Advanced Pit Within a Pit Liner Extends Service Life

A 1,400-square-foot sulfur pit at a North American refinery required immediate assessment after a partial roof collapse. Following a visual inspection by STRUCTURAL, a full repair was recommended. Because an unscheduled outage creates challenges, however, the owner opted to repair only the collapsed portion and delay the full repair for a scheduled outage.

Electro-Chemical Dewatering System

For building owners and managers, one of the biggest issues is a damp or moldy basement area resulting from water intrusion through cracked concrete slabs and foundation walls. This is evidenced by the fact that structural engineers are often asked by architects and building owners about the cost to design crack-free concrete structures.
