A pocket former may include a pocket former body, the pocket former body having an outer surface. The pocket former may further include a collapsible element, the collapsible element formed on the outer surface of the pocket former body. The collapsible element may extend radially outwardly from the pocket former body.

A post sleeve provides a substantially permanent base for supporting a post for a fence or sign, and from which one post can be removed and replaced with another post. The sleeve includes a concrete body that is poured on site, using a sleeve core prepositioned in the post hole, and around which wet concrete is poured. After the concrete is cured, the core is removed, leaving a post sleeve cavity configured to receive a post. The core can be rigid, or can include a flexible shell and stiffener. A preformed post sleeve top can be attached to the sleeve core and positioned therewith in the post hole, to become a permanent part of the post sleeve, once the concrete cures. A drain is attached to the core, and remains in the sleeve when the core is removed, and can be a percolation chamber, or passage extending below the sleeve.

A reusable form for creating conduit paths in concrete slabs is described. The form comprises a flexible tube that is positioned prior to pouring a concrete slab. The form includes a keep to keep material out of the hole formed by the form. The form also includes a key structure to permit easy removal of the form once the concrete is set. The system further includes a sighting device to permit rapid and precise alignment for placement of a form when forming conduits in a multi-level building. An accessory is also provided permitting filling in the opening created by the form once wiring, piping and other objects have been installed within the conduit.

A pocket former includes a pocket former body and a keyway former. The pocket former is adapted to form a void in a concrete member allowing access to the stressing end of a post-tensioning tendon. The keyway former is adapted to form a keyway in the concrete to allow grout to be more securely retained in the void.
