Best way to clean organic stains on concrete driveway

We recently had some landscape work done in our backyard and the crew used our driveway to store their materials such as pavers on pallets and loads of dirt and rock that they placed on plywood. So for about 6 weeks the material sat on and driveway and they just finished, removing all of the pallets and plywood which had a lot of staining beneath it. I tried power washing with my 3000psi machine and there is still quite a bit of stain remaining.

is there a product I can apply to the driveway that will removing the staining?

What is the driveway..... concrete, asphalt, pavers ?
Organic stains would be from dirt..... not grease or oil. Is that correct ?

It’s concrete and I believe the staining is some from the dirt that with wind and rain collected under everything. It’s not oil.

I'd start with detergent/bleach and a pressure washer [wide tip] Stubborn areas may need to be scrubbed with an old broom.

If the pressure washer didn't clean nothing else will!

If it's cleaning and just the shear volume that is a problem get a plate cleaner!

Hi, Any suggestions for attaching an Iron Gate to split face block? I have two columns that I want to put an iron gate between. I am not sure how I can get it even, with the uneven faces of the split face block. Any help, suggestions would be much appreciated. pb4sc

I need your advice with pouring footers for a pergola

J

JaredSD on Oct 19, 2020

I am starting to excavate my backyard for a project, and the next step will be to pour concrete footers for a pergola. The pergola uses a bracket system, and the footer in this system has its own holes for attaching to a concrete footer. This is to say, the pergola will be on top of the concrete footers and not set in the concrete. The pergola posts will be 6x6, but really I am dealing with something a little larger as the bracket is 8x8 (11.31 inches diagonal). You can see the product link [url=https://tojagrid.com/products/copy-of-grid-solo-4-pack-for-6x6-wood-posts-shipping-feb-18-22]here[/url]. I have been reading about this online and it seems there are a ton of moving factors here. I will list out the things I am trying to figure out. 1. Some people have said to dig a bare hole and pour concrete into that and other have said to use a Sonotube for the form, and pack in earth around the Sonotube. I think a Sonotube would be easier as that would give me a really clean top to work with. 2. If I use the Sonotube, will a 12" inch one be wide enough? The drill holes in the bracket are 7.5" apart and the bracket itself is 8" wide so I am good there. A 12-inch one also is just wide enough to accommodate the 11.31" diagonal of the bracket. I don't see any forms larger than 12-inches so if I need to go bigger I would have to custom build some out of wood perhaps. 3. I also need to think about proper depth. I live in Austin, Texas where the frost line is about 12-inches. However, I have a lot of clay in my backyard and I have heard I should do 24" inches to give it a better footing as the clay will expand and contract. 4. Is there anything else I am not considering? In short, I just need to pour concrete footings for my pergola. I want to do it myself to save some money but am willing to take the time to do it right. Thank you very much for reading this and offering any help. I greatly appreciate it!
