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
