Leak Plugging Materials

It can be used with low amount of catalyst to adjust the foaming speed according to the actual construction needs in order to achieve the function of stopping water leakage. The reaction with water forms a foaming body, which has the function of stopping water leakage and filling the gap.

Advantages of plugging material

1、Easy to construct, good operability.

2, hydrophobic, not easy to cause residual water in the gap, a long time will destroy the foaming body, resulting in secondary leakage.

3、Good reactivity, react with water about 8-10 minutes foaming completed, 3-7 hours to complete hardening.

4、The product will not shrink, so that the foam does not completely fill the gap, resulting in secondary leakage.

5、The number of foam is enough, it can be as high as 20-30 times, so that it can save the amount of products used and achieve certain effects.

6、Good stability, after opening, it will not deteriorate within the construction time; when it is not opened, the product can be stored for more than half a year without deterioration.

7、Good adhesion with concrete.

8、It can react with acidic or alkaline water or even seawater without affecting the physical and chemical properties of the foaming body.

Application scope and use of plugging material

It can be used in continuous wall, tunnel, box culvert, crack, expansion joint, basement, hairline crack, submerged shield tunnel, window frame, inner and outer wall, reservoir, harbor project, top plate, ground improvement, ring piece water stop, etc.

1、Seal the cracks of dry and wet on the concrete members, and actually fit all contact surfaces.

2、Stopping water leakage.

3、Seal the wet joints.

4、Inject cracks with water pressure type underground water flow, can be used with catalyst to form foam within 3 seconds, and can be completely expanded and solidified within 10 minutes after contact with water.
