There's not too many homes with basements here in the PNW due to the large amount of rainfall we receive, some issues with radon intrusion, and the fact that our frost line is only 24", so we can't speak to this exactly. However, I do know that sometimes people in other areas daylight a drain for the sump to prevent water build up. You can also waterproof your foundation wall where the permeable pavers will be.
I have a question, I have about 300sq foot hole in my back yard that is 5ft deep. My back yard is pure sand, so it has great drainage. Instead of making a sunken patio I would like to make a flat permeable patio that is even with the lawn. Should I add sand back into the hole until I have a hole that is only 1ft deep or should I be adding gravel to the hole? Since sand doesn’t really compact I’m afraid the patio will become uneven after a few years. Any info would be great.
You should never fill in a hole with sand or soil and then pave over the top. As you state, it will settle, and sometimes it can do it quite dramatically. The hole needs to be filled with compacted gravel to prevent settling. Since your hole is so deep, you can start with a mix of larger materials like we did here, compacting it as you go either with a jumping jack or plate compactor. When you get near the top (somewhere in the last 15"), switch to compacted 1", 3/4", or 5/8" open gravel (depending on what you can get), stopping at 3" from the final grade to allow for your pavers.
@@WesternInterlock would you suggest using 2 inch clean crush for the compacted gravel? And should I be compacting it every 3 inches since it’s so deep or can I get away with 6 inches until I get closer to the top?
The 2" clean crush will work just fine. We used 3", but it's a bit hard to work with without equipment. How much to compact at once depends on the compactor that you use. Every 3 inches will be safe.
It only really matters near the top. However, it will be less work overall if you try to eyeball it level as you fill. The flatter the base, the flatter the patio. Any humps or holes in the base will most likely telegraph up through to the pavers.
I have a 160 sq. Ft. Area between the house and garage I wanted to put regular pavers on. The problem is that the pavers would be lower than the land that I would be sloping towards. That’s why water pools up in this area that I want to put pavers in. Would permeable pavers work for me and keep water from sitting against the house and getting into my basement? I’m not having seeping in my basement now even though water is pooled up against it some.
Permeable pavers would actually be a perfect solution for something like that. I'm not sure where you live, but if you're worried about high quantities of water, it would be best tie the sump that goes underneath the permeable pavers into some sort of drain line. I would also dig it out a bunch and build a dry well underneath the permeable pavers.
You can see several drawings of different styles on this page: icpi.org/permeable-interlocking-concrete-pavement-drawings Basically just expand the bottom layer of rock to handle the anticipated water. We're in Oregon, so I can't give you site or regional specifics.
Yes! It will totally work for a driveway. In fact in this video, this was a driveway extension. Just be sure that you use appropriate compaction and geotextiles.
Great info! a couple questions: what rock do you prefer to fill joints? The #10 1/4" crushed , open fine?
Here in the PNW we like 1/4"-10 crushed open.
I need done my driveway sun it possibly before winter
You can definitely do it yourself! Just follow these instructions.
Thought on permeable pavers and basement water intrusion?

I need permeable stone to do driveway
Permeable paving should be used more!
We agree!
after you have put the cement in for the edges, do you NOT compact the edges?
Perma Edge recommends compacting the project before the cement sets up, so you do it right after it’s installed.

@@WesternInterlock thank you, One last question, does it matter if the gravel is perfectly level when I begin to fill in the hole?
It only really matters near the top. However, it will be less work overall if you try to eyeball it level as you fill. The flatter the base, the flatter the patio. Any humps or holes in the base will most likely telegraph up through to the pavers.

@@WesternInterlock Do you have a picture or video of what this looks like. I live in South Holland, Il.

@@WesternInterlock What is the curb or the big block in the pictures?
It's for commercial parking lot applications. We recommend using Perma Edge.
Would this work as a driveway?
Yes! It will totally work for a driveway. In fact in this video, this was a driveway extension. Just be sure that you use appropriate compaction and geotextiles.
Can this be done to steps?
Steps themselves can not be permeable, but the landing at the bottom could contain some permeable pavers.
