Inspected a crawl space that had some weird stuff going on. Looks like 1 main beam was replaced. It was notched and shimmed with quit a bit of shims. What’s the rules with this. Thanks for any help with this
Scrap-wood shims are a no go.
“The only problem with using wood shims arises when the shims are too small to support the weight/load of the main beams. If the shims are cut from the edges of nominal 2x4s, they are only 1-1/2 inches wide. A single sliver of 1-1/2 inch wide shim will naturally crush under the weight of nearly any beam in a wood floor system. All that the builders need to do is utilize a series (multiple pieces) of wood shims when leveling the main beams in order to reduce the pressure on the shims. Usually, they just use a single piece of 1-1/2 inch wide shim. These shims can be �-inch thick up to 1-1/2 inches thick. Whenever the shim needs to be more than 1-1/2 inches thick, the builder will typically use a piece of dimensional lumber such as a 2x4, 2x6, 2x8 or even 2x10 or 2x12. In these cases, the shims will usually never crush. The crushing problem typically only occurs whenever a single sliver of thin wood is utilized.”
& shall be treated material with grain perpendicular to the beam being supported (avoids splitting) & cmu requires masonry cap or top course filled
whenever i’ve done install/repair wood plate shall not exceed 1-1/2" height because masonry cap is available
Just shoddy work. It would not have taken much more time or $$ to do it correctly.
The rule is that there’s more wrong there than just the shims.
That’s a Parallam beam or (PSL).
DO NOT cut, notch, or drill holes in Parallam® Plus PSL except as indicated in the Trus Joist® Beams, Headers, and Columns Specifier’s Guide, TJ-9000.

Appears to me that the block work might have been temporary support and not removed, because a PSL of that size would not need intermediate support.
The CMU on the end support appears to be filled, and should have been trimmed down to allow for a P.T. plate for a full bearing of the PSL without notching of the beam.
On a second note, what is the plastic face insulation? Is it a vapor barrier?
It’s that fully encapsulated stuff that homeowners use so they dont get itchy putting it in. This paralam was a replacement for whatever reason they replaced a double 2x12 main beam with this. Right next to this is a double 2x12 main beam that was either added or is original but it doesnt run the full length of the crawl. It stops on a cmu pier about 10 feet from the next wall. I’ll add some more photos but there was a lot of work done down here and its shoddy.
All kinds of issues there. There are a couple of LVL’s that look like they want to roll over, missing insulation, some falling down, unstable prop to support floor above and galvanized piping and I am sure there is other things that need looked at.
Might be a good time to recommend a qualified licensed contractor to evaluate the whole thing.
Give them some credit, they used a garbage bag or similar as capillary break
That’s basically what I told him. The floors above some of this are unlevel also. For a 1989 build I was not expecting this
Marcel have you ever seen this before? It was shiny but dry on the blocks and some of the insulation. When I first saw it I thought it was all moisture but it’s not. I’m kind of scratching my head as to what it could be.
Can’t say I have. Was that the only small area with those sparkles? Looks like some sort of glitter.
Should have used metal to shim it.
I’ve seen products like Concrobium mold spray leave a glittering film when they dry.
Looks like the film left behind by slugs.
That’s what the buyer thought too. It could be but it wasn’t in trails like you would expect. But you might be right
Yea just one corner of the crawl space. Buyer thought maybe slime residue from slugs. Not really sure I told him I would look into it more for him
Is that an LVL? How many plys ? They notched it so it may not work out anymore. Also how is the plys fastened together?
If this was my inspection I would just state appears to be notched and improperly shimmed. I would suggest a contractor to look at it. I would also suggest checking with local building inspector for proper permits and inspections.
