MasterJoint 910

Acrylic hydroswelling waterbars for construction joints

How Does MasterJoint 910 Work?

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

MasterJoint 910 is recommended for all construction joints exposed to permanent or temporary hydrostatic pressure by ground water, run-off water and/or surface water. It’s Suitable for freshwater and saltwater.
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 MasterJoint 910 a Unique Solution?

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 MasterJoint 910?
  • User friendly- easy to apply on different substrates

  • Swells in contact with water by up to 300% - 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.

  • Self-injecting function- penetrating cracks and voids.

  • 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 – swelling process is infinitely often repeatable, often reversible;Dimensionally stable even at high temperatures.
