SURFASSEAL Bentomax C is a sodium bentonite-based Geosynthetic Clay Liner (GCL) waterproofing membrane, designed for use in below-ground reinforced concrete structures.Consists of a bed of sodium bentonite granulated powder encapsulated between a high tensile woven polypropylene liner and a non-woven fabric liner, which are stitched together using a patented needling process.Penetrating water causes the sodium bentonite granulates to hydrate and swell, producing an impermeable membrane which is self-healing, and can seal any small cracks in the concrete. Overlaps should be detailed using SURFASSEAL-Bentonite Powder.Features and benefits:Tough and resistant.Demonstrates self-healing properties.Higher puncture and tear resistance compared to conventional foils and coatings.Quick and easy to install without complicated welding equipment.Can be installed in every season, independently of temperature and weather conditions.Quality control tested to ensure consistently high quality.May be installed pre-form or post-form.Available in two sizes: 6.375 m² (1.25 x 5.1 m) and 38.25 m² (2.55 x 15 m) rolls.CE marked.Technical characteristics:Thickness to EN ISO 9863-1: 7.4 mm.Index flux to ASTM 5887: 3,0 x 10-9 m³/m²/s.Permeability to ASTM 5887: 1.8 x 10-11 m/s.Tensile strength MD to EN ISO 10319: 10.4 kN/m (-10%).Tensile strength CD to EN ISO 10319: 8.5 kN/m (-10%).Grab strength to ASTM D 4632: 667 N (-10%).CBR puncture strength to EN ISO 12236: 2.5 kN (-10%).Peel adhesion to concrete to ASTM D 903 Mod: ≥2.5 kN/m.Peel strength to ASTM D 6496: 66 N/10 com (-10%).- Mass per unit area (average):Carrier layer, PP woven: 130 g/m².Inlay, Sodium Bentonite: 5000 g/m².Cover layer, PP nonwoven: 200 g/m².Total weight to ASTM D 5993: 5330 g/m².- Bentonite properties:Montmorillonite content to CUR 33: ≥75%.Swelling capacity to ASTM 5890: >24 ml/ 2g.Moisture content to DIN 18121-1 and -2: 12% (maximum).

SURFASSEAL Bentomax C is a sodium bentonite-based Geosynthetic Clay Liner (GCL) waterproofing membrane, designed for use in below-ground reinforced concrete structures.

Consists of a bed of sodium bentonite granulated powder encapsulated between a high tensile woven polypropylene liner and a non-woven fabric liner, which are stitched together using a patented needling process.

Penetrating water causes the sodium bentonite granulates to hydrate and swell, producing an impermeable membrane which is self-healing, and can seal any small cracks in the concrete. Overlaps should be detailed using SURFASSEAL-Bentonite Powder.

Features and benefits:

  • Tough and resistant.
  • Demonstrates self-healing properties.
  • Higher puncture and tear resistance compared to conventional foils and coatings.
  • Quick and easy to install without complicated welding equipment.
  • Can be installed in every season, independently of temperature and weather conditions.
  • Quality control tested to ensure consistently high quality.
  • May be installed pre-form or post-form.
  • Available in two sizes: 6.375 m² (1.25 x 5.1 m) and 38.25 m² (2.55 x 15 m) rolls.
