CONTRACT SERVICE

GOES FROM STRENGTH

TO STRENGTH

For over 30 years Steve Vick International’s Contract Service teams have been
working around the UK, Europe and further afield providing a broad and

expanding range of services from cutting large diameter pipes and performing
complex gas pipe repair and renewal operations to sealing off abandoned drains

and filling all types of underground pipes and voids

needs to be filled to prevent the sleeve
cracking in the future and thus ensure the
integrity of the road surface.
Recent projects have involved SVI using
a quick-set structural cementitious grout
to fill the annular space in two 100m
sections as well as several shorter 30 to
60m lengths. The premeasured quantity
of grout was mixed on-site in SVI’s
colloidal screw grout mixer and gravity-
fed into the void. The grout can be fed
under pressure if required. The work will
continue well into 2019.
