Time to pour concrete for the foundations of timber piles…
It’s been raining since we mounted formatubes and some of them became soft, but we took the risk of pouring concrete into them as we don’t have enough formatubes left to replace all of them and everytime we take them out the soil falls into the holes so the longer we wait the worse it is.
And again we had to pump out the water from holes and the pump overheated in the meantime so it was a lot of pressure to get it done before the pump and concrete arrived.
Here we go…
For most of the time we were too busy to take pictures. I was keeping the tubes as some of them were so short that under concrete pressure they just jumped out from the holes and Cosmin was vibrating the concrete. This time the vibrator we hired was much stronger (petrol vibrator rather than electric one we had previously) which also didn’t help with stability of formatubes. Also the supports for posts we made were not strong enough…. so some disasters happened….
As you can see they are clearly not aligned…. well another lesson from ‘expectations vs reality’ series.
We used wash out from the pump to strengthen our driveway, hope it helps for a while.
We almost succeeded to secure all openings from rain by covering them with the foil….. the front one, which is facing south was impossible to cover as wind was immediately taking out whatever fixings we tried to fix it with…. so in front we just secured the floor and it will have to suffice for now.
Back opening…
… and front opening…









I liked that you mentioned that in the rain formatubes can become soft. I’ve been planning on using some formatubes in the construction of my house and wasn’t sure if they needed to be protected. I’ll have to make sure I’m keeping the formatubes dry so they don’t lose their rigidity.
Hi Thomas,
I’m happy the information was useful. Formatubes are great but they are definitely not weatherproof. Also fixing them was quite challenging for such novice builders like us. Hope your project goes well and you find better way to keep them in place.
