MasterSeal 7000 CR – Protection and waterproofing for extreme wastewater facilities conditions
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.
Prolong wastewater facilities concrete structures’ life cycle
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.
Fast and easy application by rolling or spray at temperatures from 5oC to 35oC
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, suits 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.
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
