New proposal for access-challenged sites such as landslide areas! Contributing to initial response measures and labor-saving construction during disasters with three greening methods utilizing drones!
A retaining wall unit boasting reliability. Functionality and beauty showcase the power of design!
Ministry of Land, Infrastructure, Transport and Tourism: Compliant with the Public Building Equipment Construction Standards! Lineup of φ900 and φ1200!
Forming a homogeneous improved ground by injecting quick-setting grout using a double pipe and a special tip device. Construction is environmentally friendly with minimal industrial waste disposal.
A construction method that allows for pipe branching, valve replacement, and expansion work with minimal water drainage! We have newly started a warranty system for the "freezing method"!
Capture of small stones, gravel, and driftwood slipping through a steel slit dam.
Solve the problems associated with road surface restoration work! There is no need to repeatedly perform temporary repairs like in conventional methods!
Standardization and miniaturization of wiring circuit breakers and residual current devices! We are pursuing ease of use!
A pocket-type rockfall protection net designed to pursue "clear safety" through certification and verification by a public third-party organization, featuring high energy absorption.
Segmented construction is possible! A new type of modular bridge that allows for rapid and easy installation.
Ideal for aging bridge construction! Used for seismic reinforcement work, performance restoration work, and also for corroded steel structures.
For the foundation of air conditioning outdoor units, eco-cute heat pump units, and oil tanks, as well as for various piping supports. For securing vending machines.
Ideal for pothole repairs! Can be applied in rainy weather and submerged areas.
