Tooled Joints in Slabs on Ground
Tooled Joints in Slabs on Ground
(OP)
I am looking for a resource to develop a detail for tooled joints in a slab on ground. In most places the slab will be only 4" thick. The application is in a office building. The architect does not want to use saw cut joints.
Does any know of a good article on this? Would anyone be willing to share a detail they have successfully used?

good concrete finishers routinely hand tool joints in SOG's using finishing tools and extension poles.
I always had my finishers hand tool a joint in the slab as soon as it was poured to keep the aspect ratio below 1:1.5.
A decent hand tooled joint should mitigate T&S cracks.
Then I make sure that they come back and saw cut the hand tooled joint down to 1/3 the depth of the concrete as soon as they can get back on the concrete with a saw.
You cannot see the cut down inside the hand tooled joint.

For the extra cost of hand tooling the joints the architect better not put carpeting on top.

Sawcut are pretty clean looking when exposed (my opinion)... I also wonder why the architect cares since most if not all slabs in office buildings are covered with some kind of a finish. The architect should be more concerned about the layout of slab joints, particularly where there is thinset ceramic tile. Nothing like a huge crack in the tile through the middle of your elevator lobby.

Notes:
** Tooled joint depth shall be a minimum of 20% of
the total floor slab thickness.
