If you’re building a new home, office or commercial facility, termite management should be considered before the concrete slab is poured. One available method is a pre-construction horizontal soil treatment, commonly called a slab spray. This treatment applies a registered termiticide to prepared soil beneath specified parts of the building. Newcastle Pest Exterminators offers slab spray treatments for residential and commercial construction projects. We coordinate with builders and apply registered termiticides according to the approved product label, construction plans and specified application rates.
Many property owners underestimate the cost and damage that termites can cause. A concrete slab alone does not remove the risk of termite entry. Subterranean termites travel through soil and may gain concealed access through construction joints, gaps around service penetrations, cracks, slab edges and areas where later work has disturbed the termite management system.
Termites do not usually eat or damage sound concrete. Instead, they use openings in or around the slab to reach timber and other cellulose-based building materials. Once inside, they can damage frames, flooring, skirting boards, cabinetry and other timber components. These pests can move in before you even finish construction. Our professional slab spray services offer peace of mind and security.
Newcastle Pest Exterminators provides pre-construction termite management for suitable residential and commercial projects. Depending on the approved design, this may include a horizontal soil treatment beneath the slab, treatments around service penetrations, external perimeter measures or integration with physical termite barriers.
The selected system must suit the construction details and be applied according to the registered product label. After installation, the property will still require accessible inspection zones and regular professional termite inspections.
What is a Slab Spray?
A slab spray is the common name for a pre-construction horizontal soil treatment. Before the concrete slab is poured, a licensed technician applies a diluted, APVMA-registered termiticide to designated soil or compacted fill beneath the building.
The objective is to create a continuous treated zone between subterranean termites in the soil and the structure above. Depending on the building design, additional treatment may be required around pipe penetrations, joints, slab edges and the external perimeter.
The product, dilution rate and application volume must follow the approved label. For example, registered termiticide labels specify minimum application rates for horizontal treated zones beneath slabs. If construction work, excavation or soil movement disturbs the treated zone, the affected area may require reapplication. elabels.apvma.gov.au
A slab spray manages the risk of subterranean termite entry. It does not make the building termite-proof, and it does not replace regular inspections or other termite-management components specified for the project.
How are Slab Sprays Applied?
Slab-spray work must be coordinated with the builder because the treatment occurs at a specific stage of construction. The soil or compacted fill must be prepared and accessible before the slab is poured. Application timing and site preparation will depend on the construction sequence, system design and product label.
Before treatment, the technician confirms:
- The approved building plan and area requiring treatment
- The location of slab edges, joints and service penetrations
- The soil or compacted-fill condition
- The termiticide, dilution rate and required application volume
- Areas that need separate or complementary barrier components
The technician then applies the termiticide evenly across the specified area at the registered rate. Additional applications may be required around pipes, penetrations and other potential entry points. The treated area must be protected from excavation, soil movement, excessive water and other disturbance before the slab is poured.
If another trade disturbs or removes treated soil, the builder should contact the termite-management installer before covering the area. The affected section may need to be treated again to restore continuity.
Documentation After Treatment
After completing the treatment, the installer should provide documentation identifying:
- The product and active ingredient used
- The areas treated
- The application date
- The dilution and application rates
- Any complementary barrier components
- Areas that could not be treated
- Inspection, maintenance and retreatment requirements
- Any warranty conditions that apply
Keep these records with the building documents. Future owners, builders and pest management technicians may need them when inspecting, renovating or extending the property.
Why Choose a Slab Spray?
A pre-construction soil treatment may suit projects where the approved termite-management design requires a horizontal treated zone beneath the slab. It can also work alongside physical barriers at penetrations, joints and perimeter details.
Before selecting a system, consider:
- The slab and footing design
- Soil type and drainage
- Service penetrations and construction joints
- Whether later landscaping or paving could disturb the treated zone
- Product longevity and retreatment requirements
- Future access for inspection
- Other physical or chemical barrier components specified for the building
No single treatment suits every project. In some buildings, a combination of soil treatments and building-integrated physical barriers provides more complete coverage than relying on one measure alone.
Newcastle Pest Exterminators can review the project details, explain the available options and provide a quotation before the relevant construction stage begins.
