​MasterLife WP 910 & MasterLife WP 912 System

Hydrophillic waterbar and mastic system for construction joints.

How does the MasterLife WP 910 and MasterLife WP 912 System work?

MasterLife WP 910 is a hydrophilic waterbar, ready for installation to waterproof joints in concrete structures. The product is based on a special polymer technology that acts by swelling on exposure to water to form a seal and render the joints watertight. MasterLife WP 910 is bonded to the concrete using MasterLife WP 912 which is a one component, moisture curing pre-polymer which swells when in contact with water, suitable for the permanent sealing of construction joints in concrete structures.

What is the MasterLife WP 910 and MasterLife WP 912 System used for?

The MasterLife WP 910 and MasterLife WP 912 System is suitable for all construction joints subject to hydrostatic pressure, on one or both sides. Application areas include joints between abutments of concrete and rock, masonry, rafts and walls in tunnels and basements, steel and concrete pipes and precast elements.

What are the benefits of the MasterLife WP 910 and MasterLife WP 912 System?

• Swells in contact with water by up to 200%, preventing water ingress even when the joint width varies.

• Water molecules held by molecular attraction – captured water does not get transported through capillaries.

• Resistant to chemicals, solvents, fuels and oils.

• Controlled swelling – minimise the risk of damage to concrete.

• No air bubbles that can lead to the breakdown of the seal and allow leaks.

• Outstanding chemical resistance.

• Reversible swelling process.

• Resistant to micro-organisms formation.

• Can seal joints with up to 7 bars water pressure.
