Good cost-effectiveness: 

The performance of Water Swelling Polyurethane Sealant is better than that of traditional construction joint waterproofing materials and is moderately priced.

Scope of application:

Polyurethane water-swelling waterproofing glue is widely used in waterproofing concrete construction joints and anti-leakage of various embedded components. Its unique expansion and waterproofing properties make it an indispensable waterproof material in the fields of construction, water conservancy, transportation, etc.

Precautions for use:

Before use, check whether the packaging is intact and whether the product is expired or deteriorated. During construction, the requirements in the product manual should be followed to ensure the quality of construction. After construction, care should be taken to protect the construction surface to avoid damage by external forces before it is fully cured.
