Technical Overview
The Injection Syringe Crack Repair Low Pressure System utilises a simple yet effective mechanism to deliver repair materials into concrete cracks. The syringes are designed to hold and dispense epoxy at a controlled low pressure, ensuring thorough crack filling and effective bonding. This low-pressure approach minimises the risk of over-injection and damage to the surrounding concrete, making it an ideal method for small, delicate repairs.
Filling Capacity: 50 ml/cc
Maximum Pressure: 3.0 kgf/cm2
Maximum Length: 225 mm
Minimum Length: 147 mm
Application Information
-
Materials Required: Injection syringes, epoxy products (e.g., Sikadur 52), anchoring epoxy (e.g., Sika Anchorfix 1), syringe pedestals, rubber bands (optional), hand grinder.
-
Installation Guidelines:
- Clean the surface and remove dust or contamination from the crack.
- Install syringe pedestals (5-6 syringes per meter, 10-20 cm apart depending on crack thickness).
- Secure pedestals with anchoring epoxy, covering the top of the crack. Ensure the product has cured before injection.
- Draw mixed epoxy into the syringe (30cc) and mount the syringe into the pedestal.
- Inject epoxy via the pedestal until flow from the adjacent pedestal or until epoxy stops flowing.
- Attach rubber bands to apply constant pressure if required.
- After epoxy hardens, remove syringes and pedestals and restore surface finish with a hand grinder.
-
Trade-Specific Tips: Ensure proper surface cleaning and pedestal installation for effective crack sealing. Monitor epoxy flow during injection to prevent overfilling.
Limitations
- Primarily designed for small concrete cracks.
- Effectiveness depends on the chosen epoxy product and proper application technique.
Safety precautions when using Injection Syringe Crack Repair Low Pressure System:
-
Personal Protective Equipment: Wear appropriate gloves, safety glasses, and respiratory protection if necessary, in accordance with the safety data sheets of the epoxy products being used.
-
Epoxy Handling: Follow safety instructions provided by the epoxy product manufacturer. Avoid skin and eye contact.
-
Surface Preparation: Ensure proper cleaning and preparation of the crack area.
