MasterSeal 909

RE-INJECTABLE HOSE SYSTEM FOR CONSTRUCTION JOINTS IN CONCRETE

Description

MasterSeal 909 is an advanced injection hose system for installation in construction joints, ready for subsequent injection of cementitious or polymeric compounds to ensure watertightness. It is not affected by low temperature and immersion in water.

Uses

MasterSeal 909 is recommended for use in construction joints in all structures, which need to be injected to waterproof them, such as:

Water retaining structures

Tunnels and basements

Buildings, bridge decks and other similar structures

MasterSeal 909 is not recommended for use in expansion joints and in areas prone to significant settlements.

Advantages

Hose is re-injectable – permits re-injection if leakage persists or reappears at a later date.

Neoprene strips act as “one way valves” (fig 2) – prevents injection material from returning even under back pressure allowing for the hose to be cleaned and ready for later use.

Solid inner core – does not collapse under concrete pressure and allows smooth flow of injected material.

Chemically inert – does not deteriorate even if exposed to such injection materials as polyurethanes, vinyls esters, epoxies and cements.

Flexible – easy installation at corners without cutting and jointing.
