Perfect CC Midwest Inc carries the necessary preparation saws with associated dust collection vacuums to correctly cut & prepare sawcut joints for our pumping equipment. Joint fill is very important not only in epoxy & polished concrete flooring applications but even whereas the warehouse or large area slab is to remain as is, sealed concrete post pour. The two part polyurea cures rapidly to a rubbery shore hardness of 88-90, allowing ample give under heavy wheeled traffic loads without creating a breaking impact point on joint edges.
Warehouses that have left joints unfilled will have more cracking along joint edges, stone breakouts & higher difficulty keeping floors clean due to the debris getting caught in the joint canals.
Whether it’s a new building prior to use or a building that has decades of heavy wheeled loads, Perfect CC Midwest Joint Fill Services can be extremely beneficial. In the post joint damage scenario, we have multiple processes in rebuilding the broken joints prior to pumping with polyurea and creating a new working load surface.
The products we install have quick 10-minute cure time, guaranteeing very minimal shut down to any of your facilities operations. Typically, thousands of linear feet can be performed by a small crew on a daily basis.
Correct joint cutting techniques are a must for a long term joint protection system. A common mistake is simply vacuuming out joints in a newly poured construction slab. The main issue is there is already moderate contamination in the joint walls, debris spilled during construction such as paint, mud, chemicals… and more obviously; when the joints are cut during the concrete curing process, it is typically done wet. This allows slurry to build up on the sidewalls which will dry and remain with a future vacuuming being insufficient in removing. Less visible to the naked eye would be the minerals that work their way to the nearest escape from withing the concrete surface, during curing. Mineral deposits form on the inner walls of the joints after a few weeks time in fresh concrete pours and will create a bond breaking atmosphere for polyurea joint fill.
