Introduction to Construction Method: "Epo Method"

Introduction to Construction Method: "Epo Method"

We will easily resolve manhole troubles.

The "Epo Method" is a technique that smoothly cuts out manholes that have started to make noise every time a vehicle passes over them using a hydraulic cutter, and finishes them with epoxy resin concrete material, making them three times stronger than asphalt.

Construction method "IPH Method (Internal Pressure Filling Joint Reinforcement)"

Construction method "IPH Method (Internal Pressure Filling Joint Reinforcement)"

Technology to achieve the "long lifespan" of damaged concrete structures!

The "IPH method" is a technology that achieves "strength recovery" and "extended lifespan" for concrete structures that have deteriorated due to aging or earthquakes. By replacing the air inside the concrete with injected resin, it can fill even fine cracks with high density and depth. Not only does it enhance the bond strength between rebar and concrete, but it also provides a high anti-corrosion effect. The method has received technical evaluation from the Japan Society of Civil Engineers and obtained a patent as a construction method in 2012. 【Features】 ■ Replacement of air and resin ■ High-density filling ■ Strength recovery and durability improvement ■ Rebar anti-corrosion and neutralization suppression ■ Improved cost-effectiveness and environmental measures *For more details, please download the PDF or feel free to contact us.

The "Round Separator Angle" allows for the installation of separators at a constant length by attaching it parallel to the concrete formwork surface. After the rebar assembly, the separators can be installed. This eliminates overlap with rebar workers, formwork workers, and welders, leading to a reduction in construction time and overall costs. 【Features】 ■ Screw holes are cut at 75mm intervals along the entire length of the angle ■ Separators can be installed at any desired position ■ Can be used for positioning rebar by rebar workers ■ Eliminates overlap with rebar workers, formwork workers, and welders, resulting in reduced construction time and overall costs ■ Installation work is also available *For more details, please refer to the PDF document or feel free to contact us.
