This site is primarily to outline the works that can be carried out by our company, but also to provide some practical advice on the use of  this unique medium. Rammed Earth or Pise, as it is sometimes known as has been a common form of construction throughout the centuries.   In its simplest form the earth at the site of the proposed building is mixed with water and placed into simple formwork to create the wall.  In some cases additives such a straw or animal dungs were added to improve the properties of the wall.  The walls were regularly rendered with a earth/water render to provide a overall consistant finish. Things in principle have not changed drastically, just been refined to meet todays standards.  The base earth material can still be used directly from the site.  The earth (or crushed limestone) is mixed with cement, water and additives, then compacted into formwork designed to provide a consistant off-form finish that creates a natural rustic finish.  The amount of  cement and additives depends on the earth material type, the location and the type of building being constructed.  The walls are generally sealed for protection from weather and as a binder to reduce dusting.  It is possible to use additives in the mix to provide improved water repelency properties. Terrafirma Rammed Earth is a totally independent Rammed Earth Wall contractor, based in Mandurah West. Australia.   We have been building Rammed Earth walls for almost 15 years, primarily in the metro area and throughout the southwest of the state. Our projects include over 60 residences, community centre, entrance statements, reception desks, feature fences and recently the Piney Lakes Enviromental  Education Centre.  Many of the projects feature in or photo gallery.  Please take the time to view these to see the extent of practical uses of the medium. </p> </body>
