Concrete Polish Industry, "Black Eye".
On most remodel's that the floors are to be polished concrete, trenches must be cut to accommodate new conduits or plumbing. The trenches must be filled. The concrete pour-back NEVER matches the field of the rest of the floor.
They have become acceptable EYE-SORES in the polish concrete industry.
Even if the concrete pour-back is left 1/2" down to be capped off with a Polish concrete overlayment, the overlayment NEVER matches the field of the floor. To rectify, a polish overlay is often the very expensive answer. Now there is a very reasonable and easy fix for the the BLACK EYE trenches.
Lets compare on 600 sq ft room with 12" x 25' of trench pour-back running through the center of the area.
Overlayment; $2,100.00 in material. $7,200.00 to $10,000.00 total cost of installation. Extra 3 days added to project schedule.
Match Patch Pro Part C overlay $200.00 in material. $750.00 - $850.00 total cost of installation. Matching results @ 10% total cost of an overlay. Zero extra time added to project schedule.
