Chemical-Resistant Coating for Precast Concrete Components
In the water industry, safeguarding precast concrete components from corrosive substances is essential for maintaining infrastructure integrity. A recent project in Leicestershire showcased Total Specialist Maintenance’s (TSM) expertise in applying a chemical-resistant coating for a water company, ensuring timely delivery and long-lasting durability.
The Challenge
The client required precast concrete components to be coated with a hydrogen sulfide (H2S) resistant coating before their arrival on site. Key challenges included:
- Preparing Concrete Surfaces: Ensuring that the concrete surfaces were adequately prepared for effective coating adhesion was crucial for the success of the project.
- Meeting Project Timelines: Adhering to strict project timelines was essential to facilitate smooth program delivery and avoid delays in installation.
Why Chemical Resistant Coating?
To combat the hazardous nature of H2S, TSM recognised the necessity for a specialised coating. This approach offered several advantages:
- Protection Against Chemical Degradation: The coating provided a robust barrier against corrosive agents, significantly enhancing the lifespan of the concrete components.
- Alignment with Project Schedule: By applying the coating before the components arrived on site, TSM ensured that the installation could proceed efficiently, keeping the project on track.
The Solution: Efficient Coating Application
TSM implemented a streamlined process that included:
- Mechanical Preparation: Preparing the substrate involved thorough cleaning and surface profiling to create a mechanical key. This step was essential to ensure optimal adhesion for the coating, preventing future delamination.
- Coating Application: Trowel applying two coats of MC Building Chemicals Ombran CPS hybrid silicate chemical-resistant coating ensured comprehensive protection against H2S and other corrosive substances. This hybrid silicate coating provides excellent durability and flexibility, allowing it to withstand the harsh conditions typically found in water treatment environments.
- Quality Control: Throughout the application process, TSM conducted rigorous quality checks to ensure that the coating was applied uniformly and met all required specifications.
This methodical approach ensured that the precast components were adequately prepared and ready for installation upon arrival, minimising downtime and maximising efficiency.
Project Management Excellence
TSM’s project management team effectively coordinated the coating application process, ensuring that all activities adhered to the planned schedule. The successful execution of this project not only met the client’s expectations but also reinforced TSM’s reputation as a leader in industrial maintenance solutions.
Environmental Considerations
Given the nature of the water industry, TSM prioritised the use of environmentally friendly materials during the coating process. The selected chemical-resistant coating was formulated to minimise environmental impact while providing superior protection for the precast components.
