ULTRASEAL® XL - Active polymer waterproofing membrane

An active polymer waterproofing membrane, suitable in a wide range of ground contaminates, including high-saline

conditions. Unlike passive membranes when used alone, the self-sealing ability of the active XP technology enables the ULTRASEAL® XP waterproofing membrane to seal minor cuts or damage to the membrane.

Features and benefits:

• Suitable as waterproofing protection for structural concrete surfaces under continuous hydrostatic and non-hydrostatic or intermittent hydrostatic conditions, including high-saline and contaminated environments.
• Works by forming a low permeability membrane upon contact withwater.
• When hydrated, the unconfined membrane can swell many times its dry volume.
• When confined by backfill or concrete the swell is controlled, forming a dense, impervious waterproofing membrane.
• This swelling action can seal small concrete cracks caused by ground settlement and concrete shrinkage.
• When concrete is poured against the XP geotextile side, ULTRASEAL® XP forms a strong mechanical bond.
• Contains zero VOCs, and can be installed in almost any weather condition directly to green concrete.
• The membrane can be continued under the floor slab to provide a continuous, uniform waterproofing system.
