I am seeing too many cases of homes in the 30-day and 1-year warranty periods of the TARION warranty where a simple PDI performed by a qualified Home Inspector could have saved the buyers from a lot of aggravation in dealing with the Builder/TARION Warranty corporation after the home has closed.
And I’m pretty certain ABS is not compliant to the IPEX 081216, IPEX 081218, and IPEX 081219 standards (PVC/CPVC) required for Canadian fitting in the Payne Installation Instructions, but I’m double checking.
Thanks, and to be perfectly honest, without the additional supplied information, I had no idea what your photo’s were showing in relation to what was in your mind. The bedroom ceiling pic’s could have been the light fixtures, of which some AHJ’s do not allow in my area for safety reasons. (I remember breaking many as a child, especially when shot with a water gun)!
Typically/unfortunately many home inspectors do not get to see could pour joints.
Even with a PDI inspection, cold pour joints can be explained away as normal unless you have the training required to assess the concrete seam.
A cold pour joint is where successive pours or placements of concrete abut during building construction, are normal, but on occasion are leak points that may need sealing or lastly repairs.
If the home is protected with delta ms, blue skin or anti damp product, it will take many years, if not decades, for water mitigation below the soil through cold pour joints.
There is a difference between a cold-joint and a cold-pour joint.
Cold-joints are quite common where extensions to existing cement structures are added to.
A cold-pour-joint is just as common, although proper planning should minimise the risk of it happening, where the cement truck runs out of cement and the existing pour starts to cure before the next load is ready to be poured so it fails to get a good interlock, or the two loads are at different slumps so they cure inconsistently.
One would NEVER, nor should not EVER, put a membrane between the two pours.
A method of joining two separate pours is to scabble the existing concrete so you get a good aggregate interlock with the new pour to the old.
ANY cold joint that has not been properly interlocked is susceptible to leaking, with the lower areas of the joint likely to leak first (because of the physics behind hydro-static pressures)
As for water proofing, Blue-skin would certainly provide protection against water intrusion, but Delta-MS is not a waterproofing membrane. It’s a protective drainage membrane that manages water but is not waterproof because of the joints. It is designed to allow water to migrate out of the poured foundation wall to the outside of the property and down into the perimeter drain.
If it was water proof they’d offer more than a 7 year warranty on it.
You see Len, that’s what happens when someone who doesn’t know what the hell they’re talking about, goes looking for info to “Clip & Paste” to make themselves appear knowledgable to those that don’t know any better!
Generally, cold jointsare not a problem structurally if the joint is in compression. However, the location of the joint within the structure, the structural function of the element and aesthetics need to be considered when assessing a cold joint.
