Asphalt mats that protect harbors and coastlines from disasters.
The asphalt mat is formed by embedding reinforcing core materials, lifting wire ropes, and lifting fittings within asphalt aggregate. It is widely used in hydraulic structures from rivers and coastlines to oceans, and can also be used for prevention of permeability, slope protection, water cutoff works, and anchoring measures. 【Main Uses】 ■ For Increasing Friction - By installing it between caissons, block walls, etc., and the riprap, it is possible to use a friction coefficient of 0.8, allowing for a reduction in cross-sectional width. ■ For Erosion Prevention - It can bend into the slopes of erosion holes that occur on the front and back surfaces of riprap mounds and wave-dissipating blocks in ports and coastal structures, stopping the progression of erosion. ■ For Preventing Suction - It can be laid on the bottom surfaces of riprap mounds and wave-dissipating blocks to prevent the suction of bottom materials (sand). - It can be laid on the back side of riprap mounds for reclaimed shorelines to prevent the loss of backfill materials due to suction. *For more details, please download the PDF or contact us.

Company information
Our company is engaged in civil engineering projects in marine, coastal, and inland areas. In particular, we utilize unique technologies such as asphalt mats and underwater non-segregating concrete for caisson friction enhancement, shore protection against scour, waterproofing and water-stopping works for marine pollution prevention, and renewal of marine structures. Additionally, we conduct various geological surveys, underground facility investigations, underground facility and magnetic surveys, cavity investigations, unexploded ordnance surveys, various measurements, marine surveys, testing measurements, and hydraulic model experiments. We also carry out research, planning, design, technical guidance, and other engineering and consulting services related to these construction projects.
