This article examines the effectiveness of foundation concrete slabs
in preventing termite attack on wooden roof trusses. Twenty residential bungalow
buildings, constructed with hollow sandcrete blocks, were investigated for a period
of 5 years. The buildings were grouped into four. The fi rst group belongs to buildings
without foundation concrete slabs; the second group is buildings with foundation
concrete slab constructed from bush gravel. The third group of buildings has their
foundation slabs constructed with crushed granite, manually mixed, while the fourth
group belongs to buildings with foundation concrete slab constructed from crushed
granite but mechanically mixed. It was discovered that the fourth group of buildings
had 100 per cent proof against termite penetration, the third group of buildings had
high resistance to termite penetration, but not 100 per cent, while the second group
of buildings had limited resistance to termite penetration, and the fi rst group of
buildings had no resistance against termite penetration
