Whenever I have a concrete opening to reinstate, I call Core Seal. At our Sureway Gardens project, we had hundreds if not more than one thousand core holes to fill. Our normal labor-intensive method of using a lift on the underside of the slab, installing rebar, mounting material to contain the concrete, then filling the hole, and eventually stripping the no longer needed material is time-consuming and cost-intensive. Core Seal’s innovative single-sided system gets the job done from the top of the slab without the need of expensive equipment in far less time. Core Seal, when asked, has provided Ellis Don with quick, professional and cost-effective service.
