Specialized Products & Services for Sulfur Pits
Reinforced concrete sulfur pits that are below grade are subject to deterioration both internally and externally. High temperatures can cause concrete cracking, allowing ground water to seep through and cause severe deterioration of the concrete. As most pits are inaccessible, these problems can go unnoticed until a unit is shut down for service.
Investigation
STRUCTURAL TECHNOLOGIES has developed industry-leading expertise in the evaluation of sulfur pits. We utilize advanced technologies to assess portions of the pits while they are in operation, and can rapidly provide full condition assessment and root cause analysis when they are taken out of service.
Products & Design Support
We offer many technologies for pit repair, including sulfate resistant concrete repair materials designed specifically for sulfur pit repair. This specialty concrete delivers long-term durability while also curing rapidly to efficiently return sulfur pits to service in short turnarounds. STRUCTURAL TECHNOLOGIES has developed multiple design options to match the level of deterioration and required service life and can rapidly employ them during the same shutdown as the condition assessment.
Turnkey Solutions
When STRUCTURAL TECHNOLOGIES teams with one of our repair and maintenance companies – we offer our turnkey Investigate-Design-Build (IDB) approach to provide a seamless process from initial design through installation with single-source responsibility. This approach is ideally suited for clients looking to perform repair and maintenance during scheduled turnarounds.
