Wet cutting is usually the preferred method. It controls dust, which helps protect your lungs and makes for a cleaner working environment. Plus, the water cools the blade, preventing overheating and prolonging its life while providing smoother, more precise cuts. The downside is the mess—water and asphalt sludge can be messy to clean. Dry cutting, though convenient if water isn’t available, creates a lot of dust, which can be harmful. This also increases the risk of blade damage due to overheating. So, if you have the option, wet cutting is the better method for most asphalt jobs.

After removing existing moss, consider using paver blocking sand to fill the joints. This specialty material hardens once placed and serves as an effective barrier against moss and weeds. From there on, regularly clean your pavers and try to keep them dry. You can also seal your paver as a semi-permanent solution — just make sure you reseal every 3 to 5 years.

Building a road on a slope requires careful planning and will normally require a drainage system underneath to prevent flooding and damage to the road over time. Your professional may lengthen your road to create switchbacks if the slope directly to your home is too steep, as there are regulations for maximum road slope. The drainage system will help prevent runoff from the higher side of the slope from damaging the asphalt or concrete. Keep in mind that building a road on a slope isn’t a good DIY project, as a lot can go wrong.

Yes, but it's best to kill off the grass with solarization and remove the dead plant matter before laying down the pavers. This helps limit the chance of your pavers shifting as the dead plant matter decomposes.
