A low-pressure syringe system for small concrete cracks. Glue the syringes along the crack, fill them with epoxy, and the spring-loaded syringes hold steady pressure on their own, drawing resin deep into the crack over time without the force that would widen it.
The gentle method for car parks, balconies, walls, and pools, where the crack is real but the repair does not need a pump.
Frequently asked questions
What type of cracks does this syringe system repair?
This system is designed for small concrete cracks in structural elements. It provides controlled epoxy delivery to ensure thorough filling without excessive pressure.
What is the maximum pressure for epoxy injection?
The syringe is rated for a maximum injection pressure of 3.0 kgf/cm². This low-pressure delivery helps to prevent hydraulic fracturing of the concrete.
What other materials are required for crack repair?
You will need an epoxy product such as Sikadur 52, an anchoring epoxy like Sika Anchorfix 1, syringe pedestals, and a hand grinder for surface preparation and finish.
How are the syringe pedestals installed for injection?
Install pedestals 10-20 cm apart, typically 5-6 per linear metre of crack, depending on crack thickness. Secure them with anchoring epoxy and seal the crack surface between them.
Substrate guide
Proper surface preparation is essential for effective crack repair and bond strength of the epoxy system.
Concrete
Surface prep: Grind the crack area clean and free from dust, loose material, and contaminants. Ensure the crack is dry before proceeding.
Primer: Not required for the syringe itself. The specific epoxy product chosen for injection may require or benefit from a primer as per its manufacturer's instructions.
