I am not sure what you are referring to as a "pole building". However, the type of slab you are referring to is normally called a "floating slab". The slab cement simply floats inside of the outer foundation walls.
If the termites are entering the building through the enterior slab "expansion joint", where the cement is separated from the outer wall, then there are 2 options.
1. If the expansion joint or crack is wide enough, apply Termidor to the crack directly. Apply as much as the crack will hold, let it sit and soak in, then reapply 2-3 times.
2. Drill holes along the cement expansion joint and apply the Termidor through the holes. The idea is to drill holes through the cement to apply the chemical into the soil below.
This is done normally by drilling a 1/2" hole with a hammer drill and a 1/2" concrete drill bit which can be rented at any tool rental place. The holes are usually drilled about 6 inches from the joint and every 12" -18" down the entire length of the joint. Sweep up the cement dust before applying Termidor.
Most pest control companies use a special tool called a "slab injector" that is placed into the hole and the Termidor is pumped under the slab this way. You can also use a funnel and pour the Termidor into the hole. The rate of application is 4 gallons per 10 linear feet.
After application use Trebor plugs and seal the hole. Push the plug about 1/2" inch into the hole and then use a small dab of cement and "patch the hole". Here is the link to Trebor plugs - http://www.epestsupply.com/product/TR...
