CV spray method <Seamless waterproofing for underground structures>

Overcoming underground conditions to achieve ideal external waterproofing! Low-cost construction method for reducing construction time and costs.

The high polymer urethane rubber film formation technology using the super-fast curing spray-up system allows for the coating of structures with high performance, achieving reliable waterproofing and protective effects. This is the "CV Spray Method" from Sika Japan. The pre-waterproofing construction can be applied directly to retaining walls such as SMW without creating a substrate, thus reducing the time and cost required for waterproofing substrates. Additionally, the post-waterproofing construction adheres firmly to the structure, eliminating the need for protective materials during backfilling. With a mechanically managed construction system, a consistent amount of material is supplied, ensuring uniform and high-quality film properties that are not affected by external temperatures or working conditions. 【Features】 ■ Low-cost method that reduces construction time and costs ■ Seamless complete waterproofing for complex shapes ■ Uniform, high-performance membrane waterproofing ■ Excellent durability *For more details, please download the PDF or feel free to contact us.
