SMW method was invented in Japan in 1970s and transmitted in Europe and US gradually. From 1990s, it is brought to China and until now, it has become the most popular and safety method to form retaining walls in the field of building basement, subways, hydro projects in East Asia regional market, comprising Japan, Korea, and China.

SMW is the short-term for Soil Mixing Wall, the method so-called Colonnade Style Soil Cementation Wall, which is a soil consolidation method used by multiple shaft earth auger as per the following process:
  • Trench by excavator with 2-3m.
  • Drill into the requested depth.
  • Inject the cement slurry as per the soil condition and mixing with original underground soil, while lifting the Earth Auger.
  • Form one section of the wall of soil and cement mixed.
  • Finish another new section of wall nearby as the same way in the same line.
  • Return and form the wall between the previous two sections with overlap
  • According to the job request to insert the H beam or other shape of sheet pile for stress reinforcement structure.
  • After the solidified, it forms a stressed, retaining, underground wall for containment or water resistance purpose.
The SMW method features Good water resistance ability, Depth for drilling, Excellent Soil resistance function, Environment-friendly, cost effective, no vibration and low noise compared with Sheet vibro piling for retaining. Hence, the method is widely applied in Containment and retaining wall for deep basement excavation; Water resistance/ Retaining Wall for canal and hydro project; Wall resistance under the dam; and Protection from collapse underground pipe or tunnel.
