Regina from Pittsboro, Nc writes,

Will Timbor work if sprayed on gravel before concrete is poured for a slab-on-grade floor?

There will be EPS foam insulation placed over the gravel then 6 mil poly sheathing, then the concrete pour. Or would it be better to spray the bottom side of the foam instead of the gravel?


Is this for general insect control? We have a few more questions to accuractly answer your questions. Please call us at 866-581-7378 so that we can better assist you.
