ABSTRACT:
A hydration system having one or more units (10, 10', 10") for providing a continuous flow of water to newly placed concrete has a plurality of spaced elongated soaker tubes (12) extending parallel to a longitudinal axis (14) of the unit. Respective manifold tubes (16-19) are attached to each end of soaker tubes (12) and a supply coupler (32) is in turn attached to the manifold tubes at one end of the unit and an additional coupler (34) is attached to the manifold tubes at the opposite end of the unit. An upper impervious layer (28) is disposed over the tubes (12, 16-19) and a lower pervious layer (28) is disposed under the tubes (12, 16-19). Layers (26, 28) are attached to each other along the outer periphery of the unit and on opposite sides of the tubes by rivets (30) or stitching (42). A skirt (36) provided with spaced grommets (38) in one embodiment and hook and loop material (40) in another embodiment is disposed along the outer periphery of the unit to facilitate attachment to contiguous hydration units.
