In my last video, we toured a factory that produces Insulated Concrete Forms or ICF blocks. Today we’re going to look at how an ICF wall is built with Fox Blocks as well as the pros and cons of this type of construction. NOT SPONSORED.
Chapters
0:00 Intro to Fox Blocks
1:02 Types of blocks
2:10 So how do you build ICF walls?
4:00 Advantages of ICF
6:04 6-in-1 assembly
8:22 Disadvantages of ICF
10:30 Summary
All Fox Blocks are made of molded polypropylene plastic ties which secures two pieces of 2 ⅝” thick Expanded Polystyrene foam pieces. The distance between them can vary from 4” to 12”. The blocks have teeth so they interlock on the next block, like Legos. The blocks should be staggered in a running bond method to avoid continuous seams. Horizontal rebar sits inside the ties to strengthen the wall assembly. Concrete is poured inside this sandwich and vibrated to eliminate air pockets, pack the aggregate, increase the density and strength of the wall.
After excavating the site, the concrete footing is poured on the perimeter walls with rebar sticking out of them. Next, the corner blocks are placed to define the edges. Straight blocks are then stacked in a running bond, staggered layout towards the center of each wall. Rebar or reinforcing steel bars, snap into the polypropylene ties of every single ICF block. The concrete in ICF walls must have a slump of 5” to 6” which is higher than a concrete mix for a floor which may be at 3”. The aggregate in the concrete must be between ⅜” to ¾”.
Advantages: Strength of the wall. They will withstand hurricanes and tornadoes, floods and they are fire-resistant. Air-tightness provided you use good quality doors, windows and a roof. The continuous interior and exterior insulation prevents mixing of cold and warm air, thus reducing condensation and mold. They have 1 to 1.5 ACH. They have a HERS rating of 30-50. Low sound transmission, STC rating of 50. Good R value. Great DIY wall assembly. Fox Blocks uses full-height ties and they have an extensive BIM library.
Fox Blocks markets their wall as a 6 in 1 assembly. The EPS foam acts as a natural vapor barrier, and provides continuous double layer insulation. The solid concrete core acts as an air barrier. The polypropylene ties have inbuilt rebar support and also act as fastening or furring strips for any finish. Their reversible interlocking design saves construction time and reduces waste.
Disadvantages: It is more expensive than wood construction in the States. They are not as good in cold climates. Waterproofing is expensive. Running electrical and water lines through the house, and even installing electrical boxes in your walls requires you to melt and cut out the EPS foam or even the ties. Any connections to the outside have to run through PVC sleeves which are placed before the concrete is poured. ICF homes can have humidity issues if it isn’t properly ventilated. The walls also occupy a lot of space. Concrete has a massive carbon footprint and is pretty destructive to the environment. But you also need to compare the short lifespan of a poorly built wood home to the 100+ year lifespan of an ICF home. Remodeling the exterior walls of your ICF home is nearly impossible. Less forgiving construction.
I think homeowners are slowly going to demand better-built homes because of all the information that is available on the internet. Right now, most people are just concerned with interior finishes like the type of granite used, shiplap walls, and hardwood flooring. They don’t realize that the bones of the building should take precedence over the stuff that you fill your home with. I can see ICF homes becoming more and more popular especially with custom builds.

I’m a ex general contractor. I truly love ICF walls. When you build a home with icf walls; make sure to install good dehumidifier, it can regulate the moisture in the house. Waterproofing? In northern part of state applied spray tar on the basement walls; it is fast and cheaper instead of applying expensive layers of sheathing. Thank you so much for your educational videos. It is good to hear from a architect views on the building. One of many things I see in usa 🇺🇸, not many people doesn’t know what is better way to build a house. The most production builders, they will skin the cat in the structural of the house and very poor quality carpenters and concrete. The most the walls not even level. They can’t even build a 50ft wall in a straight line. It is so sad. The production builders just do a modern lipstick on interior finishes and make looks so pretty. The house will start breaking down in 5 years. 2nd.. the recent freeze happened In Texas; most of the pipes are broken from attic. It is not climate control. The pipes were exposed on exterior temperature; little bit of temperature changes and stayed in 15 degrees for few days; many Houses got damaged. Do you think, the lessons ever learned? No, the production builders keep building same way. They are completely forgotten what is happened 2 weeks ago In Texas.

I do remodels and repairs and can second everything you've said. Floors, counters, ceilings- nothing is level or square. Pipes ran next to cracks in the sheathing provide super freezing wind tunnels every winter even in the somewhat milder area where I live. And then under the buildings...a long list of deficiencies and problems waiting just a couple years to happen. One huge housing tract built on old marsh land where they all have sump pumps pumping water into each other's homes and all the heating ducts under the house leaking and destroyed and causing mold throughout the homes. And they are on regular 8 inch pier blocks that are sinking. I bet the whole area has sunk significantly over the past couple years.

We narrowed it down to 2 homes at around the same price: One built in 1973 with 1500 square feet per floor, or one built in 1999 with 1200 square feet per floor. We went with the older home because of how cheap the construction on the newer home was.

Fast, quality, and "considerably" less expensive than traditional methods, materials all around. An absolutely astounding incredibly comfortable quiet home. There will have to be a revolution in materials and processes before I consider using a different process than ICF. AND SO EASY!

We built a 3 level, 12 classroom addition to a school using this method last year. Part of the reason it was chosen was cost. The budget was $2 million which we were able to stay on. Note: Much work, was done by volunteers such as the wired network, floor finishing, painting, and bathroom tiling. Interior walls were metal studs to allow "smurf" tubing for the AV equipment. The floors were Spancrete. The ICF part of the project went very smoothly, and it is a durable and safe building.

Living in Michigan we get some very cold days and with the thermal mass of the concrete walls you get a very consistent and comfortable living space throughout the whole house.

This was much easier to understand than the Pro-Builders I watched, I actually understand it now not just the pros and cons, and the focus on water management. Obviously both presentation styles are miles ahead of me walking past a construction site and looking over at the workers as they're there to work not teach strangers. Great points in the conclusion, I think combining this with Solar and air exchange devices will make these very safe and economical. If planning to expand the home it seems prudent to leave provisions for that in the initial build like a wall that isn't ICF or has an oversized door/window opening that can be adapted for another use. Yes all the stuff inside will be out of date in 20-30 years why not focus on the parts that can't be easily changed (the bones). I was also impressed with those three standing homes in that neighborhood, they looked completely unscathed, I didn't pixel peep to see how the windows and doors did, but the roofs looked fine in that quick glance too.

Great video. I basically agree with all your points about pros and cons. I would add one more pro that I only realized fully after I finished my 2000 sf home in 2013: The huge thermal mass. I live in central PA and I heat my house with a wood burner (gasifier) and radiant floor system. Even during the coldest days I only need to run my heater about every other day and just for 4- 8 hours depending on the weather. In the summer the house stays cool except for prolonged heatwaves (over 1-2 weeks). I don't have AC so a basically have no heating or cooling costs. The house is very tight though, and if we have a lot of people together (i.e. for Christmas) during the winter, we have to open the windows to get fresh air and cool down the room we are in. Thanks for the videos - I still have to watch more of them

Do you have a fresh air system installed in your place? If not, look into it. It'd cut down on the need to pop a window (which lets all the environmental dust, allergens, and other filth in from outside). And you could control the temperature the same way.

The shop in which I work has the foundation made of this stuff, but I've also seen full homes in Canada made of this stuff. R50 would definitely make the best Insulation, most homes are batted at r24 but icf has air sealing properties. Plus nowadays there are stronger storms so this option would be best for your permanent family home. Well done Belinda.

I have designed a number of ICF homes. I first used them about 25 years ago but they have more recently started to become more popular. The number one disadvantage in my mind is that if the rebar design is complex and the contractor makes a mistake, it is very difficult to fix. It is suited for simpler rebar designs. You tend to have more complex rebar designs in seismic areas and/or large windows and tall walls. We also use it in cold climates and that has not been too much of an issue. You can also use it just as a foundation wall. Where I am from, we usually use membranes etc on the foundation walls anyways so it is not an additional cost.

What if you use Helix micro rebar? That would eliminate conventional rebar complexity.

@yodaiam1000 3 жыл бұрын

@@rockys7726 I have never seen it used to replace reinforcing in a wall. I have seen it used in ground supported slab on grade and composite floor decking. These are items that do not cause a life safety concern when there is a failure of the reinforcing. I have heard of it used in walls but not as the main rebar. I would be very hesitant to use it as a replacement for rebar in walls. You also need a high slump concrete for tall 6" thick walls (for IFC this is more economical than 8" walls) and I don't know if that is feasible with the steel fibres. There is also nothing in the codes (where I live) that would permit the replacement of rebar with steel fibres. I once had a conversation with an architect who was involved with the renovation of a parkade where steel fibres were used. He swore that he would never use the product for any future projects. When ever they needed to cut the concrete there were steel slivers everywhere. They were getting all kinds of claims for punctured car tires. I would also be concerned with the flow of concrete around areas of high congestion of rebar. The review of dosing and mixing is not practical for most engineers if there is a life safety concern. That is not to say that at some future point this can't be addressed in some manner. I am also sure that the product has it place and uses.

@PhotonHerald 3 жыл бұрын

@@yodaiam1000 For non-seismic areas you can get away with replacing some of the rebar in the structure with Helix. In a seismic area, I'd use Helix in addition to the regular rebar schedule. This adds to the ductility of the concrete throughout the whole wall structure, rather than just at the points where the rebar exists.

@yodaiam1000 3 жыл бұрын

@@PhotonHerald Please reference the codes and research papers and I will take a look into it. If I have another product available to me that helps reduce construction complexity and costs, that would be of interest. I don't doubt you will gain ductility. How much ductility and the significance of the increase in ductility and capacity is what is important. We normally use a ductility and over-strength factor of 1.5 and 1.3 respectively (I am not from the US and we use slightly different values) for most concrete or steel houses. If we use higher factors we also have to review the relative increase in shear strength versus the bending strength if you want the bending strength to remain the weak link. Slump is also an important factor for these cases. It looks like you are from the US. Are you registered as either a P.E. or an S.E.?

Dear Belinda, Thank you for such a high quality content. I am also big fan of ICF homes. I have purchased a small lot in Southwest Florida (Naples area) and my plan is to model and build my home with an Owner Builder affidavit (I am looking at Vertical ICF). I am also looking at an ICF roof, using LiteDeck Steel Rib System, but that is even more challenging undertaking. One area of concern is termites, because they known to bore through foam insulation in search of wood. There are very few ICF homes built in Southwest Florida and what I was told, it is due to huge CMU construction industry. In fight with termites, the best practice is to use CMU blocks where ground contact is necessary and install ICF above the ground. There is also termites treated foam, but from it, derive numerous health risk speculations. Being in engineering myself, I love the idea of thorough CAD modelling, reviewing the design with family and subsequent BOM generation. Thank you so much and may God bless you!

I wanted to get into architecture when I was in high school, the idea of making a home and living in it was fascinating to me and learning that it is somewhat a well paid job it hyped me more. However, there wasn't enough hype in me to dedicate myself to get into this field since I grew rather really depressed and people pressured me to do better with my grades. So I just didn't go to college at all after high school. Stumbling upon your videos remind me of how much I used to secretly love drawing homes especially illustrating my ideal homes on notebooks.

Steel wall and truss systems allows longer unsupported walls for first and second floors. The only drawback is attaching required metal cutting screws in old block but with new plastic ribs allows attachment of drywall screws.

You addressed moisture issues with concrete being absorbent particularly at the foundation level and that some builders like to wrap the house with a Plastic membrane that has a tar like substrate. This I would suspect is quite combustible if Exposed to the high heat wild fires such as seen I California Spain and Canada. There is waterproof concrete used in bridge abutments as well as superstrong concrete and concrete with Fiberglas fibers. It seem logical one could put ingredients into the concrete for pouring the walls that would make it waterproof, just another cost.

The ICF blocks are going in the right direction but the cost is a big drawback along with the cons you pointed out. Thanks Belinda for another great educational video for us dumb architects...hehe

Would be fascinated to see a similar dive into the pros and cons of rammed earth construction, either the traditional or compressed earth blocks. I know there's a few places in Texas that specialise but it's hard to trust someone that's trying to sell you their wonder material to be objective about downsides.

Well done. I think you hit the nail on the head when you touched upon the fact that Styrofoam and concrete are not the best for the environment, but balanced against a well built, well drained home that could last over 100 years, it is certainly a good use for these materials.

Plus there are ways to cut down on the "green load" of both foam and concrete. And, with proper formulation, you can come close to making concrete a CO2 sink, rather than a source. Also, ammortized over the life of a building that could be around several hundred years, the "green load" dwindles into insignificance. Partly because of the lower HVAC bills/use, and because even the remaining load can be offset with various forms of renewable energy.

I read that ICF is cheaper than pour in place because you don’t need to build the form work. You also don’t need to attach insulation to the concrete as it’s already done.

Good job of explaining the benefits. This method of construction has improved since it's inception about 30 yrs ago. It's still a concrete structure with a convenient and beneficial forming system. Works great when done correctly as you stated. Can you give your opinions of AAC construction?

@stevepailet8258 3 жыл бұрын

properly installed some very good reasons for doing ICF. Sound resistance, thermal resistance, air and moisture resistive barrier, bugs and other vermin might eat the foam but not the concrete. So many good things. The bad is that there are not lots of builders using it. The cost per Sq Ft is very high in comparison to other means. If one want to do remodeling it is $$$ prohibitive. One really has to plan out where penetrations need to go: pipes for plumbing electrical and mechanical. Especially mechanical one tube per penetration so that there is never a problem doing air and moisture sealing. Really raising the ICF is dead simple. Can be done with a crew of high school kids. Even doing the zonts for truing the walls.

@PhotonHerald 3 жыл бұрын

A lot of these downsides are things that can be solved with a little initial skull work and communication with your architect. Then with good communication with your GC and subsidiary contractors. Also, some contractors sell ICFs impregnated with things that make them termite resistant. Additionally, there are some finish details and types of coatings and membranes that render the ICF protected against such things.

Should anyone attempt a DIY project with ICF, a good idea would be to find someone with past experience to help. The issues with plumb walls and blowouts can make a serious mess of things even with four foot lifts. So true about the beer guzzling. Hiring electrical and plumbing contractors can be problematic if they haven't done these before. The job requires them to split their job to do the ICF portion first, then come back for the rest. I found it critical to have the doors and windows on site before the build to have the dimensions on hand rather than trusting a blueprint. Invest in a good foam applicator. Blowout protection. I tried a white glue modified stucco finish directly on to exterior foam with no lathe. It has been 25 years now with no issues. Would I do it again? Hell no! Not then and not now. Thanks for the video Belinda.👍

1. If you can't plumb a wall you shouldn't be building any wall of any type. 2. Blowouts never happen with quality blocks that have been properly installed. 3. Our electrical and plumbing contractors give a discount for working with ICF walls because it is so much easier than working in stick walls. 4. If you can't trust your blue prints then you have already made a major mistake.

@wearemilesfromnowhere4630 3 жыл бұрын

@@tiberionblock1047 @Tiberion Block 1. Agreed! 2. The blocks are not the issue with blowouts. The issues I've observed have been with the placement and sealing of electrical boxes and other fixtures. 3. Once the plumbing and electrical contractors understand the installation, they do like it. I go back to my comment mentioning trying to get quotes from contractors that have not do so before. 4. Agreed! It is just a straight forward fact that once the walls are set, the "mistakes" have fewer options to rectify the issue. 5. I am sure since 25 years has passed, the quality and overall fitment of the blocks have improved tremendously. Peace

Great video, Belinda.! One big challenge in constructing an ICF building are common joints in the walls. Unless the walls are the perfect lengths, a common joint is needed to keep the TIE spacing the same throughout the wall. This joint creates a weak point in the forms that must be properly addressed to prevent a blowout.

@joshualruby 3 жыл бұрын

This is something I am working to remedy in my builds. I am an ICF expert and have always just dealt with seaming walls of particular lengths. I have now grown to the point I simply tell my clients that I will make the dimensions move a few inches or even a couple feet to save them a lot of money and my headaches by making everything for my blocks with no seams needed. It’s gone well and I hope to only have clients that let me do it from now on. Seams are for the birds. This does come down to her comment that you have to be more conscientious of the whole project when designing and account for planning a lot more than in standard construction. I have to work with the designers and have them tweak things and match the brand of ICF we will use (as I use 4 different brands), but it’s worth it on prep and pour for sure!

@zmanmd1641 3 жыл бұрын

@@joshualruby It would help greatly if the various block vendors created a list of lengths where no common seams are required to build a wall. Then those lengths could be incorporated in designs, for example that instead of designing a 40 foot long wall, you build a 40 foot 3 inch wall or 38 foot 6 inch wall to eliminate the common seam.
