Prefabricated wet room modules
Today it is common to use prefabricated wet room modules as an alternative to a in site-built bathroom in new building projects. It is then important to set the right requirements for the design and that the entire wet room module is tested and approved according to our Swedish rules.
Purpose
It is of course extremely important that the finished wet room module is waterproof and there is no leakage of water at penetrations, wall and floor angles, floor drain, fixings or linking. It is also important that the different materials are compatible with each other and do not cause corrosion or other damage.
RISE has extensive expertise and services in the prefabricated wet room area, some examples include:
- Watertight and load tests according to ETAG 022. Water spray of floors, walls, penetrations that is, everything where there is a risk of leakage. Load of pipe penetrations and suspension devices, all to mimic real use.
- Corrosion resistance and compatibility between different materials
- Moisture calculations of different design designs
- Damage investigations
We work with type approval of prefabricated wet room modules. Type approval is a national system for assessing and verifying the conformity of construction products with requirements in Swedish building regulations. This means that the construction product is assessed in the aspects expressly stated in the type-approval, by references to the Planning and Construction Act and sections of – The Swedish National Board of Housing, Building and Planning's Building Regulations.
A type-approval helps the developer to certify that the construction product meets the requirements of the Swedish building regulations. RISE publishes type approval and the associated document, usually the installation instructions.
The holder may refer to type approval to show that the product is tested and certified by a third party and complies with Swedish building regulations.
Method
A test method used for function testing of wet room modules is: EAD 030352-00-0503 combination of Annexes A and E (former ETAG 022).
Type approval of wet room modules takes place according to CR 136 Certification rule for type approval of prefabricated wet room modules.
Deliveries
Tests are presented in a test report. In the case of type-approval, a certificate is issued.
