Before installing, locate joints for PRO-KEY™ as indicated on drawings,
as called for in specifications or as recommended by either ACI or PCA.
Step One:
With elevation checked by instrument, stretch a line the length of
the joint 1/4" to 3/8" below the finished elevation. If cap is used,
drive stakes 3/16" deeper.
Step Two:
Place the 10' sections of PRO-KEY™ along the line end to end, using
stake slots as template to position stakes.
Install stakes on 2' centers, 5 stakes per 10' section. Small stake
slot found at each end allows stake to double as a butt splice. Additional
stakes shall be used with the remaining slots for support if soil conditions
require.
Step Three:
Hang key joint on stakes and push downward. Stake hooks slip through
lower slots and top locks into upper slots. (A patented, positive stake
to key locking system) PRO-KEY™ and stakes are punched with wire holes
if needed.
Step Four:
With continuous placement, concrete shall be placed to full
depth simultaneously on both sides of joint. When PRO-KEY™
is used as a bulkhead or in a construction joint, knockouts shall be bent at 45 degrees into the concrete.
Step Five:
Finish the concrete flush to the top edge of the key joint. Be sure the concrete fills key without void or honeycomb.
Do not edge joint!
