Paver Drainage Supplies
Hydraway drainage systems can be installed alongside and underneath porous pavers to effectively mitigate the erosive effects of water on beautiful new patios.
Pavers come in all shapes, colors, and styles and are appropriate for commercial patios and decks and for residential purposes. They can be a beautiful way to line the perimeters of outdoor decks or can be arranged in elaborate patterns to create a unique patio surface.
However, their versatility presents several obstacles that other surface materials may not face—at least not as quickly. A structure constructed of pavers is inherently porous. If the bricks or stones aren’t themselves porous, the spaces between them surely are. The fact that water can seep under the surface of pavers presents a number of problems.
Erosion: This is a particular problem around the edges of your new deck or patio. Even if pavers are there to make the perimeter of your outdoor space an attractive boundary, they do serve a functional purpose. Perimeter pavers are holding back the bulk of the soil that is under your patio surface, the dirt and mulch along flower beds, and many other spaces. Unfortunately, they are no match for the uncontrolled flow of subsurface water. As water flows under a patio or falls onto a flower bed, it will carry with it dirt and silt right past your pavers into the middle of your yard or another undesirable location. Pavers will halt this process for longer than a completely unimpeded flow of water, but they won’t stop it.
Cracking: Cracking is used to describe how water can freeze and expand to create cracks in the surface of a deck or patio between pavers, especially when the water is standing below the surface in the winter. At first glance, this doesn’t seem as severe as cracks in concrete or asphalt caused by freezing water. Although it is true that pavers pushed aside by freezing water won’t always be damaged in the same way as concrete, repairs can still be extensive and expensive. If stones must be lifted, realigned, and laid down again, you may notice that more of the surface has been disrupted than you realized at first glance. Particularly when bricks or pavers are laid out in an artistic fashion, this can be a major headache.
Level Changes: Over time, as water freezes and expands or erodes the soil under or alongside a patio, pavers will begin to shift, creating an uneven, unattractive, and potentially unsafe surface. Problems like this can be expensive or labor intensive to fix, as they involve more than simply laying down new bricks. The soil underneath will need to be replenished before new pavers can be laid down.
