Dry
Crack Injection.

Structural cracking and concrete defects can occur at any stage of an asset’s lifecycle, from newly constructed infrastructure requiring remediation before handover to ageing structures affected by deterioration, movement and damage. Direct Inject delivers specialist structural crack injection and concrete repair solutions designed to restore structural integrity, durability and long-term performance while minimising disruption to construction and operational activities.

Dry Crack Injection.

Direct Inject provides specialist crack injection services to restore structural integrity and permanently repair dry cracks within reinforced concrete structures. Low-viscosity structural injection resins are introduced into cracks to penetrate internal fissures, bond the concrete and restore continuity across the affected section.

Services
  1. Crack Surveying & Mapping – Identification, measurement and mapping of cracks to record their location, width, orientation and extent. Findings can be recorded against drawings, elevations or client-nominated digital platforms to provide a traceable record through to repair close-out.
  2. Repair System & Methodology Development – Assistance with material selection and repair methodology in accordance with project specifications and engineering requirements. This includes injection pressures, sequencing and preparation of methodologies, ITPs and inspection records.
  3. Low-Pressure Crack Injection – Controlled injection of low-viscosity structural resins using pre-proportioned cartridge systems. Resin is progressively introduced through installed ports at low pressure to achieve penetration and continuity through localised cracking.
  4. Pressure Crack Injection – Pumped injection of structural resins for extensive cracking, deeper sections or higher-volume repairs. Material is delivered through mechanical packers at controlled pressures and flow rates to suit the crack geometry and specified repair requirements.
