5System advantagesCEMflex Active WaterstopActive construction joint sealingSimple Design and applicationtwo installation methods: install prior to concrete placement or inserted into the fresh concreteHighly effective waterproofing verified and certified byindependent test laboratoriesActive Crystallizationthe active crystallization process repairs cracks in the construction joint for the lifespan of the concreteCEMflex active waterstop consists of a steel plate waterstop coated with a patented mineral coating, which actively reacts with alkaline water when embedded in concrete to provide a watertight construction joint. CEMflex steel plate waterstop funcas both an active and passive barrier to the transmission of water through non-movement construction joints, both horizontal and vertical, in reinforced concrete structures. CEMflex active waterstop has been proven, through independent testing, to be effective up to 5 bar (50 m) water pressure. CEMflex unique design makes it the safest, most cost-effective, and reliable waterstop available on the world market.

6How the crystallization process worksCEMflex steel plate mineral coating reacts to the alkaline in the concrete. This provokes the natural formation of free limestone, which penetrates and seals cracks in the the concrete.System advantagesHow the CEMflex Active Waterstop worksThe active crystallization process ensures watertight construction jointsOnce embedded in concrete, the CEMflex active mineral coating reacts to the alkalinity of water in the concrete to form Calcium Hydroxide (free lime) which supports the natural self-healing (sintering) of concrete, by crystallizing to penetrate and seal cracks in the construction joint. The CEMflex active mineral coating has infinite sealing capability. Should alkaline water meet the steel plate, the mineral coating will continue to reactivate and repeat the self-healing, crystallization process.This has been proven through independent laboratory testing which has rated the CEMflex for 100 year service life.

7System advantagesPhysical barrierCEMflex steel plate waterstop is cast centrally along the construction joint. The steel plate creates a physical barrier which prevents the transmission of water.The crystallization process under the microscopeYou can observe the active self-healing process of CEMflex under a microscope. When the crystallization of the coating takes place, calciumhydro-xy-based crystalline fibres and needles are created. Unlimited sealing capacityThe sealing process is reactive any time alkaline water meets the mineral coating. The active coating will continue to reactivate during the lifetime of the concrete.CrystallizationFresh concrete activates the mineral coating on the plate causing the coating to soften, crystallize and penetrate any cracks in the concrete. The connection of the mineral coating to the concrete prevents waterflow through the construction joint.

8System advantagesSimple and economic handlingTwo simple installation methods1. CEMflex 2.00 m x 1.50 m coated steel plates2. CEMflex clip3. Omega holderCEMflex active waterstop can be used for all non-movement construction joints, slabs and walls, vertical and horizontal applications. The CEMflex is simple to handle, there is no preparation work and no special installation tools are required. CEMflex elminates cutting, welding, or bonding of waterstops. Additionally, CEMflex is fully weatherproof system and can be installed in wet and dry conditions. CEMflex waterstop consists of only three simple core components:

Installation prior concrete placementInstallation during concrete placement9System advantagesIt is also possible to insert the CEMflex steel plate into the freshly poured concrete. The CEMflex steel plate are inserted in the middle of the construction joint requiring a minimum 30 mm embeddment in the fresh concrete.Use clips to secure 50 mm overlap.The CEMflex steel plate is installed in the middle of the construction joint requiring a minimum 30 mm embedment. CEMflex steel plates are fixed to the reinforcement prior to concrete placement and secured at the 50 mm overlaps with Omega clips.Installation GuidelnesCEMflex steel plates are cast along the center of the construction joint and require a minimum 30 mm embedment into the concrete. To extend the waterstop simply overlap the steel plates by 50 mm and secure with a CEMflex clip or with the omega holder, depending on the installation method.Site Installation ExampleCEMflex simple handling and installation methods can save up to 80% labour costs.
