FIELD: construction activities.
SUBSTANCE: present invention relates to a multilayer membrane (100). The multilayer membrane (100) for construction work configured for installation between the wall (8a) of the support socket (8) formed in the ground (9) and the concrete structure (5), and containing the first layer (1) of a thermoplastic polymer material, impermeable or essentially impermeable to water, and the second layer (2) of thermoplastic polymeric material, impermeable or essentially impermeable to gaseous methane and/or gaseous radon and/or volatile organic compounds (VOC), attached to the first layer (1) and configured for placement between the specified first layer (1) and the concrete structure (5) when installing the membrane (100).
EFFECT: construction membrane is provided which can be placed between soil and a concrete structure to protect the concrete from water and gases possibly present in the soil, and which can be at least for the most part easily recycled.
