Episode 18: After days of rain and delays, David’s crew works hard to prepare and set the LiteDeck ICF forms for the roof. There is a lot of preparation for a concrete rooftop deck, as John soon discovers. LiteDeck ICF panels easily span the 25 foot needed for the lake house. John joins the crew to explain the bracing system that extends from the roof forms all the way to the basement. Once cured, the LiteDeck roofing system will not require any bracing or columns, so open-living concept (even with a heavy concrete roof) can be achieved!
Our contractor goes over the LiteDeck forms in detail including how the spans are cut, shipped, and engineered to hold several tons of concrete for the rooftop deck. The rebar placement and bending is discussed and shown. John takes a final look around to be sure the roof is ready for concrete.

I was planning to build a PerfectBlock/EFBlock house with flat Litedeck second floor and roof before I found your channel. It has been priceless to watch your journey. Thank you so much for sharing this experience with us. We're going to be off grid, and our area has very soft water. We're planning to add a parapet wall, scuppers and rain catchment for our primary water supply here in NE TX were we get 47" of rain annually. Otherwise...pretty much the same as your setup. One twist I'm working on...I think I'm going to do do "bays" with the Litedeck running sideways and a center wall separating the living side and the bedroom side. I think I'll get more square footage for the money.

@LakeLotBuild 2 года назад

Sounds awesome!!! Make sure they get the slope right on the roof so that you get the correct drainage off the rooftop.

So do you need any support Columbus after it’s been poured and had the 30 day drying time or does all that floor to ceiling bracing come out?

@LakeLotBuild Год назад

All the bracing comes out. We have no columns in the house at all.

As a concrete of almost 50 yrs you couldn't pay me enough to be part of that pour. Scary as hell.

@elliottdiedrich3068 2 года назад

I know what you are talking about; I saw the concrete ceiling of a huge tank for a water treatment plant collapse in the middle of the pour. Things started shifting as they do when a lot of weight is added unevenly and eventually, a shoring post buckled causing a chain reaction with the others. What a mess that was! The contractor declared bankruptcy the next day.

What microphone were you using to record that video? It turned out really good. You can hear ambient noises plus here you really good?

@LakeLotBuild Год назад

It is a lapel mic with a really long cord plugged directly into the phone we use for filming. I was looking for the exact model on Amazon, but I can't find it. It was really just an inexpensive lapel mic.

@augggie 6 месяцев назад

Great videos, I will be doing ICF too in Bonne Terre . Everything your doing is perfect, except for one thing, why so far away from the lake? ❤

@LakeLotBuild 6 месяцев назад

We are as close as we could afford 🤣 That, and if you're close to the lake, you actually only get a very small viewing portion of the water. Like I know some people who are on the water but they're back in a cove and they might as well be living on a pond instead of a huge lake like table rock. Being up high on the mountain we get to see a huge swath of the lake and people always remark about how beautiful the view is when they come in the front door. We're happy 😁

@kirkshirley1319 3 года назад

Concrete cracks, so are you going to put a waterproofing membrane on the very top? How will you end a waterproof membrane? Extending the concrete over the outside edge of the ICF is a good idea but you don't seem to have a drip edge.

@LakeLotBuild 3 года назад

We have Xypex in the concrete which is a waterproofing additive. We will also use a multi-step roll on product with a walkable finish over the concrete. We will be filming that process soon.

@Krazie-Ivan 3 года назад

Ha! Knew the deck view would be worth doing :D EDIT: also curious what in/ft pitch you're going with for rain run-off, and if the engineer gave an indication of what snow load it's calculated to handle? (reason i suggested the deck was partially cause i had the idea for a Casita we've yet to build, but wanted to see it done somewhere 1st so we'd learn from it, lol... -thx!)

@LakeLotBuild 3 года назад

No worries about snow load. We never get more than a couple of inches here,but that said, you could park cars on this roof, so it can hold plenty. Our slope is somewhere between 1/8 and 1/4 inch per foot.

@uticatechclub923 Год назад

I am building an ICF house in Florida with similar ICF flat roof. The main roof is approximately 40x38 feet, 17.5 inch foam + 3.5 inch concrete. The ICF roof rep suggested to embed the channel into the concrete along the perimeter to serve as gutter. The engineering company suggested that the contractor slopes the concrete layer for water management. My fear is that with 3.5 inch concrete overall layer they will make it super thick in higher areas and skinny thin in lower areas and it will not be consistent. What I was thinking is to shave the top of ICF walls to make a slight slope and then laydown / shore the LiteDeck according to that slope. This way the concrete guys would just care to pour 3.5 inches of concrete throughout the entire roof span. Could you please elaborate on this?

@LakeLotBuild Год назад

Yes! Your plan is excellent. Slope the roof so you can have an even pour and ensure the proper slope.

Do you have any plans within your house design to construct a column-free cantilevered ROOM/DECK with the LiteDECK solution..??? 🤔 Thanks..!!! 👍💯👌

@LakeLotBuild 3 года назад

Hi Norman! We did the garage floor with LiteDeck and it is suspended and column free over our master bedroom. It is meant to hold two cars,so I would think you could creat a cantilevered room. That would be cool!

@robnowe5464 Год назад

Looking to do something similar. I have a question as to why you chose LiteDeck and not one of the other systems, since there are several ICF Deck Systems (Amvic, BuildDeck, Insul-Deck, EPS Deck, Fortruss, and LiteDeck) available?

@LakeLotBuild Год назад

LiteDeck was the only one suggested by our ICF contactor.

@ronraterman4092 Год назад

Would you use lite deck again? There are other ways of doing a suspended slab.

@LakeLotBuild Год назад

I think the answer is "maybe." We really like the fact that it is insulated so that we don't lose or gain heat through the garage floor. We researched pan and pour and just though the insulation factor of LiteDeck was better. There may be a better option out there though for other homes and situations.

@JP-kb4yi 3 года назад

I just came across your channel. Are you the future homeowner or the GC?

@LakeLotBuild 3 года назад

Both! We are acting GC and homeowners. The ICF crew is subcontracted but also does full custom build outs. We will have them get us dried in and then we will subcontract and/or do everything else ourselves.

Is there a way to do an icf addition and do foam over the existing structure? I've got asbestos siding in decent shape and would rather encapsulate than remove.

I'm not sure. An ICF builder in your area could at least look at what you have and give you their opinion. Good luck on your addition and thanks for watching!

@sergioarzola3596 2 года назад

Hello, What type of roof system did you used. What was your square feet/per dollar. We are getting ready to do a ICF build but I am still trying figure the roof system and cost. How did you run A/C ducking?? Thank you.

@LakeLotBuild 2 года назад

Hi! We used an elastomeric roll on product for the roof. We also used Xypex in the concrete to help wit waterproofing. We are still not entirely happy with our roof as the slope was not done right and we have ponding water. Be sure to do a good slope on the concrete for the roof. We put in our own HVAC system. Here is the video on that ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FqhquG0NEdw.html

@sergioarzola3596 2 года назад

Thank you for your reply, Yes, will be using an elastomeric paint finish and anything else recommended to make sure is is done right. Pitch will be 2”-3”/12”. I will look at your video for HVAC later today. Material and installation did you came out with $14.50 per square feet.

@sergioarzola3596 2 года назад

I was recommended litedeck srs system for flooring and roof.

@LakeLotBuild 2 года назад

Oh the LiteDeck was very expensive! The elastomeric product though was less than $10 per SQ ft.

@sergioarzola3596 2 года назад

Yes I notice that too. Going to have heave to look at other systems and come up with the total cost. Thank you.

@getin6 3 года назад

Can I get a cost breakdown from start to finish just starting my journey into ICF and I'm just wondering what the prices are from laying the foundation to laying out the forms for the actual house thanks

@LakeLotBuild 3 года назад

Thank you for watching! It is so difficult to tell you what you might encounter with your lot and build versus ours. We had a lot of excavation work first because we are built on a steep slope. We also have a concrete roof,which is uncommon and not typically bid in an ICF house. We also have two huge concrete decks going on the back of the house. Our ICF contractor is doing all of that work, so it is hard to break it down. What I can tell you is that the US Department of housing did a research study for HUD and found that a typical ICF home only adds 3 to 5% more over a typical build. Of course this is when lumber was much less than what it is today. We figure that we actually saved money building with ICF and current lumber prices. The cost of your ICF blocks will also vary based upon your builder. Our builder builds several ICF homes and so he's able to buy semi trucks full of block. If your builder is just doing your home, he or she would not be able to get the volume discount pricing that our builder is probably getting. I would definitely encourage you to reach out to Fox blocks or a local ICF builder and just ask them if they could offer am estimated cost per SQ. Foot. What I can tell you is that we wouldn't build with anything other than ICF at this point. It's a vastly superior product to a wood, in our opinion.

@getin6 3 года назад

@@LakeLotBuild so they did foundation as well or was that done separate from another contractor

@LakeLotBuild 3 года назад

We did the excavation separately but the ICF contractor did some of his own backfill and prep for the foundation. He poured the foundation in a monolithic pour. We have a video of that too if you want to see that process.
