So you can't remove slate and side view of said patio connects to concrete steps and the makeup of said patio looks like rock/concrete. I notice subterranean terminated along side surface of patio. Will drill down through top of patio through slate reach the intended termites?
To treat areas with Termidor SC that have a soil to foundation interruption such as a patio, you would drill holes in the patio using a ½ diameter concrete drill bit that is 18-24 inches long. The holes will be drilled every 12 inches and filled at a rate of 4 gallons of finished solution every 10 feet, just like you were doing in the trench.
