How to Prevent Cracks in Grouting Materials?

Prevention:

When preparing the grouting material, strictly follow the instructions to add water, reduce the porosity, and thereby minimize shrinkage and enhance the grouting material's crack resistance.

Before grouting material is poured, the base and formwork should be thoroughly soaked with water.

3) When working under hot, cold, or high-wind weather conditions, it is crucial to immediately water cure the grouting material after pouring. To maintain its moisture, the curing process should be conducted for large-scale grouting material after each section is poured. Strengthening the surface smoothing and curing efforts is essential during the curing stage.

4) The curing of grouting material can be done using surface-sprayed chlorinated paraffin emulsion curing agent, or by covering with straw bags, plastic films, and other methods. When fine cracks are found on the surface, they should be pressed and sealed immediately before covering and curing.
