City of Pompano Beach Utilities, Water Treatment Department – Pompano Beach, FL, USA
Structural re-build of steel with an epoxy paste and coated with a urethane-modified epoxy
The City of Pompano Beach consulted with Epoxytec to come up with a solution for the repair of their Water Treatment Plant’s Accelator Clarifier. The severity of the corrosion that has taken place on the steel left the question; can this water clarifier be repaired or will it have to be replaced?
After careful consideration of time, budget and products, the City of Pompano Beach and Epoxytec came to the conclusion that this Accelator Clarifer could indeed be rehabilitated to its original form and better.
Epoxytec helped the Pompano Beach Utilities Department write the specification for the steel rehabilitation of the potable Accelator Water Clarifier as is typical in many instances to provide free support for our clients that are unfamiliar with coating requirements and specification needs. These specifications were designed for steel coating per SSPC and NACE standards.
After the specifications were completed, the next step in the process was selecting a contractor to perform the work. Epoxytec has a network of certified contractors which are also SSPC and NACE certified, that can bid on coating and rehab projects which allows us control quality assurances and serve the warranty without having to inspect the project on a constant basis. This also allows the City of Pompano Beach to go about their daily business and let Epoxytec manage the project for them which is another service provided if requested.
The City of Pompano Beach utilized an active annual, itemized contract that allowed them to price the project per square foot. This process saved time and streamlined the start date earlier to prevent any more deterioration to the steel structure and avoid the spring season (rainy season).
After dry abrasive blasting in accordance to Nace No. 1/ SSPC-SP 5, “White Metal Blast,” an Epoxytec representative inspects the surface, as part of their agreement with City, and the patching and re-building process can begin. The surface preparation crew did a terrific job in getting the steel to where it needed to be in order to properly rehab and coat the steel.
Due to the fact that the steel had many holes and was on the verge of replacement, Epoxytec suggested the use of a structural epoxy paste to patch any holes and re-build any areas that may have weakened from the corrosion. Epoxytec’s epoxy filler is a 1:1 ratio, epoxy paste mix that has a compressive strength of 16,000 psi which bonds to steel extremely well. It’s a smart patching material because you can mix as much or as little as you need depending on the amount of surface needing repair.
