Installation of french drain/interior weeping tile system

in Toronto eh…and how much money did this cost?

He says, they’re parging the interior brick basement walls because he says it was deteriorating.
–Parging the inside walls will not stop further deterioration nor water that is entering through exterior cracks, deteriorated-parging etc

2:15 they are going to place Delta membrane on/against the inside foundation walls.
– The Delta membrane doesn’t really do anything, in fact it hides, conceals further water that will enter, it hides mold, efflorescence on walls, hides further deterioration of walls.

Here’s a brick foundation…
See the hole, deterioration on the outside?
So parging the inside does nothing to keep water from getting in anything like this on the exterior and won’t stop anything like this from further deterioration.

Brick walls, see the hole/gap around the exterior of gas line? Water gets in here as well.

Same things happen on block foundation walls. Sometimes, some interior blocks will deteriorate like this…

The exterior of block walls can also deteriorate, like this…
So parging or painting the inside of block, brick walls doesn’t stop further water or deterioration, no.

Installing interior basement systems and–or parging the inside basement wall won’t seal exterior cracks either, doesn’t stop those cracks from widening… like this

Installing interior basement systems or parging/painting the interior foundation wall doesn’t repair openings/gaps, open and widening mortar joints either, like this… go full screen if ya like
Do ya think mice, termites, ants etc can enter through any of these exterior cracks and open mortar joints?

If an HI is doing an inspection on a home that has anything like the above, what does the HI tell their client?
Do they tell them to install an interior system?
Do they recommend raising and sloping the grade? Mudjacking slabs?
100’ long downspout ext’s?
Parge or paint the inside basement walls and install delta membrane?

And, there are quite a few block or brick basement walls and crawlspace walls that were not parged when built or, were parged but the exterior parging cracks, deteriorates…like this/photo
And note the ‘other’ exterior gaps/openings that were, just UNDERNEATH concrete slabs/patio.

Here’s the same house, same corner… what it looked like on the inside of basement and quite a few basement-bathrooms are finished
the homeowner complained of a smell/stench in basement, hmm, wonder why

Parging the inside walls and-or installing an interior basement system and Delta membrane doesn’t repair/waterproof any of these exterior defects which is, where water is first entering many basements and crawlspaces.
These exterior cracks and other openings is also why many basements have x-amount of mold or efflorescence, discolored blocks and no interior system stops this either. They’ll try and hide it, conceal it, by placing/attaching some sort of paneling or membrane on the inside walls.

This house had concrete poured just underneath the back door sill, it was poured up–against the first course of unprotected bricks and unprotected mortar joints

Same area…


Quite a few of these inside system owners/salespeople etc actually tell homeowners (lie, deceive) there is no need for any exterior digging and that exterior waterproofing does not work etc. Really?
So how would anything other-than exterior waterproofing (what you see in these photos), stop further water from entering all these exterior openings? They won’t, they don’t.

Same house, what about anything like this… a separation where the foundation wall meets/kisses the footing

Basement system companies/network of 300 or whatever dealers, do not repair/waterproof any of the above photos of cracks, holes, deteriorated blocks/joints etc unless, they were to do what we do, what J McEwen does and a few others… exterior waterproofing done and backfilled correctly.
Neither does Everdry, B Dry, Basement Doc etc etc unless, they were to waterproof/repair any and all these defects on the outside.
They allow water, mice, insects whatever to continue to enter these exterior defects. If one doesn’t stop the water from where it’s actually entering then they will never stop/prevent mold, efflorescence etc.

And what do city, state, IBC codes/housing regulations state?
They state, ‘exterior of building must be weather-tight, without holes, cracks or deterioration that allows in water or vermin’
