Flexible, sheet-based waterproofing membrane based on flexible polyolefin (FPO), with special embossing on the surface. Membrane thickness 1.2 mm. Together with SikaProof Adhesive-01, it forms a full-surface, SikaProof P-1201 underground insulation system. The SikaProof P-1201 system is glued on the construction site, an adhesive layer is applied to the hardened substrate and the membrane is placed over it. The system is laid cold.

Features

• full-surface adhesion to a hardened reinforced concrete structure
• no water penetration between the concrete and the membrane
• high flexibility and ability to cover cracks
• high water resistance
• easy installation, tight connections (no welding)
• laid cold (does not require welding or use of open fire)
• good tear and impact resistance
• temporary resistance to weathering and UV radiation (during installation)
• durable and resistant to aging
• resistance to aggressive factors occurring naturally in soil and groundwater
• Can be combined with other approved Sika insulation and sealing systems

Application

It is used for anti-moisture and anti-water insulation as well as for securing concrete of underground structures with buildings and other structures located below the ground level against the ingress of groundwater. It is used for the insulation of: vertical walls of reinforced concrete, horizontal reinforced concrete slabs, ceilings, offsets and plinth, during the extension, reconstruction and repair of the object in, prefabricated structures.
