Hey everyone! I'm redoing my backyard and planning to install a paver patio. I ran into some differing opinions from two companies I spoke with. One claims that a 4-inch base of crushed stone is necessary for stability, while the other thinks 2 inches is enough for foot traffic since that's less expensive. Both have solid online feedback, so I'm a bit confused. I want to know if having a 4-inch base really makes a difference in preventing shifting or if 2 inches will suffice. Also, is it important to avoid using recycled material for the base? Any insights would be appreciated! Thanks!

Here's how I do it: I start with a layer of landscape fabric over the native soil, then add 2 inches of #57 stone for drainage – make sure to wet and pack it with a compactor. After that, I put another layer of landscape fabric and finish with 3 to 4 inches of crushed concrete or paver base, packing every 2 inches. This will definitely last for many years!
I think it really depends on your location. I usually recommend a minimum of 6 inches for durability, but what you need can vary depending on usage.
In my experience, the base is crucial for a solid patio. I always use at least 4 inches for both patios and walkways. A key tip is to ensure they lay down a separation fabric between the native soil and the first layer of your base. While crushed concrete can work, most manufacturers really recommend 3/4-inch stone instead. Also, try to avoid stone dust since 5/8 stone is becoming the go-to as it drains better and compacts nicely right after spreading.
Thanks for the reccos on the type of rock. Are you saying 5/8" is what you'd recommend? I think that's what you're saying, but it came right after your comment about not using stone dust, so I want to make sure that 5/8" stone is not related to stone dust. Thanks again!
