A composite foam and concrete wall includes a foam layer having a top surface, a bottom surface, a left wall surface and a right wall surface wherein the foam layer comprises at least two foam panels that define a seam that is substantially parallel to the top surface and the bottom surface. A concrete layer is secured to a surface of the foam layer.

A polyurethane foam block can include a base having a plurality of recesses and a top surface having a plurality of connective components protruding outward from the top surface where each connective component of the plurality of connective components can align with a recess of the plurality of recesses. The polyurethane foam block can include a plurality of sidewalls extending upward from the base and defining an interior and a plurality of partitions extending from the base to the top surface to divide the block into a plurality of cavities. A wall can include base blocks and header blocks. The header blocks can be shaped and constructed similarly to the base blocks with one exception being the header blocks can include an-upward facing channel cutout. The wall can include a beam extending through channels of header blocks.

A portable grout device is provided. The device includes a grout hopper, a cylindrical tube portion connected to and operable to receive grout from the grout hopper, and a drive shaft and auger assembly within the cylindrical tube portion. The drive shaft and auger assembly includes a central shaft and a helical auger screw operable to push the grout out of an end of the cylindrical tube portion.

Concrete wall supports that reduce or eliminate wall movement due to exterior horizontal forces. One support is a bracket mounted to a floor joist with a plate extending below the top of the wall and two legs extending from the plate and attaching to the joist. One leg is above the concrete wall on one horizontal side of the plate, and the other leg is on the opposite side of the plate. Another support has a plate that extends below the top of the wall with two legs on opposite sides of the joist above the wall. A leg attaches to the lower edge of the joist. A support against shear forces includes a highly water permeable aggregate composite disposed in the voids of the wall, with a supportive strip that is enclosed in the aggregate composite and extends out of the voids to the face of the wall.

Various implementations are directed to a single face building block and masonry wall assembly and methods. Each building block includes a single face shell, first and second webs extending from an interior surface of the face shell, and a pier that has a proximal surface disposed between distal ends of the webs and a distal surface that is opposite and spaced apart from the proximal surface of the pier. Interior surfaces of the webs, the proximal surface of the pier, and a portion of the interior surface of the face shell between the webs define a pocket. In addition, the building blocks may include a ledge that extends outwardly from the distal surface of the pier. This ledge forms a channel with an upper surface of the pier stacked above the block.
