Jeff from Baton Rouge, La writes
I've got 700 square feet of pressure treated wood porches running the full width of my house on the front and rear. These block my access to trench and treat the soil on roughly 1/2 of the perimiter of my house. They're very low (2-6" off of the ground). Unfortunately the boards run perpendicular to the house so removing them to gain access to the soil for treatment would mean almost complete disassembly and rebuild of the porches. Could I treat these in the same manner as a concrete porch? Drill down through the porch every 1' near the slab with a long bit and then feed a pump sprayer wand down the hole to inject the solution?
While trenching is always the best option for full protection, something is always going to be better than nothing. If you can drill through and treat the area like you would a concrete slab, this would be great to do. You will want to pour heavier amounts of the product into the holes and even down the side of the foundation between it and the first plank to try and soak the soil below for better coverage. If you do this you should be able to adequately protect the home. If the home is on a crawl space i would suggest going under the home and trenching on the inner wall of the crawl space as well.
