MASTERFLEX 900 

MASTERFLEX 900 is an advanced injection hose system for installation in construction joints, ready for subsequent injection of cementitious or polymeric compounds to ensure watertightness.
The hose construction is tough, flexible, resilient and chemically inert. It is not affected by low temperature and immersion in water.
The unique hose has a solid blue inner core with a longitudinal injection hole.  Three moulded grooves run along its length with a number of 3 mm diameter openings on each of them at 10 mm staggered intervals. Closed cell neoprene strips cover the three grooves and act as one way valves. The entire system is held together by a wide meshed nylon fabric sleeve.

MASTERFLEX 900 is recommended for use in construction joints in all structures, which need to be injection grouted to waterproof them, such as:

• water retaining structures
• tunnels and basements
• buildings, bridge decks and other similar structures

MASTERFLEX 900 is not recommended for use in expansion joints and in areas. prone to significant settlements.
