Bricklaying on wooden floor

[mandg]

Hello everyone, seeking some advice that the bricklayer couldn't answer.

We are going to build a foundation for the installation of a Husqvarna stove.

In our house, we have a bamboo parquet floor, directly under the parquet there is chipboard with underfloor heating coils (water).

When the foundation is to be built, what should be placed against the floor? Removing the floor is not an option as it is glued and involves a lot of work.

I'm considering placing a plate or minorit board underneath, or gypsum, what would you do or how should it be done?

Most instructions I find suggest cutting away the floor which is not possible or feasible.

what would you have done or how should one do it?

Removed the floor......

What will everything weigh?

What will everything weigh?

the stove weighs 120 kg then lightweight concrete foundation 100 kg so 220 kg.

the beams below are reinforced and if there is a wall underneath. the beams are also spaced cc 300

 

[Dan_Johansson]

The weight should not be a problem.

Is it water-based underfloor heating? I assume there won't be coils under the stove?

Try using regular underlay felt to make it watertight during the casting.

Hello. Yes, there will be coils underneath. Don't want to rip up the floor. The idea is for the mason to build with lightweight concrete blocks in an H shape, and then the stove will be placed in the H. It's not a huge thing, will be about 80 wide and 62 deep. I think the minorit would be best, but wanted an opinion if someone has done something similar. Wooden floors do move. The minority shouldn't move and is also single, which the chimney sweep is likely to appreciate.

If there are loops underneath, you must distribute the load... I understand why the mason was hesitant, I don't think it's comme il faut to build on top of loops for underfloor water heating...

220kg can't be a problem due to the underfloor heating since it is grooved chipboard and not polystyrene?

 

[mandg]

220kg shouldn't be a problem due to the underfloor heating since it's routed chipboard and not polystyrene?

yes it is routed, the pipes are indeed beneath the surface of the chipboard.
