WILOTEKT-PLUS

FULLY BONDED HOT MELT, STRUCTURAL WATERPROOFING ON REINFORCED CONCRETE ROOF DECK

WILOTEKT®-PLUS is a unique, second generation structural waterproofing hot melt system that has been successfully used on the mainland of Europe for many years. Manufactured by COLAS, WILOTEKT-PLUS comprises a 7 mm thick tough, flexible, self-healing reinforced rubberised compound for use over concrete in protected membrane (inverted) constructions for roofing, podium decks, car parks, roof gardens, civil engineering. European Technical Approval No ETA-03/0049 applies.

Applications


  WILOTEKT-PLUS is designed to be used without screeds on concrete decks with slopes from 0° to 2.5°. Omission of screeds eliminates curing time and reduces weight loadings. Installation is also possible on some timber substrates.
  A high performance bitumen compound enabling easy application around roof penetrations and details.
  One simple specification suitable under all types of covering.
  Suitable for use on new build or renovation projects.

Performance


  Designed for the lifetime of the structure and available with a 35 year PLATINUM Guarantee virtually eliminating future replacement costs.
  WILOTEKT-PLUS is applied in a liquid state to the deck filling all cavities in the concrete surface. As a consequence there is no risk of water tracking beneath the membrane and because it is monolithic there is no possibility of lap failure.
  The compound remains flexible throughout its life meaning that minor damage will self heal.
  Stabilised polyester reinforcement ensures stability with no shrinkage, high tensile strength and excellent point loading characteristics.
  Indicative BRE Green Guide 2008 rating: D/C.
See the full details of the BRE Green Guide methodology.

Note - The environmental rankings are based on Life Cycle Assessments using BRE's Environmental Profiles Methodology 2008 and refer to the complete system build up including structural elements, thermal insulation, waterproofing and protection.

Roof deck


  Reinforced concrete laid in accordance with BS 8217:2005.
  Axter does not recommend the use of screeds to create falls as WILOTEKT-PLUS is approved for laying on 0° falls. If screeds are to be specified then they should be installed in accordance with BS 6229:2003 and be allowed to dry out before laying any reinforced bitumen membrane roofing. Lytag based screeds should not be specified.

Insulation


  Suitable for laying under HYDROSHIELD EPS or HYTHERM XPS extruded polystyrene insulation and all finishes.

Surface options


  WILOTEKT-PLUS can be used in all protected membrane (inverted) constructions; podium decks, car parks, roof gardens, civil engineering applications, macadam, brick or block pavers.

Installation


  Details can be installed first allowing other trades to continue to work.
  Installed by accredited Axtershield Installers.
  Comprehensive long term (35 year) guarantees covering product, system design and installation.
  Requires minimal routine maintenance, see Axter's recommended Maintenance Schedule.
