According to the manufacturer, Boracare with Mold Care mixtures are only for use on raw wood and no other surfaces. If you need to treat the concrete footers where the supporting beams and joists of the homes structure will rest/touch, you can apply the regular Boracare to those areas per its label instructions.
The Boracare Product Label states: Crawl Spaces and/or Basements: Apply 1 coat of a 1:1 Bora-Care solution in a 2 foot high uninterrupted band to the point of surface saturation to all structural surfaces in crawl spaces and basements, to include all sills, plates, floor joists, piers, girders and subfloors as well as structural wood exposed to direct vertical access from the soil. To prevent termite shelter tubes on crawl space or basement walls, apply a 1:1 Bora-Care solution to crawl space concrete or block walls in a 2 foot band up from the ground on interior wall surfaces. Apply at the rate of 1 gallon to up to 400 square feet of surface area. Treat a 2-foot band around construction materials and structural wood adjacent to plumbing, electrical conduit and ducts where they penetrate subfloors, if they provide a direct vertical access from the soil. Treat all structural wood, in finished basements where structural wood framing is immediately adjacent to the exterior foundation walls. Spray the concrete slab surface a minimum of 2 to a maximum of 8 inches
