Fast-curing urethane and polyurea waterproofing

Fast-curing urethane and polyurea waterproofing

High quality, high performance, high weather resistance! Long-term warranties of 10, 15, and 30 years available, with consistent in-house construction from the base to the finish.

In recent years, the "super fast-curing urethane/polyurea" that is increasingly being adopted on construction sites handles materials from various manufacturers, and we at GSC, who have worked on numerous sites, can respond quickly to diverse environments. The biggest advantage is the speed of curing. Conventional urethane waterproofing materials take about 10 hours to cure, which can lead to issues such as being affected by weather conditions and walking restrictions. However, super fast-curing urethane/polyurea can be touched within about 10 seconds after spraying. Walking is possible in about 15 minutes, allowing for a quick transition to the next phase of construction. It can instantly form waterproof and anti-corrosion coatings, significantly shortening construction time. 【Features】 ■ Significant reduction in construction time ■ High physical properties and durability ■ Versatility ■ Consistent in-house construction *For more details, please refer to the PDF materials or feel free to contact us.

[Information] New technologies related to concrete waterproofing and leakage.

[Information] New technologies related to concrete waterproofing and leakage.

Documents that include "detection of leakage points using ion conductivity" and "prediction of waterproof membrane deterioration."

This document introduces new technologies related to concrete waterproofing and leakage. When water leaks create a water path, the water conducts electricity, which reduces resistance. We conceived a method to detect this and conducted verification tests in actual leaking apartments and buildings, achieving success in all cases. [Contents] ■ Detection of leakage points using ion conductivity ■ Prediction of waterproof membrane deterioration ■ Prediction of rebar corrosion *For more details, please refer to the PDF document or feel free to contact us.
