Bedding Sand is Improperly Installed
The bedding sand is a very important part of the landscape. This will help stones to firmly settle into your base and remain in place. It also will provide a layer for leveling out any small discrepancies in your manufactured product and gravel base. But if the bedding sand is installed improperly, you are going to have voids or dips that show up in your finished product. This is even true for interlocking pavers that a homeowner might expect would stay level.
The Base is Not Compacted
Before you lay your pavers or bedding sand, the gravel base must be firm and flat, without any rises or bellies that are more than 1/8 of an inch. This can be accomplished by compacting your pavers and base properly. If you don’t do this, you’re going experience raised or sunken pavers. This is especially noticeable with a walkway, since you can actually see it rise and fall through your landscaping.
Your Base is Too Shallow
When you are digging your base, you want to make sure that you are digging it deep enough. You want to excavate ample work for laying a good gravel base. Four inches is recommended for areas of foot traffic and 6 to 10” is recommended for a driveway. If you are in an area that is really cold with weak or continually wet soil, you want to add another 2-4” aggregate to the gravel base. Any legitimate masonry specialist or paver installer should use these as minimums, not maximums.
