A tuck mill, also known as a fulling mill, was used to finish woven woollen cloth: waterpower drove wooden hammers that pounded the fabric in water, shrinking and compressing the fibres to produce a denser, more weatherproof textile. It was an industrial process that once shaped rural economies across Ireland, yet the physical evidence for it has largely vanished from the landscape. At Ballinteosig, one west-facing wall, running about four metres north to south, survives alongside a wheel-pit some 2.4 metres wide, the channel through which water was directed onto the mill wheel itself.

The site appears on the Ordnance Survey six-inch map of 1842, which gives some indication of when it was still a recognised feature of the local landscape. At some point after the mill fell out of use, a residential house was built on or around the same footprint, incorporating the old west wall rather than demolishing it. That house has since been abandoned and is now overgrown, leaving a layered ruin in which the domestic and the industrial have merged into something harder to read at a glance. The wheel-pit runs along the external face of the surviving wall, hinting at the original arrangement of the machinery within.
