A concrete form for holding a concrete product in place during a curing process with at least one side movable by a rotary driven power source and a actuator. A rotary power tool with a helical cutout combinable to a second adapter on the rotary driven power source to rotate the rotary driven power source to power the actuator and move the at least one side.

The present disclosure generally pertains to blocks for building landscape walls and similar structures, the molds used to make the blocks, and the methods for making the blocks. Such block can be securely coupled to another block. A block can be vertically coupled to another block by coupling the dorsal face of one block to the ventral face of another block. The block can be horizontally coupled by coupling the male side of one block to the female side of another block. A secure, exemplary landscape wall may be created by coupling the blocks both horizontally and vertically to reach a desired height, width, and shape.

A permeable surface covering unit comprises a top surface and at least two pairs of irregularly shaped mating sides, one or more passageways extending downwardly from the top surface, and at least one under channel connected to the passageways for retaining liquid, such as storm water. The sides of the unit preferably define an irregular rotational tessellation element. The passageways may comprise gaps or side cavities between units and/or core cavities or other passageways within the unit. Optional undercuts may be provided in the core cavities. Pervious material plugs are cast into the cavities extending into the channel or undercut. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces. A permeable surface embodiment comprises a combination of pervious and impervious units, wherein the ratio of permeable to impermeable units and resulting surface absorption rate may be adjusted.

A permeable surface covering unit comprises a top surface, a bottom surface and at least two pairs of sides. A cavity is formed in the unit from the top surface to the bottom surface, and has side walls. The cavity may be a side cavity between units and/or a core cavity within the unit. An undercut is provided in the cavity. Pervious material plugs fill the cavity and extend into the undercut. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces.

Devices and methods for forming voids or cavities in concrete such that reinforcing bars can be used to connect different pours of concrete, the devices including an insert having a base and an elongate member extending from the base, and the method including coupling the insert to formwork, pouring concrete into the formwork, which surrounds the insert, allowing the concrete to partially cure, such that it retains its shape, removing the formwork and insert to form a void in the partially cured concrete, inserting a reinforcing bar into the void, applying adhesive to adhere the reinforcing bar to the concrete, and pouring concrete around the reinforcing bar, such that the reinforcing bar joins the two pours of concrete together via the void and adhesive.

The concrete garden bed mold is plastic mold that creates concrete walls for a garden bed. An objective of the concrete garden bed mold is to provide users with a mold that easily releases the concrete block once cured within the mold. The concrete garden bed mold intends to provide users with a device that can create concrete molds with cylindrical holes to allow for a securing rebar to traverse through the concrete, securing the wall in place. To accomplish this the concrete garden bed mold has a mold cavity, a flat top surface, and tapered walls. The tapered walls ensure the created interlocking garden bed wall does not get stuck within the mold cavity as the concrete cures.
