Sheet membrane systems are reliable and durable 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 Waterproofing Membrane Systems Are a Popular Choice, as They Are Designed to Withstand Exposure and Stress Extremes Such As

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

Sika’s Sheet Waterproofing Membrane Systems Have Many Advantages

  • Sikaplan® PVC and TPO highly flexible sheet membrane systems protect any concrete structure - can be built as standard single layer compartment systems up to the active control system to meet the highest demands.
     
  • SikaProof®, a fully-bonded TPO membrane system, offers customers high waterproofing safety and installation efficiency and is typically used for basements or below-grade areas.
 
  • SikaBit®  self-adhered bituminous modified sheet membranes, provide a cost-efficient solution for basements and below-grade structures
     
  • We provide accessories and special detailing solutions down to very complex details.

  • Resistant to many different chemicals, our sheet membrane systems ensure high protection to the concrete, against aggressive gases as well as brackish water and saltwater.
 
  • With the Sikaplan® system the water tightness can be guarenteed before concreting and backfilling throught high quality control on site with double welded seams, which can be tested with compressed air vacuum or electronic detectors.
     
  • Very high flexibility of both Sikaplan® and and SikaProof® sheet membranes allow easy installation and completion of details that results in faster membrane installation.
 
  • Fast application is possible even at low temperatures, as neither of our Sikaplan® or Sikaproof®  solutions require any curing/waiting times nor primers.
 
  • Long-term track record with over 45 years of experience and extensive test reports confirm high performance, security and reliability of Sika membrane waterproofing systems, which ensures a very long service life of the waterproofed basement or below-grade structure.

Typical Application Fields for Our Membranes

Below-Grade Areas, Basements and Other Concrete Structures
