Kaufman Products Is Used For Concrete Step Repair & Resurfacing

When a local church took over a new building, many improvements were needed in order to bring the building to code compliance. One of the larger issues that needed to be addressed were the concrete steps leading to the building entrance. Over the years, water infiltrated through cracks in the concrete steps causing concrete spalling and exposing some of the reinforcing steel.

Areas were chipped and prepped, and that process exposed some steel which evaluated and determined to be sound. SurePoxy HM epoxy was mixed and applied on the reinforcing steel for future protection. Additionally, it was applied to the surrounding concrete to act as a bonding agent. The concrete was then hand patched using our latex modified mortar designed for vertical/overhead applications from 3” down to 1/8” called Patchwell V/O and was finished to match the existing concrete.

On the exterior, the cracks were cut and chased to open them. The spalled areas were squared, and loose deteriorated concrete was removed. The cracks were flooded with SurePoxy VLM LV epoxy and allowed to gravity seal with a very-low-modulus epoxy resin. Spalled areas were painted with SurePoxy HM epoxy as a bonding agent, and the areas were patched with Patchwell Deep our latex modified repair mortar designed for horizontal applications from 2” down to ¼” without aggregate addition. After repairs were completed, joints were cut into the steps to allow for necessary expansion.

A previously installed topping on the landing became unbonded over time and was removed. Cracks in the underlying substrate were cut and structurally repaired with our super low-viscosity injection resin called SurePoxy HM SLV. Afterwards, our gray, 100% solids epoxy bonding agent called SurePoxy 110 was mixed and applied. While tacky Patchwell Deep was mixed, applied, and allowed to cure.

After all exterior concrete repairs were properly cured, a resurfacing system was installed on the steps and landing. The system consisted of a prime coat of SurePoxy VLM LV, a second coat of the SurePoxy VLM LV, and for skid-resistance a broadcast of SurePoxy Mortar Aggregate at a rate of ¾ to 1 pound per square foot which was then allowed to cure. SurePoxy VLM LV was chosen due to its very-low-modulus of elasticity. Excess aggregate was removed and a surface seal of our non-yellowing aliphatic urethane SureKote 100U (2 coats) was applied and cured.

The finished result, which brought the church into code compliance without having to do an extensive rebuild to the front entrance steps, now offers the congregation a place to worship for years to come.
