BOSTON, MASSACHUSETTS

Project History
The Harbor Towers were designed by architect I.M. Pei and
constructed in the 1970s. In the mid 1990s the buildings
had shown effects of their location in Boston Harbor.
Over a three-year period restorations and waterproofing
to the building were made using Conpro Lastic. In 2008 the
Towers were in need of a touch up, the appearance of the
buildings was mottled and extremely dirty. These effects
were again due to the constant ocean spray from the harbor
coupled with the airborne particulate from the ten-year long
“Big Dig”. Working with WJE, contractor NER Construction
Management, Inc. found that the best solution was to prime
the existing surface using Conproco Point 5 acrylic primer
and recoat with Conpro Lastic elastomeric coating.
The building was power washed, primer was applied,
followed by two 15-mil coats of Conpro Lastic. Conpro Lastic
is a waterproof membrane, ideal for these high-rise buildings
as it bridges minor cracking and performs well with the harsh
conditions of the city and the driving rains of the North Atlantic.
