While the inside person is doing the second  pass, someone on the outside should very carefully fill in around the water tube with a bit of cement if it has not already been done!  You want the tube to be well set in the cement.  This is the only place where we have had problems with leaks in the pass.  It is usually caused by someone bumping into the pipe nipple before it has a chance to dry!

The floor
Once the second pass is done, you will need to mix cement for a floor.  Use 2 botes de grava (gravel), the remaining cement, and the saved mixed cement (1/2 bote). 

Mix it all together then add a little water. Too much water in your floor can be dangerous to your inside walls. It will cause the walls to absorb water and can cause sections to fall off the walls. The floor mix should be very dry!

Hand in ALL the floor mix, half bucket at a time. Spread out the dry mix evenly (stamp down with your feet if you need to). 

It will be 2-3 inches thick.   When the floor is nearly finished, carefully place the ladder in the tank.

With someone heavier in weight standing on the ladder outside, the inside person can stand on (hang off) the ladder for finishing the floor.

Once done, climb out and remove the ladder.
