The job
An open concrete pit in Norfolk County, in September. Broken slats and rubble sat on the rim, and an excavator worked nearby. On Thursday we washed the dark manure line off the base of the walls, a stretch at a time, with our trailer open on the berm. On Saturday the floor went back to bare concrete, one pass at a time.
How we wash a pit: your applicator pumps it down and finishes agitating, and the space is aired out before we start. We park the rig at the pit, hook up to your water and wash the manure line off the walls, then the floor, back to bare concrete.
