The "Super Hozen Method" is a construction technique aimed at extending the lifespan of bridge deck slabs. The construction involves securely fastening mesh rebar to the underside of the existing deck slab using tapered T-type anchors. It alleviates vibrations and impacts on the deck slab, and after applying a thick layer of polymer cement mortar (Hozen material #10), low-pressure epoxy resin injection is performed to completely integrate with the existing deck slab. This method allows for construction without damaging the structure while vehicles are in operation, ensuring a reliable rejuvenation through three stages of lifespan extension measures. 【Features】 - No restrictions on vehicle passage - Construction possible without damage while vehicles are in operation - Reliable rejuvenation through three stages of lifespan extension measures *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The "PA Joint" is a buried expansion device that does not require secondary water stopping, featuring seismic resistance due to its ability to expand and contract in all directions by 360 degrees. It does not experience the fluidity and cracking typical of buried joints, and it is robust with high durability (over 15 years). It performs better against temperature fluctuations and can accommodate a maximum expansion of up to 100mm. This significantly improves the durability issues associated with conventional buried joints, suppresses the occurrence of subsidence and cracking due to fluidity, and ensures the safety of passing vehicles. 【Features】 ■ High durability ■ Zero displacement after over 63,000 rotations in wheel tracking tests ■ Average wear of 0.05mm in labeling test results (Japan Road Construction Association) ■ Can be constructed with the same material for the ground cover, allowing for seamless water stopping ■ Exhibits the same expansion and contraction performance in all 360 degrees *For more details, please refer to the PDF materials or feel free to contact us.

• Bridge Materials

The "MM-JOINT・DSII type" is a simple and highly durable bridge expansion joint composed of a special binder, DS aggregate as the main material, secondary water stop devices, gap plates, and pins. Since it is an asphalt-based expansion joint similar to the existing coating, it provides a comfortable experience during passage, suppressing noise and vibration for good drivability. Compared to conventional butt joints, the construction cost is lower, and partial repairs with the same material can be easily performed regardless of the extent of damage, resulting in significantly reduced running costs. 【Features】 ■ Excellent economy and durability ■ Comfortable drivability ■ High waterproofing performance ■ Easy construction *For more details, please refer to the PDF document or feel free to contact us.

• Bridge Materials

"ACE-PATCH" is a special high-polymer cold mix material made by mixing a resin-containing binder with selected aggregates. No preparation such as viscous coatings or adhesives is required, and it can be opened immediately after repair even on roads with heavy traffic, where it is compacted by passing vehicles, completing the repair. Additionally, due to the effect of anti-stripping agents, this patch material exhibits strong bonding power and increases curing strength with prolonged compaction. 【Features】 ■ Achieves quick installation ■ Excellent abrasion resistance ■ Outstanding durability ■ All-weather compatible (installation is possible during rain and snow) ■ Long-term storage is possible *For more details, please refer to the PDF document or feel free to contact us.

• Reinforcement and repair materials

"MK Crete 45(R)" is a concrete repair material that allows for repairs to be completed in just 15 minutes. Due to its non-shrink properties, it is less likely to crack during curing and exhibits high strength even in high and low temperatures. Additionally, since the product is contained in a sealed can, it can be stored for a long time as long as the lid is properly closed. 【Features】 ■ Curing takes only 1 hour ■ No preparation needed ■ No shrinkage, no cracks ■ Exceptional strength ■ Long-term storage possible *For more details, please download the PDF or feel free to contact us.
