Permeable paving is ideal for a large area, like a driveway. Note the existing catch basin towards the garage door.

Permeable paving is a transformative approach to sustainable site development. Permeable hard surface construction is part of a continuing series of engineering solutions to water management that protects, restores, and mimics the natural water cycle. Permeable paving is an efficient solution for storm water runoff. It will reduce flooding, increase water infiltration, recharge groundwater, improve site irrigation and improve water quality.
Permeable paving is truly a “deep” subject. We have the actual, full-size displays of these at our office.
Unlike regular interlocking pavers that have a base of sand, the base and layout of permeable pavers allow water to soak back into the soil. First, the soil is prepared and topped with geotextile, which helps prevent water contamination. Then, a base layer of open graded compacted (no. 57) aggregate is laid down. On top of that is 1-1/2 to 2 inches of granular bedding material (no.8) that has zero plasticity and contains no no. 200 size particles. The pavers are then installed and the joints are filled with more of the granular bedding material.

Permeable pavers have many benefits:
- Offer long-term durability
- Are easy to repair
- Provide groundwater recharge
- Eliminate standing water on pavement
- Control erosion in streambeds and riverbanks
- Facilitate pollutant removal
- Reduce thermal pollution (the act of altering the temperature of a natural water body, which may be a river, lake or ocean)
- Qualify for Credit 6– LEED: Limit disruption of natural water flows by minimizing storm-water runoff, increase on-site infiltration, and reduce contaminants
- Qualify for Credit 7 – LEED: Reduce heat island effect, when light colored pavers are used. According to the EPA, the term “heat island” describes built-up areas that are hotter than nearby rural areas due to human activities
- Accommodate detention facility requirements
Call today to speak with one of our Landscape Designers to discuss permeable pavers as an option on your property. If you are looking to tackle drainage issues and at the same time, improve the beauty, value and functionality of your property, permeable pavers provide many unique options that just may be the right solution for you.
