Buttress Piling Retaining Wall System

This system was designed and patented by CSM Group’s senior structural engineer Edgar Agda to overcome the situation when the adjacent neighbouring land owner does not consent to rock or soil nail anchoring systems being installed underneath their property.

This system is used as the bulk excavation retaining wall where deep underground basements are required in a building.

Buttress piling is a system whereby a piered wall is restrained by inserting additional piers perpendicular to the wall (in towards the building). That is, away from the adjacent lot boundary in order to restrain the main wall from sliding, overturning and deflecting due to soil, pore pressure and other applied loads.

• The retaining wall system relies on the bearing capacity of material and cohesion between the piers in order to enable three dimensional restraining actions to occur.
• This system has already been installed in 23 building sites, where the developers were grateful that their developments could proceed even though they didn’t have the adjacent land owners’ consent.
• The advantages of this unique system include:
• Proprietary System concrete Panel wall construction system that works via an internal propping system ie, buttress piling, without external rock anchoring
• No authorisations required from adjacent landowners
• Less risk involved in construction
• Shorter construction duration
• Cheaper construction costs

This particular buttress piling system shown in the photos is applicable for clay / sandy soil stratas, however where the site is mostly rock we utilise a system named buttress ‘framing’.
