Permeable pavers have become a famous paving technique for driveways, patios and parking lots. Installing these pavers is quite easy and quick. Rainwater runoff can drain through them and permeate into the soil beneath the surface. And this ability is not possible with a concrete material or solid clay. How exactly do permeable work?
Permeable Pavement Function
Permeable pavers come with small joints or spaces between every block paver which lets water drain through. The gaps are filled by sweeping rocks into them instead of using solidifying agents such as polymeric sand or mortar. With the small rocks, a driveway or patio surface is kept solid while letting water to trickle through the spaces.
With conventional hardscape surfaces like concrete and asphalt, water reaches the surface and runs into the direction the surface slopes toward. Often, the runoff flows into the sewer systems and streets. Permeable pavers ensure that surface water stays on site.
Permeable pavers work properly by installing the base material (compacted coarse rock) underneath the surface to some specifications. The load requirements and application of determine the size and depth. The base material filters pollutants and sediments as water trickles down into the earth. In order for the permeable paving system to work perfectly, the base material or joints should not have sand or fines. This is because sand will clog up the gaps and prevents proper water flow.
Choice of Permeable Pavement
Permeable pavers are designed and made to give enough space between blocks to allow water to drain through. The size, material, arrangement, and color of the paver are customizable. When it comes to what’s pleasing to the eyes, the decision is based on the budget, location, and purpose.
As permeable pavement continues to be a pavement of choice for many, it has become more important to understand its function. Although it may look like an ordinary driveway or patio, when water reaches the surface it will drain through gaps and into the soil. Permeable paver system installation is important when it comes to filtering sediment and maintaining durability.
To ensure a problem-free installation, it is necessary to find the right contractor. This can only be possible if proper research is done. There are a lot of companies that claim to be the best paver installers so make sure you end up picking a reputable one.
