Savcor Products Australia launch new compact and innovative galvanic anodes for concrete structures
Concrete repair in chloride contaminated structures causes incipient anode formation and results in reinforcement corrosion and concrete spalling at the border of repair areas. Performing the repair work using high resistivity concrete and installing galvanic anodes in the parent concrete at the edge of the repair patch can ensure targeted current delivery to the high-risk corrosion area in the concrete around the repaired locations.
Savcor Products Australia is launching the new anodes on to the Australian market. The compact, alkali-activated zinc anode is simple to install, is suitable for embedment within the concrete cover, and has 130 grams of zinc which provides long-term protection and excellent current distribution along the edge of the repair area.

New patented innovation: SPA discrete anode
Discrete anodes in concrete have been used extensively in reinforced concrete structures especially for concrete elements located in tidal and splash zones.
Due to their encapsulation within the concrete, discrete anodes eliminate the risk of grout acidification resultant from sea water in splash zones. These anodes are proven to be sound and highly effective for the corrosion prevention of reinforced concrete piles, beams and headstocks.
A new state-of-the-art development from Savcor Products Australia improves and economises the installation process for discrete anodes in concrete. The new patented SPA 18 plus and SPA 26 plus anodes incorporate centralised spacers which centre the anode within the designated hole eliminating potential short circuits between the anode and re-bar by providing sufficient grout cover to encapsulate the ribbon mesh. This further eliminates the need for any down-the-hole covermeter testing and multiple drilling into the concrete to find the appropriate locations for installation.
All new SPA 18 plus and SPA 26 plus anodes will be supplied by Savcor Products Australia with the new spacers included at no additional cost. This patented invention will guarantee major reductions in the cost of corrosion prevention by eliminating multiple holes and unnecessary drilling into existing concrete and significantly reducing engineering time during site testing.
- Major reduction in cost for anode installation.
- Eliminates weakening of the structure from excessive drilling.
- Very fast installation.
- Elimination of short circuits between anode and rebar.
- Major reduction in engineering time during site testing.

Vapour Phase Corrosion Emitters Explained
Vapour phase corrosion emitters are small, specialised devices designed to provide corrosion protection for metal components and parts which are enclosed in non-ventilated control boxes. The Vapour phase Corrosion Inhibitor (VpCI) emits vapours that form a monomolecular protective coating on internal metal surfaces. This coating protects critical, complex and expensive electronic equipment from corrosion initiation during operation, shipping or storage.
Three products from Cortec provide long term protection against corrosion in the presence of adverse conditions including salt, moisture, airborne contaminants, H2S, SO2, NH3, and others. These products all provide a similar level of protection.
VpCI-101 is a small patented device from which Vapour phase Corrosion Inhibitors are slowly released.
VpCI-105 & VpCI-111 are small patented plastic emitters with a breathable Tyvek® membrane through which corrosion inhibitors are slowly released.
- VpCI-101 will protect cabinets or tool boxes of up to 1 cubic foot (28 litres).
- VpCI-105 will protect cabinets or tool boxes of up to 5 cubic feet (142 litres).
- VpCI-111 will protect cabinets or tool boxes up to 11 cubic feet (312 litres).
Vapour Phase Corrosion Emitters - Easy To Install
VpCI emitters are simple and convenient to install. The devices should be installed at the earliest possible time, preferably during manufacturing or assembly.
To install, simply select a space within an enclosure where corrosion protection would be useful. Ensure that the surface to which the device will be affixed is clean and free of debris. Using the adhesive tape at the bottom of the device, affix the device to the clean surface.
For volumes greater than the emitter size, multiple devices may be used. If the enclosure is not totally airtight or if the access doors are opened frequently, replace the emitters more often than every 2 years. After periods of heavy maintenance replace the device.

SPA’s system uses Agilent Data logging equipment which provides the latest and most reliable technology in data logging equipment.
Remote Monitoring Equipment
One of the most important requirements of a CP system is the continuous delivery of CP current to the structure. While it is required to undertake system testing and adjustment once every year in conjunction with the inspection of the structure, it is essential to ensure that current is being delivered at all times. SPA uses Agent G2 technology for the online monitoring of CP systems. The Agent G2 unit is heavy duty and reliable communication equipment which offers 24/7 access to the operating data of the system and includes an alarm function via email or SMS messaging.

State of the art technology for long term durability and performance excellence
The original concept for the discrete anode was developed some 20 years ago. Since then many types of discrete anodes have been installed in a large number of concrete structures around the world. Some of the issues with the earlier types of discrete anodes were related to the durability of the anode wire and the long term performance of the electrolyte surrounding the anode.
Discrete anodes are not suitable for all applications, especially for thin con- crete elements or where the reinforcement is randomly spaced within a structure. The main area of application of discrete anodes would be thick reinforced concrete elements such as beams, headstocks or piles in tidal/ splash zones where the application of ribbon anodes leads to grout acidification in most cases.
Having in mind the long term durability of the cathodic protection compo- nents installed permanently in concrete and the importance of delivering a CP system with low maintenance costs, SPA has developed a state of the art discrete anode which can be supplied at different lengths (from 100mm to 800mm) and provides excellent current distribution and allows for full encapsulation of the anode mesh by the grout material. SPA’s anode, if installed in a suitably size hole in the concrete and in conjunction with suitable cathodic protection grout, will provide the optimum solution for cathodic protection installations.
SPA’s anode is constructed using grade 1 Titanium conductor rods and conductor bars, Elgard/De Nora Titanium MMO ribbon mesh and is manufactured under strict quality assurance procedures. Each discrete anode has a
unique identification number and is tested individually to ensure full compliance to the specification.
Type 1 : SPA 26
Type 2 : SPA 18
Titanium conductor bar tail / rod grade 1 Titanium in accordance to ASTM B265.
Type 1 (4 ribs/3 ribs) 2.1mA / 1.575 mA per 100mm active length.
Type 2 (4 ribs/3 ribs) 1.4mA / 1.05 mA per 100mm active length.

Stainless steel, carbon steel and polyethylene casing spacers from Advance Products and Systems are the first choice in ensuring the integrity of a carrier pipe when installed in casing.
Mechanically speaking... casing spacers do the job they’re supposed to do.
Problems using wooden skids:
- No long term integrity
- Wood rots and pipe will settle
- Easily dislodged
- Contributes to point loading of carrier pipe
- Allows bacterial corrosion
Advantages of Casing Spacers:
- Securely and uniformly supports the casing pipe
- Electrically insulates
- No casing filler needed
When comparing wood skids to casing spacers, we consider the potential liability arising from wood skids to be much higher.
Wood skids are:
- Are difficult to install
Require several workers to attach
Are resistant to sliding, making pushing of the pipe more difficult
Require annulus space filler
Have a high failure rate
Whereas casing spacers:
- Install easily and quickly
Are installed by one person
Slide easily - low coefficient of friction
Require no backfill
Have a proven reliability
Provide long term corrosion protection
Environmentally, it makes more sense to use manufactured spacers, removing the need for wood. In some areas where special hard woods are specified, the growth of hardwood trees has rapidly diminished.
APS’s spacers are made of recycled metal, plastic and polyethylene, use no wood and therefore eliminate the need for the cutting down trees thus helping to preserve our environment.
APS’s casing spacers are made from recycled metal, plastics and polyethylene. We don’t have to build them that way but we feel that it’s important.
