" Well work is already underway and right now let's talk with Jesse from the contracting company and Randy is here from the building department. How come you use this very elaborate rig. Pouring all this time. Fun makes it much easier for us to Obama reach out to long distances to get them our backside this slab that's a lot harder to get concrete trucks up close and a slab minutes -- so it is it is more cost effectiveness. OK now before we look at it in depth over here let's talk about the conditions here. Is Randy we're right on the edge of this nice canal and this is all manmade real estate from maybe what forty years ago yes. It's up -- dredged up and used for -- and what's it like building on this material. By the material itself is mostly sand tomorrow and it's it's been up here long enough to drain equipment. OK so you can you can put a house here obviously you don't have to worry about it shifting to what happens -- this kind of soil condition when you have a hurricane. Well what we have here is not -- situation for flooding river marine. River into the hills and valleys -- creates -- velocity type of like well it's different here we have slowly rising water from a storm surge so it's a surge would come on in -- date this site. And what happens to a house slab when when when you have an inundation like that a flood like that well it's a stylus glad you could suffer from -- flooding. Home yet but erosion of the footings underneath the slab so that the house itself can all of a sudden tilt. How -- wash away practically yes so there are different techniques now that involve not just slab pouring but building a stem wall. Yes what it does is it puts the footer down below. The surface where it needs to be with the slab itself is brought up on wall -- this allows the floodwaters to go around the home. Rather than getting under is subjected to a full hydrostatic pressure exactly so Jesse explain to us what we're looking at."
" Here all we do first is we coming here we scrape this lot out and we come in and we are brought in put a bill here build a -- that. And we estimate that voters which are eight by sixteen voters we call them footings in other parts of the country good. The this is basically on the entire perimeter into base for whatever -- next it's a base for the three course stem wall right it's once we pour the footings then we place a three course stem wall. On top of that. And at the time of the slab pour in these areas here where the down rods are. These areas and these cells are filled solid. And when we do get to the slab floor along with this number five continuous here creates the bond for the top of the this is Latin number five reinforcing rod. That is continuous along the entire perimeter. Yes and also in the footings there is two bars of number five and it. OK so then this is all almost all one. Continuous war."
" The blocks get filled in and then the slab gets poured in right around us. And right now we can see that they're just doing some top dressing over there and we've still got this area and that's the garage right that's the pool area OK so there's still waste ago."
