Structural Concrete Repair Mortar
ARDEX BR 345 is designed for the structural patching and reinstatement of damaged concrete.
Concrete structures can deteriorate due to a range of chemical and mechanical causes, including concrete spalling. ARDEX BR 345 provides a high-build repair mortar for reinstating suitable damaged areas.
Its combination of MICROTEC® fibre reinforcement, polymer modification, shrinkage compensation and high electrical resistivity makes it suited to professional structural concrete repair applications.
High-Build Concrete Repair Up to 80 mm
ARDEX BR 345 can be applied at thicknesses of up to:
80 mm
This high-build capability makes ARDEX BR 345 suitable for substantial concrete reinstatement and patching applications.
The mortar can be applied to:
Vertical surfaces
Horizontal surfaces
Overhead surfaces
Always follow the manufacturer's current technical documentation for substrate preparation, mixing, application thickness, curing and finishing requirements.
Concrete Spalling Repair
ARDEX BR 345 is designed for reinstating concrete structures affected by concrete spalling and other chemical or mechanical causes of deterioration.
It can be used where damaged or deteriorated concrete has been removed and the remaining structure requires reinstatement with a suitable structural repair mortar.
The overall repair system should be designed and installed in accordance with the project specifications and manufacturer's recommendations.
High Electrical Resistivity
One of the key characteristics of ARDEX BR 345 is its high electrical resistivity.
The product has an electrical resistivity of:
> 15,000 Ω·cm
High-resistivity repair materials can be an important consideration in concrete repair projects where electrical properties and reinforcement corrosion management form part of the repair strategy.
Active Corrosion Inhibitor
ARDEX BR 345 contains an active corrosion inhibitor, providing an additional feature for concrete repair applications where reinforcement corrosion is a consideration.
Combined with appropriate substrate preparation, reinforcement treatment and concrete repair procedures, ARDEX BR 345 can form part of a comprehensive concrete durability and corrosion-management strategy.
Polymer-Modified Repair Mortar
ARDEX BR 345 is polymer modified, providing a high-performance material for structural concrete patching and reinstatement.
The polymer-modified formulation works together with the MICROTEC® fibre reinforcement and shrinkage-compensated properties to provide a repair mortar designed for demanding applications.
Shrinkage-Compensated Concrete Repair
ARDEX BR 345 is formulated as a shrinkage-compensated structural repair mortar.
Controlling shrinkage is an important consideration when reinstating damaged concrete, particularly where the repair must maintain integrity and durable contact with the existing concrete substrate.
Always follow the manufacturer's current installation and curing requirements.
MICROTEC® Fibre-Reinforced Technology
ARDEX BR 345 incorporates MICROTEC® fibre-reinforced technology.
The fibre-reinforced formulation is designed for structural concrete patching and repair applications, providing reinforcement within the repair mortar matrix.
Potable Drinking Water Applications
ARDEX BR 345 is compliant with AS/NZS 4020 – Potable Drinking Water.
This makes the product suitable for appropriate concrete repair applications associated with potable drinking water infrastructure, subject to the specific project requirements and conditions of use.
Potential applications may include suitable repair work associated with:
Potable water infrastructure
Water treatment facilities
Water storage structures
Concrete water infrastructure
Drinking water-related concrete repairs
Always confirm suitability for the specific application and follow the manufacturer's current technical documentation.
Structural Concrete Repair Applications
ARDEX BR 345 is suitable for a range of professional concrete repair applications, including:
Concrete spalling repair
Structural concrete reinstatement
Concrete patching
Repair of mechanically damaged concrete
Repair of chemically damaged concrete
Vertical concrete repairs
Horizontal concrete repairs
Overhead concrete repairs
High-build concrete repair
Concrete repair where high electrical resistivity is required
Concrete repair associated with corrosion management
Appropriate potable-water infrastructure repairs
