Regarding cold joints, I would believe since we are talking about Residential Buildings, is somewhat a horse of a different color as far as Design, Performance , Execution, and Quality.
You as an Engineer and me as a Commercial Builder, both know that the Control of a Residential Concrete pour is unsupervised by any of the normally expected Quality Control that we might be accustomed to seeing.
Residential Concrete Contractors as I have observed Locally and endorsed by the Concrete Supplier Drivers, typically pour concrete at about a 6-7" slump and minimize the amount of ramps they have to build to back up the trucks so they do not have to pay for a Concrete Pump. For me using a concrete Pump is a no brainier.
Considering the slump of concrete that is being used, you now have a pour line in the finished product that is visible to the HI when inspecting the basement. Yep., it is horizontal or close to it.
The slope of the pour line can mathematically be estimated as to what slump was used. If an uncoordinated effort was made to the delivery of the concrete this pour line now becomes a cold joint.
Residential Contractors usually only have one vibrator with no spare and the 1 &1/2" vibrator head they have will not cut it when it comes to cold joints. With no performance or concrete specification that most have, vibration is probably in excess to what they would do.
Forms are stripped the next day and reveal an unconsolidated pour line with exposed aggregate and an entrance gate for water from the outside.
The type of Band Aid as you call it, I call the Bituthane 4000 Manufactured by Grace. They should not attempt to rely on the most common foundation coating that I have commonly observed.
This system has worked for me for years on end and don’t have to worry to much about the crappy backfill that usually occours with the local Residential Builders., other than the frost affect and the foundation it’self. In my case it is usually stone. Maybe I should say pea stone and sound like by buddy. ha. ha.
Bottom line is that it has to be addressed from the origin point and not with sophisticated products that cost an arm an a leg and not really a guarantee either.
Cost Estimates would be prudent at that point and the client or owner can make the final decision as to what is more economical at that point.
I would persue making the proper recommendations to a client as to who in the areas would be more educationally and qualified to make the necessary repairs.
I have said enough I guess. ha. ha.
Thanks for all the good contributions you have made. It is well appreciated.
