Waterproofing material containing bentonite

Claim 1

A coating material for waterproofing constructed structures comprising an initial mixture of sodium montmorillonite bentonite saturated with a fluidizing material selected from the group consisting of liquid aliphatic or alicyclic hydrocarbon compounds, and a non-aqueous adhesive agent not displaceable by water ranging between five to ten percent by weight of the coating material, said non-aqueous adhesive agent causing a bond between the bentonite particles without displacing the liquid fluidizer agent and without penetrating the particles, the coating material comprising between 20 to 25 pounds of fluidizing agent to 100 pounds of bentonite.

Claim 10

A method of mixing a bentonite waterproofing composition for constructed structures comprises the steps of adding in the range of 15 to 20 percent by weight of a liquid non-polar hydrocarbon fluidizing agent to a sufficient quantity of unhydrated fine granular bentonite to saturate the bentonite and mixing the bentonite and fluidizing agent together, subsequently mixing after saturation of the bentonite with the fluidizing agent an adhesive agent comprising a hydrocarbon resin having a softening point between 70° C. and 120° C. liquefied with approximately five percent by weight of said fluidizing agent to form a substantially homogeneous mixture wherein the bentonite particles tend to adhere together from action of the adhesive agent and with the fluidizing agent inhibiting the penetration of the bentonite by the adhesive agent and without displacing the fluidizer from within the bentonite particles, and adding thickeners as desired.

Claim 12

The method of mixing a waterproofing composition having a bentonite particle base for constructed structures, the method comprising initially mixing together of a non-polar liquid fluidizer selected from the group consisting of liquid aliphatic or alicyclic hydrocarbon compounds with particulate bentonite of between 200 and 325 U.S. standard mesh until the bentonite particles are saturated with the liquid fluidizer, and mixed at a rate of approximately 15 pounds of the liquid fluidizer to 100 pounds of bentonite, adding after saturation of the bentonite particles with the fluidizing agent a further mixture of between five to ten pounds of a non-aqueous adhesive material having the properties of isobutylene, up to one pound of a plasticizer, and five to ten additional pounds of the liquid fluidizer with the fluidizing agent inhibiting penetration of the bentonite by the adhesive agent, and after thoroughly mixing adding suitable thickening agents to reach a desired consistency, said thickening agents being selected from fumed silica for added abrasion resistance and bentones.
