MasterRoc MP 307 CE

Highly reactive, two-component acrylic sealing resin. Used for the permanent water sealing and layer curtaining of concrete and masonry, with a low viscosity for good penetration.

Features and benefits:

• Fast-curing, forming a rubber-like resin with the ability to withstand certain ground and crack movement. This highly flexible, compact resin has good adhesion properties (even on damp and wet surfaces).

• Due to the latex emulsion of Part B, the cured system is rubber-like and strong, but remains flexible.

• Very low viscosity (close to water), which allows for deep penetration at low pressure into very fine cracks or fissures and long flow paths.

• Withstands a permanent water pressure of more than 12 bar.

• Superior flexibility (elongation at break >300%), enabling balance of ground movements or settlements.

• Not sensitive to water and always stays close to its original shape (maximum change of mass: -15% to +20%).

• Non-corrosive, and therefore suitable for reinforced concrete structures.

• Good chemical resistance against acids, bases, solvents, and fuels.

• Harmless in contact with groundwater and does not emit any dangerous substances.

Application:

• Concrete repair - swelling fitted filling of cracks and fissures (to EN 1504-5: Category S).

• Curtain injection.

• Permanent water sealing of tunnel and shaft concrete linings and masonry.

• Stopping of minor water inrush through cracks.

• Injection hose applications.

• Ground stabilization.

Equipment can be cleaned of uncured material using water with a detergent if possible.
