Service Overview
Soil treatment is a chemical barrier method applied to the soil around and beneath a structure to block subterranean termite entry. It is one of the oldest and most established termite control methods and remains the standard for both pre-construction and post-construction perimeter defence in Malaysian buildings. In post-construction application, the treatment is delivered through drilled holes in the concrete slab, along the foundation perimeter, or at known entry points. The termiticide is injected under pressure to form a continuous treated zone in the soil. In pre-construction application, the termiticide is sprayed directly onto the prepared soil before the concrete slab is poured, creating a barrier that termites cannot cross without being exposed to the active ingredient. Soil treatment is suitable for both corrective and preventive use, depending on the construction stage and site condition. Corrective application targets known entry points and creates a fresh barrier where the original barrier has degraded. Preventive application at pre-construction stage is significantly more cost-effective than post-construction treatment, which is why builder coordination matters. Treatment effect typically lasts 5 to 8 years depending on soil type, moisture, and termiticide used.
If you are building, planning a renovation that exposes the foundation, or seeing new entry points in an older property, request a site visit. We will assess soil conditions, construction stage, and infestation pattern to recommend the right treatment scope and timeline.
Barrier method
Targets structural entry routes with controlled termiticide application.
Corrective or preventive
Can be used after termite signs are found or as pre-emptive protection.
Technical execution
Application quality affects durability and effectiveness.
Site-specific planning
Soil condition and layout influence treatment design and volume.
How this service works

Frequently asked questions
How long does soil treatment last?
Modern termiticides applied at correct dosage typically remain effective for 5 to 8 years in Malaysian soil conditions. Heavy rain, high water table, or soil disturbance can shorten this. Annual inspection is recommended to confirm barrier integrity.
Is soil treatment disruptive?
Pre-construction soil treatment is non-disruptive because the slab has not been poured. Post-construction treatment requires drilling through concrete at intervals, which produces some noise and dust but is normally completed within a day for a typical terrace or apartment unit.
What is the difference between pre-construction and post-construction soil treatment?
Pre-construction treatment is sprayed directly onto the prepared soil before the slab is poured, creating a complete barrier. Post-construction treatment is injected through drilled holes in the existing slab, which is more disruptive and can only treat specific zones rather than the full footprint.
Can soil treatment be done in rainy season?
Soil treatment is best done in dry conditions so the termiticide binds to the soil matrix. Heavy rain during or immediately after application can dilute the treatment and reduce effectiveness. Treatment is scheduled based on the weather forecast.
How is dosage calculated?
Dosage is calculated based on linear metres of perimeter, depth of treatment zone, and soil type. The Malaysian standard requires a continuous treated zone of at least 300mm depth for foundation barriers. We document the dosage used in the post-treatment report.
