SIKA FERROGARD 510 PATCH

Sika® FerroGard®-510 Patch is a zinc-based discrete
sacrificial anode placed inside a repaired area in a reinforced concrete structure which is corroding as a
result of chloride ingress and/or carbonation.
Sika® FerroGard®-510 Patch anodes are placed along
the perimeter of the repair area and fixed to the reinforcement prior to the application of a concrete repair
system. The reinforcement outside the repaired area
is at greatest corrosion risk owing to the passive condition of the reinforcement within the repaired area.
Sika® FerroGard®-510 Patch anodes corrode preferentially to the surrounding reinforcement, offering protection against incipient corrosion damage.
Standard repair mortars, bonding primers and reinforcement corrosion protection coatings can be used
as Sika® FerroGard®-510 Patch is placed in the parent
concrete and not within the repair mortar.
