Service Penetration Termite Protection
Penetration protection as per AS 3660.1
Penetrations Are Critical Entry Points
Service penetrations are among the most common concealed termite entry points in modern construction. Plumbing pipes, electrical conduits, hydraulic services, communication cabling and mechanical services passing through concrete slabs create interfaces that require termite management measures to assist in preventing concealed termite entry into buildings.
As concrete naturally shrinks during curing, small gaps can develop around pipes and conduits. These gaps may provide termites with concealed access pathways into the structure if appropriate termite management systems are not incorporated during construction.
Vale Pest Group provides service penetration protection solutions for commercial construction projects, and residential projects through the builder. Our team works closely with builders, developers and project managers to install compliant termite management systems that integrate seamlessly into the construction process.
What Are Service Penetrations?
A service penetration is any pipe, conduit, cable or service that passes from the earth and through a concrete slab, footing or other structural element.
These penetrations are necessary for the operation of modern buildings, however they also create termite entry points in the concrete slab that require protection.
Service penetration protection involves installing approved termite management systems around the penetrations to assist in preventing concealed termite entry while maintaining compliance with project requirements and applicable Australian Standards.
Why Service Penetrations Require Protection
Concrete Shrinkage Creates Gaps
Concrete naturally shrinks as it cures. As this process occurs, small gaps can develop around service penetrations where pipes and conduits pass through the slab.
Without appropriate termite management measures, these gaps may create concealed termite entry pathways into the building.
Multiple Services Increase Risk
Modern buildings often contain numerous penetrations for plumbing, hydraulic, electrical, communications and mechanical services.
Each penetration creates a potential termite entry point that should be incorporated into the overall termite management system.
Concealed Entry Points
One of the greatest risks associated with service penetrations is that termite activity can occur without visible signs of infestation.
Termites may gain access to structural timbers and other susceptible materials through concealed pathways around penetrations, making early detection difficult.
How Service Penetration Protection Works
Service penetrations passing through concrete slabs represent one of the most common locations for concrete shrinkage to create termite entry pathways.
Prior to concrete placement, a flexible termite collar is installed over the service penetration and secured to the pipe using a cable tie.
Once concrete is poured, the collar becomes compressed between the slab and the pipe. The flexible material folds tightly against both surfaces and remains embedded within the concrete.
As the concrete cures and naturally shrinks away from the penetration, the flexible collar is released and expands into the newly created gap.
This allows the termite barrier to maintain protection continuity around the service penetration while accommodating normal concrete shrinkage.
Our Service Penetration Protection Applications
Pre-Slab Service Penetrations
Termite collars are fitted around plumbing pipes, conduits and other services prior to pouring the slab. As concrete naturally shrinks during curing, gaps can develop around service penetrations. AS 3660.1 requires termite collars to accommodate up to 15 mm of concrete shrinkage, helping maintain protection around the penetration and reducing the risk of concealed termite entry into the building.
Multiple Pipe Clusters
Commercial and multi-residential projects often contain grouped service penetrations where multiple pipes pass through the slab in close proximity.
These areas require careful installation to maintain continuity of termite protection around all services
Commercial Construction Projects
Large commercial projects frequently contain complex service layouts involving hydraulic services, electrical systems, communications infrastructure and mechanical plant installations.
Vale Pest Group works closely with project teams to ensure service penetrations are protected while maintaining construction schedules and compliance requirements.
Cut Outs & Infill Slab Works
When existing slabs are cut to accommodate new services, additional penetrations and construction joints are created.
These modifications can introduce new termite risk areas if termite management measures are not reinstated before the slab is repaired.
Our team installs termite management systems to cut-out and infill slab applications to help maintain continuity of termite protection following building modifications and upgrades.

Why are service penetrations protected?
Service penetrations are protected because concrete naturally shrinks as it cures. As the concrete shrinks, gaps can develop around pipes, conduits and other services passing through the slab. These gaps can provide concealed termite entry pathways into the building if appropriate termite management measures are not installed.
Why do gaps form around service penetrations?
Concrete and service pipes behave differently during the curing process. While concrete naturally shrinks, pipes and conduits do not. This can create small gaps around penetrations that may allow termites to gain concealed access into the structure.
Can termites enter through concrete slabs?
Termites cannot damage or consume concrete, however they can exploit gaps, cracks and concealed pathways within and around slab systems. Service penetrations, construction joints and slab cracks can all provide potential termite entry pathways if they are not appropriately protected.
What types of services require protection?
Termite management systems are commonly installed around plumbing pipes, hydraulic services, electrical conduits, communication services, gas services and mechanical services passing through concrete slabs.
Are service penetrations a common termite entry point?
Yes. Service penetrations are recognised as one of the most common concealed termite entry points in modern construction because concrete shrinkage can create gaps around pipes and conduits. Protecting these interfaces forms an important part of an overall termite management strategy.
What happens when new pipes are added after construction?
When an existing slab is cut to install new services, additional service penetrations and construction joints are created. These newly formed interfaces require termite management measures before the slab is reinstated to help maintain continuity of termite protection.
Why are termite collars installed around service penetrations?
Concrete naturally shrinks as it cures. As the slab shrinks away from the pipe or conduit, a gap can develop around the service penetration. This gap can provide a concealed termite entry pathway into the building.
AS 3660.1 recognises that concrete shrinkage occurs and requires termite collars to accommodate up to 15 mm of shrinkage around service penetrations. Termite collars are designed to maintain protection around the penetration as the concrete cures and moves, helping to seal the gap that may otherwise develop between the slab and the service.
This is why service penetration protection is a critical component of termite management systems in modern construction.
Do service penetration collars need to be inspected before the slab is poured?
Collars are installed and checked prior to concrete placement to confirm correct fitting and positioning around each penetration, since this is the only point at which the installation can be visually verified before it’s compressed and embedded within the slab.
Do you provide compliance documentation?
Yes. Vale Pest Group can provide Certificates of Compliance, warranty information and marked installation plans identifying the locations of termite management measures installed throughout the project. For Queensland projects, Form 12 and Form 43 documentation can also be provided where required.
