Best Uses

Sika BentoShield Max LM is best used as a damp proofing, water proofing, tanking membrane for horizontal and vertical applications where buildings are expected to be subject to hydrostatic water pressure. It is also used on 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.

Application

The membrane is designed to work under confinement. When placing Sika® BentoShield® Max LM inside the formwork, the formwork must be removable & not
the stay in-situ variety. Sika® BentoShield® Max LM products are not designed to be installed over ice or in standing water. Should the ground water contain strong acids, alkalies, or has a conductivity of 2,500 μmhos/cm or greater, water samples should be tested for compatibility. Rolls may compress slightly during storage. Membrane
can be shaken once unrolled to return to their full length.

Sika® BentoShield® Max LM may be combined with other Sika products.
