Digging out a new floor
Old floors often only consist of a tiled floor on sand, so without a floor plate underneath. You can easily dig out this floor and replace it with a new and insulated floor.
Because full soil partly insulates, you need less floor insulation.
You get a completely new floor, similar to new construction.
You can provide underfloor heating without any problems.
Do you have a terraced house and do you renew the sewer system? Then you can connect a larger roof surface to a rainwater well and recover more rainwater for gardens, toilets, laundry ...
You can insulate the floor and thus already meet future renovation obligations.
Because you excavate the floor plate, the floor level does not have to be raised.
You can also renew the sewer system immediately.
LET OP VOOR
This has an impact on the stability of the structure.
Check whether the load-bearing walls are sufficiently deeply founded. Non-load-bearing walls may be removed.
These works are very drastic for the ground floor.
Ensure that the new floor insulation fits seamlessly with the adjacent floor and wall insulation. This way you prevent heat loss.
You may need to adjust the door and window openings.
All pipes and cables under the old floor (electricity, water, drainage ...) must be replaced.
DENK OOK AAN
Already take into account facades that you want to insulate later: provide a good solution for the construction joint between floor and facade.
Provide a suitable solution for doors or windows that you want to replace later, because they fit in best with floor insulation. It may be harder and more expensive if you only take this into account when you already have a new floor.
Take into account installations that you want to adjust later. Example: already provide waiting tubes for techniques (eg power lines) that you want to add later.
Do you integrate floor heating? Then check whether the old boiler is suitable for this.
