BuildingDesignExpert Podcast – Unstabilised Rammed Earth pt.1
This is part 2 and the final part of my interview with Roland Keable and we are talking “Unstabilised Rammed Earth wall construction”. How do you ‘stabilise’ Rammed Earth Wall construction? What would you call a rammed earth wall matrix that contained cement? and what are the processes involved during the design and construction process? To find out the answers to these questions you must listen to the podcast.
This podcast is approximately 36 minutes long

The use of compacted earth as a building material is common in many countries, but despite its apparent abundance, use of earth as a building material remains relatively rare in the UK. As well as looking at the properties of rammed earth, or pise, this programme asks whether concrete should be added as a stabiliser, the issue of cost, and along the way we look at some high-profile failures and successes.
Key learning points:
- Explains the changes and the reason for the changes… and when they come into force
- What are the properties of rammed earth walls and how are they constructed
- What codes and standards are there for rammed earth construction?
- Why is rammed earth construction comparatively expensive?
- What causes some rammed earth walls to fail?
About the contributors
Rowland Keable, founder Rammed Earth Consulting CIC has been building with rammed earth since 1985, across Africa and Australia, and in the UK since 1999 including walls at The Eden Project and the UK’s tallest at the Centre for Alternative Technology in Wales.
As well as building, he has co-authored a couple of books and a BRE guide for rammed earth construction, taught in schools of architecture, engineering and surveying, and run workshops for a wide range of people.
Pat Borer, architect with over 35 years’ experience in designing and constructing ‘green’ buildings. He has been closely involved with the Centre for Alternative Technology in Wales with the design and development of ultra-low energy buildings, passive and active solar heating systems, photovoltaic roofs, benign building materials and technologies, co-operative ways of building and healthy internal environments.
Elsewhere in the country, Pat has been developing ecological timber frame designs for the self-build housing sector.
