Grouting Services possess a wide range of specialist grouting plant that is able to operate at a range of pressures up to 1000psi, and, are proven with a variety of specialist cementitous grout mix designs, including sand : cement, cement : bentonite and plasticers. Water reducing agents and plasticers are regularly used within our day-to-day grouting operations to improve workability and reduce bleed.

A range of proven cementitous grouting techniques are available in-house including:

• Ground improvement and soil stabilization grouting for enhancement of the mechanical properties of the soil and remediate problems associated with subsidence
• Under-slab grouting and re-levelling
• Bentonite/cement grouting to impregnate open soil
• Fissured rock grouting typically performed in downward phases
• Void filling to eliminate collapses, sink holes or depressions associated with deformation of the ground surface
• Tube-a-manchette grouting to improve uplift resistance of bridge substructures and
  foundations (the tube-a-manchette is first sealed in place followed by grouting via a double parker located over discretely positioned valves within the tube-a-manchette)
• High-pressure (5MPa) post-grouting in weak soils to improve the bond capacity of ground anchors and soil nails
• Structural steel and foundation grouting
• Precast concrete grouting for panels, barriers and columns and associated connections
