The Laser Screed is used in large area concrete construction, such as the modern industrial workshop, the large market, storage, airport, the plaza, and so on. The Laser Screed can satisfy the construction requirements of large area and high planeness and levelness.
1. Screed assembly is hydraulic controlled. Integrated with laser system and computer control system, the machine will self-level and finish the screeding work with high efficiency.
2. The Laser transmitter which measures the elevation is independent located, so there is no worry about the accumulative error. Compared with the traditional way, the construction joints will be greatly reduced, so the maintenance cost and slab use will be down greatly. For the complex floor which has high requirement for drainage, the 3-D floor processing system can be used.

A powertrowel is used to create a level, smooth finish on a large, flat area of concrete, such as an interior floor, or a poured patio slab for a deck. They use single or multiple blades that rotate in a safety cage. They measure from 24 to 48 inches long and come in three types: floating, finish, and combined. You can use a pushable concrete powertrowel or riding model based on the size of your job. Follow the steps before for the proper procedures so you can use this tool to the best of your ability.
Step 1 - Choose a PowerTrowel
To level a small area of under 1000 square feet, choose a pushable powertrowel with 24 to 36 inch trowel blades. Get both float and finish trowel blades, or select a combined blade, to smooth the concrete in one series of passes.
For large areas over 1000 square feet, a riding powertrowel will help you finish quickly before the concrete sets too firmly. Use blades that measure 36 to 48 inches in size. For corners, switch to a 24 inch blade. Choose separate float and finish blades, or a combination trowel blade.
Step 2 - Test the Concrete Before Troweling
Have the concrete poured a few hours before using the powertrowel. Make sure it is firm enough to support you and the powertrowel by doing a footprint test; step onto the slab and measure the imprint depth. If the imprint is 1/8 of an inch deep or less, the concrete is ready for troweling.
Step 3 - Float the Concrete to Remove "Hills and Valleys"
Use the trowel with float blades or combined blades to level the concrete on your first pass. Floating reduces bumps (hills) and fills in the hollows (valleys).
Run the machine at 3/4 speed with the blades flat to keep the weight of the machine evenly distributed and avoids digging into the concrete. This speed of rotation will also prevent splatters of still-damp concrete being thrown forward into the machine's path. Overlap each pass by 1/2 the length of the trowel blades as you traverse the poured plate.
When you finish floating the entire slab once, turn the powertrowel at 90 degrees to your first rows. This crossover floating technique enables you to finish missed spots.
Step 4 - Finish the Concrete to Seal, Close, and Polish
Change to finish blades or continue with the combined trowel blades to finish the surface, sealing the porous material. Run the powertrowel at its top speed this time with the blades fully pitched downward onto the concrete. This will give the highest pressure on the slab. Make as many passes at right angles as desired to get a matte, light gloss or gleaming finish.
Safety Tips
Wear safety goggles, ear protection, and boots with a steel toe and soleplate while operating any type of powertrowel. Always use heavy leather work gloves and turn off the powertrowel before clearing or changing blades.
When operating the powertrowel, reduce speed when turning corners to avoid tipping the machine. Also, cordon off the area, for safety and to prevent marring the concrete.
These high-tech screeds are ideal for striking off commercial and industrial concrete floors that must meet stringent F-number tolerances (see Understanding F-Number Requirements for Commercial and Industrial Floors). The screed head comes in various widths, ranging from 12 to 20 feet, and is mounted on a self-propelled four-wheel drive machine with a telescoping boom that extends up to 20 feet across the slab. The screed head is equipped with a plow, auger and vibrator to disperse the fresh concrete, remove excess material to finished grade, and smooth the surface. Laser receivers mounted at each end of the screed head receive a signal from a transmitter to automatically strike off the floor to specified flatness levels. Top manufacturers of laser screeds include Somero Enterprises, Ligchine International and Allen Engineering
For large concrete pours measuring over 6,000 square feet, a riding power trowel is practically a necessity for finishing the concrete before it sets. In addition to boosting productivity, ride-on trowels will also produce flatter finishes due to their weight. These machines come with twin blades ranging in diameter from 36 to 60 inches. You can also choose from overlapping and non-overlapping machines. Overlapping models have intersecting blades that are well-suited for trowel finishing, but you can’t use them for floating. Non-overlapping machines have a space between the rotors so you can mount float pans on them for initial finishing and switch over to trowel blades for final finishing. Smaller twin 36-inch-diameter ride-on trowels are easier to maneuver and provide adequate coverage for medium-sized floor slabs. For large floors requiring super-flat finishes, twin 60-inch-diameter ride-on machines are the best choice. In addition to size, look at the machine’s weight-to-power ratio, drive system (hydrostatic or mechanical), ease of pitch control, and blade accessibility.
Walk-behind trowels are ideal for finishing driveways and small to mid-sized commercial or warehouse floors. In addition to being nearly effortless to operate, they give concrete surfaces a smooth, hard, durable finish. When buying a walk-behind trowel, the model you choose will primarily depend on how much surface area you need to cover. Walk-behind trowels come with blade diameters ranging from 24 to 48 inches. Smaller units are well-suited for finishing surface areas less than 1,000 square feet. They will also fit more easily through doorways and work around obstacles. Larger models are better suited for medium to large floors requiring greater speed and efficiency. With most units you can choose separate blades for floating and finishing or a combination blade that can perform both functions.
Most walk-behind trowels come in gas or electric-powered versions, allowing you to choose a machine that will work with the available power supply. Other features to look for include easy access to trowel blades, quick blade pitch adjustment, height-adjustable handles, ergonomic throttle control and optimal balance for smoother finishing.
A power trowel (also known as a "power float", "helicopter" or "trowel machine" or "whirlybird") is a piece of light construction equipment used by construction companies and contractors, to apply a smooth finish to concrete slabs.
