When feasible, batched concrete is typically the best option for repairing intermediate spalls. However, it is often not practical to use batched concrete when working on existing structures or, in some cases, on construction sites.

Proprietary cementitious repair materials can work effectively if applied correctly.

Each step in the repair process (preparation, proportioning, mixing, application, and curing) is critical in the overall performance of the
