Modular Flush Screed Trunking

Flush Screed Trunking

This innovative and customisable system can be installed in new developments or in an existing installation. Below are some of our installation guidelines that needs to be considered when using this system.

Access (Existing Installations Only). Adequate space needs to be cut in the screed to allow access for trunking system and access for installation tools.

Solid Foundation. Screed trunking must be installed on a solid foundation and completely supported by a screed ribbon approved by an consultant or architect.

Lids and Service Boxes. The galvanised trunking lids and service boxes should be in position before the screed is poured to ensure the pressure of the screed does not distort the side walls of the trunking.

Levelling. Once the trunking is levelled and before coupling together, the screed ribbon/bedding should be packed under the trunking to remove the possibility of any voids which could create soft spots in the trunking system.

Finishing. Take care when pouring the screed. The screed should be compacted to provide a fixed support for the trunking system and its contents. Ensure the screed is smoothly finished to the trunking lid to prevent any lines showing on the final flooring finish.
