Construction
Chevloc walls are normally built on a simple horizontal
foundation, which should be constructed at a frost-free depth
sufficiently deep to cover the Chevloc base block units.
It
is essential before commencement of building that the base
course of blocks is checked for orientation and line and level.
During construction it is recommended that a batter board
be used to check that the correct batter is being achieved.
In a battered wall (6:1) the blocks are placed so that the
thinner segments are all outward facing. As building progresses
these interlock to form a wall with each course giving a rise
in level of 150mm while stepping back by 25mm.
A vertical wall is achieved by laying alternating courses
of units with thinner and thicker segments outward facing,
again giving a rise in level of 150mm.
If either a battered wall or a vertical wall is required
to be more than one unit thick structural integrity is maintained
by sandwiching a layer of polymer grid between every third
and fourth course. |
