Sheet membrane systems are reliable and durable thermoplastic waterproofing solutions that can fulfill the requirements of even the most demanding below-ground structures, including those exposed to highly aggressive ground conditions and stress.

Sheet Membrane Systems Are a Popular Choice as They Are Designed to Withstand Exposure and Stress Extremes Such As:

High level of water pressure
Aggressive groundwater containing chemicals (sulfates and chlorides in solution)
Unequal static forces due to settlements or uplift
Dynamic forces due to earthquakes

Typical Application Fields for Our Membranes

Below-Grade Areas, Basements and Other Concrete Structures

Highly flexible membrane systems protect any concrete structure up to the highest requirements

Loose laid Sikaplan® PVC and TPO sheet membrane systems are designed for long-term durability and can be built as standard single layer compartment systems up to the active control system and highest demands.

SikaProof®, a fully-bonded TPO membrane system offers customers high waterproofing safety and installation efficiency, typically used for basements.

SikaShield® modified bituminous membrane sheets provide the most cost-efficient solution for below ground structures.

Tunnels

A tunnel structure has to be waterproofed either with a drainage system, a waterstop system or with the active control system for highest safety comprising a double layer membrane and tested by vacuum.

Sikaplan® PVC and TPO sheet membrane systems are designed for long-term durability and ease of application to meet these needs. They include accessories and special solutions down to the most complex details.

Drinking and Clean Water Storage

Waterproofing lining with loose laid TPO sheet membranes is very durable and a perfect technical solution in new construction and renovation of reservoirs.

Sikaplan® drinking water membranes fulfill the highest hygienic standards and are designed for efficient and fast application.

Pools

Lining of private or public indoor/outdoor swimming pools can be done with loose laid and peripheral fixed Sikaplan® PVC sheet membranes in various colors. For natural swimming ponds, a special TPO membrane is available.

Swimming pool tiles
Ponds

Pond linings with sheet membranes are used in potable water reservoirs for irrigation and clean water processing. Special membranes for artificial lakes and retention ponds require special sheet membranes to protect the subsoil and groundwater against pollution.

Sikaplan® membranes in PVC or FPO/TPO are perfectly suitable either left exposed or protected and ballasted.

Tank Linings

Retention pools or tanks for sewage water or chemical effluents require chemically resistant linings for protection of the subsoil and groundwater against pollution.

Depending on your specific project requirements, you may choose either Sikaplan® PVC or TPO sheet membranes.
