For repairs and reinforcement of concrete and mortar in all fields! Long-term durability enhancement system.
The "IPH System (Internal Pressure Filling Joint Reinforcement Method)" is one of the automatic low-pressure resin injection methods widely used for the restoration of concrete structures damaged by earthquakes and for the repair and renovation of existing structures. By drilling a hole for the injector installation and injecting high-flow resin at low pressure from within the concrete, it is possible to achieve high-precision filling, akin to ensuring that moisture and nutrients reach all the veins of a plant's leaves. By diffusing the resin into a spherical shape, the injection density around the rebar increases, providing a rust prevention enhancement effect. 【Features】 - The epoxy resin for injection is highly fluid, allowing for more natural injection by utilizing capillary action. - Injection and filling into fine cracks within the structure can be achieved for widths down to 0.01 mm. - The filling effect at the ends of fine cracks improves the durability of the components beyond the design strength at the time of new construction. - Due to the filling effect in fine areas, it is expected to be effective not only for structures but also as a waterproofing method for buildings. - The components of the cement paste designed to prevent resin leakage penetrate reliably to the internal rebar. *For more details, please refer to the PDF document or feel free to contact us.
