All buildings have joints that need some form of treatment.

Typical types of joints include:

• Construction Joints
• Expansion Joints
• Fire Rated Joints
• Seismic Joints
• Bridge / Road Joints

Polyseal’s experience with waterproofing techniques has led to an understanding of joints, their unique characteristics and the best way to treat them.

A well designed and installed jointing system, using materials such as Combiflex and Tricosal, will provide a waterproofing solution that will result in waterproof joints over the required design life.

Strict building regulations also call for Concrete slab and wall joints at vertical and horizontal surfaces to be fire rated and certified to minimise the risk of the spread of fire.

Road and bridge joints are designed for extremes in movement, environment and durability. Typically made of up a flexible joint with a steel plate cover for protection, it is important that the system is integrated into the structure to ensure a watertight system. Shopping Centre car parks and associated infrastructure are areas of typical application.



Polyseal specialises in the application of waterproof membranes and associated products on new and existing buildings.

Specific project requirements will determine membrane selection. Membrane types range from multi-layer bitumen torch on systems, to liquid systems applied with a roller or sprayed systems that can be touch dry in less than 30 seconds and can be applied at a daily productivity of up to 1000m2.

Correct selection of membrane will ensure a long lasting & durable product that will meet the client’s design requirements.

Areas of application include:

• Podium Decks
• Balconies
• Retaining walls / Basement Walls
• Internal Wet Areas
• Roof Decks
• Green Roofs
• Carparks
• Tunnels
• Tanks – Potable water, Sprinkler, Blackwater
• Bridge Decks
• Walkways

Protective Coatings

Protective Coatings

Appropriately chosen and well applied protective coatings assist greatly in maximising the service life and maintenance return period of infrastructure assets. Deterioration of concrete, steel and timber structures can lead to expensive repairs and downtime. Protective coatings provide an effective preventative maintenance measure that reduces costs in both respects.

Polyseal are familiar with a range of protective coatings designed to suit specific requirements. Working closely with our suppliers, Polyseal is able to offer the most appropriate solution for your project.

Protective coatings are typically applied to:

• Structural Steel
• External Concrete
• Steel or Concrete Piers
• Timber Structures
• Structures in a Marine Environment
• Miscellaneous Metalwork Items

As is the case with many occupied buildings, the renewal of coatings must be undertaken with minimal disruption to the customer’s everyday activities. Our experience and dedicated management team will ensure that any project carried out will be pre-planned to ensure minimal disruption.

Concrete Repair & Protection

Concrete Repair & Protection

Australia’s harsh natural and man-made environments provide mechanisms that attack concrete structures continually. From our residential buildings in coastal locations, to industrial and mining infrastructure in remote areas, Polyseal provide solutions and systems to assist asset owners to maintain and rehabilitate structures based on operational and budgetary requirements.

Services offered include:
• Patch repairs using proprietary repair systems
• ‘Micro-concrete’ or ’pea gravel’ concrete repairs to larger horizontal or vertical repair locations.
• Shotcrete repairs to large scale deteriorated areas.
• Removal and replacement of highly deteriorated structural elements.
• Hydro-demolition.
• Installation of sacrificial anode systems to ensure greater longevity of all of the above repair types.
• Installation of spray applied sacrificial anode coatings.
• Installation of zinc sheet anode systems.
• Design and installation of impressed current cathodic protection systems.
• Application of penetrating coatings such as silanes, siloxanes and migrating corrosion inhibitors.
• Crack injection systems for waterproofing and structural purposes including polyurethane and epoxy systems, rapid set  cementitious systems, crystalline waterproofing systems.
• Epoxy coatings and linings.
• Pile jackets and pile wrapping.
• Magnesite removal and repairs.

Structural Strengthening

Refurbishment and the change of use of structures and buildings, often introduces greater applied loads, or changes in the design load path. Structural strengthening is also often required as structures deteriorate over time due to corrosion of metallic, timber or concrete elements.

Modern strengthening methods use proven materials that offer less creep and elongation than steel and are less obtrusive, being thinner and lighter, yet offering up to ten times the tensile strength capacity of steel.

Strengthening methods include:
• Use of carbon fibre, aramid or glass fibre fabrics such as the MBrace System by BASF or the Carbodur range by Sika.
• Use of carbon fibre laminates.
• Increasing tensile strength characteristics on structures such as bridges, wharves, car park floor slabs, silos etc. using a combination of conventional and externally bonded fibre reinforcement systems.
• Reinforcement of areas where penetrations are to be made through existing floor slabs for example to install new stairs, escalators or the like
• Plate bonding systems whereby steel plates are bonded to existing structures using epoxy adhesives.

Building Repair & Refurbishment

Australia’s largely coastal building stock suffers deterioration due to the marine environment on a daily basis. Also Building practices of the distant and not so distant past have provided buildings with inherent defects and problems that require rectification. The need to upgrade or maintain the value of property investments also provides a driving force for the repair and refurbishment of buildings and infrastructure.

Polyseal offer a wide variety of services in this area and are able to handle the most complex of repair and refurbishment projects.

These services include:
• Major waterproofing rectifications of both internal and external wet areas.
• Replacement of windows and doors in timber, aluminium and steel.
• Design & construction of lightweight over cladding systems in Fibre-cement sheeting, pre-finished aluminium and other proprietary cladding systems.
• Cavity flashing and damp-proof course installation
• Balustrade removal and replacement to raised public spaces and balconies.
• Roofing and re-roofing in tiles, sheet metal and other proprietary systems.
• Internal refurbishment of hallways, foyers, stairwells and other common areas.
• Repair and refurbishment of swimming pools encompassing concrete repair to substructures, waterproofing and tiling.

Fire Safety Upgrades

The modern day requirements imposed by the Building Code of Australia in terms of fire safety, whilst stringent, are designed to safeguard the occupants of all buildings in the event of fire. These days any approval application for construction work is likely to be reviewed by the Local Authority for compliance with fire safety criteria.

Polyseal offer a wide ranging service to assist building owners with fire safety upgrades that includes:
• Fire separation works including fire rated walls and ceilings.
• Fire sealing using fire rated collars, pillows and sealants.
• Installation of fire rated doors and windows.
• Upgrades of fire hydraulic systems such as sprinklers, hydrants, fire hose reels and portable fire extinguishers.
• Installation of smoke and fire detection and alarm systems.
• Emergency lighting and signage.


When completing infrastructure projects in the face of demanding deadlines the grouting of machinery and rail mounting baseplates is often overlooked as being a critical factor in ensuring minimal maintenance in the future. Cracked or dislodged grout is often visible on facilities that have been in operation for periods of less than twelve months. The correct choice and detailing of grout in these areas is essential in order to avoid costly repairs and, worse still, the attendant down time of essential plant and equipment.

Polyseal offer expertise in the design and installation of grouted support systems using the latest in:
• Dry pack grouts.
• Hydraulic cement grouts
• Epoxy grouts
• Non shrink grouts
