Sika BentoShield® MAX LM

Fully-bonded, self-healing, mechanically bonded, contaminate-resistant waterproofing membrane. It is a pre-hydrated, needle-punched, PE-flexible membrane that combines the swelling performance of sodium bentonite with high-strength polypropylene geotextiles. The bentonite clay component can swell, sealing cracks and minor holes and forming an impermeable layer.

Benefits:

• High-performance watertight sealed lap, tested to BS EN 1928.

• Self-healing, puncture-resistant natural sodium bentonite tanking, tested to BS 8102.

• A flexible polyethylene layer is integrally bonded to the non-woven geotextile.

• Polymer-modified BBA-accredited barrier system, designed to resist contaminated and saline ground water.

• Laminated low-density polyethylene (LDPE) layer provides protection against climate and environmental variations.

• Automatic mechanical bond to freshly poured concrete eliminates water tracking.

• Can be applied in temperatures below freezing.

• Ten-year guarantee when used as a single system.

• 15-year guarantee when used in dual system with Sika Watertight Concrete or Sika Cavity Drainage System.
