Concrete Hydro says it has been working on concrete out of Manchester since 1969, when it started as Associated Concrete Coatings — 57 years, by the company's count. The trade is narrow and deep: concrete coatings, waterproofing and concrete repair. Most of that work goes on large commercial, institutional and industrial buildings, with the occasional complex single-home project alongside it. The company states membership in Associated Builders and Contractors and in the International Concrete Repair Institute. For a homeowner, this is the call when the concrete itself is the problem — a foundation wall letting water through, a deteriorating slab, a basement or garage floor that needs coating — rather than a general basement finish. Ask first whether they take work at your scale, then get the repair method and the warranty in writing.
