Which type of slab-on-ground construction is most susceptible to termite attack?

Floating slab-on-ground construction is particularly susceptible to termite attack primarily due to its design and the conditions it creates. A floating slab typically does not have a continuous footing beneath it, allowing for gaps and voids where moisture can accumulate. These conditions can attract termites, which thrive in damp environments.

Additionally, floating slabs often have direct contact with the ground without sufficient barrier protections, such as termite shields or treated soil. This direct contact increases the risk of termite infestation, as the insects can easily access the wood components of the house above.

In contrast, other types of slab-on-ground construction, such as monolithic slabs or precast slabs, typically involve more integral structures that can be designed to minimize direct ground contact and provide better protection against termites. Therefore, the floating slab’s vulnerability stems from its construction method and the potential for moisture retention, making it a prime target for termite activity.
