What is soil poisoning in construction?

Soil poisoning in construction, also called termite soil treatment or anti-termite treatment, is the process of applying a chemical termiticide to the soil beneath and around a building's foundation to create a barrier that kills or repels subterranean termites. In South Africa, soil poisoning is a mandatory requirement for NHBRC-registered home builders and is required by many municipal councils before building plan approval. The treatment is most effective when applied pre-construction — before the concrete slab is poured — but can also be retrofitted to existing buildings using foundation drilling.

How much does soil poisoning cost in Pretoria?

Soil poisoning costs in Pretoria depend on the size of the building footprint, the construction stage, and whether pre-construction or post-construction treatment is required. Post-construction foundation drilling treatment is generally more labour-intensive than pre-construction treatment and may cost more depending on access. Pest Invasion Control Pretoria provides free, no-obligation quotes for all soil poisoning projects — call 012 460 6284 for a price specific to your site. We serve residential homes, commercial buildings, housing developments, and all building types across Pretoria and Centurion.

Is a soil poisoning certificate required for NHBRC registration?

Yes. The NHBRC (National Home Builders Registration Council) requires a soil poisoning compliance certificate as part of the new home enrolment process in South Africa. The certificate confirms that soil treatment was performed by a registered professional using an approved termiticide at the correct application rate. Pest Invasion Control Pretoria issues compliance certificates on completion of every soil poisoning treatment. Our certificates are accepted by the NHBRC and by Tshwane municipality and other local councils for building plan approval.

What is the difference between pre-construction and post-construction soil poisoning?

Pre-construction soil poisoning is applied directly to the excavated soil, trenches, and compacted surface beds before the concrete slab is poured. The treated areas are then covered with plastic sheeting and the concrete is poured over them, sealing the chemical barrier permanently into the foundation. This is the most effective and cost-efficient method. Post-construction soil poisoning is used on existing buildings where pre-construction treatment was not performed. Access holes are drilled around the foundation perimeter and termiticide is injected under pressure to create a barrier beneath the existing slab. Both methods come with a 5-year guarantee from Pest Invasion Control Pretoria.

How long does soil poisoning last?

Pest Invasion Control Pretoria's soil poisoning treatments come with a 5-year guarantee. The SABS-approved termiticides we use are specifically formulated for long-lasting residual protection in South African soil conditions. The 5-year period covers the most critical construction and early occupation phase during which termite pressure is highest. After 5 years a re-treatment or inspection is recommended depending on local termite activity and soil conditions.

When should soil poisoning be done during construction?

Soil poisoning should be done after all trenches and foundations have been excavated and compacted, but before the concrete slab is poured. This is the ideal window as the soil is fully exposed and the termiticide can be applied at maximum coverage and depth. Applying the treatment too early — before compaction — or too late — after the slab is already poured — reduces effectiveness and may not satisfy NHBRC requirements. Call Pest Invasion Control Pretoria as soon as your foundation excavation is complete and we will schedule treatment around your concrete pour date.

Can soil poisoning be done on an existing house?

Yes. Post-construction soil poisoning can be applied to any existing home or building where pre-construction treatment was not performed or has expired. Our technicians drill access holes around the foundation perimeter at regular intervals and inject termiticide under pressure into the soil beneath the slab. This retrofits a chemical termite barrier into an established building. The treatment is also recommended when extending or adding onto an existing structure to ensure the new addition is protected to the same standard as the original building.

Is soil poisoning safe for people, pets, and gardens?

Yes. The SABS-approved termiticides we use are specifically formulated and tested for safe use in residential and commercial construction environments. Once applied and covered or cured, the chemical barrier poses no risk to occupants, pets, or surrounding garden areas. The treatment is contained within the soil beneath the foundation and does not leach into surface garden beds or water sources when applied correctly. Our certified technicians follow all safety protocols and application guidelines during every treatment.

What type of termites does soil poisoning protect against?

Soil poisoning is specifically designed to protect against subterranean termites — the species responsible for the vast majority of structural termite damage in Pretoria and Gauteng. Subterranean termites live in underground colonies and build mud tubes through soil and along foundations to access the timber in buildings. The chemical soil barrier intercepts these tunnels and eliminates any colony attempting to breach the foundation. Without a soil barrier, subterranean termites can completely destroy the timber structure of a home within 3 to 5 years without any visible signs until severe damage has already occurred.

Do you provide soil poisoning for housing developments and estates?

Yes. We provide bulk soil poisoning treatment for housing developments, residential estates, commercial parks, warehouses, schools, retail outlets, and large industrial builds across Pretoria, Centurion, and Gauteng. We work directly with contractors, project managers, and developers to schedule treatment around construction timelines and issue individual compliance certificates for each unit or structure treated.

Call 012 460 6284 to arrange your free on-site assessment.

Why is soil poisoning necessary in Pretoria?

Pretoria and Gauteng are in a high termite-risk zone due to the region's warm climate, sandy soil composition, and widespread subterranean termite populations. Termites can target any building regardless of construction type — they detect wood through the smallest cracks in foundations and can devastate a structure silently over years. Soil poisoning is the most cost-effective form of termite prevention available and is far less expensive than repairing termite damage after the fact. In Pretoria it is both a regulatory requirement for new builds and best practice for any property owner wanting to protect their investment.

Soil Poisoning Pretoria

Soil Poisoning Pretoria is the most effective way to protect your home or business from termites. This treatment creates a barrier in the soil that stops termites before they can damage your property. At Pest Invasion Control, we use certified methods and offer a 5-year guarantee for every soil treatment. Our team works across Pretoria to provide safe, reliable, and affordable protection for new and existing buildings

Our Treatment Process

At Pest Invasion Control, our Soil Poisoning Pretoria services are strongly recommended before any structure is built to prevent termite infestations. We begin by using a high-pressure pump to spray all trenches, compacted soil, and surface beds where termites are likely to move. This step protects the foundation of the building before the concrete slab is poured.

Once treated, the areas are covered with plastic sheets to prevent rain or sunlight from breaking down the chemicals. After this step, the concrete slab is poured, and the treatment binds with the soil. This creates a strong barrier that exterminates active colonies and stops termites from accessing your home or building.

Termites can target any property, regardless of its construction type. Once they detect wood, they alert the colony, starting a feeding frenzy. That’s why soil poisoning is one of the most effective termite prevention methods in Pretoria.

Every treatment comes with a 5-year guarantee and a compliance certificate for the foundation of the house or building treated. With our proven process, you can be confident that your structure is fully protected against termites.
