MasterSeal 910

Hydroswelling Waterbars That Are Installed into Cold Joints to Render the Joints Leak-Proof

How Does MasterSeal 910 Work?

MasterSeal 910 is a hydro swelling water bar, 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 do 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 with no air bubbles to break down and allow leaks

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