The use of laser level for large works has increased notably in the last two decades with respect to traditional leveling instruments, due to the fact that their cost – each day more competitive – and their simplicity of use allow to maximize the efficiency of leveling and squaring tasks, with which After the initial investment, it is possible to greatly improve work times.
But what are the most suitable models for major works and reforms? Beyond each use, and the selection made of the instrument, whether traditional or with greater technology, in Of Machines and Tools We believe it is necessary to provide a guide for the correct choice of this measuring instrument.
The most suitable large-site laser level
What factors must be taken into account when choosing a laser level for large works? It is important to ask this question before going to the store. tools, since the choice depends on several points.
First is the versatility of the instrument: the most suitable are those that allow leveling, squaring, centering and projecting a point or a line along the internal or external walls of a building. This must be the fundamental factor; It will be useless, once on site, to have to carry three or more instruments just because each one is specialized in a single function. In any case, if it is necessary to use a special level, it will be done only when necessary.
A laser level for large works versatile is anyone that offers enveloping cross-line projection —that, in a room, projects the lines onto the floor, ceiling, and the three surrounding walls— and is self-leveling. Cross lines allow horizontal leveling, vertical squaring and easily finding the geometric center of any wall. With the use of a tape measure or a laser distance meter, we can also center any element, or equidistant a series of them.
A further advantageous feature is the ability to pivot on its own axis to allow oblique lines to be projected; This is particularly important if you want to build a staircase, for example.
Range in meters
The second most important factor is the range in meters of the laser lines. Normally the buildings have a surface area of twenty meters by fifteen; It is recommended that, at least, our device has a range of ten meters. Placed in the center of the construction, with that scope we can cover all the walls without problems.
A versatile and powerful device would be of no use if your battery dies in no time. For that it is necessary to search laser levels with a battery capable of keeping the equipment on for at least ten hours without the need to recharge it.
A laser level for large works it must be precise enough that the maximum leveling error over a linear distance of twenty meters is less than one centimeter. This equates to a maximum slope of 0.5 ‰.
Finally, it is also important to take into account the weight and maneuverability of the instrument. It is important that it be small, robust and light, so that it can be transported comfortably on and off the construction site.
A good laser level for large works it must weigh no more than half a kilogram, and it must occupy a volume no greater than 10 cm³ (not counting accessories such as a tripod or remote control, if any).
A review of the necessary capabilities in a good laser level for large works
- Is it versatile enough to allow tasks such as leveling, squaring, centering, projecting points and lines horizontally and vertically? Does it allow to project oblique lines?
- Does it have a minimum range of ten meters in normal visibility conditions?
- Can the battery keep the equipment on for at least ten hours? Is the recharge fast?
- Is the leveling error less than 1 ‰?
- Is it small and compact enough to be conveniently transported both on the construction site and outside (in a car)?
Think about the possible works you are going to do: suppose you want to install a new series of openings in a wall; one door and two windows, correctly squared, leveled and centered. The cross line laser level allows you to do it with agility. You just have to find the geometric center of the wall, center the door there and place the two windows at a height such that the upper edges coincide with that of the door (if that is something aesthetic and functional). Starting from the center point, you only need to use a meter to measure the necessary distance to either side, and center the rectangle of each window on that measurement.
Another possible work is the construction of a staircase inside, to reach the first floor. Simply draw the necessary lines using the oblique projection function of the laser level; You can also use them to quickly calculate the required slope, and the height of each step.
Do you need to tack a discharge pipe for rainwater, from the terrace to the garden? Just place the laser level on your tripod and project a centered vertical line on the wall. The line will be perfectly plumb.
Do you want to build a perimeter wall and need to drive the rope stakes to raise the brick wall? You only need to place the stakes, project an enveloping line and mark the desired height on each of them, and then pass through there the string that will indicate the necessary level of bricks.
