Hi vin, I have done it like this in the past and worked well. I just wondered if the same crack if in the manhole, set on a pin for centre off manhole with the block set on invert. Thanks for your replyHi .
You don’t need to put it in the channel at all .
You can put it on the ground above if you like . Just use a wee boat level to level up your block on a bit of sand and have the block pointing in the direction you want to go . Put the laser on top of it and type in your gradient . Then dig down in front of it to the depth you require . When your dig depth is perfect put a vertical stick on the bottom of the trench and mark the point the laser hits it . This is now your traveller . Carry on digging and when your mark in the stick lines up with your laser then your at the right height . If you want 50mm bedding put a mark 50mm lower on the stick and then use it to regulate your bedding height .
Have you bought one ?
