Fast Concrete Leveling Machine

Fast Concrete Leveling Machine with batteries, laser receivers ×2, battery charger (AGM 24V 20A). The rotating laser level is NOT included — purchase any red-beam rotary laser separately. To operate the device, a measuring tape is also required.

The Fast machine is motorized (powered wheel, 145 Nm of rotational torque) and uses a vibrating bar (750 N / ~76 kg vibration force) combined with a plow blade. The working element rests on the poured concrete, so the unevenness of the base surface does not affect accuracy. It is the most versatile machine — suitable for both sand/base leveling and concrete pouring, and works on S1–S4 concrete, uneven bases, mesh, underfloor heating pipes, and other materials. It is also the most compact: it fits through a 45 cm opening and can be quickly disassembled for transport.

S1, S2, S3, and S4. It is not suitable for S5 or very fluid S4 concrete. For more fluid concrete, the Precise Concrete Leveling Machine is recommended.

Maximum pour thickness is 30cm.

Yes — this is one of the machine’s strengths. It is excellent for leveling sand bases, crushed rock (0–4 mm and 0–8 mm fractions work well; stones larger than 12 mm may cause dragging). The powered wheel provides strong traction for heavy sand pulling. Multiple passes can be made to reach the desired height level.

Yes. The Fast machine was specifically designed for this. Since the working element rests on the poured concrete (not the subbase), bumps from underfloor heating pipes or mesh have no effect on accuracy. It is a better choice than the Precise machine for highly uneven base surfaces.

Fast is better for: thicker concrete, uneven bases (underfloor heating, mesh), sand and material leveling, compact transport through narrow openings, multiple passes. Precise is better for: more fluid concrete (S3–S5), very large flat areas, fiber-reinforced concrete at high speed, maximum precision when the base is flat. Both achieve ±1 mm accuracy.

Up to 350 m²/hour, making it the fastest of the three Concrete Wolf machines.

68 kg including batteries.

1180 mm vibrating bar width.

Two × 12V 38Ah AGM batteries (operating voltage 24V). Batteries are INCLUDED with the machine, together with the charger (AGM 24V 20A). Working time at maximum load is approximately 2 hours. Charging: 4 hours (normal 10A) or 2 hours (fast 20A).

Yes. In transport mode, the machine fits through a 45 cm wide opening. Assembly takes only 30 seconds.

The vibrating bar rests on the concrete being leveled. The plow pulls excess concrete to the correct height while the vibrating bar levels the surface. The laser receivers continuously send height data to the controller time they receive the laser beam, and the blade is automatically adjusted. For more fluid concretes it is recommended to check with a laser receiver periodically.

Power button: press once to activate (the logo and battery symbol on laser receivers light up, machine in neutral); press again to deactivate (working body lowers, machine goes to sleep). Three-stripe button: first press = forward/transport mode (max 80 cm/s, working body tilts for easy front lift); second press = neutral; third press = reverse/working mode (max 30 cm/s, plow starts searching for lasers and height arrows light up. Speed control (thumb): in working mode, starts vibration and increases reverse speed.

Both red arrows flashing (no direction): laser not detected for >0.6 sec. Red arrow DOWN: plow is above the vibrating screed, moving down. Red arrow UP: plow is below the vibrating screed, moving up. Green ‘0’ light: plow and vibrating screed are at the same level. Three stacked squares: battery level (all green = 83–100%; bottom two green = 50–83%; yellow = 33–50%; red = 16–33%; flashing red = <16%).

Yes. The Fast machine is well suited for preparing base layers for sports surfaces such as padel courts. For clay tennis courts (soft, granular surface with sand/gravel underneath), the Fast machine is also recommended. It handles various materials and is not limited to concrete.

Before use: spray with a biodegradable oily substance. After use: wash with running water and a brush.

Height control is fully automatic. All Concrete Wolf machines use servo motors that adjust the blade/working element up or down, guided by rotary laser receivers. The operator only needs to pull or steer the machine — the automation does the rest automatically. This is far faster than hydraulic systems (which respond ~4 times per second).

The machines include laser receivers (×2) but NOT a rotating laser. You must purchase any red-beam rotary laser separately — 600 rpm is recommended. Compatible brands include Leica, Hilti, Bosch, Spectra, Topcon, Trimble, Stabila, NEDO, NIVEL, and others. Cross-line lasers are NOT compatible. The laser rotation speed must be at least 300 rpm.

All machines achieve ±1 mm leveling accuracy. The laser receivers themselves are accurate to ±0.5 mm. In practice, ±1 mm is achievable with a consistent and careful operator.

Yes. Slopes can be achieved in two ways: (1) tilt the rotating laser beam to the desired angle — the machine will follow the slope precisely; or (2) adjust the laser receivers on the machine to different heights on each side to create a cross-slope. Any gradient that can be set on a red-beam rotary laser (including grading lasers) is supported.

Yes. Because the Vibration Laser Screed and Fast Concrete Leveling Machine rest on the poured concrete surface, what lies beneath (rebar, mesh, fiber reinforcement) has no effect on operation. The Precise Concrete Leveling Machine can also work over rebar/mesh, but must operate at approximately half speed. At full speed, the Precise machine works well with fiber-reinforced concrete.

No prior experience or training is required. All machines are designed to be intuitive — the operator only needs to pull (Vibration Laser Screed) or steer (Fast, Precise). No one has contacted Concrete Wolf with usage difficulties. The machine is pre-calibrated at the factory; additional automatic calibration runs at every startup.

Only calibration that is needed is setting the laser recievers at the correct height.

1. Set up the rotating red laser at a height of 30–100 cm above the concrete surface to be leveled. 2. Measure the laser beam height from the finished concrete surface (using a tape measure and a standard laser receiver/grade rod). 3. Move the ‘0’ marks of the machine’s laser receivers to the measured height from the lower edge of the blade/plow (Vibration Laser Screed should be switched OFF during the procedure, Precise Concrete Leveling Machine and Fast Concrete Leveling Machine can be ON or OFF). The machine is then ready — just switch on and begin working.

All machines carry a 1-year manufacturer’s warranty. If a defect occurs, Concrete Wolf will repair or replace the device. Spare parts are always kept in stock and can be shipped quickly. For simpler issues, parts can also be sent to you to be replaced on site.

Concrete Wolf sells to any country where there are no economic restrictions, either directly or through dealers.

In normal situations, an immersion vibrator (vibrating poker/needle) is not needed. If there is a risk of trapped air in the concrete structure (e.g., thick slabs with dense rebar), you may run a vibrating poker before surface leveling. For the surface smoothing work the machines are designed for, an immersion vibrator is not required.

The concrete should be mixed as usual — the slump class should be suitable for the machine, otherwise there are no special mixing requirements for Concrete Wolf machines.

If the operator works carefully and consistently, ±1 mm finished floor level (FFL) tolerance is achievable with all machines. As the machines are manufactured in Europe, FF/FL numbers (US system) are not currently recorded, but results are expected to be excellent.

Yes. Concrete Wolf machines were specifically developed for high-rise buildings, basements, apartments, and similar complex environments. The Vibration Laser Screed models are the easiest to transport to elevated locations. The Fast and Precise machines are heavier but still manageable — the Fast machine can be disassembled into 2 parts for transport in 30 seconds.

The Precise Concrete Leveling Machine can handle S5 (very fluid) concrete; minimum pour thickness is 2 cm. The Vibration Laser Screed is not suitable for S5 and not recommended for very fluid S4 concrete. The Fast Concrete Leveling Machine is also not suitable for S5 or very fluid S4.

Vibration Laser Screed: lightweight, manually pulled, suitable for S2–S4, any pour thickness, any base surface condition. Best for tight areas. Fast Concrete Leveling Machine: motorized wheel, suitable for S1–S4 (not S5), pour thickness 0–300 mm. Ideal for uneven bases, sand leveling, underfloor heating pipes. Precise Concrete Leveling Machine: motorized, auger based operation, suitable for S3–S5, pour thickness 20–200 mm above support surface. Best for large areas, fiber-reinforced concrete, very fluid concrete. Not ideal for very uneven bases.

European concrete workability is classified by slump: S1 = 10–50 mm, S2 = 50–100 mm, S3 = 100–160 mm, S4 = 160–210 mm, S5 = ≥220 mm. S1 is the least fluid; S5 is the most fluid.
