The AB Courtyard patio wall system is a grouping of modular concrete blocks. The blocks stack easily together to build great enhancements to your patio.
One of the benefits is the size of the two main blocks – AB York and AB Dublin. The AB Dublin is exactly double the size of the AB York stacked next to each other. This makes it easy to switch between the blocks or substitute one AB Dublin for 2 AB Yorks in the project.
When building with both blocks they can be stacked with no set pattern and end up with an impressive final project.
