Step 1: Site Preparation
The job site
is excavated for a minimum of work clearance; an aggregate bed is prepared
for subfooting and frost-free foundation
Step 2: Subfooting
A smooth concrete setting
slab is applied. Smaller units can be placed in wet concrete as well.
Step 3: Installation
CreCast wall units are
lowered into position on shims for perfect alignment and grouting purposes.
Step 4: Grouting
Wall sections are grouted
in place, achieving a solid connection with subfooting.
Step 5: Backfill / Drainage
CRECAST walls are provided
with drainage and backfill (where applicable) to final grade.
