Treatment of Voids in Masonry

It has been seen which termites enter within masonry foundations from soil adjacent, beneath the building and work their way up by voids in the masonry joints and gain entry within the interior of the buildings. To avoid the entry of the termites by voids in masonry, 12 mm diameter holes at 300 mm centre to centre are drilled at downward angle of about 45o from both sides of walls at plinth level and then chemical emulsion is pumped within the holes until masonry gets fully saturated along with the chemical emulsion. The holes are then sealed. This treatment is carried out for all walls (both internal as well as external) having foundation in soil. Treatment of drilling hole and pumping chemical emulsion should also be carried out at critical locations such as wall corners and at places whereas door and window frames are embedded in masonry in ground floor.
