Perimeter Wall Construction

Wall Section with OpeningsThis shows a section of the perimeter wall, with column openings each 2.5 m. Notice that the columns are always poured after the blocks are laid for better adhesion. dozer

|
Pouring a ColumnThe columns are poured after the blocks are laid in place. Here a piece of metal is being used to vibrate the concrete into place within the formwork.dozer

|
Rebar Framework for Top BeamThe rebar used in the top beam is 2 strands of 9mm rebar with 'chain' sections to keep the bars equidistant.dozer

|
Form Work for Top BeamThe form work is in place to pour the top horizontal beam.dozer

Wetting Down the WallIt is essential to wet the wall down prior to application of the render coat.dozer

Colored Render Coat being AppliedHere is the render coat being applied. This takes some trial and error to get correct with color render.dozer

Red Perimeter Wall SectionAesthetically, the wall finish looks nicer without the underlying blocks showing through. Although the pattern seems to diminish with time (due to the blocks drying out), we now have figured out how to get no show through at all. dozer

Rough Coat RenderThis shows a color coat of render being applied over a dried rough coat render. There is a certain technique which we employed after some initial missteps to get the block outline not to show through to the color coat.dozer
