MasterRoc MP 707

Low Viscosity, Fast Reacting Acrylic Resin for Permanent Water Sealing and Layer Curtaining of Concrete and Masonry

How Does MasterRoc MP 707 Work?

MasterRoc MP 707 is a highly reactive two-component acrylic sealing resin with a low viscosity for good penetration. The product cures quickly, forming a rubber-like resin with the ability to withstand certain ground and crack movement.

Recommended Uses:

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

• Curtain injection

• Concrete repair - swelling fitted filling of cracks and fissures

• Stopping of minor water inrush through cracks

• Ground stabilization

What Are the Unique Features of MasterRoc MP 707?

Upon curing MasterRoc MP 707 forms a highly flexible compact resin with good adhesion properties even on damp and wet surfaces.

What Are the Benefits of MasterRoc MP 707?

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

• Controlled gel time between 3 and 22 minutes at 20◦C.

• 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%).

• Workable between 5◦C and 40◦C.

• Neither the liquid nor the cured resin is corrosive and is therefore suitable for reinforced concrete structures.

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

• Environmentally friendly: harmless in contact with groundwater and does not emit any dangerous substances.
