When the crack happen on the wall, it’s most likely because of the water leakage problem are happening on the part of the wall. Therefore, it’s important to know what type of material can be used to seal the crack and stop the leakage form happening again. Most of the people in the industry will use the PU Injection method to seal the crack as the Polyurethane have the characteristic of hydrophobic in which it repel against water. Below are some other benefits of PU injection using the Polyurethane:
1. Flexible
The significant advantage of using polyurethane in the PU Injection is because of its flexibility. No matter how the condition of the crack and the weather, polyurethane can still be used as the PU Injection to seal the crack. Even the leaking is still active and the hole of the crack is bigger and wider, polyurethane can still fit in the hole and stop the leaking.
2. Filling Voids
The chemical extension of the polyurethane which normally 5-10 times its usual volume, makes polyurethane suitable as PU Injection at filling voids inside the solid concrete; these voids are commonly imperceptible when you take a look at the wall and usually connected with the porosity of the solid concrete.
3. Quick Affirmation of No Leak
Since water quickens the fixing process for polyurethane, the success of a polyurethane as PU Injection can be affirmed while the injection is in progress. This can be done by flooding the wall during the injection, subsequently giving affirmation that the fixed crack does not spill anymore.
4. Rapid Curing/Fixing
The polyurethane in PU Injection has the ability to cure or fix the crack in a short time. It is important to have this characteristic in stopping the leakage as immediate as possible. When there is a time the waterstopping is urgently needed, then the polyurethane in PU Injection can be used to seal it as soon as possible.
