I am up to building timber pile foundations for a tiny house. This involves the following tasks where some sort of laser leveling device would be very useful I guess:

 

     

  1. Level the site. A digger/bulldozer will need to make the site perfectly flat before drilling holes for the piles;
  2. Ensure the piles are perfectly vertical before the concrete hardens;
  3. Ensure the piles' tops are at the same level; this might be difficult to guarantee in the first place so I would be happy to cut the tops where necessary once the concrete is hard.

 

What sort of laser leveling device type would be best recommended here? Will something like this suffice:?

How many piles?

 

You could just use/make a water level - that should get it within the margin of error of the saw when trimming them to height.

Any reason you want to buy and not rent one?

It's a 20ft shipping container home. Four piles in the corners and another four in the middle. 8 in total.

Love the idea of a water level. Few 10s of $ of clear tubing and it’s a foolproof method. Nice and simple and cheap.

You don't need to do 2 at all.  Near enough is good enough you will have to trim them to level anyway, just make sure there aren't any too short.

 

A string line and spirit level is fine for most jobs, however lasers are cool.

Wouldn't bother with a fancy laser level for such a small job. Grab a few metres of clear plastic tube from Para Rubber or a hardware shop, a bucket of water, and maybe a stick to tape the end of the tube to. Works around obstructions that a laser won't too!

 

EDIT: if you're trimming to height, it's often recommended to treat the cut end of the pile - Metal X or something similar.

As above - just use a water level.

Not sure why you think this is necessary. You really want fall under the dwelling toward the outside for surface drainage.

hire a dumpy level and the measuring pole with tripod, that would be the easiest and quickest, or hit up a builder and offer him a box for a quick measure up

Haha, the question was not whether to buy or hire but what to buy/hire smile I agree though that hiring is the most sensible thing to do here.

Yeah, I'll probably skip step 1.

You don’t even need to buy a full length of the polythene tubing. Just buy 1/2 metre of tube that has outside diameter the same as the inside diameter of your garden hose. Take the tap fittings off your hose, cut the poly tubing in half and jam each half into each end of the garden hose. Fill with water and the job’s a good ‘un.




Sometimes I just sit and think. Other times I just sit.

Don't just use the garden hose with clear end sections. If there are air pockets in the hose, the water levels at each end will be different.

If the entire hose is clear. It is easy to see if there are any air pockets and remove them. Far harder to check and verify when just using a garden hose.

Yep - when posting this, I did mean to say 'make sure there is no air in the hose'. You can check that all is OK before you start levelling by holding the two ends together side by side and checking that the water levels are the same.

I am not quite sure why you would muck around with trying to use a water level when you could just use a spirit level. A tool that you will already have
