Lasers for Concreting — Slab Prep & Screed Heights
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.
Rotating lasers for concreters
Eight rotating laser levels — entry-level horizontal-only through to 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.
Concreting jobs a laser pays for itself on
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.
Form height & pour datum
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.
Slab fall to drain
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.
Screed bed levels
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.
Pad grade for shed slabs
Set a fall across a shed slab so the floor sheds water. Or tilt the laser to match an existing crossfall before you pour.
High/low spot checks during 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.
Datum / RL across a site
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.
The RedBack difference
Anyone can sell a rotating laser. Few back it properly.
Specialist range, not filler
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.
Built to last, built to be repaired
Solid construction, built for the long term. RedBack provides in-house repair and calibration services for all RedBack lasers and most other laser brands.
Real support, real people
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.
Accessories for concreting
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.
