@ChrisinKentucky I wonder how that happened? If every thing is in proper working order there should be very little pressure in any pvc pipe areas... Is it possible that you had a blockage somewhere?

@atravis4 make the blocks what ever size you find easy to work with.. I made mine 14.5”x 15.5”. The only reason mine are that size is because at my thickness 12 blocks that size come out perfectly from one batch of aircrete.

I have been using mortar and stucco for mine.. super strong and easy to work with :)

@algares looks great :) I’m sure your project will turn out amazing :)

@MADE Nice! Great info there! I’m sure you will be taken care of :) I wonder more now than ever what the diy plans called for pump wise? Knowing that the pump can not be bought thru anyone but domegaia I’m curious if they list a substitute pump in the material list?

@MADE I would contact aquatec directly..

I would hope they would warranty the pump. Domegaia would only be an intermediary in that process if they were involved. At the very least they may point you in the direction of a reseller that stocks the correct pump ;)

@MADE I think the rapid set is a great idea! Really looking forward to seeing how that works for you!

I would be a little sceptical of a 70psi pump though... It’s going to change your air pressure also.. Think about the pressure adjustment as a differential between air and water pressure. If you lower the water pressure 20psi, you must also lower your air pressure to match. Not much foaming action happening at 40psi. I curious where they recommend you buy this pump in the diy instructions? I looked at the aquatec site for quite a while and could not locate the part number of the original pump.. the kicker being the “h” pressure code.. none of the 5800 series go beyond “f” (70 psi). You might try Inquiring with aquatec directly?

Oh! And as far as what I do with the test foam.. toss it out, wash the car or something.. foam that’s not injected directly into the slurry will not ever be as good.

@MADE not sure what the sand/topping mix is.. it’s usually used to resurface worn or damaged concrete. It just happens to be inexpensive in Hawaii so I figured I would try it lol. $19 a bag for Portland here!
The result was very brittle and flaky.. mostly just crumbled. It was strange because the surface set very fast and hard.. all the sand settled after pouring and fell apart days later :(

Yeah that’s not right at all... any time after the 2nd day it should be pretty difficult to stick you finger in a block... the way I check my foam expansion ratio is by just checking the amount of water I have left after a batch, but that’s more because I have it dialed in already. If I end up with 1 1/2-2” of water in my bucket I assume I’m still in the ball park for the next batch, if not I make a small adjustment for the next one ;)

Starting from Zero.. fill your foam generator bucket 1/2 way, make a mark.. then add 1 gallon of water and make a new mark.. prep 2 empty 5 gallon buckets for foam filling.. after filling the 2 five gallon buckets with foam see where your foaming agent bucket is in relation to the starting mark.. my guess is that your air pressure is too low and you will be using over one gallon of solution to fill these buckets..

There is certainly a point where the water content is too high and it gives an indication that your mix is correct by weight.. This is why I moved to the expansion method. There is only one pressure that makes a 10:1 expansion :)
