New Grinder Pit for Sabert Corporation, Sayreville, New Jersey. Sabert expanded production of stamped plastic food grade bowls and similar products required a new rectangular pit (14' X 22') set eight foot below finished floor and due to space constraints, had to be situated near the intersection of two building additions. As a result, the pit potentially undermined two column footings and two masonry walls. To complicate matters, the excavation, shoring and concrete placement work had to be conducted without compromising a clean facility. Did we mention the high water table?   We developed an economical and constructible solution while protecting both the existing foundations and the workers below grade. We specified a step-by-step process utilizing 3X6 sheeting, two layers of steel compression rings to hold the sheeting in position and a multi-stage concrete pouring schedule. Keeping the nearby area clean was accomplished by the contractor by erecting plastic sheeting light gage metal walls and power venting the space directly outside while maintaining negative air pressure. To everyone's delight, the project was completed on time and on budget.
