This low-pressure injection syringe is an accessory for feeding suitable epoxy injection resin into fine concrete cracks. It is used as part of an appropriate low-pressure repair system rather than a powered pumping setup.
The repair method, resin viscosity, preparation and port attachment must be suitable for the crack. Check system requirements before ordering; results depend on concrete condition and the selected resin.
Low-pressure spring-loaded syringe system for injecting epoxy into small concrete cracks.
Maintains gentle pressure over time so low-viscosity resin can penetrate a tight crack without the force of a pump.
Useful where a crack is suitable for low-pressure epoxy injection rather than packer pumping.
Prepare and surface-seal the crack, then bond syringe ports at the spacing specified by the repair method.
Fill the syringes with the compatible low-viscosity resin and allow the spring pressure to feed the crack.
Top up or advance through the ports according to the resin system, then leave the repair undisturbed for the specified cure.
For small cracks suitable for low-pressure injection.
Active water leaks, large voids, wide cracks or repairs requiring controlled pump pressure need a different injection method and resin.
Crack suitability, port spacing, surface seal and cure schedule must follow the selected repair-resin system.
