Why Cordless Changes Everything
Built for the places
cords can't reach.
The Elevator Pit Problem — Solved
Elevator pits and other below-grade spaces can have limited access to convenient power. The SG-999 uses a Makita 18V LXT-style battery interface, reducing the need to route powered extension cords to the repair point and simplifying setup in wet or confined work areas.
Cordless Jobsite Setup
Cordless operation reduces cable routing at the repair point. Contractors remain responsible for site-specific electrical, confined-space, PPE, ventilation, and resin-handling requirements.
Battery You Already Carry
SG-999 uses a Makita 18V LXT-style slide battery interface. A 5,000mAh, 90Wh battery is the reference configuration. Battery and charger are not included.
Pair with the Cordless Work Light
Add the 90W, 5,400-lumen cordless LED work light. It uses the same Makita 18V LXT-style battery platform as the SG-999, so one compatible battery and charger platform can support both tools.
Variable Speed Injection
Dial in the pressure for each crack — slow and controlled for hairline cracks, full power for active leaks. Cordless does not mean compromised performance.
PU + Epoxy Compatible
Runs OPU-600 polyurethane for active water leaks and expanding foam seals. Switch to epoxy resin for structural crack repair. One cordless pump handles the full job — from active leak to final structural seal.

SG-999 System FAQ
Cordless crack injection.
The details contractors need.
What battery does the SG-999 cordless injection pump use?
The SG-999 uses a Makita 18V LXT-style slide battery interface. The reference battery is 18V nominal, 21V maximum, 5,000mAh, and 90Wh. Battery and charger are not included.
What is the SG-999 working pressure range?
The variable working pressure range is 1 to 10,000 PSI. Operators should select pressure for the resin, crack, packer, hose, substrate, and repair specification, and monitor the pressure gauge throughout injection.
Can the SG-999 inject polyurethane and epoxy?
Yes. The single-component SG-999 is intended for compatible polyurethane and epoxy injection materials. Always confirm viscosity, pot life, cleaning procedure, and equipment compatibility in the resin manufacturer's technical data and SDS.
Does the cordless work light use the same battery?
Yes. The SG-999 and the 90W, 5,400-lumen LED work light use the same Makita 18V LXT-style battery platform. Both products are sold without a battery unless the product listing states otherwise.
Where is this cordless waterproofing system used?
Typical applications include elevator pits, foundation walls, basements, crawl spaces, tunnels, parking structures, utility spaces, and other concrete repair areas where cord routing is difficult.
What safety precautions apply to high-pressure injection?
Use eye, hand, and protective clothing appropriate for the resin and jobsite. Inspect the hose, coupler, gauge, packers, and connections before use. Follow the resin SDS, equipment instructions, and all site-specific electrical and confined-space requirements.
