Interlocking Paving Stones: What Are They and Why Should I Choose Them for My Home?

Feb 26, 2018

Interlocking paving stones, also known as pavers, date all the way back to Roman times. These stones were even integral in the construction of the Great Wall of China. However, just within the span of the last decade or so, interlocking paving stones have become the most popular choice for hardscaping outdoor spaces. Perhaps you have seen these gorgeous stone driveways and patios, but you’ve wondered, “What does interlocking actually mean?” Here is a quick breakdown: An interlocking stone structure is created when independent stones are bonded with paving jointing sand. This material “interlocks” the stones so that they can withstand the weight of large groups of people, and even full-sized motor vehicles. There are many different advantages to choosing interlocking paving stones for your hardscaping needs. Here are just a few of them:

Pavers Shift Are More Flexible
The common alternative to interlocking paving stones is to use concrete or asphalt. Both concrete and asphalt are considered “rigid systems”. This means that they do not have the ability to move or change position as the ground shifts underneath them. Shifting earth, which is an inevitability, can cause bends, breaks, cracks, and chips in concrete or asphalt. This is not the not case when it comes to interlocking paving stones. Since pavers are actually individual stones held together with jointing sand, they are able to flex and move. When the ground shifts below a paver driveway, the stones shift right along with it. This quality makes pavers more durable and less likely to crack.

Pavers Are Easy to Repair
In the event that one of your paver stones does become damaged, it can easily be removed and replaced. Concrete and asphalt, on the other hand, are very difficult to repair. Changing out a paver stone could very well be a DIY weekend project. Whereas asphalt or concrete must be repaired by a professional at a hefty cost. Furthermore, a patch of repaired concrete or asphalt will never quite match the original. Since interlocking paving stones are already varied and unique, a replacement stone will fit right in with the others.

Pavers Absorb Less Moisture
Interlocking paving stones are extremely dense, and they hold very little air. Concrete, on the other hand, is riddled with air pockets. Air pockets do two detrimental things: they increase the probability of breaks and cracks, and they allow for greater moisture absorption. Since pavers absorb less moisture, they are less prone to swelling, and thus more durable in a wide-range of climate conditions. A cold, damp winter will have no effect on your interlocking paving stones.

Pavers Look Stunning
Beyond the numerous practical reasons for selecting an interlocking paving stone driveway or patio, these structures simply look amazing. Interlocking paving stones can add texture and contrast to your landscape, while giving your yard a pop of unique color. A rugged-yet-classic interlocking paving stone driveway, walkway, or patio could be a lovely addition to your Rock Valley, Iowa or Sioux Center, Iowa home.
