutting, drilling, grinding, or otherwise disturbing materials that contain silica. These materials and tasks are common on construction jobs. Breathing that dust can lead to serious, often fatal illnesses.” The Center for Construction Research and Training. Click here to learn how to work safely with silica.
With Roadware 10 Minute Concrete Mender™, you can make excellent crack and spall repairs with much less cutting and grinding. Standard preparation for most concrete repair products calls for invasive actions from square cutting and removal to deep cutting, grinding and sandblasting. Aggressive preparation is necessary for standard repair material like epoxy and polyureas. They are too thick to penetrate and bond to compromised concrete surfaces. Roadware 10 Minute Concrete Mender™ has an extremely low viscosity of less than 8cps when applied with a surface tension one third of water. Concrete Mender™ can penetrate and bond concrete surfaces where other materials will fail.
Many concrete crack repairs can be made with Concrete Mender™ with just a light scoring with variable speed diamond grinder. This reduces dust production by nearly 70% over conventional methods.
In some situations, cracks can be repaired directly with only a shop vacuum used to remove dirt and dust. Roadware’s needle tip application mixers are great for getting Concrete Mender™ into small cracks in fissures.
Roadware Easy Injection can make low dust repairs 24 inches deep or more without cutting, ports, or pumps.
Full depth crack repair in warehouse floors usually involves cutting open the cracks with dry diamond saws. This is a slow process and creates a lot of hazardous silica dust that needs to be mitigated. Repair contractors at an Amazon Warehouse project are using an innovative way to repair cracks in the floor without the traditional cut and fill methods.
A wire wheel can be used for preparing cracks and spalls. We recommend using a variable speed grinder with a twisted wire wheel. This generates less dust than diamond blades and still does a good job preparing the crack for a Concrete Mender repair.
After the crack or spall is repaired, grinding and buffing to make the repair flush can be made using wet methods in just 10 minutes after application when using Concrete Mender™. Other low dust methods include razor scrapping and dustless grinding equipment.
Whenever cutting or grinding concrete, have a plan to keep harmful dust away from workers and bystanders. Using Roadware 10 Minute Concrete Mender™ with these minimal invasive techniques can help keep dust exposure to a minimum.
