Crack treatment used by cold pourable crack filler

Time:2018/08/01 Hits:

Why should extend crack before injecting pourable filler when crack width is less than 3mm? Why not to inject filler directly?

1. The cold pourable crack filler is relatively thick. The fluidity is not well compared with water, so it is not injected into the cracks smoothly.

2. The diameter of the nozzle on the plastic bag is 3 mm, larger than the cracks width

3. It is not easy to inject due to the inherent surface tension of the liquid (like water droplets on lotus leaves, the inherent surface tension of the liquid).
