An overview highlighting SRCP’s range of Sacrificial & Impressed Current Anodes, Monitoring equipment and Zinc Tape.
SpecialistRepair & ConstructionProducts:
The simplest CP system ever.Galvanic anode systems are much
simpler than impressed current
systems and the ZLA system is
particularly simple. In the best case
scenario simply clean the surface,
pull of the ZLA backing tape,
press the anode to the concrete
surface and connect the ZLA to the
reinforcement.

Zinc Layer Anode is zinc sheet
backed with activator paste,
adhesive and a backing sheet.
Applied to a concrete surface it
provides sacrificial galvanic cathodic
protection to actively corroding
reinforcement. Manufactured by
corrPre Engineering in Italy.

The Roll Anodes enable the precise
location of anodes for a particularly
simple internal anode system. In the best-
case scenario simply drill holes, insert the
Roll Anode, fill with activator paste and
connect to the reinforcement.
A simply applied internal anode system.
Rolled zinc sheet for insertion into
drilled holes, which are then filled
with Zinc Activator Paste (ZAP) to
give a precise and easy location of
anodes within sound concrete where
reinforcement is corroding. With a
connection to the reinforcement
provides galvanic cathodic
protection to reinforcement.

No more hard breakout.Professional long lasting repairs at
a fraction of the cost. Providing full
cathodic protection using GSC Super
Anodes eliminates the need for expensive
breakout of hard, sound but contaminated
concrete.
GSC Super Anodes are specifically
designed to cathodically protect
reinforcement in concrete. The
anodes are embedded within the
repair concrete or mortar and
are electrically connected to the
reinforcement. They are perfect for
the localised patching of corrosion
induced damage.

Limited access or wet conditions?All components of the system are resistant
to corrosion and hence the system can be
used in corrosive environements such as
the underside of wharf decks. The system
is easy to use in restricted or confined
spaces as it is located on the surface of
the concrete.
Cassette is a ribbon anode
impressed current cathodic
protection (ICCP) system. Instead
of burying the ribbon anode in the
concrete it is mounted in an inert
panel with a felt pad to spread
the current from the ribbon to the
concrete surface.

Now it is simple to design and install a
web based monitoring & control system
so there is no need to go to site for testing.
A new generation of water based conductive paint anodes is now available.
Zebra is a conductive paint
impressed current cathodic
protection (ICCP) system for the
repair of concrete structures.
Employing conductive ZEBRA
paint and connecting the steel
reinforcement to the protective
circuit puts a stop to concrete
corrosion.
Advantages• Restoration work completed 30 - 40% faster• Repairs are significantly cheaper• Shorter closures of structures• No need for high-pressure water jetting• No need to remove large amounts of concrete• Web based monitoring• Proven technology

Advantages• Easy economic installation with grinding,
drilling or embedding• Natural gas venting - The microcrystalline
structure of silicates has a pore size that allows the free passage of water vapour and oxygen
• Longevity - The insoluble silicates formed in the chemical reaction are resistant to strong acid attack
• Ample protection - Satisfies the 100mV criteria for e� ective cathodic protection according the international standard ISO12696
• Convenient pilot testing - easily apply and displace each individual Corrodisc anode to analyse the e� ects of steel polarisation
