Grouting

What is Bridge Grouting?

Bridge Grouting is a methodology used to remedially improve the structural integrity of a bridge or similar structure. The subject bridge would generally be older in nature whose structural integrity has been compromised by the increase in traffic footfall that the bridge would not have been originally designed for.

Brief Methodology:
  • Typically bridge grouting involves the drilling of boreholes to a certain level depending on the structure and its remedial requirements.
  • These boreholes are then injected with a cementitious suspension grout which fills the boreholes and any voids. This produces additional tension within the bridge rendering it more structurally sound.
  • Primary boreholes are drilled using a rotary percussive drill and purpose built flush jointed hollow stem drill rods which double up as grout injection lances.
  • Grout is typically colloidally mixed in a high speed, high shear mixer/pump with a thixotropic additive to curtail migration of grouts in sub soils.
