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.
Some people question why these types of cracks should be repaired. Cracked floors in industrial and commercial settings are a liability. The cracks will continue to get larger as wheeled traffic starts to crush the sidewalls. (More) Cracks will also fill with dirt and debris creating a hard to clean surface. Roadware 10 Minute Concrete Mender™ is a structural polyurethane that will restore load transfer and can bring a floor back to original serviceability.
This three level Amazon Warehouse developed thousands of linear feet of shrinkage cracks prior to being places into service. Roadware 10 Minute Concrete Mender will be used to repair them.
Use sacrificial vinyl weatherstrip to make a dam parallel to the cracks that will hold Roadware 10 Minute Concrete Mender™ in place while it soaks down into the cracks. Concrete Mender™ is nearly water thin when mixed and will flow easily deep into open cracks. Since Concrete Mender™ will start to gel up in 5-7 minutes, it will naturally self-seal the bottom of the crack as it cures. It sometimes takes three of four light pours of material, but it will fill the crack completely and start the structural Microdoweling™ process. Microdoweling™ is how Concrete Mender™ uses low surface tension and molecular attraction to penetrate concrete surfaces and locking into the aggregate and rock matrix.
With Concrete Mender™, expensive pumps and equipment is not needed. Once cracks are vacuumed and the surface is cleaned. The weatherstrip dam can be applied. Roadware 10 Minute Concrete Mender™ can be mixed on one gallon batches by hand in a bucket and poured directly into the cracks. Additional manufactured sand can be added for larger cracks, but it is not recommended for this type of repair. See more here: Concrete Mender Bulk Application Instructions
When the Concrete Mender™ cures in about 10 Minutes at 72 degrees F (21C) , the weather stripping and excess material can be shaved clear or ground smooth with standard equipment.
After buffing and clearing excess material, floors can be returned to service immediately.
Finished concrete crack repair blend in nicely at an Amazon warehouse using full depth Roadware 10 Minute Concrete Mender™.
Additional buffing and service traffic will blend the repairs even more into the surrounding concrete.
