Basement wall @ slab on grade
Basement wall @ slab on grade
(OP)
Typically there is exp joint/bond break between slab-on-grade & bottom of the basement wall. Yet, the wall is assumed to be pinned at this location (not designed as cantilevered). Does this mean that the joint/bond break is assumed to be compressed to the point where the force is transferred into SOG?

Today, many engineers, like hokie, avoid a soft joint so the wall movement is limited to the amount of slab shrinkage.
There does not appear to be a problem with either detail.

I have doweled the slab to the wall in the case of ICF walls due to this issue where the form is 2+" thick and the contractor doesn't want to remove/cut the forms (and ties).

The purpose of a soft joint in an interior slab on grade is not to allow movement perpendicular to the wall, but parallel to it, thus limiting restraint which leads to shrinkage cracking. The soft joints are used frequently because they are easy to install, but turning the plastic up will do the same thing. If in an exterior situation where debris is likely to accumulate, then a joint for movement perpendicular to an obstruction like a wall or curb is necessary.

I think I need to pay more attention to this "boiler plate" detail. I can already dread the discussions with the architect bosses about why it is missing from the drawing... <shrug>.
