Disclosed herein is a temporary wellbore sealant, comprising water, a gelling agent; and a filler, wherein: the filler has a lower specific gravity than the water of the sealant; and the sealant has a lower specific heat than the water of the sealant and a method of temporarily sealing a liquid filled wellbore therewith.

The invention relates to a method for providing an underground barrier for a water flow. The method includes the steps of drilling in soil a number of parallel vertical holes; inserting pipe strings into the drilled holes, where each pipe string has a pipe string wall with a plurality of openings arranged distributed along the length of the pipe string; introducing injector means in each of the pipe strings; positioning the injector means at a plurality of discrete depths in the respective pipe string and aligned at each depth with at least one of the openings in the pipe string wall; and injecting at each discrete depth a sealing compound, such as sodium silicate, through the at least one aligned opening into the soil.

A method for stabilizing a slab foundation comprises a narrow, vertical moisture barrier assembly spaced outside and surrounding the perimeter grade beam of the slab foundation by a predetermined distance, and extends to preferably five feet below surface grade. The narrow trench for the barrier is preferably less than three inches wide. A membrane formed of a synthetic composition forms a moisture barrier against one wall of the narrow trench, and is held in place by back fill. The moisture barrier is intended for use in expansive soils that are subject to shrinking and swelling.

This invention relates to a method for insulating sub-soil comprising mechanically destructuring the sub-soil, injecting an insulating material into the destructured sub-soil, and mixing the sub-soil and the insulating material. The thermal conductivity of the insulating material is strictly lower than the thermal conductivity of the sub-soil.

A method of soil treatment that allows for the creation of or installation of a highly reflective surface for use in conjunction with bifacial solar panels to more efficiently generate clean energy.
