Abstract: A foundation pile installation system includes a hollow foundation pile having a pair of cooperating tapered drive pin slots at its top end and a pair of drive pin holes spaced below and aligned with the drive pin slots, first and second drive pins, a drive head having a drive collar and a flared lid, the drive collar having top and bottom drive pin holes, the drive collar for insertion in the top end of the pile in an assembled configuration in which the first drive pin inserted in the top drive pin holes of the drive collar is received in the drive pin slots of the pile and the second drive inserted in the bottom drive pin holes of the drive collar is received in the drive pin holes of the pile to secure the drive head to the pile, the tapered drive pin slots guiding the first drive pin into the slots as the drive head is inserted in the pile.

Abstract: A dry-stack masonry wall supported on hollow piles includes a wall having a plurality of stacked rows of masonry blocks that form a hollow interior grid of horizontal and vertical channels. The wall is supported on piles having hollow interiors, each of which is in communication with one of the vertical channels of the wall. Hardened grout filling the grid of the wall and the interiors of the piles monolithically binds the blocks into a wall which is bonded to and supported by the piles.

Abstract: The present invention generally relates to a precision dry-stack masonry unit made of two spaced-apart face shells and at least one connector joining the face shells. The connector has a top surface, a right surface and a left surface. The top surface of the connector and the face shells form a horizontal channel above the connector, and the right surface and the left surface of the connector and the face shells form vertical channels to each side of the connector. Each of the channels is configured to accommodate one or more reinforcement bars.

Abstract: The invention described herein is a fence post bracket for inserting into a retaining wall or other structure capable of securely holding a fence post. The fence post bracket offsets the placement of the fence post from the center of the retaining wall so that the fence post placement is on the actual perimeter of the wall and not in the center. This results in a significant increase in usable land for large fenced area.
