How to Install Keyhole Pavers

Keyhole pavers get their name from the shape of the paving stone. Seen from above, the pavers resemble a keyhole, with a hexagonal main body and a rectangular extension below. The pavers lock together into a distinctive and attractive pattern when laid on a walkway or patio. Keyhole pavers install in the same manner as normal pavers, with the exception of the set installation pattern.
