Rotating lasers for concrete work – from setting form heights and checking finished levels to running grade on slab pre-pour. One person, one tripod, the laser plane held all day. The RedBack rotary range covers entry-level through to digital dial-a-grade for compound slab falls.
If you’re after a laser level for concreting, this is the concrete laser level range built for slab work: heights are read with a receiver on a staff, to the millimetre, in any light. The same lasers live on the rotating lasers hub, and the fall-setting models on the grade lasers hub.
Rotating laser levels from entry-level horizontal-only through to the flagship Digital Dial-a-Grade. All IP66 rated for site work, every model pairs with a millimetre receiver on a staff for setting and checking levels.
For most concreting work a basic horizontal laser (BASIC614 or EL614) covers form heights and finished-level checks. If you’re setting a fall on a slab – wet-area drainage, polished-concrete finish requiring fall to a point, ramp grade – step up to a grade laser (EL614S onwards). The DGL1010GM is the flagship: dial in compound falls as a percentage on both axes.
Not sure which model? How to choose breaks it down job by job, spec by spec.
Set up the laser and read the receiver, then the three ways to set a fall on a slab – manual grade with the slope remote, 1-button Auto Grade Match, and digital dial-a-grade.
Where a laser earns its keep on a concreting job – most of these are jobs you’d otherwise check repeatedly with a string line, dumpy, or off-sider.
Set the formwork to a known datum, check every section before the pour, mark pour heights inside the form. One person, one staff, no calling out heights.
Wet-area slabs and polished-concrete pours that fall to a floor waste. Single-grade laser for one-direction fall; dual-grade for slabs falling to a single point from multiple directions.
Run the laser plane over the screed bed during prep – strike the bed to laser height before you set rails. Faster than dot-marking and more consistent across the whole pour area.
Set a fall across a shed slab so the floor sheds water. Or tilt the laser to match an existing crossfall before you pour.
Mid-pour and post-screed, walk the receiver over the surface and the laser plane shows you every high and low spot. Catch problems before the surface sets.
Run a benchmark off the survey peg, set instrument height, every reading on the site comes off that datum. Set-out, formwork, pour heights – one reference plane.
Start with the falls. If the job is flat, any model here holds a level plane all day – the grade models earn their step-up the day a slab has to fall to a point.
A horizontal-only rotating laser covers it – the BASIC614 or EL614. Set the datum, read the receiver on the staff, done.
Single grade. The EL614S sets the fall via slope remote; the EL614GM adds Auto Grade Match – put the receiver where the fall should finish, press one button, the laser tilts itself to match.
Dual grade. The EGL624 and EGL624GM run grade on both axes at once. Most slab work is single grade – step up when the job falls two ways.
The DGL1010GM is the flagship: type a percentage into the keypad or remote and the laser tilts itself to that exact slope – Digital Dial-a-Grade to ±10.000% on both axes.
The full grade range – single, dual and digital – lives on the grade lasers hub, and Auto Grade Match is explained in full on the Grade Tracking Lasers page.

Anyone can sell a rotating laser. Few back it properly.
We sell laser levels and measurement tools – that’s it. Every product on this page is one we’ve used and chosen because it works for concreters, not because it fills a catalogue page.
Solid construction, built for the long term. RedBack provides in-house repair and calibration services for all RedBack lasers and most other laser brands.
Call us and you’ll speak to someone who knows the products. No scripts, no call centre, no runaround – just straight answers from people who’ve worked with these tools for 25 years.
Tripod + staff bundle for setting up the laser, plus a hand-held millimetre receiver for accurate readings during prep and pour. Machine receivers if you’re running the laser onto a skid steer for slab prep too.

If your work is mostly flat slabs, formwork checks and finished-level work, a horizontal-only rotating laser like the BASIC614 or EL614 covers it. If you regularly set falls on slabs (wet areas, polished concrete to a drain, ramp grade) you need a grade laser – start at the EL614S and step up from there.
Single grade for one-direction falls (a slab falling east-to-west to a strip drain, for example). Dual grade for slabs falling to a single floor waste from multiple directions, or compound falls on car parks and hardstands. Most slab work is single grade.
Set the receiver where you want the laser to come to (target slab edge height, or floor-waste depth), press Auto Grade Match, the laser tilts itself to match. Faster than dialling in a grade by trial and error, and removes operator error. See the Grade Tracking Lasers page for the full feature explanation.
Type a percentage into the laser keypad or remote – the laser tilts itself to that exact slope. The DGL1010GM is the only RedBack rotating laser with this feature. Faster than calculating a fall and dialling it in manually.
All RedBack rotating lasers are IP66 – protected against dust ingress and heavy water spray. They handle a wash-down at end of day and won’t fail mid-pour from a passing shower.
Outdoor work like concreting is read with a millimetre receiver, not your eyes – so beam colour doesn’t matter for visibility. Stick with red unless you specifically need a green beam for line-of-sight work indoors as well.
For flat slab work – form heights, screed levels, finished-level checks – the BASIC614 or EL614 covers it. If you set falls on slabs, step up to a grade model: the EL614S for one-direction falls, the EGL624 or EGL624GM for dual grade, and the DGL1010GM if you want compound falls dialled in as a percentage. The comparison above lays it out spec by spec.
Set the laser on a tripod clear of the pour area and let it self-level. Take the receiver on a staff and set your datum off the survey peg or a known height – from there every reading comes off the same plane. Set form heights, strike the screed bed to laser height before you set rails, and mid-pour walk the receiver over the surface to catch high and low spots before the concrete sets. The videos above show the receiver method step by step.
Yes – pad prep is the same method as slab checks: benchmark off your datum and read the staff as you work. Set a fall across the pad so the floor sheds water, or tilt the laser to match an existing crossfall before you pour. Running a skid steer or excavator on slab prep? Pair the laser with a machine receiver like the MR706 so the operator reads level from the seat.

JJay Saunders4 months agoRedback lasers sent the product fast which saw me receive the product in no time. I also received a free upgrade to a lr730 which I was stoked about. The LR730 works a treat for getting heights set out precisely
KKaron Collier4 months agoAs I purchased it for my cousin to use and it has made the job so much easier with alot more jobs to do so it will be getting a workout But very happy with the product
BBradley Barber5 months agoWe just received our first rotating lasor level from RedBack and so far has been great Fast postage , easy ordering and arrived safe and works perfectly
BBearing Logistics6 months agoGreat customer service and open dialogue and follow up. 100% deserved the five stars. Well done
FFranz Franz6 months agoCustomer service was above and beyond. Product has met and beaten expectations. They were sold out of the package deal I wanted but contacted me directly when stock came in to offer it without waiting for it to go online. Had the laser over two weeks now and it's light beam is brighter than my mates DeWalt and the receiver works at a longer distance. Another cool feature is that the batteries have a USB C port on them for charging with USB C cable instead of needing another charger. Was dubious about them being cheaper than others on the market but I honestly can't fault it. Carry box also feels strong and sturdy.
