Application

  • It protects against migration of the radioactive radon from soil into interiors
  • Designed for making an anti-moisture layer under floors, floorings or screeds
  • For moisture insulation of underground parts of buildings and foundations
  • It provides ideal protection against moisture of thermal and acoustic insulation in floor structures

Benefits

Waterproof

Durable

Quality Warranty

Flexible

Conformity with standards

Tensile strength

ASSEMBLY

The waterproof membrane, when used under floors or screeds, should be placed on a previously prepared, levelled concrete base. Then connect the waterproof membrane tightly to the horizontal insulation of the walls of the Confol Alfa foundations.

Adjust the width of the membrane in such a way as to limit the connection of membranes. However, if this is not possible, the waterproof membrane should be overlapped at least 15 cm and then glued with butyl glue. The membrane should be extended approx. 20 cm up the wall.
