INJEXA SWDM 2500 Epoxy Crack Injection Machine
or 4 interest-free payments with
The dual-feed injection machine specified for ACTFLEX ER300. It meters and mixes Part A and Part B at the nozzle, so nothing is premixed.
The INJEXA SWDM 2500 is a dual-feed two-component injection machine. Part A resin and Part B hardener go into their own containers and the machine mixes them at the nozzle through a static mixer. It is the machine the ACTFLEX ER300 Technical Data Sheet names for structural epoxy crack injection.
What it's for
- Injecting ACTFLEX ER300 structural epoxy into 0.1 to 1.0 mm cracks in reinforced concrete
Why waterproofers buy it
- Dual feed: no premixing, no decanting the two parts together
- Meters ER300 at its 2:1 by weight ratio automatically
- Named in the ER300 TDS, so the repair stays inside the Forspec system for warranty eligibility
Specs
Dual-feed two-component injection machine with mechanical packers, high-pressure hose and static mixing nozzle. Flush with epoxy thinner after use to prevent hardened material blocking the lines.
Spec sheet: ACTFLEX ER300 TDS.
Dual feed - meters and mixes Part A and Part B at the nozzle through a static mixer, so nothing is premixed

Key applications
- Structural crack injection of fine to medium cracks in reinforced concrete with ACTFLEX ER300
- Restoration of load-bearing capacity where cracks compromise the structural performance of slabs, beams and columns
- External steel plate bonding for structural strengthening
- Floor lifting and delamination repair, re-bonding lifted concrete surfaces and detached floor toppings
- Bridges, tunnels and civil infrastructure in high-load, high-stress environments
- Industrial flooring and warehouse slabs, injecting cracks in high-traffic areas
- Precast, tilt-up and in-situ concrete elements requiring structural crack rectification
Surface suitability
- Concrete (clean, sound and free from contaminants; dry or at most slightly damp, never active running water)
- Reinforced concrete slabs, beams and columns
- Precast, tilt-up and in-situ concrete elements
Injection work delivers material under pressure. Never point a pressurised hose or packer fitting at any person, depressurise before disconnecting, and be aware that high-pressure injection injury is a surgical emergency requiring immediate hospital treatment even where the entry wound appears trivial. Do not exceed 2.5 MPa (25 bar) injection pressure, because excessive pressure widens the crack, causes blowouts and can damage the element. Do not premix Part A and Part B: the machine meters and mixes at the nozzle. Confirm the static mixing nozzle is clean and correctly fitted before starting, because a partially blocked nozzle delivers unmixed or off-ratio resin. Have flushing solvent and a spare mixing nozzle on hand before commencing, because the machine cannot be left standing with resin in the lines. Flush both the Part A and Part B lines immediately after use, and clean the static mixing nozzle, hoses and packer fittings before the resin cures. Hardened epoxy will permanently block the injection machine, hoses and mixing nozzle and cannot be removed. Use only in a well-ventilated area with the personal protective equipment specified in the Safety Data Sheet.

Frequently asked questions
-
What is the INJEXA SWDM 2500 used for?
CompatibilityThe INJEXA SWDM 2500 is a heavy-duty electric epoxy crack injection machine designed for two-component epoxy resin injection (Crack Pro 1200PS, ProBond 1100PS, ER300) into structural cracks under controlled pressure with automatic A:B ratio mixing.
-
What's the advantage over manual pumps?
PerformanceElectric operation delivers consistent flow rate and pressure without operator fatigue, automatic ratio mixing ensures correct A:B blend (critical for epoxy cure), and the higher output makes the SWDM 2500 viable for large structural projects.
-
How is it set up?
InstallationFill the A and B resin reservoirs, connect the static mixer outlet to the injection wand and packer, set the pressure and flow rate, then inject sequentially through each packer until refusal. Refer to the operator manual for full setup procedure.
-
Which resins work with this machine?
CompatibilityDesigned for the Forspec two-component epoxy injection resins including Crack Pro 1200PS, ProBond 1100PS, and ER300. Single-component polyurethane resins use the manual SWM 1300/1500 pumps instead.
-
Are there electrical/safety requirements?
ComplianceRequires standard 240V single-phase power (Australia/NZ). Always clean and flush the mixing system between jobs - cured epoxy in the static mixer will require replacement of the mixer head. Follow lockout/tagout procedures during maintenance.
