Abstract: The present disclosure provides a method for reinforcing irregular rock or irregular concrete surfaces such as rock structures in mines as well as other rock and concrete structures. The method includes applying a curable foam composition to at least a portion of a surface, at least partially curing the curable foam composition to form a foam layer adhered to the surface, applying a curable reinforcing composition onto at least a portion of the foam layer, and at least partially curing the curable reinforcing composition to form a reinforcing layer, wherein at least a portion of the reinforcing layer is adhered to the foam layer.

Abstract: A system and method are provided for automatically warming a grip surface, such as handlebars, of a vehicle in which the grip surface and a rider's hand are exposed to outdoor environmental conditions. The system has an electrical power source; a resistive heating element mounted to the grip surface for warming the grip surface; an automatic temperature controller having a switch electrically connected in series between the power source and the heating element for switching power on and off to the heating element in response to a temperature feedback signal; and, a temperature sensor electrically connected to the temperature controller for providing the temperature feedback signal and mounted on the grip surface at an interface between the grip surface and the hand, the grip surface and the hand being exposed to outdoor environmental conditions. The system is particularly useful for vehicles such as snowmobiles, snow throwers, ATV's and motorcycles.
