What you're viewing is a residential home in mesa Arizona my name is James Belville i'm the owner of concrete repairman llc here phoenix Arizona the concern and we're going to get to that when we get inside is why is the interior floor heaving upward and causing all of these cracks even a broken window windows coming out of square well here in Arizona hardly ever rains in Arizona right my neighbors don't have any rain gutters why should i have rain gutters well go find one of your neighbors that has a rain gutter go knock on their door and ask them why do you have rain gutters they'll tell you all about their interior floor heave cracks and how this occurs uh over the years and these foundations are the most Shallowest foundations in the united states they're 24 inches from the top of the interior floor elevation to the soil that's holding them up so when it rains and if you calculate length times width times depth of all of this rough rainfall let's just say it rained an inch over a period of 24 hours and you capture all of that rainfall and you place it near the shallowest foundations in the united states and you build a dam around it to even hold even more in here's what's going to happen this horizontal crack here is the stem wall foundation it's the top and the block sits on top of it you should never use patch material to cross a construction joint and so what happens is the foundation is moving down and separating from the block the interior walls are supporting the roof trusses but the foundation wall is moving down causing this separation along here then it starts to stair step stair stepping is a sign of settlement also a sinus settlement is the horizontal separation of the foundation Wall and another sign are vertical breaks in the foundation all of these are facts then you can go a little bit more and if we just look at how much this soil has shrunk and is pulling away from the foundation i can almost drop my knife in there so when you fill this damn like structure up more goes down deeper then the damage starts to increase faster in a shorter period of time cracks in soil doesn't mean oh my god your home was built on expansive soils your home was built on farmland or number three your home was the last one built in the neighborhood and that's where they put all the trash those are a lot of the well the top three things i hear all the time people say so what i'm here to do is to show you what i'm looking at and diagnosing foundation problems correctly based on facts not hearsay not being taught in a classroom setting by a professor that says pupils here's expansive clay soil we're going to submerge it in soil over the weekend we're going to come back Monday and boy it's as big as a basketball and then you let it dry out for a week and then it shrinks and cracks all over the place so when somebody other than me or or any other foundation contractors or specialists that sort of thing when they see this more than likely is oh my god you know expansive soil yeah and then if you have floor cracks you must have a bunch of water underneath your floor causing that expansive soil to heave your floors up it's not the case at all don't believe in that even though expansive soil is real over here in this corner then we also have the neighbor roof rainfall coming down and this soil is sloping towards the home and then whatever comes over here is also being dumped in here and the roof rainfall and atmospheric rain stair stepping occurs because that's going down vertical breaks happen because the foundation can no longer support itself because the soil is wet and can no longer support the vertical pressures being applied down to it by gravity it's like a 10-pound bowling ball on top of mud there's another vertical another vertical another vertical another vertical that's what these look like another one this one just so happens to come right up and start stair stepping and then another one had to break again to relieve even more pressure so as time goes on this really starts going quickly it's not because of expansive soil it's because you got a bunch of water here saturating the soil is holding it up going inside well before i go inside we have the stair stepping over here stair stepping over here and then in the middle of the house is basically being split right down the middle so this crack is a fact stair-stepping is a fact soil is shrinking is a fact pulling away adding more moisture to it the top of the foundation wall is separating not likely caused by expansive clay soils Arizona.
