The Non-Demolition Grouting Waterproofing Principle: Utilizes nanometer ultrasonic and thermal imaging instruments for precise leak point location, integrates a four-in-one targeted grouting to recreate a waterproof layer. Through high-pressure equipment, the new eco-friendly waterproof material is injected into the gaps, reacts with water, releases carbon dioxide, generates secondary pressure, and the high pressure fills the gaps with grout.
