Abstract: In some embodiments, a form assembly is provided with a form member facing an existing wall, to which sheathing panels are attached. The cavity created between the sheathing panels and the existing wall can be filled with a foamable, adhesive material which adheres to the sheathing panels and the existing wall and creates an adhesive connection between them. In some embodiments, the form assembly is vertically adjustable to facilitate the installation of multiple rows of sheathing panels. In some embodiments, the foamable, adhesive material is introduced in successive layers.

Abstract: Systems and methods for modifying existing walls are disclosed. In certain embodiments, a masonry wall is constructed near an existing wall, and the cavity between the two walls is filled with a foamable, adhesive material. The foamable, adhesive material adheres to both walls, creating an adhesive connection between them. Certain embodiments create multiple layers of the foamable, adhesive material, allowing each layer to expand before the next is introduced. Certain embodiments utilize a brush device to reduce the amount of mortar left between the two walls. Certain embodiments utilize clips for temporarily securing the masonry wall to the existing wall.

Abstract: Reinforced wall structures and methods for strengthening wall structures to more effectively resist damage produced by seismically induced forces are disclosed. According to one embodiment, a method for strengthening a double wall structure comprises forming plural layers of a foamable, adhesive material in the cavity between the two wall portions of the double wall structure to bond together the wall portions. According to another embodiment, a method for strengthening a single wall comprises spacing a sheathing layer from one surface of the wall so as to define a cavity therebetween. A plurality of structural members are positioned outside of the cavity so as to support the inner form. A foamable, adhesive material is introduced into the cavity to bond together the inner form and the wall.
