Cost Reduction. It is possible to reduce cost in case of on the soft ground or having difficult construction condition. Reduction of Construction Duration. Cutting down labor cost and construction dulation are reduced due to no need of curing after work. Unnecessary of Concrete. It is eco-frindly construction method not using concrete. Unnecessary of Disposal of Surplus Soil. Disposal of surplus soil is not required due to not using excavating work. Possible to Reusing. It is possible to install the other place or demolish because it can be pull out by back lashing easily. Optimal the Soft Ground. Bearing capacity is increased on the soft ground to vertical direction and it can makes foundation on the difficult place not possible with existing methode. Non-Vibration Work. According to hydraulic auger and circulation press-in, non-vibration, anti-noise work is possible and makes construction condition simple. Action to Underground Utilities. Design avoiding underground utilities and eccentric structure makes the work obstruction over. Action to All Construction Condition. Narrow construction place including not possible, noise, non-vibration soft ground, out of transporation(only allowed manual carriage). All-weather construction.
