For nearly 30 years, Alpha Structural, Inc. has developed a powerful reputation as the number one foundation engineering and repair, landslide repair, earthquake, and structural rehabilitation contractor in the Los Angeles area. The company has over 400 years of combined technical experience and all of it is hard-core and down-in-the-trenches, not managed from behind a computer.
Alpha Structural, Inc. also shares photos from its engineers' day-to-day work, including all the funniest, most bizarre, and downright dangerous things they discover. We've already covered their finds here, here, and here, but recently they've unearthed more surprising treasures, so we put together a new piece on them.

Here we have a brick retaining wall experiencing surcharge from the neighboring hill. Structures that are settling can cause this surcharge in the soil. This creates a high-pressure situation which then pushes out the remaining soil and results in this type of damage to retaining walls.

Being that my company in LA does this sort of repair/prevention work, this was some scary news to see this morning. Torrential rain and debris caused a large chunk of Highway 1 on the West Coast of California to wash away.
You're going to need yourself a Yoshi if you're wanting to cross here. Back in 2017, a massive landslide covered up over a half mile of the road. It took months to clean up and there was no access around it. If it continues to rain, I wouldn't be surprised if more of this happened in and around Southern California.

I guess the original builder of this property chose the ancient Roman vibe for this foundation.

We think this takes the cake. This is not rebar. These are old Helical Piers from the 70s. It has never been a method that we have used as a company and this is why. They are very practical in many situations, but for steep hillside and seismic zones, they are not. We've seen this all too many times in LA.

This concrete patio is sitting on a retaining wall that has been pushed outward due to what is known as a surcharge, or hydrostatic pressure build-up. Hollow areas formed under the patio, causing the cracking and further sinking of the patio from the roof load above

The side of this property is sinking, causing this column to lean backward, bringing the connecting beam forward in the other direction. It could slip in the future if it goes unhandled.

Notice the compression of the posts into the girder. They go into the girder about an inch. This property has some crazy settlement and moisture problems

This doesn't happen with just a gust of wind... though that might be all it would take to bring it down

This deck system uses an angled beam that attaches to the concrete patio below for support. The very edge of the deck is beginning to dip down, causing a lot of tension where the beam meets the patio. If you look closely, you can see the concrete lifting with the beam. No partying on this deck for a while!

We’re earthquake retrofitting this building and discovered a few columns that were completely corroded at the bottom. Scary...
