The Dead Blow Hammer from Bon Tool is totally covered in a rubber shell, so it will neither harm or leave markings on stone pavers. Wight claims that the 11-inch-long hammer can do more than just tap stones into place. "The longer handle provides greater leverage," he explains. "It's used to level and align pavers."
The tool is designed to work with a pneumatic compressor. However, if you don't have access to one, there is an electric model available from Bon Tool which works exactly like its gas-powered cousin.
There are several types of pavers, each with their own requirements for tapping them into place. Boulders need to have any embedded trees or roots removed before they are laid. They should be flat on all sides except for perhaps a slight concave shape to help them sit properly on a surface. If boulders have holes in them, this will affect how much weight they can hold; the heavier the rock, the thicker the slab that needs to be laid to support it.
Slabs are large enough to see over a garden fence or under a deck. They usually range from 2 to 4 inches thick. They are generally rectangular in shape with four edges: top, bottom, left, and right. The top edge should be beveled (sloped) to allow water to run off. The back side should be struck with the hammer to achieve a flat surface.
Concrete pavers may be put over existing poured concrete slabs in pretty excellent condition with careful installation. This is referred to as an overlay, and it may be a terrific, low-cost alternative for many people. The paver should be large enough so that its edges sit on the edge of the old slab. It should be leveled with a level before being placed on top of the slab. Then, if necessary, fill in any dips with gravel or colored stone to make it look nicer. Paving stones are available in a wide variety of colors and styles, so they can add to the beauty of your yard without breaking the bank.
The best part is that an overlay only needs to be done once. So, if you want to change the look of your driveway, walkway, or patio, just have a contractor install new pavers and you're good to go!
Overlayed concrete slabs can look great, but they can also wear out over time. If you plan to use the surface regularly, such as by walking on it or using it as a parking lot, then it's a good idea to invest in a quality concrete paver product. These products are designed to last for years if not decades under normal use conditions. For example, some popular options are granite-look paver blocks and colored concrete paver tiles.
Yes, if used appropriately, rock salt is safe for pavers. When it comes to salting your patios or walks, keep in mind that safety comes first. You may clean your pavers with rock salt or calcium chloride. The majority of concrete pavers are made to have a very high compressive strength (8,000-12,000 psi). This means they can handle heavy loads without breaking.
Salt does not evaporate or dissolve into water like liquid fertilizer would, so it's not likely to cause problems for plants or walkways. The main issue with salt is the effect it has on bacteria and other organisms. Bacteria need sodium ions to survive and reproduce. If there is not enough salt present, then these bacteria will die off which could lead to problems for people who are allergic or sensitive to antibiotics.
Too much salt can be just as harmful as not enough. If you use too much salt, some of its ionic content will leach out into the soil or pavement. This can actually harm plant roots by making them too salty. It is best to apply only as much salt as is needed to prevent disease and ice formation on exposed surfaces during cold weather.
People sometimes use salt as a weed killer. This application method is not recommended because it can be toxic to plants even at low concentrations. Salt also breaks down plastic piping used for sidewalks and driveways, so it should not be dumped in trash bins located near plants or gardens.
