Metro Line 4 is a rubber-tired line with 14 stations and runs driverless with pneumatic tires on a 6.7 mile (10.8km) concrete track. Concrete Mender is used to structurally repair the cross joints in the track approximately every ten meters.
Concrete Mender is the right product for the job because it has a long service life and cures in about 10 minutes. This allows for minimal down time and keeps the Busan Metro Line 4 running on time with minimal service interruption.

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.

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.

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.
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 evasive techniques can help keep dust exposure to a minimum.
