Description

Sika BentoShield® MAX LM is a self healing waterproofing membrane that’s resistant to contaminated soils, forming an automatic mechanical bond to freshly poured concrete it virtually eliminates the possibility of water movement between the membrane & structure. Approximately 6.5 mm thick, consisting of two polypropylene geotextiles, a woven fabric and non-woven fabric, enclosing prehydrated homogeneous layer of granular sodium bentonite at a minimum weight of 5000g/m². The two geotextiles are interlocked by a needle-punching process forcing fibres from the non-woven layer through and beyond the woven layer. This process contains and confines the polymer modified bentonite granules and forms a physical link between the geotextiles. A flexible polyethylene layer is integrally bonded to the non-woven geotextile.

Uses

  • Damp proofing, water proofing, tanking membrane for horizontally and vertical applications where buildings are expected to be subject to hydrostatic water pressure.
  • Below ground reinforced concrete structures
  • Effective against diaphragm wall constructions.
  • Direct application onto ground retaining concrete piling when placed within the piling - concrete interface
  • Direct application within steel sheet piling – concrete interface
  • Can be placed within the formwork.
  • Below structural reinforced concrete slabs.

Advantages

  • Qualified waterproofing tanking membrane in accordance with BS8102: 2009
  • Water tightness of the laps tested to BS EN 1928.
  • Designed to offer protection in areas subject to changing geological conditions such as flood plains, areas of soil settlement and brown field constructions.
  • Application ensures performance stability in high water table environments and constructions which are subject to future alterations in water levels.
  • An effective barrier against ground water in saline environments.
  • Easy to install, no primers required.
  • Easy to install, no protection boards required.
  • Can be applied in temperatures below 0°C
  • Will self heal when subjected to a head of water.
  • Can be applied during conditions of high humidity.
  • Major constructions benefit from speed of application.
