Challenges for Quality & Safety Control

Safety control is, all the time, the most prioritized and important task for construction industry.
All the construction sites maintain safety-conscious mind in daily work, and void-slab products are high quality products with patent in the Diamond Void-slab construction method. Furthermore, those void-slab products were approved by Japan Construction Total Test Institute Foundation for flexural property and shear performance, and the third party institute tested 2 hour-fire proof.

Spray destruction test on CB block and brick

Daisun are conducting research and development for coating paints and anti-earthquake structure in collaboration with Tokyo University of Science.

Polyurea resin is superior to polyurethane resin in all aspects such as water resistance, corrosion resistance, abrasion resistance, and chemical resistance because it has strong bonding strength and does not hydrolyze.
Daisun is not only engaged in the construction and sale of polyurea resin, but also in the development of new paints that make use of its features. We conducted a verification experiment and obtained results that are effective in improving the damping performance of buildings etc. and preventing the collapse of block walls and brick masonry.
In addition, with the Tokyo University of Science, we are promoting research and development for creating a house resistant to disasters, such as the “Air Assumption System,” which blocks the conduction of earthquakes by floating the house with the force of air.
