MasterRoc MP 307 CE – Low viscosity, fast reacting acrylic resin for permanent water sealing and layer curtaining of concrete and masonry

How does MasterRoc MP 307 CE work?

MasterRoc MP 307 CE is a highly reactive twocomponent 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. MasterRoc MP 307 CE is especially designed for concrete repair and is CE certified according to EN 1504-5.  

Where is MasterRoc MP 307 applied?

  • Concrete repair - swelling fitted filling of cracks and fissures (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

What are the advantages of MasterRoc MP 307 CE?

  • Upon curing forms a highly flexible compact resin with good adhesion properties even on damp and wet surfaces.
  • Due to the special latex emulsion of Part B the cured system is rubber-like and strong but still extremely flexible. 
  • Very low viscosity (close to water) allows 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%).
  • 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.
