Great video! So nice to see the camaraderie between builders, it shows how essential it is to build a knowledgeable network.

I'm blown away at that wall. I've google image searched many concrete board form walls and none have looked that good. That's real craftsmanship!

You have the best reaction to great craftsmanship and design. Its what keeps me hooked. You can really hear the passion in your voice. Others see Concrete and you see many hours of time spent fine tuning a system. Loving the videos!!

You need to have Brian on monthly. He is next level!! Thanks for sharing

I'd love to see the finished product here, or at least some more steps in-between. Looks like maybe 4 buildings? Curious to see where the 36' window is going. Love the form work. I have curved and undulating walls in my house. They weren't supposed to be, though :P

Once had to form up a curved ramp with a rigid insulation core and stub wall for a parkade entry. I used two layers of 3/8th ply for the forms, wrapped them around custom diameter plywood whalers and secured them with strongbacks and strategically positioned camlocks. It was hard to put together, as I worked alone under a foreman who no one else would work with. Still, it meant I got to design, build, and pour it on my own, so I got a lot of satisfaction from it.

Wow, that grain pattern in the concrete is gorgeous.

Amazing work done by true craftsmen. Hope you can visit again and see the finished product, its gonna be WOW!

I do some similar form work, but I use a torch and a wire brush to burn the surface of the wood highlight the grain. Also, I joint the edges of the boards and stack them with spacers protruding into the fill space so that the casting has recessed joint lines. Lots of impressive work on that site. Thanks for sharing it.

Very impressive. Smart idea to sandblast to bring out the grain.

Thank god we still have old school but at the same time super progressive builders like you & Brian. I am always awe struck at the things I learn from you, you are a true treasure Matt, much thanks!

Nice effect with the blasted boards. A thin protruding spline between the boards would give the finishing touch.

So many details! I'll probably watch this video many times

Brian is a true craftsman! Incredible attention to detail with his concrete work, very inspiring!

We do impressions on our form work also but we use rubber mats attached to the forms. We can create any style pattern in a cost effective way. All I see is a lot of wasted wood on these pours. But I am also in the super high end building business. So, I understand that some client want an over the top story to tell their friends behind the build while having dinner at the new place!! I am sure it will be stunning when it's done. Great work guys!

Amazing Matt, so grateful for you taking the time to make the video. I love the timber grain in the concrete wall and the piles are fantastic! Please thank Brian for me from Sydney Australia.

Another great video Matt, thanks for sharing! I love to see builders admiring other's work. You seem to have quite a network of humble but experienced contractors you keep in touch with and share with us.

Can you go back and do a video on the curved windows when they arrive? I'm more curious about the packing, shipping and installation than anything else.

Another great video. It's never a disappointment watching your stuff. I love learning about new techniques in construction and from energy conservation to curved concrete wall with a wood grain feature. Wow. The information you put out on your KZfaq vids is priceless. Keep up the great work.

You think they would have put a bead of silicon on the cracks between the boards to eliminate the protrusions on the final product instead of the normal crevice?

Concrete is such a fantastic material to build a home with.

I’ve custom built 8 of the 11 homes that I’ve owned over the last 23 yrs, but man-o-man, nothing of this level of customization and design.... envious of the location’s natural beauty and the level of quality craftsmanship.... must be in excess of $5MM if it is waterfront in the Austin burbs

This is over the edge between a traditional house and archtectual art. With care these art works can last, 3 or more lifetimes.

Obviously money is no object on Lake Austin. Great video.

Matt, we are building a 3 story waterfront house with attached boat dock, elevator, and lakeside pool on lake Lbj. Slab also has pilings in all beams. We are starting in 30-45 days. You should film the progress.

Priceless information again, thanks for the informative videos!

Hope you show the house when it's finished. Sounds like it's gonna be stunning.

Matt, I built an 11,700 sq ft. Commercial building with sand blasted white cypress on a tilt wall project. It was an epic building. Very similar look in Florida.

Our 1st home in South Porcupine, Canada had a poured basement where they used boards to make the forms, and the whole basement had that wood grain to though not as accentuated as that, our home was built in 1930... nice job.

This is a great video. Lots to learn. Thank you. Great to see the camaraderie between you two gentlemen. I’d love to know the difference between sandblasting and wire brushing Douglas fir. Those are the two techniques and this sandblasting technique is phenomenal. I wonder if similar results could be achieved with wire brushing on one of the big rotary sanders or similar.

Matt just throwing rocks down the dudes steel pile forms xD lol

That looks amazing. I would love to see the window install! Thank you, love to watch. It’s nice to see that there are talented trades out there.

Great video. The sand blasting of doug fir is clutch. The wood sucks up most of the moisture so the silicone is only to keep the dribble in control. I thought all piles... whether..auger, precast or steel pipe are interconnected with rebar tie beams. Some on grade and some in the air.. ??... Reject oil pipe works well b/c it arrives in small sections and is easier to house on site and handle. CHEERS

I want to see this when it's done!

I wish if you continue with following out the whole building process and show us extensive report of the final product. I am sure it'll be very nice design

Awesome video. That is the best concrete timber pattern I've seen.

The toughest job 🙏... Hats off Brian sir

Nice to see the house once completed...just can't imagine the labor costs just for one wall...

love that concrete wall. would love to see this finished.

Another great show Matt! You've got the best builder show / networking videos IMO. 😎

With a few million dollars, the sky is the limit. I am jealous. I came here looking for how to build a curved wall. I got more than I bargained for.

This is so beautiful! Thank you for filming it.

Great build. Wish you could have visited it when they installed the windows, that detail would be interesting. Also maybe do, if and when you get a chance to, a window installation in a both side visible concete wall like they have here. Thermal breaking details and such often differ....so any doable solution can be a good new idea.

Awesome work and great vid. Hope to see a follow up vid of this project in the future.

From a distance that wall looks like larch when it starts ageing. Amazing work.

Boy, that is some next level stuff right there!

And I'll see you next time ONNnn the BUILD SHOW.

Fascinating! Thanks for the informative video.

Awesome work here

revisit to this project.... nice 1 matt

Bad ass project

The lumber and labor for the form making is an order of magnitude higher in price than the concrete itself.

Amazing work

The texture of that wood id Epic. Not a super fan of that dad gray color tho. May be It would be worth trying some aditive that gives some sand like tone.

Wow fabulous…👍

I can understand why you dont make everything with concrete and bricks. You already have solid start. Hi from Europe.

Hi Matt any chance of doing an update on this project?

brombal is amazing stuff! Wonder if it has some olson kundig styles. I want to see a video of that next Matt

I met Tim Hill at his job on Watersedge Cove in that neighborhood last summer! I built the waterfall, if you know what I'm referencing.

Do you have a link to the windows he mentioned from Italy?

stabilizers, plasticizers... proper use of vibrators... silicone on boards... sound like some interesting building science Matt!

Hi Matt, very cool ! I'm curious what is the end product going to look like? Are they planning to leave the curved concrete wall unfinished, as poured, or stain and polish, maybe a clear coat? Something like you might see used for a countertop.... Also, it's kind of interesting to see so many comments about money. Yes, I'm fairly certain that this will be a high end house and very expensive per foot to build. It's important to remember that when someone creates new ideas, they are essentially blazing the trail for everyone else. With a little time , somebody, somewhere will see this and be inspired to create a far more efficient way to do this for half as much . So pushing the envelope, even if it's expensive is great for all of us. Thanks Again Matt for sharing 👍🏻💯

Yes!

That is the old school way of doing concrete walls. If you go to Lewes Delaware and stop by cape Henlopen, check out the world war 2 bunkers. You can see the wood pattern in the walls.

How is shrinkage cracking handled on longer runs of these architectural walls? I see they're not restrained at the ends, but even so, I'd be worried about it, especially at window bucks, but really anywhere the length is over 10' (that's what I was taught is max. w/o control. Is there a control joint detail? Are they cut in after pour?

Hey Matt! Love your content! I'm curious what your thoughts are on using shou sugi ban boards vs sand blasting to expose the wood grain? Would it be more cost effective and convenient to char and brush the boards on site vs the expense, setup, and precautions needed for sand blasting? Also, would shou sugi ban boards release better after casting the concrete? Would they be less porous than the sand blasted counterparts and, if so, would this have to be accommodated for in the concrete mix design?

Hello Matt, what does he use for a parting compound between the douglass fir and concrete?

seen the wood grain in concrete before... on old buildings.. from before they used plywood for the concrete forms..

I want to hear more about those windows!

Hey How about going back to that Waterproofing/French Drain house to show how it looks when landscapes and working?

6:42 He says Brombal, for those who want to search it.

How where the sandblasted board attached to the formwork screwed nailed.. or the fiberglass rods

Hey mate, amazing video. Those walls were amazing, just a small criticism, build sites are rough and we all know how hard it is to hold a camera steadily while walking on rough terrain, which make a the video really shaky and quite tiring to watch. If u were to get a gyro stabilized gimbal it would look heaps better.

Great video! If you have time can you visit this site later on so that we can see the progress made?

Very impressive. Great video as always, do you know what happens to all that wood ? Must be a total loss after the pour ?

What a look!

I saw you were having issues sand blasting on site. There’s a company called dustless blasting that uses crushed glass in a water vapor that might work for on site blasting. They are based out of Texas and have a network of contractors that can come out with a mobile unit. If you don’t know about them already. Lol

great video

what kind of wood is he using...it is just amazing and a beauty....

Idea: use modular formwork but for the wood shape use a Silicon rolled wooden pattern layer

The only "giveaway" on the finished wall is that the joints between the boards stick out rather than looking like a gap between the boards. Perhaps someone can figure out how to attach strips between the form boards to create the look.

wow go back id like to follow this build

+1. The Concrete wall detail having a substantial foam core width can't be beaten. The interior aspect becomes a heating/cooling flywheel extraordinaire. .. Radiant HVAC all the way ... "You can pay me now or pay me later. But you will pay me." .. Factor typical utility costs into the HVAC system performance.

Would this not be easier to 3d print? And cheaper? Sure you wouldn't get the timber grain relief.. but you could always stamp if you really wanted to.

Hey Matt! Always awesome.

Imagine using same technique but with rammed earth. That would look incredible

Love the texture on the sandblasted boards. The raised lines are a bit of a distraction to me though. Is there a way to lower the visual lines between boards? Would ripping the corners off or smoothing the gap with a bead of silicone work?

How did they fasten the boards to the strong backs? I saw one screw on the wall getting formed but didn't see any evidence on the finished wall.

Amazing!

Matt, if you are able and willing, will you please list the Italian window/glass manufacturer that Brian Long mentioned? I searched for it using Google, but had no luck. My Italian is worser than my English so that didn't help. Grazie.

@Matt Risinger Normally people make videos about how to prevent curved concrete walls.

Where I live your lucky to get a wall thats straight, level, and plumb and between planning and zoning and all of the homeowner associations pretty much every house built in the last 20 years looks the same as every other house, brick, gabled roof, asphalt shingles. I tried to build a custom home and was told by P&Z that they wouldn't give me a permit because it wouldn't "Fit In" with other homes in the area.....

Looks amazing! Are those the RJD fiberglass wall ties?

Do you have a list of some Austin area architects that you have frequently worked with?

I've seen that water bleed and the resulting weak sand pit. The cement bleeds out with the water. Silicone is a good idea.

Awesome!

Looks like the bottom of Mt. Bonnell .... uber exclusive neighborhood if so ....

Hi Matt, wouldn't it be easier and more cost & time efficient to use grain pattern plastic form liners?

What’s the tie spacing on your board forming?

Hey Matt, I bought a brand new built house about 4 months ago. It has a warranty on everything for the first year, and some other things for multiple years, from top to bottom. I've had an issue with rain water coming in through one of my bathroom vents, the one to vent out the bathroom not the ac vent, whenever heavy rains and wind come through. It only happens in one bathroom. I called the builder, he came by, took a look, and said it was due to the weather, but there was no problem with the roof. His explanation was the wind must have blown some flap open that he mentioned for the vent and rain got in but that it's something that should rarely happen, and he left. Storms came through again, and the same issue happened. Is there a way this can be fixed, and if so, is he just being lazy? It doesn't happen with light or moderate rain, just heavy rain with wind.
