Application Situation
Badly damaged concrete in a caustic and hydrochloric acid secondary containment area at a chemical plant. Both caustic and hydrochloric acid are at 10% concentration and at ambient temperature.
Application Method
The application was carried out in accordance with Belzona System Leaflets TCC-9 and TCC-15. Damaged and loose concrete was removed and the entire area was high pressure water washed. PH testing was carried out and the area verified neutral after washing. When dry the eroded vertical surfaces of the tank and pump support bases were rebuilt with Belzona 4141 (Magma-Build). The deeply eroded areas of the concrete floor were filled to within approximately 1/4" of the final grade using Belzona 4154 (Bulkfill Resin) and sand. The final grade required for proper drainage was achieved using Belzona 4131 (Magma-Screed). The entire area was protected with Belzona 5811 with a light broadcast coat of aggregate for slip-resistance.
Belzona Facts
Belzona products were chosen for their proven durability and chemical resistance for the long term protection of secondary chemical containment areas.
