One of the questions we always here is how do we accurately establish a set level for when we are carrying out building work? This may also be determined as a ‘datum’, which will be the set level that we will take all of our measurements from in order to set out levels for other part of the build.
Our preferred method to do this is by using a rotating laser level and a staff whereby we can establish a datum to work from that works very well for us. Still know of some builders that even just use a long spirit level and transfer levels that way but it won’t really have the same accuracy and relies on an element of guesswork to get it right.
For most of our building jobs in Liverpool we will use the laser level method but I can remember on a couple of jobs a few years back where conditions called for it, we had to use the ancient water level method that many of you may not have even heard of.
This is a method that is so ancient and was even used years and years back by the Egyptians…
I could go into massive detail about this but instead I’ve written an article about using a water level and you can view it here. Have a read and let me know your thoughts. I’d love to hear them
