• 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.
