DOUBLE-SIDED WALL: 90° CORNERS
Building a 90º corner on a Lafitt and Melville Tandem wall
requires installing a wall end (described earlier), then juxtaposing
a second wall perpendicular to it .
Glue every course in the wall corner using Permapro adhesive .
Once again, for a natural look, avoid aligning vertical joints from
one row to the next on all visible surfaces .
90º CORNER IN A DOUBLE-SIDED 90
AND 180 WALL
Building a 90º corner on a wall requires installing a wall end
(described earlier), then juxtaposing a second wall perpendicular
to it . The second wall can be built starting with double-sided
Tandem 90 or 180 units . Adhere every course in the wall corner
using Permapro adhesive .
Corners are built using the options available for that height (90
or 180) . These options were illustrated and explained earlier in
this document . The selection of corner module heights and their
positioning in the wall is a matter of aesthetics . The 90 and
180 units must be inserted in a similar proportion to the remainder
of the wall so that they harmonize .

Building a 90º corner on a wall requires the assembly
described below .
Some components may have to be cut to adapt to the final anchor .

CAPPING A DOUBLE-SIDED WALL
Double-sided Tandem walls are completed using
Esplanade chiseled
capping units (60 × 381 × 1067 mm), laid side by side . Each unit
is textured on both sides (front and back), and one of two modules is
textured on one end . Modules can be rotated 180º for more flexibility .
To cap a 90° corner, simply install two capping units at a 90° angle .
For curved walls, capping units must be bevelled on site to match
the final shape of the wall .
Options: Straight and bevelled Celtik wall system capping units .
Note that all capping units must be attached to the last row
of
Tandem units using Permapro concrete adhesive .
