KEY INSTALLATION POINTS

Prior to any screeding being installed we recommend the following actions are taken to ensure the screed conforms to regulations and is properly prepared.

  • Areas going to be screeded should be made watertight to prevent any type of leakage.
  • When a polythene slip membrane is installed over the insulation, this must be overlapped and sealed to prevent any loss of screed.
  • All pipes and cables should be securely fixed to prevent floatation and lifting during application of the screed, this can happen without the right precautions.
  • There must be a minimum cover to pipes or cables of 30mm. Where necessary, surface laitance should be removed prior to commissioning of under floor heating on site.
  • All screed moisture content must be a maximum of 0.5% and 1.0% respectively prior to application of subsequent impermeable and permeable floor coverings.

MAXIMUM BAY LENGTH:

The recommended maximum bay lengths for installations of Lafarge Gyvlon Screeds without the introduction of joints are as follows:

Floating on Insulation Nominal 30m ( max 40m )
Unbonded on Polythene/Visqueen Nominal 30m ( max 40m )
Bonded Nominal 30m ( max 40m )
Underfloor Heating Nominal 30m ( max 40m )

MOVEMENT JOINTS:

Similar to all types of screed systems, a joint must be formed above all structural movement joints when installing Lafarge Gvlon screeds, taking the following actions into consideration.

  • Edging strips suggested for use with Gyvlon screeds are generally 8-10mm foamed polythene skirt, this thickness relates directly to the maximum allowable positive movement within the screed.
  •  It is recommended that very large pours of floating or unbonded construction with a dimension of 30m by 40m without a break, such as a dividing wall, should include a bay joint of compressible material such as Flexcell or Ethafoam. Alternatively, on hardening, a saw cut to the full depth of the screed can be included to form the day joint.
