Sika - SikaProof P-12 self-adhesive waterproofing membrane

Self-adhesive, polyolefin waterproofing membrane, adhering to the entire surface, placed on the constructed structure. Made on the basis of flexible polyolefins (FPO), it is intended for the insulation of underground structures. It is covered with an adhesive-sealing layer secured with a protective layer. It is applied cold, removing the protective layer and gluing the membrane to the hardened concrete substrate primed with SikaProof Primer-01.

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 the use of open fire
• temporary resistance to weathering and UV radiation (during installation)
• durable and resistant to aging
• resistant to aggressive factors occurring naturally in soil and groundwater
• May be combined with other approved Sika insulation and sealing systems

Application

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