Pavers form beautiful surfaces for driveways, patios, pathways and other areas, offering a variety of shapes and patterns. However, over time, individual pavers can shift and develop other issues, and the surface will need repairing. Here are some signs to watch out for.
While pavers are sturdy, cracks can form across the surface that are caused by water, chemicals or natural weathering. Fine hairline fractures aren't an immediate danger, but they can deepen to weaken the integrity of the tile. Repairing the paver in a timely fashion will possibly prevent it from needing replacement.
Individual tiles should fit snugly together, forming solid and stable footing. If you notice the ground moving underneath you as you walk, it's time to consider paving repairs. After all, safety is paramount. The base underneath the pavers—whether it be dirt, sand or crushed stones—may have shifted, resulting in the instability.
An uneven pathway that goes up and down, with some pavers protruding above others, is hazardous. It could result in trips and falls and make pushing prams or bikes tricky. The base underneath can settle unevenly, creating an irregular surface. After restoring the support, the tiles will fit more smoothly, whether the pathway is flat or sloping.
If your pavers have faded or discoloured, they might benefit from a new coat of a sealant or another protection. However, weathering can add to the charm and character of the surface. With cosmetic issues, it all comes down to the eye of the beholder.
Crushed stone and other base materials help to drain water from the paver surface. If you notice water pooling on top, you should consider pavement repairs. This pooling could be due to a combination of heavy rain and an uneven surface or slants that encourage puddles to form.
In any case, the structure should allow for adequate drainage in normal conditions. Contractors might examine the slope of the ground and whether the paving needs inlets to drain water to an underground trench drain, for instance. They may also look at if a curb will help to contain and direct water flow away from the problem area. Water can result in cracking and other damage being done to the pavers as they weaken from the constant exposure.
While pavers are incredibly durable as well as decorative, they do need some care. If you notice movement, unevenness or water puddles, don't hesitate to have the surface examined and fixed to prevent further problems developing.
