Deck building


Coldiron, you have a point, and I agree that you don't want a shoddy pos built, but commerical construction that lasts forever doesn't use much/maybe any? PT wood that sits exposed to the elements. Everything is steel and concrete. Decks are wear items, since they're exposed to the elements/etc. Regarding how long a deck lasts, the decking may only last 14 yrs, but the framing should hopefully last a lot longer than that. If people had to redo their entire deck every 14 yrs there'd be a lot more patios.. :p

They probably do. Look at my house. It had a bad leak underneath and contractor put foam around it to stop it long enough for me to sign the paper work on the house. Now a crack in my foundation has been discovered (may or may not be because of builder). The house is only 14 years old and its having problems I might expect form a 100 year old house. It's a little ridiculous. Obviously people don't care about longevity anymore and only want a pretty finished product long enough to get paid.

Anyway, ledger being put up as I type this and posts should be set after if weather permits. Progress is being made.

What is that plywood looking material that is used in floor joists/band boards called? The joists look like 2x on top, plywood looking stuff in middle, and 2x on bottom. I-beam is what they are called. Anyway, how is that stuff strong enough to support a house? Is it reall as strong as old style thick wood joists?

sounds like you are talking about I-joists which use Laminated Strand Lumber (LSL) rim boards, typically 1-1/8" to 1-1/4"

Is this stuff really strong? With my lag bolts at every 4" a lot of the go through this material after the ledger board. I'm assuming this is just extra support because there are a lot of lag bolts!! Lol

The lags are 5 1/2" long and 1/2" diameter. Code says to start 2" from edge and place a bolt every 4" in a W pattern.

The posts did not get set today since problems came up while installing the ledger (cracked foundation). He is going to finish up the ledger tomorrow and set the posts in the morning. There's a chance of rain tomorrow night and its going to rain Wednesday for sure. Will it be okay? Could we just cover the concrete with plastic for a day or 2? This would be a big set back. I swear it rains every other day around here lately. At this rate the deck may never get built and walking my dog around to the back yard is getting old quick on these cold nights.
Should I just scrap it until Friday when its "not going to rain"?

in comparison to the building materials that we have now compered to 100 years ago we have maybe 20 percent the strength of the old growth lumber used back then, and that translates to every piece of wood used in the house, framing - trim, cabinets, etc.... the only thing still the same is brick and mortar and some types of roofing. I've always thought that commercial type building ( metal framed buildings) would lead more into the residential sector but wood still rules.

if you are able to, put up some plastic over the holes that is like a tent and drains the rain water away from the holes. you will get seepage from underground water still but if direct water is re directed it isn't as bad.

Just found out its supposed to snow Wednesday and maybe Thursday. Its a double whammy of wetness and cold so it looks like no concrete until Friday if the ground is not covered in snow then. What a way to start march!

If only more people would realize this... Quality of lumber has gone to absolute crap.

Anyone care to comment why lumber has gone to absolute crap? Is it just that we've cut down and used all the "old" trees, and instead are using younger trees for construction? I guess older trees/wood is harder/of better quality than younger/newer growth? I've heard this from so many people but haven't heard anyone explain why. Thanks.

I know that back in the day a 2x4 was actually 2"x4" where as now they are 1.5"x3.5". Same goes with all size wood. I'm sure that is a big part of it. Also, wood is treated differently now due to new laws and the old cancer causing chemicals or what ever that used to be used. In California everything causes cancer. Don't know about the new vs old trees but it seems like younger trees would be stronger but also more prone to warp and twist.

Wow, wood was actually its stated dimensions back in the day? You sure about that, just seems odd how they'd suddenly start shipping things smaller.. but stranger things have happened. I'll never forget the first time I went to buy some wood for a little table I was building.. I didn't measure it at the store and brought it home, measured it and it was too small.. I was like WTF?!

Well I know the pressure treated wood for outdoor use is different now. No more CCA except for commercial use, and now there's mca/mcq/etc. My understanding though it the actual lumber is of worse quality and less hardy which is why it's less durable/doesn't last as long..?

Edit: I guess this explains it.. http://www.humboldt.net/~hrsp/oldgrowth.htm Older growth have more tightly packed together growth rings = tougher/stronger wood.
