Terralite
™ (page 3)
Easy to install Terralite™ retaining
wall
Step 1.
Prepare a level base
dig a trench 6" (15 cm) deep and 15" (38 cm) wide.
Throughly compact the base, and partially fill with granular
draining material ( e.g. coarse sand). Compact and finish
to a level base ± 3" (7½ cm) below grade.
Step 2.
Install the first course
Place the first row of TERRALITE™ against a stretched
levelling line from one end of the wall to the other. Level
each block from front to back and then place lightly compacted
drainage layer behind the blocks. Half inch crushed rock should
be used for filling the blocks ( or fertile soil when plantability
is a consideration). Install a drainage pipe behind the blocks
where a waterlogged condition occurs.
Step 3.
Install successive courses
Complete the wall row by row, either using stack or half lap
bond. Use granular fill to maintain alignment and uniform
setback & backfill behind the wall.
Step 4.
Finishing your wall
The top course may be filled with good soil for planting,
or with maintenance free crushed rock. Alternatively TERRACAP™
MATCHING WALL CAPS may be used.
Walls over 3 feet (1m) high may require terracing advice from
a professional landscaper or from your municipal inspector.
