To Whom this concerns:
We have reviewed the attached photos with noted- redlined descriptions showing the partial
filling of "CMU Chair Blocks" for the referenced project now under construction. We approve
of having a "cold joint" at the chair blocks and not requiring the slab on grade concrete to be
poured at the same time as the stem wall CMU cells (ref.: detail Al on sheet 7) under the
following conditions:
1) At the exterior stem walls where there ill be a wall above, roughen the existing, partially
file concrete in the chair blocks and clean the concrete surface and apply a bonding agent
such as Weld Crete. Then pour the slab on grade.
2) At doorways, install additional 90 degree bent rebar dowels with epoxy cement into the
existing partially poured concrete (#3 or #4 bent rebars) 2' (24") on center and extend
16" into the slab on grade.
If you should have any questions regarding this memo please feel free to call or email me at the
above telephone number and/or email address.
