Surface Bonding

Hi folks,

I have a question about the need for surface bonding.

I am building an accessory building here in Vermont, that will sit on a slab that is poured over frost wall. I have the footing and footing drains in place, footing has rebar throughout and hook dowels.

I am starting to lay up the wall. The wall will be comprised of 12" CMUs dry laid, reinforced vertically 24" OC and horizontally 16" OC, with grouted cores. As the wall goes up, I also plan to backfill the exterior of the wall and interior, until I reach the start height of the slab.

My original plan included surface bonding both sides of the wall. But am now rethinking the necessity of that.

Thoughts?

Personal projects are frowned upon here. However, I ask "What for". See my note on your other post. Deleting these posts might be a better idea, rather then being chewed out for having the managers do the deleting.

I believe this is the frost wall you are talking about. But I don't understand "surface bonding both sides (faces) of the wall", bond to what, backfill?

retired13,

I am thinking the OP is parging on a cementatious (maybe with fibers) coating that surface bonds the dry-stacked CMU wall blocks together. Note the OP also mentioned grouting the blocks, with reinforcement, as well.

Remember more details is always better.

Surface bonding seems redundant in this case.

no need to take this in account.
