MasterSeal 910 - Hydroswelling waterbars for joints


How does MasterSeal 910 work?

MasterSeal 910 is a hydroswelling waterbar, ready for installation in cold joints to render the joints leak-proof.

MasterSeal 910 is recommended for all construction joints exposed to hydrostatic pressure.

Application areas include joints between:

  • Abutments of concrete and rock, masonry, etc
  • Rafts and walls in tunnels and basements
  • Steel and concrete pipes, precast elements etc

 

What makes MasterSeal 910 a unique solution?

It is based on a blend of acrylate polymers and a unique hydroswelling polymer that acts by swelling on exposure to water, to form a seal.

 

What are the benefits of MasterSeal 910?

  • Swells in contact with water by up to 150% - prevents water ingress even when the joint width varies

  • Water molecules held by molecular attraction – captured water does not get transported through capillaries thus stopping further water ingress

  • Controlled swelling – swelling pressure insufficient to damage concrete

  • Does not form foam or gas with water – water absorption creates a durable seal.  No air bubbles to breakdown and allow leaks

  • Reversible swelling process – will reabsorb water after dry periods and accommodate minor movements in the structure
