System information

System structure

The following products must be considered for use depending on roof design:

  • Sikaplan® TD-15 KR Sheet for detailing
  • Sarnafil® TS 77 strips
  • Sarnafil® T Metal Sheet
  • Sarnafil® T Welding Cord
  • Sarnabar® / Sarnafast®
  • Sarnafil® T Prep / Sarnafil® T Wet Task Set
  • Sarnacol® T 660
  • Solvent T 660
  • Sarnafil® T Clean

Wide range of accessories is available e.g. prefabricated parts, roof drains, scuppers, walkway pads and decor profiles.

Compatibility

Sikaplan® TM-15 (KR) may be installed on all thermal insulations and levelling layers suitable for roofing. No additional separation layer is required.

Probably a fire protection layer is necessary.

Sikaplan® TM-15 (KR) is suitable for installation directly on top of existing, carefully cleaned, levelled bituminous roofing, e.g. re-roofing over old flat roofs. Colour changes in membrane surface may occur if in direct contact with bitumen.

Application steps

EQUIPMENT

Hot welding overlap seams

Electric hot air welding equipment, such as hand held manual hot air welding equipment and pressure rollers or automatic hot air welding machines with controlled hot air temrerature capability of a minimum 600°C.

Recommended type of equipment:

Manual : Leister Triac

Automatic : Leister Varimat

Semi-automatic : Leister Triac Drive

 

SUBSTRATE QUALITY

The substrate surface must be uniform, smooth and free of any sharp protrusions or burrs, etc. Sikaplan® TM-15 (KR) must be separated from any incompatible substrates / materials by an effective separation layer to prevent accelerated ageing. The supporting layer must be compatible to the membrane, solvent resistant, clean, dry and free of grease and dust. Metal sheets must be degreased with Solvent T 660 before adhesive is applied.

APPLICATION

Installation procedure

Reference must be made to further documentation where applicable, such as relevant method statement, application manual and installation or working instructions.

Fixing method - General

The waterproofing membrane is installed by loose laying (without stretching membrane or installing under tension) with mechanical fastening in seam overlaps or independent from overlaps. Overlap seams are hot welded using specialised hot air equipment.

Fixing method-Spot fastening

Sikaplan® TM-15 (KR) must always be installed at right angles to the deck direction. Sikaplan® TM-15 (KR) is fixed by fasteners and washers/tubes along the marked line, 35 mm from the edge of the membrane. Sikaplan® TM-15 (KR) is overlapped by 140 mm. The spacing of the fasteners is in accordance with the project specific Sika calculations. At upstands and at all penetrations, the membrane must be secured by additional fasteners and washers/tubes. That protects the Sikaplan® TM-15 (KR) roof covering against tearing and peeling off by winduplift.

Hot welding method

Overlap seams must be welded by electric hot welding equipment. Welding parameters including temperature, machine speed, air flow, pressure and machine settings must be evaluated, adapted and checked on site according to the type of equipment and the climatic conditions prior to welding.

Testing overlap seams

The seams must be mechanically tested with screwdriver or steel needle to ensure the integrity/completion of the weld. Any imperfections must be rectified by hot air welding.
