Here’s a look back on a good project in Limestone, Maine.
There's some history here. Back in 1951, company founder Herbert E. Sargent had a stone-crushing contract at what was then Loring Air Force Base. Decades later, his grandson, Herb R. Sargent, worked jobs at that same site.
Last November, Sargent crews were back at Loring, this time on sewer replacement for the Loring Development Authority of Maine. The job swapped out 10,000 feet of line and 40 manholes. Old clay pipe and brick manholes came out, PVC sewers and concrete manholes went in, with some trenches running 18 feet deep. Crews worked around an active broccoli packaging plant and kept every gallon of groundwater on site, dewatering trenches and pumping it right back into the ground.
About 20 employee-owners worked this job alongside local suppliers Trombley Industries, Inc. and Soderberg Construction Company. Crews pushed hard through the fall to beat the ground freeze, knowing winter in Limestone would shut things down until spring.
