CeramycGuard(TM) on Trial with United Utilities
CeramycGuard(TM), exclusively distributed by Haydale (AIM: HAYD)
in the UK is currently being trialled by United Utilities at their
wastewater treatment works in Oldham, UK. The unique low CO2
ceramic-polymer surface treatment has been applied to a 10m(2) area
of a newly commissioned final settlement tank. The trial will last
for a period of six months.
Previously, the internal face of the tanks on site have been
coated with a repair screed and topcoat, which have not achieved a
satisfactory service life because of the harsh, chemical
environment. The chemicals within the water create a chalky surface
with holes that reduce the reinforcement coverage. As a result,
repair work is having to be carried out at regular intervals,
requiring the tanks to be taken offline, which is both expensive
and time consuming.
CeramycGuard(TM) uses Haydale's proprietary silicon carbide
microfibres, along with nano-Alumina and Zirconia Silicates to
renew and preserve concrete surfaces by chemically bonding to the
concrete. The surface treatment fills the pores and microcracks to
create a new ceramic surface layer that is impermeable to corrosive
liquids such as acids and salts, and microbiologically active
solutions.
The CeramycGuard(TM) was applied by roller within 10 minutes.
The surface can be cured at five or 12 degrees, with the concrete
asset being back in service between 24 hours and seven days after
application, depending on the size of the area being treated. For
the trial, after seven days a topcoat of Haydale's QuartzSeal(TM)
was applied over the CeramycGuard(TM) to further inhibit the
ingress of water and chemical pollutants and to seal out dust and
dirt and protect against stains. This also makes the new surface
layer biologically impervious.
As a non-toxic water-based product that does not contain VOCs or
leachable organic constitutes, CeramycGuard's CO2 footprint is
significantly lower than epoxy systems by up to 50 times in an
equivalent application. Its unique properties can potentially
protect and extend the life of concrete assets such as final
settlement tanks by up to 30 years.
The application of the surface treatment is currently undergoing
a monitoring process, but as an asset preservation technology it is
anticipated to extend the service life of the final settlement
tank. At the end of the six-month trial, a thorough inspection of
the treated area will be carried out. The outcome of the current
trial could result in CeramycGuard(TM) being used to treat multiple
assets on the site to extend their service life. The benefits are
likely to be long-term cost savings by using a product that could
reduce the frequency of repairs with much lower CO2 emissions
compared to systems currently used to coat concrete.
