Application Situation
Secondary containment area where fatty acids were stored
Application Method
Old surfaces were pressure washed and any loose material was removed. The eroded concrete surfaces were resurfaced using Belzona 4154 mixed with sand. The surfaces were built up to original spec (up to 1.5 inches in some areas) and new gradients were created to ensure correct drainage. Belzona 4181 was used to repair the concrete directly under the steam lines. Two coats of Belzona 5811 were applied on the rebuilt surfaces. The application area was approximately 800 square feet.
Belzona Facts
The only other option was to have new concrete structures made. The repair took a total of 5 days. Belzona was chosen due to previous KHIA's showing containment repairs and short repair time.
