|Multiject Test - 000830
Test Date: August 30, 2000
Test Location: Underground Services (1983) LTD. - Bolton,
Test Goals: To determine if
Multiurethanes Multiject injection hose system is suitable for use with
Spinor A12 Microfine cement as stated in the manufacturers literature.
Mixing Equipment: 1L4 Portable
high speed mixer complete with Moyno Pump.
Injection Material: Spinor A12
microfine cement was mixed for 5 minutes using a 2:1 water to cement
Injection Hose: A 15 foot length
of Multiject injection hose was equipped with 1 meter lengths of
1/4" extension tubing at each end.
Results: At a pressure of 25 PSI,
select Multiject valves opened and microfine exited. At a pressure of 50
PSI, all of the Multiject valves were open and microfine was dispensed
evenly along the full length of the injection hose.
Conclusion: The tests provided
live confirmation of the manufacturers statements that Multiject is a
suitable injection hose system to deliver Spinor A12 microfine cement.
Also, given the valve opening pressure requirement determined by the
tests to be > 25 PSI, Multiject's valve construction outperforms
other competitive re- injectable hose systems presently available, in
it's ability to be thoroughly flushed at pressures of < 25 PSI after
