A concrete form system includes a plurality of concrete form board brackets. The plurality of brackets includes brackets for securing the concrete form board to a conventional type metal or wood concrete form stake without the need for nails. The plurality of brackets also includes concrete form board end brackets for securing the ends of adjacent concrete form boards together that allows for a range of angles to be formed between two adjacent concrete form boards from zero degrees to more than 180 degrees. The present invention also includes flexible sections of concrete forms configured to be coupled to the brackets that allow for forming curved concrete edges.

The invention comprises a method of forming a slab on grade. The method comprises placing a first layer of insulating material horizontally on the ground and placing plastic concrete for a slab on grade on the first layer of insulating material. The plastic concrete is then formed into a desired shape having a top and sides. A second layer of insulating material is placed on the top of the plastic concrete and the first and second layers of insulating material are left in place until the concrete is at least partially cured. The second layer of insulating material is then removed. The product made by the method is also disclosed. A slab on grade is also disclosed.

A casting kit for constructing a foundation which includes a plurality of void forming members, each of which has securing means on its sides to secure to a matched void forming member thereby to define a minor void forming formation and at least one side of each void forming member having a step formation such that a groove is formed between the step formation of adjacent void forming members in a minor void forming formation for receiving tensile elements in the groove.

The present invention is directed to a flexible concrete form system having both flexible and rigid parts that are easily assembled and disassembled using a multi-contact point connection system. The concrete form system can be extended or stacked in a wide variety of configurations to accommodate almost any desired concrete shape.

A sealing structure for the bottom of a beam space between precast panels, comprising: a first precast panel and a second precast panel substantially aligned to each other along a single plane and spaced from each other by a space, each of the first precast panel and the second precast panel defining an inner edge adjacent to the space; a soft pad abutting the space for sealing a bottom of the space; a plate abutting the soft pad; a fastening device securing a first side of the plate and a second side of the plate to the first precast panel and second precast panel, respectively, so as to assist the soft pad in the sealing of the bottom of the beam space; wherein the fastening device does not contact the soft pad.
