RE: pool pour joints

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Yes, you do need to be concerned.  The tile people should put a joint
aligned with your joint.  They should also have joints about 12' on center
in both direction in their tile according to the Tile Council of America.
If they don't the tile will expand as it takes on moisture and will
delaminate from the substrate.  Did you put enough horizontal reinforcement
in your walls to allow for 40' between joints?  Is their reinforcement at
both faces of the wall?  Did you put water stops in all the joints?

Subject:	pool pour joints

do i need to be concerned about potential for cracking of pool plaster at
pour joints at wall and slab joints for a structural swimming pool?  I have
a
pool that is 8' wide x 80' long, with 12" thick walls and base slab that has
a concrete deck cantilevered from the top of the pool wall. there are keyed
joints between the deck and the wall, and at about the mid length of the
pool
 in the wall and slab.The exterior walls of the pool will be exposed and the
entire pool will be formed and cast concrete.  due to the size of the pool,
it cannot be placed in a single pour.  i have detailed keys at pour joints
with reinforcing running continuously through the joints.  The pool is one
of
the first elements that will be constructed along with the building
foundations, and it will be several months to a year before the pool is
plastered and finished.

thanks in advance-
