As the specialist in the treatment, protection and repair of concrete, Contreat works using Xolutec technology: an innovative and intelligent way to provide durable waterproofing and protection of concrete structures in extreme circumstances that require high chemical-resistance.
The power of Xolutec
Xolutec is a new dimension in durability. The two-component crack-bridging membrane MasterSeal M 790 based on Xolutec technology, provides seamless waterproofing for the inflow and outflow areas of water purification plants, sewage pipelines, biogas plants and secondary containments (reservoirs).
The MasterSeal M 790 coating can be used on a range of surfaces, both inside and outside, dry or wet: on horizontal and vertical surfaces, on concrete, cement-based mortar and steel surfaces and on reinforced concrete, against chemical attack, corrosion and carbonation.
5 benefits of Xolutec
Cures fast: even at low temperatures, so it can be used quickly
Insensitive to light
Can be used in diverse treatment circumstances, less chance of delays or defects
Long maintenance cycles & lower life-cycle costs: considerable reduction in the total installation costs
Low VOC content, quick application
The water that flows through the pipes, contains sulfur compounds which are converted by bacteria into hydrogen sulfide (H2S), which then escapes in the sewage water 1.
This gas can be oxidised by other bacteria, creating sulfuric acid (H2SO4), which attacks concrete due to its very low pH-value. This phenomenon is known as biogenic sulfuric acid corrosion 2.
These acid attacks occur in the top part of the sewers and can reduce the thickness of unprotected concrete by 6 to 12 mm per year.
