Broken Step Repair with Concrete Mender™

Vertical concrete repair with Roadware 10 Minute Concrete Mender™ is simple if you use a few basic techniques. The following is a repair to a spalled out concrete step. As with any concrete repair, the first step is to remove any loose concrete with a chisel and clean the repair area with a wire brush and a shop vacuum. Remove all dust, dirt and loose materials. Any moisture on the concrete surfaces should be allowed to dry. On occasion, I will use a heat gun to dry the concrete.

Warehouse Floor Repairs in the Dominican Republic.

Franklin Gutierrez in the Dominican Republic is using Roadware 10 Minute Concrete Mender™  to repair multiple spalls in a warehouse floor that were causing damaged forklifts and damaged backs.

“We did 87 repairs for this client, it is a tin can production plant, they work 24/7 so there was no time to close areas for repairs , also lots of equipment very sensible to dust in the air. The major problem was that those small holes were damaging the wheels of the forklifts, damaging the back of the operators and creating possible dangerous situations for the forklift operators, because they manage very heavy loads and even a small hole could make it unstable.
We did all in two days and the client is very very happy, the problems were solved and there was no interruption for them.
This is a big plant that produces for the local market and export, its called Troquedom.” 

Loose materials are removed from the spall.
