A bath, tiled floor and new construction require a complete inventory.
Collect the loads
The structural engineer needs information about the current floor and planned additions. Vermeld de positie van een bad, eventuele screed, walls and other heavy parts. Use concrete product specifications when available.
Construction and engineering work together
In addition to load-bearing capacity, deformation and coordination with waterproofing and finishing are important. Leave a chosen floor system and any reinforcement on the existing one beam layer connect.
Describe the new structure layer by layer
A bathroom can place a different load on the floor than the previous room. Think of sheet layers, screed, tiles, sanitary facilities, walls and any underfloor heating. Some elements indicate a local load. Therefore, make an overview of products, thicknesses and positions. Ask the structural engineer what information is required about beams, spans and supports. A different floor finish may also be relevant stiffness, moisture and acoustics.
Coordinate services and openings before construction
Pipelines can end up where construction parts are in the way. Therefore, have the required openings and recesses drawn and coordinated in advance. Moving a drain can have consequences for the layout, floor height and supporting structure. Also discuss waterproof connections and plumbing support with the responsible party. This creates one executable structure instead of separate solutions per discipline.
Your preparation in four steps
- Beam sizes and span
- Construction and product weights
- Position of the bath and new walls
- Existing condition of the floor
Frequently asked questions on this topic
Are beam sizes sufficient to assess a wooden floor?
No. Span, distance between beams, material data, condition, supports and floor structure are also relevant. The assessment must also be in line with the intended use and any new openings or loads.
Why is deflection considered for a wooden floor?
In addition to strength, deformation and vibration behavior can be important for use and finishing. A heavier or stiffer floor structure can have other consequences than just extra weight. Discuss the entire structure with the designers involved.
