Water Leakage Injection Instant Sealing for Lift Pits

Permanent Water Leakage Injection for Lift Pits, Basements, Joints & Concrete Cracks – Works Under Live Hydrostatic Pressure

 

The Live Leakage Injection Waterproofing System is a specialized solution for stopping active water leaks in concrete structures. Using polyurethane (PU) or acrylic-based resins, this system injects chemical grouts directly into cracks, joints, or honeycombs while water is actively flowing.

Known as “live injection waterproofing”, it provides a rapid, durable, and flexible solution without waiting for surfaces to dry or removing finishes.

Why Choose Water Leakage Injection for Lift Pits & Structural Waterproofing in Dubai?

OFIXO's water leakage injection system is the most reliable solution for stopping active water leaks in lift pits, basements, parking decks, expansion joints, and concrete slabs across Dubai. Using high-pressure polyurethane (PU) injection, this system penetrates hairline cracks and voids to form an instant, flexible watertight seal - even under live hydrostatic pressure.

How the System Works 

Injection of reactive resin (PU or acrylic) into cracks, joints, or voids 

Allows slight structural movement without reopening the crack 

Forms a watertight, elastic plug that seals cracks completely 

Chemical reaction with water causes the resin to foam, expand, or gel 

Seamless, internal waterproofing without damaging finishes 

Applications of Water Leakage Injection in Dubai

Basement walls and foundations 

Underground tunnels and parking decks 

Water tanks and swimming pools 

Retaining walls and podium slabs 

Expansion and construction joints 

Lift pits, sumps, and concrete roofs 

Step-by-Step Application Process 

Identify Leakage Points 

  • Inspect surfaces for visible cracks or seepage 
  • Mark areas for injection port installation 
  •  Surface Preparation 

  • Clean the leaking area, removing paint, laitance, and debris  
  • Drill injection holes at 45° angles, spaced 150–300 mm apart 
  •  Install Injection Packers 

  • Insert mechanical packers (nipple-type or button-head) .
  • Tighten securely to withstand injection pressure 
  •  Injection Process 

  • Use manual or electric injection pump . 
  • Inject PU foam or resin from the lowest point upward  
  • Close packers once resin reaches adjacent points, ensuring full penetration 
  • Reaction and Expansion 

  • Resin reacts with water, expanding to seal cracks internally 
  • Resin reacts with water, expanding to seal cracks internally  Reaction time: typically 30 seconds to 5 minutes 
  • Post-Injection Sealing 

  • Remove packers after curing (2–4 hours) 
  • Seal drilled holes with polymer-modified mortar or epoxy putty  
  • Optional second injection for structural cracks 
  •  Testing & Inspection 

  • Perform water tests to confirm all leaks are sealed  
  • Repeat injections locally if minor seepage remains
  • Worker preparing wall substrate for membrane waterproofing system installation
    Crack injection waterproofing applied to a damaged concrete wall.

    Frequently Asked Questions(FAQs)

    Water leakage injection waterproofing is a method of stopping active water leaks by injecting polyurethane (PU) or cement-based grout into cracks, joints, and voids under pressure. The injected material expands to fill the cavity and forms a permanent watertight seal- even in wet or submerged conditions. It is widely used in Dubai for basements, lift pits, tunnels, and concrete structures.
    Yes. Water leakage injection is the most effective solution for lift pit waterproofing in Dubai. Lift pits frequently suffer from groundwater seepage, construction joint failures, and honeycomb concrete defects. OFIXO’s high-pressure PU injection system stops these leaks from inside the shaft – without dewatering, excavation, or halting lift operations.

    If you notice standing water at the base of the lift shaft, active seepage through construction joints, efflorescence (white salt deposits) on walls, or a musty smell inside the pit, water leakage injection is likely required. Early injection treatment prevents damage to lift machinery, electrical systems, and the structural slab. Contact OFIXO for a free on-site inspection across Dubai.

    Unlike traditional methods that require the surface to be dry or the removal of finishes, live injection works immediately while water is actively leaking.

    The system primarily uses highly reactive Polyurethane (PU) foam or Acrylic-based resins.

    Yes, the system is designed to provide a durable and permanent, and flexible barrier.

    Typical applications include basement walls and foundations, underground tunnels, parking decks, water tanks, and more.

    The reaction and expansion time is very rapid, typically ranging from 30 seconds to 5 minutes, providing immediate sealing of the crack.

    An injection packer provides a secure, high-pressure connection point for the injection pump to deliver the resin into the structure.

    No, a major advantage of this system is that it involves minimal structural damage.

    After the initial reaction, the packers are typically removed after 2-4 hours of curing. 

    Yes, one of the primary advantages is its ability to work effectively under high hydrostatic pressure.
