One thing noticeable with a rammed earth is the fault lines on the exterior side. These lines would show the points where the earth was rammed to form the home. The colors would also be obvious. Some parts would be darker than others. Most homeowners do not hide the discoloration or the lines though they can be covered with stucco or tiles. Owners of rammed earth homes do not worry about aesthetics because the result of the construction would in itself exude a unique beauty on its own.
The walls of the house would probably be 18 to 24 inches (46 cm and 61 cm) in thickness. The thick walls add to the uniqueness of the house. Thick walls provide silence as sounds coming from the outside may not penetrate through the thick walls. They also provide warmth and comfort. Many homeowners feel security within the thick wall
There are other benefits of having a rammed earth home, namely:
- The thick walls of the home provide excellent thermal mass. During summer or warm days, the home will be nice and cool just like when you are inside an underground cave. At nighttime, the home will be warm as the weather outside may turn cold. This is due to the thermal flywheel effect. The walls hold on to the warmth and expel this about 12 hours later.
- Due to the cooling / heating effect, homeowners do not need an air conditioning unit or a heating unit. As such, it saves on power and other expenses like maintenance and repairs of the cooling / heating equipment.
- Some homeowners extend the “green building” as well to include solar panels to take care of the home's power needs. Rammed earth homes do not need so much energy like a conventional home so the solar panels can take care of the lighting and other needs. This type of home construction definitely saves energy bills.
- This type of home construction is extremely fire-resistant. There are no flammable components with rammed earth houses. The earth is packed as tight as possible that there is no way for combustion to take place.
- The walls are rodent-resistant. You need not worry about termites or other pests eating up the wall. There are no food sources offered by the walls.
A completed rammed earth home is just the same as a conventional house. Power, wires, plumbing and other needs are installed in the usual manner. A lot of owners will not cover the walls and leave them as they are. Some make finishing touches by painting or placement of plasters.
