A modular foundation assembly for building a modular foundation for a home includes a tarp that has a plurality of openings each strategically positioned on the tarp to facilitate the ground to be marked for a foundation. A plurality of concrete forms is provided which each has a trapezoidal shape. In this way each of the concrete forms can be lifted upwardly from a concrete member formed by the concrete forms when the concrete member has cured. Each of the concrete forms has a crenellated edge to form a series of slots into the concrete member. In this way the series of slots in the concrete member facilitate the concrete member to be lifted with a forklift.

A concentric-ring single-sided dovetail groove ceramic tile back mold core is disclosed. A back mold core surface vulcanized rubber comprises raised patterns and recessed patterns integrally formed, pasted and covered on a back mold core iron substrate. The raised patterns are equidistantly offset outwards layer by layer with a central position of the back mold core as a center; and a side of each raised pattern close to the center is of an equiangular obtuse angle, and a side of each raised pattern far away from the center is of an acute angle with an angular equal difference gradually decreasing.

A heavy duty retaining wall mold. The concept of invention by requiring Precast Reinforced concrete laying characteristic, when removed work piece from mold, the from face is in a face up manner. The inventions associated with this concept are comprises of three group, first are Front Panel and Rear Panel, all sizes are equal in all respect, second are left panel and right panel, all sizes are equal in all respect, and the length of them are shorter than Front and Rear Panels. Third are central parts group, which divided in to two groups, first group are on the upper part could he assemble and disassemble, second group are on the lower part of none disassemble parts. The pouring system by poured fresh concrete from the upper square Front face the vacancy area.

A barrier system is used to direct and block a travel path of pedestrians and vehicles. The barriers may be shaped substantially as a truncated pyramid with a base surface and planar sides extending from the edges of the base surface to a top portion, where the cross-sectional area of the base surface is larger than the cross-sectional area of the top portion. The angles of inclination between the planar sides and the interior of the base surface are acute angles. The bollard can be cast from heavy dense materials. The bollard includes at least two overhanging lips on the planar sides of the barrier between the base surface and the top portion. The configurations of the bollards provide improved placement, such as with cranes, hand carts, and other devices. Molds to cast the barriers and hand carts to move the barriers are also disclosed.
