CeramycGuard™ on Trial with United Utilities

 

CeramycGuard™, 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 10m² 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™ 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™ 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™ was applied over the CeramycGuard™ 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™ 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.
