The old house was sold in 2018 and we traveled for 20 months and now own a new house with new worries. Two weeks before we got the keys, we were informed that the upstairs toilet was leaking water all the way down to the basement. Just had to tear out, dry up, and build a new bathroom.
I intend to take up the old wooden floor to widen the toilet, and to run new pipes and pour self-leveling compound for underfloor heating.
Now that I have removed the toilet and sink and started sawing up the wooden floor, I realize there are no floor joists? Instead, I encounter cassettes or pockets with sawdust.
My question is; what is the framework in such a house? How is it constructed? and where do I find joists?
The house is from 1960 and a product brochure of the house says it is an Elementhus, from Mockfjärd with cross-laminated timber in the floors. Or, they are called "floor elements".
Can anyone help me make sense of this, I don't want to break up more of the floor until I know I have something to stand on again, but I should have found a joist with CC60 I think. But not?
In the attached picture, it is the WC space where I am lifting the floor, but I have also torn out all the closets to be able to widen the space.
Thanks in advance!
Hello,
Do not tear up any more floor!
What you think is a wooden floor is actually the upper part of the elements consisting of 20mm plywood, masonite boards on edge, and then 20mm plywood again. The cassettes are filled with wood shavings. There are no joists; instead, the cassettes form the floor framework themselves.
If you do a search on the forum, you'll find a lot of information.
