high quality casting ductile iron grouting sleeves for rebar connecting  



What does Grouting Sleeve mean?

Grouting sleeve is used for trenchless spot repair of gravity sewer pipes. It has a stainless steel structural core and is expandable. This method helps is strengthening the structural integrity of a damaged pipe. Depending on the service life desired, a grouting sleeve can be designed for a life of 50 to 100 years. Trenchless rehabilitation methods do not require excavation and can be carried out from a manhole preventing disruption of vehicular and pedestrian traffic.


Trenchlesspedia explains Grouting Sleeve

The steel core of the grouting sleeve has a mechanical locking system that helps to hold the sleeve against the host pipe. An absorbent foam gasket and limit straps surround the core of the sleeve. The limit straps prevent the sleeve from expanding beyond the preset diameter determined based on the host pipe. Before the sleeve is installed, the annular space around the core is fitted with a grout impregnated polyurethane gasket. A closed circuit television (CCTV) guides the sleeve to the spot of repair where air is used to inflate the sleeve till it locks into place. Once the sleeve is locked in, the air plug is withdrawn, completing the installation process. The foaming grout meanwhile keeps expanding till the annular space and cracks in the host pipe are filled.



Grout Sleeves offer a precast panel on panel splicing solution which meets the performance requirements of NZS3101:2006 Amendment 2. Whilst made of Cast SG Iron, Grout Sleeves also had been tested to the performance requirements of NZS3101:2006 Amendment  3. Refer to the documents section for more information.


Unlike conventional lapping utilising drossbach system, Grout Sleeves rely on significantly shorter embedment depths, and therefore reducing onsite hazard caused by long protruding starter bars. Also, Grout Sleeves are generally slimmer than the equivalent drossbach system, therefore minimising reinforcing congestion in precast panels.






Features & Benefits:

  • Eliminates the need for long starter bars protruding from precast elements, that are liable to be damaged or bent during transportation, and therefore provides ease of handling on site.
  • Incorporating Ramset™ Epcon™ C8 XTREM filler, had been tested to meet the new ISO 15835 performance requirement cited in NZS3101:2006 A3.
  • Slim in comparison to the equivalent drossbachs system, thus minimising congestion in precast panels. Smaller and shorter grouted cavity when compared to drossbachs system, therefore less grout and shorter installation time.
