    MasterSeal 7000 CR - The best solution for extreme wastewater challenges

    Please contact us for free consultation

    Proven durability: The concrete infrastructure of wastewater treatment systems is subject to complex physical and chemical attacks. MasterSeal 7000 CR is specially designed to address these challenges.

     

    Unique Combination of Application and Performance Properties 

    MasterSeal 7000 CR's high resistance to abrasion and biogenic sulfuric acid corrosion are ideal to withstand the severe conditions that occur in pretreatment and aeration tanks, digesters, or sewers. Its dynamic and static crack-bridging abilities protect concrete from cracks thus prolonging the structure's life cycle.

    Product properties

     Fast and easy application by rolling or spray

     Excellent curing properties, which reduce downtime

     Specific chemical resistance, including high concentrations of biogenic sulfuric acid

     Crack-bridging for gaps of up to 0.7 mm

     Maximum moisture tolerance, including application on humid substrates


     


    Fast and Easy application – even on humid substrates

    The easy application of MasterSeal 7000 CR by spray or roller, as well as its compatibility with damp substrates, suit the conditions of wastewater facilities particularly well. Downtime – which is always critical when stopping a wastewater process – is also reduced because of its fast-curing properties that allow contact with water only 24 hours after application at 20oC.

    For maximum application performance do not apply at temperatures below +5°C nor above +40°C. For higher temperatures consult Master Builders Solutions​ Technical Services department.

    Challenges in wastewater Treatment

     

    1. Strong waterflow and water containing solid particles > Abrasion

    2. Concrete shrinkage and steel reinforcement corrosion > Cracks, leakage and structural damage

    3. Presence of chemicals and conditions for Biogenic Sulfuric Acid > Chemical attack

     

    Increase the life cycle of the structures and reducing maintenance and repair


     


    Fields of application

    • Urban and industrial wastewater treatment both in inflow and outflow areas
    • Biogas plants
    • Secondary containment in industry
    • Sewage effluent pipelines
