Concrete Grouting in Sydney

Specialist Structural, Pressure & Load-Transfer Grouting Solutions

Concrete Engineering Solutions delivers professional, engineer-led concrete grouting in Sydney, servicing commercial, industrial, civil and infrastructure assets. Established in 2020 by experienced industry professionals, we provide value-added engineering solutions that address structural defects, load transfer requirements, service protection and compliance-driven grouting works across New South Wales.

Our grouting services are designed, specified and delivered with a strong focus on structural performance, load correction, durability, compliance and long-term asset integrity.

What is Grouting?

Grouting is not limited to concrete alone.

Grouting is a specialist construction and remediation technique in which engineered cementitious, epoxy, or chemical grouts are injected or placed into concrete, steel, or ground interfaces to address structural, durability, and compliance requirements.

Grouting is commonly carried out when:

  • Structural defects such as cracks, voids or honeycombing are present
  • Post-tension and pre-tension cables require protection and encapsulation
  • Structural steel elements require stabilisation or compliance treatment
  • Ground or substrate conditions compromise structural performance

The objectives of grouting include:

  • Increasing load-bearing capacity and correcting load transfer
  • Stabilising structural elements and foundations
  • Reducing permeability and controlling water ingress
  • Filling voids, cracks and defects
  • Restoring alignment, bearing contact and structural continuity
  • Achieving fire resistance and code compliance in structural elements

When executed correctly, grouting provides a highly effective, engineered alternative to demolition, replacement or major structural modification.

Pressure Grouting & Structural Defect Rectification

Pressure grouting is used where concrete, masonry or rock exhibits cracks, voids or loss of integrity. Grout is injected under controlled pressure to bind fractured zones, restore continuity and improve load transfer.

Common applications include:

  • Foundations and footings
  • Bridge bearings and structural supports
  • Precast panel connections
  • Structural steel baseplates
  • Tunnels, shafts and basements

Structural Steel Column & Base Plate Grouting

Grouting is routinely applied to structural steel columns and base plates, where it plays a critical role in load transfer, stability and code compliance.

Typical applications include:

  • Grouting beneath steel columns for full bearing contact
  • Load correction and levelling of base plates
  • Grouting of holding-down bolt pockets
  • Structural steel column alignment

Fire-Resistance Grouting of Hollow Structural Sections

For fire resistance and code compliance, hollow steel sections, such as SHS and RHS columns, are internally grouted.

This is commonly required where:

  • Steel columns are hollow sections (e.g. SHS 200×200 or RHS)
  • Fire rating requirements must be achieved without external fire protection
  • Compliance with NCC and fire engineering specifications is required

Internal grouting increases thermal mass, delays steel temperature rise, and improves fire resistance, making it a critical compliance solution in many commercial and industrial buildings.

Permeation & Low-Impact Grouting

Permeation grouting strengthens granular soils such as sand without altering soil structure, allowing grout to penetrate voids and improve bearing capacity.

Ideal for:

  • Ground improvement ahead of excavation
  • Basement and tunnel stabilisation
  • Void filling beneath slabs
  • Water control in granular soils

Compaction Grouting & Ground Stabilisation

Compaction grouting involves injecting stiff grout to densify loose or unstable ground and correct settlement-related defects.

Used for:

  • Arresting structural settlement
  • Stabilising loose fill and sandy soils
  • Preventing the collapse of voided ground
  • Supporting existing footings and slabs

Slab Jacking, Load Correction & Void Filling

Where slabs have subsided or lost bearing, grout injection can re-level slabs, correct load distribution and stabilise subgrade conditions without replacement.

Benefits include:

  • Less than half the cost of replacement
  • Minimal disruption to operations
  • Stabilised sub-soil and corrected load paths
  • Fast turnaround with durable structural results

Water Control & Leak Sealing Grouting

We provide targeted grouting solutions to control groundwater ingress while maintaining structural integrity, particularly in underground and retaining structures.

Applications include:

  • Basements and lift pits
  • Tunnels and shafts
  • Retaining walls
  • Underground services and tanks

Post-Tension & Cable Duct Grouting

Post-tension and pre-tension cable systems are grouted to protect cables, prevent corrosion and ensure long-term durability following investigation and verification.

Applications include:

  • Encapsulation of PT ducts
  • Void filling within tendon systems
  • Structural protection and compliance works

Grout Materials We Use

We select grout materials based on structural performance, fire compliance, exposure conditions and design intent, including:

  • Cementitious grouts (standard, high-flow, high-strength)
  • Epoxy and resin-based structural grouts
  • Chemical and specialty grouts for water control
  • Shrinkage-compensated grouts for bearing, alignment and load transfer

All materials are supported by technical data, testing records and project-specific specifications.

Safety, Compliance & Engineering Assurance

Every grouting project is delivered with:

  • Site-specific risk assessments
  • Engineering-led grouting design and methodology
  • Controlled injection and placement monitoring
  • Compliance with Australian Standards and NCC requirements
  • Clear documentation and reporting

We work collaboratively with engineers, builders and asset owners to ensure structural, fire and performance compliance.
