| PROBLEM: |
| Two, twenty-story apartment
buildings were experiencing serious leakage problems on
balconies due to cracked concrete. The artificial turf
on most of the balconies trapped moisture and contributed
to delamination of the sloped concrete topping. Not only
was water entering the suites, but further serious damage
due to the freeze-thaw cycle would inevitably require
major reconstruction work if the areas were not completely
waterproofed. |
| SOLUTION: |
| To determine the costs
and problems of this project, a test phase of 20 balconies
(between 200-550 sq.ft. ea.) was completed in year one.
All the glued-down carpet was removed and disposed of.
Many of the balconies had delaminated concrete which was
broken up with Kango guns and removed at a rate of 14
cu. yds. per day. Often working on a swing stage from
the outside building, new drain holes were drilled through
the concrete walls. The surface was trowelled with an
acrylic modified topping mix to provide a smooth finish
to accept the vinyl. After the Duradek was
glued down, the perimeters were secured with "L" trim,
used as a gum stop, and sealed with urethane. |
| Job Notes: |
| The successful completeion
of Phase I led to Phases II & III. A total of over
120,000 sq. ft. |
