Hydro-Demolition.

Removing concrete in structurally sensitive, confined, or noise-restricted environments presents serious challenges. Traditional methods can generate excessive vibration, risk structural damage, and expose workers to harmful silica dust. High-pressure water jetting offers a safe and environmentally friendly alternative.

CONCRETE REMOVAL.

Direct Inject’s hydro-demolition services offer a safer, quieter, and more precise alternative, minimizing disruption while preserving reinforcement, waterproofing, and surrounding structures. Ideal for full-depth removals, pile and diaphragm wall trimming, or controlled re-profiling, our high-pressure water jetting technology ensures compliance with health, safety, and noise regulations, making it perfect for out-of-hours or urban work.

Typical Applications
  1. Selective Concrete Removal: Precision removal of excess, deteriorated or defective concrete while preserving reinforcement, underlying structures and waterproofing systems.
  2. Full-Depth Concrete Removal: Complete removal of concrete slabs, bridge decks, or structural components.
  3. Pile and D-wall trimming

SURFACE PREPERATION.

Preparing and maintaining concrete surfaces can be challenging, labor-intensive, and often hazardous when using traditional methods like mechanical grinding wich will generate dust and vibration. This non-destructive, dust-free process enhances worker safety, minimizes environmental impact, and ensures a superior surface for repairs, coatings, or overlays, making it the ideal choice for complex or sensitive applications.

Typical Applications
  1. Concrete Profiling: Stripping off surface layers to expose sound concrete for repairs or overlays.
  2. Surface prep for re-sheeting of public roads.

DETAILED EXCAVATION & PROFILE CONTROL.

DIrect Inject have retro fitted a high pressure water jetting lance to a robotic Brokk 200 which can be effectively used for detailed excavation in rock by utilizing the ultra-high-pressure water jett to precisely erode material without excessive vibration or structural damage. This makes this machine ideal for applications where traditional rock-breaking methods in high strength material—such as hydraulic hammers or blasting—are too aggressive, imprecise, or pose safety and environmental risks.

Key Benefits of Using Hydro-Demolition for Rock Excavation and profile control include.
  • Precision Cutting: The high-pressure water stream can be easily controlled to selectively remove rock, making it ideal for shaping structures, enlarging tunnels, or re-profiling shotcrete linings.
  • Reduced Vibration: Unlike mechanical breakers, hydro-demolition minimizes the risk of damaging adjacent structures, making it suitable for work near sensitive infrastructure and existing assets.
  • No Dust or Airborne Silica: The water-based process eliminates the health hazards of silica dust exposure, improving safety and regulatory compliance.
  • Adaptability in Confined Spaces: Robotic units can be remotely operated in tight or hazardous environments, reducing the need for manual labor in high-risk areas.
  • Effective in Hard or Variable Rock Types: High-pressure water can penetrate fractures and weaken hard rock formations, making excavation more controlled and efficient.

 

This technology is particularly useful for tunneling applications, controlled rock shaping, and excavation in urban or environmentally sensitive areas, where traditional methods may be too disruptive, unsafe, or impractical
