Case Studies

Issue Concrete damage due to a chemical attack, embedded metal corrosion, harsh environment and molten sulfur service. Cause Water intrusion creates sulfurous acid that attacks the cementitious paste of concrete, causing a chemical attack and degradation of the structural elements of the below ground storage pit. Chemical attack and embedded metal corrosion affects the structural…

Issue Concrete damage due to a chemical attack and erosion from a mechanical process Cause Due to the nature of the process, the chemical attack caused degradation of the concrete substrate and paste. Mechanical erosion from the mixing process eroded the structural floor and walls in the mixing chambers. Constructability The sump was isolated, blinded…

Issue Concrete damage due to chemical attack, harsh environment, and service of molten sulfur. Cause Water intrusion causes sulfurous acid that attacks the cementitious paste of concrete, causing a chemical attack and degradation of the structural elements below the ground storage pit along with embedded metal corrosion of the reinforcing steel that comprises structural integrity.…

Issue Concrete damage due to embedded metal corrosion and mechanical abuse by barges and container ships. Cause Embedded metal corrosion due to location on major Gulf Coast river as well as repeated mechanical abuse from barges and ships that utilize the dock on a routine basis. Constructibility Due to limited access associated with the dock…

Issue Client had an emergency with another contractor who was to perform a concrete rehabilitation of a sulfur pit during a critical outage. Béton was called in to consult and immediately mobilize to keep the project on schedule and cost. Due to the responsiveness and experience, Béton was awarded the contract and over took the…
