945-1 Articulated Concrete Block Detail
3.3 STANDARD & OPTIONAL BLOCK LAYING METHODS
To initiate block lay, start with a straight line perpendicular to direction of lay.
Maintain straight line block lay proceeds across slope.
Watch orientation or rotation of individual units as a small error in laying can progress in severity as lay block proceeds. To maintain straight lines it is best to lay no more than two rows at a time.
Block pairs are generally easiest to install by placing lock block into key block then rotating block pair until key fits into adjoining lock block. Always lay towards an open area and not toward a point of fixity.
If laying adjacent to a pavement or similar structure this option may be pursued to achieve a more aesthetic appearance.
STANDARD BLOCK LAY METHOD
N.T.S.
OPTIONAL BLOCK LAY METHOD
N.T.S.
Blocks are normally delivered to Job site on pallets with blocks stacked in pairs.
Block lay can proceed equally as well In either direction.
To negotiate tums or curves in the slope step the blocks up or down as required. Maintain continuity of straight lines.
If unevenness of slope or other circumstances prevents the block from interlocking, a new block line may be started.
The resulting joint or seam should be grouted with concrete.

3.6 90-DEGREE CORNER •
DIAGRAM c-e
DIRECTION OF MAT LAY ---
Vertically of leading edge coming out of a comer depends on side slope and angle of tum; but in no case can it differ more than 30 degrees from vertical because of triangular design.
To maintain horizontal line stepping up or down of block may be required.
A joint can be avoided when hand placing blocks on the slope: but a reorientation of the triangular blocks (or leading edge) does occur.
