Imerys Celebrates 30 Years
of Sewpercoat in North America
Calcium aluminate has been used in sewer
environments since the 1940s. Initially, the
drivers were resistance to sulfates in soil,
rapid return to service and superior abrasion
resistance.
Over time, it became clear that Calcium
Aluminate Concrete showed improved corrosion
durability, even in the harshest sewer
environments. Studies were performed
to better understand the science behind
the improved performance and in the early
1990s SewperCoat, was developed specifically
to protect wastewater infrastructure
from biogenic corrosion.
The first installation of SewperCoat, in
Virginia in December 1991, was for a critical
connection chamber at a municipal wastewater
treatment plant. This connection
chamber was selected because of its extreme
corrosive environment. Since its rehabilitation
with SewperCoat, inspections have
been done every few years over the last 30
years, and the structure has exhibited virtually
no signs of corrosion or degradation.
This connection chamber is still in service
today, confirming that SewperCoat has offered
outstanding field performance against
biogenic
corrosion
for
three
decades.
Today, SewperCoat is the reference solution
installed daily throughout the North
American wastewater network and around
the world across five continents.
SewperCoat is a ready-to-use premix mortar
composed of 100-percent calcium aluminate
materials. It is specifically designed
for spray-applied installation methods to
provide a protective lining for structures
exposed to abrasion and biogenic corrosion
resulting from the hydrogen sulfide (H2S)
cycle that occurs in municipal wastewater
environments.
SewperCoat is part of the Imerys range of
solutions for the construction market. With
more than 100 years of expertise, Imerys offers
mineral-based solutions for the needs
of the construction industry. Its brands for
construction include SewperCoat, Fondag,
Ciment Fondu and Ibeco. *
