For the long lifespan, prevention of re-deterioration, and regeneration of concrete structures! Construction can be carried out while using the facility!
The "IPH method" involves drilling into the structure and rapidly injecting resin to create airflow, which extracts air from within the cracks and releases it outside, replacing it with resin. This principle allows the resin to fill and penetrate even the finest cracks, curing at ultra-low pressure. As a result, it is a method that can bond and reinforce concrete, integrating and densifying the structure, thereby restoring its strength. 【Features】 ■ High-density filling (replacement of air with resin) ■ Strength recovery and durability improvement ■ Reinforcement against rust and suppression of carbonation ■ Construction can be carried out while the facility is in use *For more details, please refer to the PDF document or feel free to contact us.
