Who Posted A While Back About Their Front Porch Slab Caving In?

Patrick

Who posted a while back about their front porch slab caving in? Can someone remind me, and let me know where the thread is? I have just run into the same crazy problem, looking for some ideas.

Yes, I went to look at a large project yesturday, and their front porch is about to turn into that ANY day now. The only problem is its actual basement under there, and that is where the oil tank is!

Waiting to get a mason out there to inspect. They wanna go with an all composite porch. Is it possible to frame over the hole with a slight outward slant, sheath it, put some roll roofing on it, and then build my porch over that on sleepers? its a 4'x20' space

They say anything is possible.
Doesn't sound like a good idea though,
at least not to me.
I'd rather solve the problem,
then worry about the cosmetics.
I understand that HO's would rather
spend the money on the pretty stuff
that they can see though.

NEo, Im not talking about a band aide, Im talking about busting out the slab, and comming up with an alternative to going back with concrete. Just trying to figure a way seal up the hole once the concrete is removed.

It is a 4" slab sitting on 1/2" plywood resting on a 2x4 nailed to the rim joist of the house! the plywood is deflected about 6"! and the slab is sunk about 4" in the middle.

looking for ideas that would not require the use of concrete since we are going back with a composite porch. Or do we need a concrete slab anyways?

Need to talk with the roofers
about the best membranes...
I'm not up on that.
Proper framing and treated plywood,
if it's flashed well, that ought to
work for you.

Sorry I mis-read before.
Just used to those deals.

haha thanks neo, I didint want my good guy image with you to be tainted. Its going to be a covered farmers porch so there really wont be a lot of water getting in there, mainly just for extreme downpours, and to keep insects and animals out. I have enough room so that the porch can be framed above the membrane and no sleepers will be needed.

I think on a span like that I would use B-decking. If I would have been building that, I would have had the masons create a lip on the poured concrete/block walls, and spanned it with decking. I would never just tie in with rebar like the picture in the other thread.

If its covered with a roof why not fir or mahogany T&G porch decking on sleepers over a plywood deck with Grace I&W? The reason I would put sleepers under it would be to allow it to dry out underneath.

The want azek/procell. Mason swears up and down that i need to put new concrete back anyways???? Cant understand why. I gotta talk to the inspector, I cant think of any code reason why there needs to be concrete there.

Could be an issue with the
fuel tank?
Could be that no part of the
foundation can be frame outside
the footprint of the house?

You can install a dry-deck system under it but it needs to be flashed correctly and insulation would have to be addressed. You could install the dry-deck system first and then frame down the cieling for insulation purposes.

Patrick

is dry deck 100% with out a doubt water proof? Do they have a guarantee?

of course not lol. I have been slammed since the home show. There just isn't enough time in the day. I just sat down tonight and put together "the list" of all the houses i have contracts for and started assigning the approx number of days for each project (under ideal conditions of course) , and realized i am booked for a LONG time.

So as far as this job goes, I just need to get someone in there to make it safe, seal it up, and make it look pretty eventually. this porch issue is tiny in comparison with the entire job scope.

While on the subject for an entirely different job, anyone have a rough idea of total cost for a set of precast steps? 4x5 platform and one step?

It has to be flashed correctly!!! I have to go fix a dry-deck system that some guy put in and didnt know what he was doing. Deck looks great but the dry-deck failed due to not flashing it right. Dry-deck is pretty much soffit that channels the water into a gutter so you will need a place for the downspout, all you need is a few inches to get a drop for the water and then you can run the gutter through the wall (or whatever is there) Or there is always pre-cast concrete panels. If you go with the dry-deck and you arent sure of the flashing, overflash or call a GOOD roofer. Good Luck

Patrick

Lol I like to think we're pretty good roofers.

You know what I mean though about the good roofer as compared to the guy that fed shingles and thinks he's the sh*t. Flashing is crucial on those systems but the products do work. they have no insulation value at all, that's why I said about the framed down cieling so you could insulate it since they want to keep the space available and it wont take alot of time/money to do it on your end. detail oriented job= money for you.

Patrick

Town said no concrete needed, bust it out and frame away. They suggested corrugated roofing and hanging the new porch over the foundation so that the exit point for penetrating water is hidden behind the skirting.
