Sika-Trocal Adhered Roofs

An adhered membrane could be considered for many refurbishment applications where the existing surface is sound and remains firmly attached to the substrate, or for concrete decks where the use of mechanical fasteners maybe slow and tedious. Additionally, as the membrane is exposed, any alterations are easily executed, as access is easy. Similarly, any damage is easy to spot and repair.

Sika-Trocal® SGK Adhered Roof System - S-Vap 5000E SA

12,15 & 20 year adhered roof system

  • Sika-Trocal® SGK waterproof covering
  • Polyisocyanurate foam board insulation
  • S-Vap 5000E SA vapour control layer.

Mechanically Fastened Roofs

A mechanically fastened roof is generally quick and economical to install and because of its lightness in weight, will often enable savings to be made on the supporting structure. Additionally, as the membrane is exposed, any alterations are easily executed, as access is easy. Similarly, any damage is easy to spot and repair. The wide range of fasteners now available means that it is possible to mechanically fix an exposed Sika-Trocal membrane to virtually any type of deck.

Ballasted Roofs

A ballasted (gravel/paved) roof will generally require a stronger supporting structure than that for the exposed membrane one, but will allow the roof to be used as a trafficked or leisure use area.

12, 15 & 20 year ballasted roof system:

  • Ballast surface protection
  • S-Felt T 300 or Sika-Trocal® SBV upper protection layer
  • Sika-Trocal® SGmA waterproof covering
  • Polyisocyanurate foam board insulation
  • S-Vap 5000E SA vapour control layer
