I'd heard about this system years ago on a program where the basement and house were built in a very cold area of the country (northern US or Canada, don't remember which). Gives the strength if concrete combined with insulation on exterior and interior walls. I was glad to actually see a video of construction using the system.

[@markjohnson6498]

Formadrain is the best product to create footings for ICF walls. They are light weight and easy to use. They are slotted on one side for superior drainage the entire length of the footing. They are easy to level and very home owner friendly. A first timer with some reasonable skills can create a perfect footing. I did it the first time by myself and it took one day to set it up including all the drain tile and installing some pvc cross drains to take the water either away from the slab or into an optional sump pump pit. I highly recommend a sump pump as well as either a gravity drain or a french drain depending on site layout. Formadrain is an excellent screed leveling system for your footing pour. It is also a great product for radon mitigation. Once you have a level footing I do not recommend pouring the slab until the ICF wall has been poured. This will allow anyone with a screw gun and mallet to plumb the forms. You can just use existing lumber from your building package to plumb your ICF's and then use them to build your structure. No waste. Simply screw boards to the plastic rebar clips in the forms and pound stakes into the dirt floor of basement for adjusting. If you pour slab first then you need a dedicated scaffold system that can only be used for ICF structures. ICF pours must be done in increments to insure against blowouts and voids in wall. Once your ICF's have been filled then all scaffold material can be reincorporated into structure and slab can be poured. ICF's are very homeowner friendly and make finished basements incredibly quiet and comfortable. They can lower heating costs by as much as 60%. This is ideal for areas where natural gas is not available. Propane costs can rise exponentially and fluctuate wildly with market conditions. ICF's can negate heating and cooling costs regardless of structure location and remove the chains of fossil fuel dependence. Remember you lose more heat through non insulated basement walls than through the roof.

Unless it has something to do with the seismic requirements, the horizontal rebar is on the wrong side of the wall. The rebar should be located on the tension side of the wall, not the compressive side.

[@infiniteadam7352]

Would there be any benifit to using fiberglass in the concrete in the walls in addition to the rebar?

[@Constructor-ly8in]

Infinite Adam, no, that would weaken the design of the concrete mix.

[@infiniteadam7352]

@@Constructor-ly8in do you know where I can learn more about this? I am surprised it wouldn't add strength but I would like to understand more about why it would have the adverse effect.

[@Constructor-ly8in]

Infinite Adam the concrete is a 3000 PSI mix, and the rebar design was done by my engineer to the seismic zone we are in, which is the same as Los Angeles (hence the large footings), so adding fiberglass to the mix as a strengthening agent isn’t necessary. I’m not sure where you would go for more info.

[@stephentaylor9366]

Sean, I know it’s a YEAR LATER. But, please reconsider using the icf for a full basement. There are so many hidden advantages that are not shown here, including time, $$, and the top floor’s construction. I’ve done about 200 of these in your part of the world and they can make your building life better, more profitable and easier. Hit me back if you want some more inside. Here’s a TIP: You can actually use the ICF walls to support your first floor joist hangers, and can place them before pouring the walls if you know what you’re doing. Then, you simply put plywood down on the joists, walk around on them and pour the basement walls. The home is squared, and plumbed by your floor system.

[@mrdiyguy123]

The drain tile placement starts a 12:36. To keep water away from the footing/wall interface and below the concrete pad, the top of the drain pipe should have been around the top of the footing. I know it is extra work to dig around the footings. My mistake was not being explicit enough with the excavator operator to dig the hole much bigger than the building size. I told him the building would be 36X36. That is the size hole he dug and that left me to make it bigger with my smaller tractor after he left. It was my first time building such a project but the excavator operator should have known better in my opinion or at least asked me enough questions about footing width and where the drain pipe was going. In my location we are required to have 16" wide footings for an 8" wall for residential construction. Most people pour 20" footings though. The footings in this video seem very large... I wonder if oversize footings are required in this location.

@@Constructor-ly8in - I think he means a water break between the top of the footer and the ICF wall. Instead of a water break, some people lay a poly sheet under the footer and wrap it after the pour, tying it in to the wall and slab membrane. If no water break, water can wick up from the base of the footer into the wall. But I’m not familiar with ICFs and maybe they don’t call for this?

The engineered plan called for an 18”x3’-8” wide footing, but we were building in an ancient river bed which created issues with finding a stable trench, cave-ins, etc, so the footing got a bit deeper than plan. We are in a seismic zone D there, also.

[@tompeterson9607]

How are the walls then rendered or clad?

[@Constructor-ly8in]

Tom Peterson interior walls can have drywall screwed directly to the foam via vertical plastic strips imbedded in the block. Wood or other nail-on finishes would need backing strips screwed to the block first if running vertically

[@patrickezuma7140]

So why did the inside of those forms need bracing but the outside didn't? Would the ties inside the form not keep the whole thing from bulging out and possibly failing? Also I don't know what kind of weight you plan on putting on those walls but those footing were massive. In the video they looked to be over 3 feet wide and almost as high. Are you guys in some kind of earthquake zone or something? Or maybe you just wanted to build something that will stand the test of time and never crack.....

[@Constructor-ly8in]

All good questions, with the ICFs you only have to brace the interior as the vertical bars on the inside screw into the blocks from top to bottom, and the blocks are all zip-tied together. The key is to get them perfectly plumb and not let them lean out at all. The footings were engineered at 3-8" wide and we are in an earthquake zone, but plus that, there are two floors and a roof on top of all that, and those basement walls are bearing all the way to the ridge..close to 40 feet from basement slab to ridge, shear walls on all four sides, etc. We are in a seismic zone D in Eagleville, which is the same zone as Los Angeles, and i'm a GC in Los Angeles.

Timothy Evagash, you’re absolutely right about the rocks!! However, in Los Angeles, where my actual company is, we still use concrete dobies and they do meet code/are approved here. Footing was designed by my LA engineer at 3-8 wide by 18” deep. It grew larger because of the rocks and sand ancient river bed we were in.

[@geoffrobinson7104]

Where are you located? I am a structural engineer in Colorado used to heavy snow and wind loads plus we have expansive clay through silt only soils. I would love to hear what your design criteria is. You have a wide footer, much wider to the inside of the wall, with lots of vertical rebar. You then add a heavily reinforced single layer of lots of reinforcement in the slab. I understand the pit in the floor but I am puzzled by wasting a yard of so to fill a hole that could be filled by dirt. ICF are a good choice if you are heating and finishing the basement. If you are not going to finish it, most building departments want it covered for fire protection anyway. I am puzzled also by no windows? One good trick is if your are finishing windows later, Install the bucks with treated wood plugs. At a later date you can add egress windows for usable space.

[@Constructor-ly8in]

Geoff Robinson this location is in the very northeastern corner of California 6 miles from Nevada and 40 miles south of Oregon. Because of the heavy geothermal activity here we are in seismic zone D, wind loads are 110 mph (we get hellacious winds here in the winter up to the max 110). Snow loads are 40 psf for a flat roof. The designed footing was 3'-8" wide, but the site is on an ancient river bed and the excavations got wider because river rock kept falling in on both sides. The vertical bars are the hooks for the walls, the near end was spaced at 8" because we exceeded the design max depth from grade of 6' by a foot. All others were at 16". The slab steel is #4's at 16" centers (my company is Los Angeles based as is the engineer, #4 bars are standard in slabs there, not sure what it is elsewhere). The choice of ICF's was partly for Insulation, and partly because the site is so remote there is an extreme lack of sub contractors; no masonry contractors within 150 miles, so I was able to build it myself with the ICF's. The walls will be finished with 5/8 type X drywall to meet fire codes. I will be building all the other stem walls with ICFs also to add to the overall energy efficiency of the building. No windows are required as the basement is not a living space, and the top of the basement walls are only 32" above grade.

[@Constructor-ly8in]
