Concrete crack inducer with drainage channel

A device for inducing cracking and providing drainage in concrete, comprising:

• a base having a flat bottom to sit upon a bed upon which concrete is to be poured such that the device is self-standing;
• a pair of legs having a planar face extending a length upwardly from the base;
• a drain channel between the base and the legs and having at least one open end to drain fluid from the channel;
• wherein the legs initially engage one another along the planar face and then spread apart as the concrete cures so as to induce a crack in the concrete and to define a gap between the legs communicating with the drainage channel to drain moisture which enters the crack;
• wherein the drain channel is spaced above a top surface of the base;
• and a stake extending through the base to secure the device on the bed.

A device for inducing cracking and providing drainage in concrete, comprising:

• an extruded member having an integrally formed base, a pair of legs and drain channel;
• the base having a flat bottom to sit upon a bed upon which concrete is to be poured such that the device is self-standing and extends continuously across the bottom of the drain channel;
• the pair of legs each having a planar face extending a length upwardly from the base to a top edge;
• the drain channel between the base and the legs and having at least one open end to drain fluid from the channel;
• wherein the legs initially engage one another along the planar face and then spread apart as the concrete cures so as to induce a crack in the concrete and to define a gap between the legs communicating with the drainage channel to drain moisture which enters the crack;
• and
• wherein the drain channel is integrally formed into the extruded member between the base and the legs from a lower end of each of the legs to a top surface of the base which extends outwardly from a bottom of the drain channel.
