OC-Plan 1018 ECB Geomembrane

Definition :
OC-Plan 1018 is a signal foiled ECB (Ethylene Copolymer Bitumen) geomembrane with very high ageing resistance

Areas of Application :
OC-Plan 1018 is used for the water proofing of foundations, walls, terrace and green roofs, ponds, irrigation channels, water storage units, below ground parking lots

Advantages :

  • Unlike the traditional bitumen membrane system, applied in single layers
  • Environmental friendly (PVC, plasticizer and chlorine free, no toxic gas during application)
  • High tensile, tear and puncture resistance
  • Preserves dimensional stability under heat changes
  • Root resistant
  • Minimum risk at application due to the usage of automatic hot welding machines
  • Resistant to sparks
  • Resistant to various acids, alkalis and sea water
  • Loose laying and double seam welding system provides the seams to be tested with pressure
  • Visual test possibility for surface damages with the signal foil lamination
  • Application possibility in all weather conditions
  • The existing geomembrane can be welded homogeneously with the new geomembrane
  • Highly resistant to solar radiation, UV lights and ozone
  • XPS, EPS and bitumen compatible, no need for seperation layers, can be in direct contact
  • Highly resistant to ageing, does not loose any properties by time
  • Can be applied directly on any existing bitumen membrane system
  • OC-Plan 1018 ECB Geomembranes have an international product insurance of 10 years

Special Conditions Requiring Attention :

  • OC-Plan 1018 must be applied by experienced and licenced applicators
  • Drainage system must be working properly
  • The welding temperature of the automatic hot welding machine must be arranged correctly
  • The double welded seams must be tested by pressure using a manometer. 2 bar pressure must be given to the seam by 2 minutes and no pressure lost must be observed from the manometer
  • After the visual tests are performed on the signal foil, if a damaged surface is observed, a patch must be applied on the damaged surface by hand welding tools.
  • After all the tests are performed, each section of application must be handed over to the control engineer of the client
  • The handed over sections must be protected by the client and the necessary hints must be given accordingly
  • The fixings must be done properly; for wall applications - above ground level, for roofs - fixings must be on the parapets

  • Polyfin AG is a CE and ISO certified producer.
  • OC-Plan 1018 ECB Geomembrane is produced according to the DIN EN 13967 norms.
  • It is an environmentally friendly material

Accessories :
OC-PLAN 1018 system has special ECB accessories. These are internal/external corners, roof ventilators, roof outlets, water outlets, sealing sleeves, vantilation pipes, metal sheets, etc. These accessories are connected to the ECB geomembrane system using hand welding tools. This way the continuity of the waterproofing system is protected.

Storage :
Vertical storage is suggested

Shelf Life :
The shelf life of the material is indefinite

Amount of Material Required :
When doing the initial calculations for the amount of material required in a project, it is suggested to add 5% for the seam losses and 2-5% for the possible wastage according to the site conditions.
