A Two Foot Flood Cut and an Epoxy Floor in a Westport Basement

A flood cut is a horizontal cut made at a fixed height all the way around a room, taking every wall surface below that line. On this Westport basement the cut ran 294 linear feet at a height of two feet. The advantage of working to a set line rather than chasing damage is certainty: nothing wet is left behind a wall because everything below the line is gone. The cost of it is material that was never affected coming out alongside material that was.

It is a deliberate trade, and it suits a basement where the water arrived at floor level and moved along the whole perimeter rather than pooling in one place. Above and around the cut, 1,516 square feet of horizontal and vertical surfaces were cleaned as a single environmental pass. That figure is the one that describes the real size of this job. The demolition is a strip two feet high; the cleaning is the whole room. Containment ran to 120 square feet with two zipper doors and four 24 hour negative air periods held the space under negative pressure throughout.

The decision worth explaining is the last one. 170 square feet of the concrete floor was painted with two coats of epoxy. Bare concrete in a basement is porous. It takes on moisture from below, it holds whatever is spilled on it, and it cannot really be cleaned, only wiped. An epoxy coating converts that surface into something sealed and washable, which changes how the room behaves the next time water appears. It is the only part of this scope that is an improvement rather than a restoration, and it is the part most likely to matter in five years.

What was not sold: no insulation was removed, no antimicrobial agent or coating was applied, no drywall was replaced, and no testing or clearance was performed. The basement was handed back cut, cleaned and with a finished floor, but not rebuilt.
