Construction is possible in places where machinery cannot enter! A residential foundation that can withstand 50 to 100 years of use.
The "Naro Power Method" is a ground improvement technique that involves driving numerous thin steel pipes down to the supporting ground to support residential buildings. All equipment is designed to be operated manually, allowing work to be conducted even in narrow spaces. After installation, a sampling load test is conducted to confirm whether the designed ground bearing capacity has been achieved, and if any deficiency in ground bearing capacity is observed, additional work will be carried out. By ensuring reliable quality control in this manner, we provide residential foundations that can withstand use for 50 to 100 years. 【Features】 ■ Recommended for the restoration of old houses ■ Sampling load tests are conducted ■ Suitable for narrow spaces where machinery cannot enter ■ Durability of 50 to 100 years *For more details, please refer to the PDF materials or feel free to contact us.
