Spine Rammed Earth Wall - Monaghan Farm, JHB

This home uses a central spine wall made from Rammed Earth to regulate internal temperatures. The beauty of the wall is also visible from outside the house as the walls are parapet type walls, thus they extend beyond the roof line.

The borrow pit clearly visible, where the soil used for the walls was excavated from. Walls were stabilised with Portland Cement to NHBRC specification.

Wall Dimensions: 54m long x 5.5m high x .45m wide.

The construction of the Rammed Earth walls was done by InSynch Sustainable Technologies (Pty) Ltd.

The soil science on this project was challenging due to blinkered view by NHBRC on structural tolerances and crush tests expectancies for Rammed Earth.

Never the less the walls are compliant with the project engineering specification and with NHBRC regulations.

Albeit the cement content is way over what it could have been.

Project completed Feb 2011.
