Home had an interior basement system installed. The interior system was no longer being used. (I wonder why ) There were 2 sumps that were abandoned with standing water. (Stinky, smelly and nasty) Concrete floor recently painted with numerous cracks and high levels of moisture.
Exterior excavation was done and they replaced 1/2 of the one foundation wall with concrete block. Rest of foundation was Terra Cotta Bricks. Entire exterior was excavated.
My issue is with the floor. The stinky smelly water needs to be removed. I recommended the floor and pumps be evaluated.
There was mold at portions of the interior panels and since exterior was done I recommended removing all the panels.
There was an area of damaged Terra Cotta. You would think they could patch these areas when the excavation is done. 11, 000 dollars
What do you think about the floor and pumps. The water needs to be removed. I would reinstall the pump(s)
Sometimes,efflorescence etc on a basement floor could have been caused by the water/salt that is/was coming in from cracks etc on outside of the wall and just like efflorescence on basement walls, efflorescence might be BEYOND-the-surface of a wall/concrete floor thus,won`t be able to get it all off.
Also, ‘if’ there is a storm trap cleanout you might want to recommend they check it and if needed…snake it.(lateral line)
Could also snake the tiles that empty into pit just to make sure there isn`t any blockage in those tiles.
Being a pourous terra cotta foundation and having the panels cover the entire wall it is possable that the system trapped water in between the panels and the foundation therefore resulting in deterioration. There are other spots that you could see the bowing and I was really wanting to remove the panel to see what damage was behind.
But anyways I think this is a good example of why not to install an interior waterproofing system.
I don’t use a moisture meter to check the level of moisture on concrete foundations. Most concrete foundations will have a high moisture level no matter what the conditions are. Yes, even dry foundations have a high moisture content.
Foundations that seep or leak moisture are obvious and remediating these foundations all depends on the conditions that exist throughout the property. I investigate all seepage issues while I’m on-site and inform my clients which steps to take in order to properly remedy any existing seepage issues in their prospective home.
Ummmm,these inside system companies are NOT identifying WHERE the freaking water is entering,they NEVER waterproof the exterior of wall(s)…and THEY`RE experts??? huh? Chtt!!!
They dont ever recommend/bring up the possibility there can be a problem in the lateral line.ALL they want to do is bchtt people into a water----diverting system,the only damn thing they do.
When homeowners have cracks,loose cracked parging on the outside of block walls,they never fix this chtt.
What about underground roots against the outside of walls?
They never remove these.
What about the homeowners who have cracks or bowed walls due to lateral soil pressure?
They don`t remove-relieve-lessen ANY of the lateral pressure which
CAUSES alot of cracks/bowed walls…jeses kristmas.
They also create/drill freaking HOLES in block walls…not worried about
the possibility of MORE radon gas entering peoples basements?
What about mold,efflorescence? Not worried about this either…
behind that blccchtttt moronic vinyl sheeting they place against walls?
What about termites and other insects that will continue to enter exterior cracks when these morons only install inside systems.
What is professional about not identifying and correcting the above?
It must have been replaced due to structural problems with the wall.
These blocks were originally call Structural Terra Cotta Blocks.
AKA as Hollow Structural Tiles
Strucvtyural Clay Tiles
and Structural Clay Load-Bearing Wall Tiles.
Why would they go to the trouble of ecavating the exterior and not replace the whole lot of those terra cotta tiles as you call them?
Seems like a waste of money, if the complete assemble is not replaced as a whole.
Hopefully there is a water proofing system that was installed.
The high moisture in the floor system and the water at the sump could be indication of hydrostatic pressures from the exterior if the perimeter underdrains were not properly installed.
If it is that there is still a moisture problem after those remedial repairs to the exterior, something was not done right.
Taking a moisture reading on concrete floors with a moisture tester of the one you used might prove inaccurate.
The relative humidity readings of a concrete floor acceptable to flooring manufacturers is 75%.
No more than 3 lbs. of moisture per 1000 sq. ft…
Chances are there is an improper vapor barrier under the floor anyways, just contributing to the problem.
The sump pumps have to be replaced so they are functioning.
I would defer this whole thing to professionals that deal with this type of issues with moisture problems.
To many variables in the circumstances of the information you have provided. I would walk away from something like this and defer it to other experts in this type of scenario.
