Asphalt and tarmac are not the same thing. Traditional tarmac, short for tarmacadam, uses tar as a binder to hold crushed stone together. Asphalt uses bitumen—a byproduct of crude oil—to bind aggregate. Though tarmac was once a go-to for roads, asphalt has become the modern standard. And these days, most surfaces referred to as “tarmac” are actually asphalt. So, while the names may overlap, the key distinction lies in the binder—tar for tarmac and bitumen for asphalt.

Pavers will crack in a fire pit if they are made of the wrong materials. Be sure to use kiln-fired brick paver stones when building your backyard fire pit. You can also purchase a fire pit project kit, which will sometimes come with fire-safe pavers, to help you avoid the guessing game of buying pavers separately.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

The best way to stop your pavers from sinking is to ensure you've properly compacted the base layers. Use your paver compactor and work over the base layer several times to create the hardest possible base. If the soil and sand of your base are compact, you’ll experience less shifting and sinking.
