A process for coating geological formations and mine stoppings by applying to these substrates an aqueous, non-cementitious sealant composition comprising a water-soluble or water-dispersible polymeric binder, filler material and water, and allowing the sealant composition to dry to form an air flow resistant coating on the substrates. A highly satisfactory polymeric binder is used in the form of a polymer emulsion, such as an emulsion of an acrylic polymer having a low Tg and being sufficiently plasticized to provide a coating having prolonged air flow resistance.

Mine stopping sealant

A stopping for use in improving underground mine ventilation comprising an assembly of wall elements, said wall elements comprising:

Foam slabs in mine tunnel stoppings

A building structure comprising a corrugated protective layer having crests and valleys, a plurality of rigid metal securement strips applied over the corrugated protective layer, an outer weather-resistant covering applied over the rigid metal securement strips, and connecting means for securing said building elements together. A layer of insulation may be included between the rigid metal securement strips and exterior weather-resistant covering. The outer weather-resistant covering, the layer of insulation, and the metal securement strips can be secured to the corrugated protective layer without disturbing the preexisting structure.

Structure for retrofitting corrugated building exteriors

An insulating wall structure for installation over an existing outer wall of a structure comprises an insulating material spaced from said outer wall with a closure means at the bottom and sides of said outer wall and an opening adjacent the top of said insulating wall structure.

Vented insulation system for existing structure

A novel and highly efficient insulating wall structure for a building comprises a generally closed wall with a top venting structure only. The wall structure generally comprises two substantially moisture and air impervious barriers spaced from each other by intervening framing members, a bottom substantially moisture-and-air impervious closure sealing the bottom of said barriers and a venting structure locating only at the top of said wall to release water vapor from the interior of said wall.
