  @Traveler004 Lucky you! I have poured on the light side due to human error and the aircrete collapsed.... There are allot of variables present when pouring, even weather and barometric pressure affects the crete!

  While we haven't pumped vertically, we've successfully pumped horizontally by making our aircrete mixing container air-tight, then pressurizing the top with an air compressor so that the mix would flow through a hose attached at the bottom. Doing so seemed to have little effect on the foam, which set fine under the concrete slab we filled beneath.

  @bvad8486 that was a problem I first ran into when I was building my own foam generator, and running a separate air and foam solution line fixed the back feed problem for me.

  California Air Tools suggestions are good, a 1750rpm motor spinning around 700-800rpm pump will always be more quiet then those typical "5hp" big box store compressors. Champion is a great choice, but Emax Compressors have been impressing me lately. Check them out- Silent Series, made in USA, lots of nice features: Emax Silent 5hp 1ph 80 gallon - ESP05V080I1 Read more about air compressors in this review!

Make sure you can get free shipping from where ever you order from. https://www.walmart.com/ip/California-Air-Tools-CAT-2010A-1-0HP-2-Gallon-Ultra-Quiet-Aluminum-Tank-Air-Compressor/120856620?wmlspartner=wlpa&selectedSellerId=0&adid=22222222227043233667&wl0=&wl1=g&wl2=c&wl3=107559836597&wl4=pla-299761203677&wl5=1022762&wl6=&wl7=&wl8=&wl9=pla&wl10=8175035&wl11=online&wl12=120856620&wl13=&veh=sem&gclid=Cj0KCQiAnY_jBRDdARIsAIEqpJ00Uh3A-nAgjTys3kizNl_dv3zh2Yvo69EfsSf7WoBODTo9c_JAfwUaAvQsEALw_wcB This is a short video I did on my air compressor setup.

  I don't understand HOW your mixer works, but the blocks you made do look amazing. Do all your blocks look so good as that photo?

  I tried it out at the recent workshop. Unfortunately the bottom of the injector was a little too low and it was banging on the top of mixer blades. We were pressed for time and so we continued to use it like that until the constant banging finally broke it. It's important to get the bottom of the injector close as possible to the blades, but if it touches that's definitely too close. The other problem I had was getting the dang chuck tight enough. The mixer paddle fell out a few times while mixing and the key just didn't seem to fit right, even though I'm pretty sure it was the original key. Overall I think this setup could be very practical and could be an excellent solution if done properly.

  My insider source tells me that this is an active work in progress. It is a high priority project actively being pursued.

  Just came across this video and decided to put in a plug for California AirTools (they are not sponsoring this in any way). It was fairly boring until I got to the end, at which point I was quite impressed with the demonstrated differences between their compressors and the normal type. https://www.californiaairtools.com/how-to-videos/pump-motor-features-wear-parts/

  Combining two smaller air compressors may be a cost effective technique, as suggested in this video: Youtube Video

  That's the approach I was settling on--pouring through the crawlspace vents. I too considered maybe working on a raise platform to gravity-boost the pressure. FWIW, the contractor I used lined the lower few inches of the foundation down over the footer lip with "drain matting". If moisture condensed and ran down the inner foundation wall it would have a small space to continue seeping downward. I suppose a major plumbing leak also would be at least mitigated by this small gap. The matting was anchored directly into the foundation using a hammer drill and manually hammered concrete anchors. I think this product is also referred to as "dimple matting" or "wall drainage". They poured the concrete directly onto 6mil taped plastic right up to the drain mat. Plan on your house being more humid for the first couple days as the concrete cures. Since they did mine in one shot we awoke the next morning to tropical humidity and rivulets running down all the windows (it was Dec). I closed up my vents a few weeks after the concrete was poured. I plan to finish encapsulating by lining the foundation walls with sheet insulation. Best of luck, let us know how it turns out.

  @servi I'm also living in Cebu and looking into building domes for Siargao. Curious to know if you already started building a dome? Trying to gather people in Cebu who are interested in building Aircrete domes so we can join forces and maybe see if someone can give a workshop. I have a good location for this. Hope to connect.
