... ABSTRACT: From the early days of simple slurry injection to current sophisticated techniques, grouting has played, and continues to play, an important role in remediation and new construction worldwide. As new grouting technology is developed, and existing technologies are refined, the range...

... ABSTRACT: An investigation aimed at categorising and compiling the technical and environmental aspects of cement and chemical grouts has been carried out. This has resulted in a comprehensive compendium, which includes a systematic strategy proposed to be used by the Swedish National Road...

... of Melbourne. The road collapse was associated with a 4m diameter sewer tunnel being driven through mixed soil conditions under compressed air at a depth to the crown of about 18m . Emergency grouting was conducted from tunnel level and the road surface after the road surface had subsided over 400mm. Over...

... SUMMARY: Injection is defined as the grouting of fluidized materials into voids of the ground or spaces between the ground and adjacent structure, generally through bore holes and under pressure. For many engineers, injection is still considered an art rather than a science. Therefore, its...

... ABSTRACT: Compensation grouting is an effective way to reduce surface settlement induced by construction activities in urban areas. However, the long-term behaviour of the compensated area is still not known very well. Grout injection in clayey soils was performed in the laboratory to measure...

... ABSTRACT: Soft Soil Improvement is an in-situ technique to stabilise soft soil. Recently (1999), a research project at the Soil Mechanics Laboratory of the Ghent University (Department of Civil Engineering) was set up in order to evaluate the influence of the amount and type of grout injected...

... SUMMARY: The type of lining chosen for this plant (now under construction) was non-reinforced concrete with pressure grouting. The tunnel is driven by a Robbin''s mole, Pressure grouting has the following aims: to prestress the lining and the rock mass, to reduce heterogeneity and anisotropy...

.... Therefore it was tentatively decided to provide a positive cut off in the left flank and wherever rock would be met with, it was decided to do grouting to make it waster tight. The treatment for the right bank foundation as to be decided later on. Spillway The Geologist. had suggested the spillway...
