Pier to Beam shims

4271 Views 6 Replies 6 Participants Last post by  Gary in WA
I have about an inch to make up between three newly adjusted brick piers and a 3-2x10 Beam. I know that the shim material is supposed to be non compressive and I am looking at a few metal options. It would be easier and cheaper to use wood and I have some scrap oak that would fit perfect. Are hardwoods considered non compressive if loaded along the grain? I need to make sure it's right before the building inspector stops by. Thanks for any advice .

I would use metal. Or possibly even plastic...such as a piece of trex decking to build most of the ace and then metal. Ron
That's a great idea. Trex should do the job!
You might get better results with a non-shrink grout. Just make sure you put some sort of moisture and insect barrier between the grout and the wood.
Thin trex material is friable. Don't use it to support a load. Metal shims are best. Box stores: plumbing, electrical, and lumber hangers have thin metal plates and infinitely adjustable.
pressure treated plywood as long as you dont exceed it limits.
Welcome to the forums!

Plywood is compressible and will absorb water/moisture, as will Trex with 50% wood dough (also molds/rots). I second the grout/vb as you will then meet code minimums- BUT, always good to check with local AHJ; eg.-"
Shims for floor joist or girders shall be of hardwood or steel
plates. Shim width shall not be
less than girder width." from;\AH.pdf
