Question about screw piles
 

Looking to build a deck. Maybe attempt it ourselves, but have to get a contractor to put in screw piles.

What i don't know is how high to get them? How are you supposed to know? The height of the bottom of the deck is dependent on how wide the material is. so What if the screw pile is a few inches too high or too low?

Dont you get them a little higher then deiced on everything else test fit measure 3 times then cut them 2 size? I was a kid when my parents built their deck

Edit: see memes below for full effect

Pad footings won't do the job?

I remember screw pile once may years ago. Was back in the army days in Germany and we hired this hooker and..... Oh wait. Building a deck? No idea.

seriously, wat? lol

Screw piles are a lot sturdier

you dirty dirty man. i bet you were in the middle

I am just making shit up :lol: I have no idea what we are talking about

Depth and circumference of the screw pile are the important factors. The height can be trimmed as you'll cap them to take deck bearers.

I have a question about screw piles too.

What the fuck is a screw pile?

I am not sure there are no memes about them

NVM found some

Takin it back, you are ft86 club's Randall.

Not sure in Edmonton, but here generally its less expensive to auger post holes and do concrere piers (Sono tubes). I am in the pre-eng building business. Screw piles afaik are widely used where getting concrete to site is not practical or cost effective for some of our clients, for example fairly large industrial building foundation in northern SK. This is just a deck. Home Depot should have the answers and auger rentals, or a local contractor.

I worked at a deep foundations company for many years. We installed those screw piles, helical piers, push piers, whatever you want to call them.

The tip elevation, how deep the pile goes, will depend on the quality of the soil and the size of the bearing plates. The installer will keep driving them in until a minimum depth and resistance is reached. Extensions are connected to the lead pier to make sure the whole pile is long enough and you have something to connect to.

Once everything is installed, you can frame out your patio, figure out what elevation the cap for the pier needs to be, etc., then the last thing you do is cut the pier to the right elevation. The top of the pile gets cut to the right elevation rather than having it driven to the right elevation.

I suggest you get a quote from a contractor to put these things in. They'll have the right equipment to get everything to the right depth and in plumb. Most importantly, if any problems come up, which they always do, a qualified contractor will have the tools and know-how to deal with it.

If you have any questions, feel free to PM me.
