Method of multiple injection

Claim 1

A method of simultaneously termite-proofing and waterproofing the soil about the foundation of a building which comprises simultaneously inserting along a single plane at desired intervals into the soil to be treated a plurality of probes connected to a single manifold, said probes being urged into the soil by a downward force applied to said manifold, simultaneously pumping a termite-proofing liquid and a waterproofing liquid through said single mAnifold and said plurality of probes into the soil to be treated without intermixing the two liquids in the manifold or the probes, one of said liquids being pumped through a first plurality of said probes and the other of said liquids being pumped through a different plurality of said probes, and then removing said probes from the soil and repeating the aforementioned steps until the circumference of the building has been so treated.
