ADD Concrete LLC is a concrete contractor. On its own website the company says concrete work has to line up with more than a drawing, and that access, grade, excavation, reinforcement and pour timing all shape how a job comes together. Its Connecticut home improvement contractor registration, HIC.0016440, held by ADD CONCRETE LLC, is inactive on the state registry due to non-renewal of the credential.
