Zypex method

The durability of concrete has dramatically improved! [NETIS registered] We are exploring new possibilities for concrete that continues to regenerate semi-permanently.

Zypex is a concrete modification material that densifies the structure by promoting the growth of cement crystals in defects such as voids and cracks within the concrete, thereby blocking deterioration factors like water and enhancing waterproof performance to improve the durability of the structure. ■Mechanism of Concrete Densification■ The mechanism of densification by Zypex involves mixing concentrated powder with a specified amount of clean water to create a paste, which is then applied or sprayed onto the surface of the concrete. This allows catalytic compounds to penetrate deep into the concrete, promoting the growth of new cement crystals at the capillary voids and crack interfaces, thereby densifying the concrete structure itself. The depth of modification through crystallization can vary depending on the concrete conditions, but it can extend to over 30 cm in a moist environment.

Non-vibration low-noise static compaction sand pile method 'KS-EGG-SE method'

Smooth construction even in areas close to urban areas and structures by reducing vibration and noise! NETIS number: KTK-180001-A

The "KS-EGG-SE Method" is a ground improvement technique for soft ground that achieves reduced vibration and noise, utilizing a non-vibrating, low-noise sand compaction pile method (static compaction sand pile method). In conventional sand compaction pile methods (vibrating SCP method), the impact of vibration and noise on surrounding areas is significant, particularly in urban areas or regions close to structures, which can hinder smooth construction execution. The "KS-EGG-SE Method" is designed to address such situations. In sandy ground, it serves as a countermeasure against liquefaction, while in cohesive soil, it is one of the density-increasing methods that enhance ground stability by increasing bearing capacity. 【Features】 - Non-vibrating, low noise… Smaller compared to vibrating SCP methods - Assurance of quality… Higher compaction effect on the ground. Comparable improvement effect to vibrating methods during construction - High construction capability… Can penetrate even with some obstacles or hard layers. Cost-effective and rapid construction is possible as pre-excavation is not required - Use of recycled materials… Effective utilization of materials such as glass sand, recycled crushed stone, and slag as pile materials For more details, please refer to the PDF document or feel free to contact us.

Ground investigation option "Surface Wave Exploration Method"

Now, earthquake measures start from the ground! We can calculate how much the investigation site will shake.

The damage caused by earthquakes varies depending on the magnitude of the earthquake and the hardness of the ground. During the Great East Japan Earthquake in 2011, even areas far from the epicenter experienced damage to buildings, including structural damage and collapses. One of the factors contributing to this is believed to be the hardness of the ground. The magnitude of an earthquake is influenced by the ground strength and layer thickness as the earthquake occurs in an engineering foundation (where seismic waves travel at over 400 m/s) and propagates through the ground. In other words, if the ground is soft and the layer thickness is large, the ground shaking will be more intense. The investigation of ground shaking susceptibility calculates the necessary coefficient Co to determine seismic forces based on the results of ground surveys conducted through "surface wave exploration." It is possible to estimate seismic forces taking into account the ground conditions of the survey site.
