Why do the joints on lawn edgings break?

This is one of the most common issues with plastic lawn edgings on the market today! Why does this always happen? Even on my own installations, I was never shocked to see the the joints breaking and heaving out of the ground.

There are multiple factors that contribute to this problem. 

• Expansion and contraction of the edging material.

• Ground movement 

• Staking practice and type of stake used

The reason for this is simple! All edgings will expand and contract. Yes, even concrete curbing and metal edgings, just less than plastic edgings. The ground expands and contract also. The stakes are the only part of the edging system that are stationary. With the stakes being stationary, the edging is forced to expand and contract between each stake. This force will either break the hardware holding the stake to the edging or lift the stake out while still being connected to the edging. Either way, it is almost impossible to get the edging back to its original place of installation.

The answer is to allow for lateral movement and pre-forming.
