Roof Decks - New Build & Strip Off

Suitable deck’s for use beneath Sika Liquid Plastics roofing systems include (Subject to any priming requirements);

 

  • Profiled Metal Sheets
  • Plywood
  • Oriented Strand Board (OSB)
  • Timber
  • Wood Wool Cement Slab
  • Precast and lightweight aerated concrete

 

Options

  • Waterproofing Only: Specified system applied to the new roof deck directly following all necessary calculations and priming requirements.
  • Thermal Upgrade: As required or to meet building regulations/avoid condensation risk.

Substrates - Refurbishment

Suitable substrates for use beneath Sika Liquid Plastics roofing systems include (Subject to any priming requirements);

 

  • Asphalt
  • Bituminious Felt
  • Single Ply Membranes
  • EPDM
  • Coating/Solar Reflective Coatings
  • GRP

 

Options

  • Waterproofing Only: Specified system applied to the existing roof coverings. U Value calculations will be carried out in order to establish if a condensation risk is present, this is based on core samples taken from the existing build-up and a full roof survey.
  • Wind load calculations will be carried out to determine if the existing build-up is sufficiently secured to the structure prior to overcoating.
  • Thermal Upgrade: As required or to meet building regulations/avoid condensation risk. The existing insulation (if present and in a suitable dry condition) will be incorporated into the calculation, this will reduce the thickness of new insulation required to meet building regulations.
