Pre-formed waterproofing membranes are specialized sheets or rolls used to create a water-resistant barrier in construction projects. Composed of materials like modified bitumen, PVC, EPDM, or TPO, these membranes offer superior waterproofing capabilities.
Membranes come in various thicknesses and sizes, providing flexibility for different applications for roofing, basements, tunnels, and foundation walls. This contributes to the longevity and durability of structures by preventing water ingress and protecting against moisture-related issues.
Explore our Preformed Membranes
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
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.
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.
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.
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.
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.
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.
