Water Permeable Interlock

Lots of Ottawa clients are looking for more eco-friendly options with their landscape design.  Water permeable solutions have all the benefits of a traditional installation but can help mitigate against excessive water collection.  Help the local environment, reduce stress on city sewers and become a champion of the local ecology. 

What Are Permeable Pavers?

Permeable pavers allow water to flow through the ground level and disperse back into the soil under your foundation. The objective is to let as much rainwater to pass back into the environment without running off into the local sewer basin.  

What Are 2 Huge Benefits Of Permeable Solutions?

1. Water can return naturally and flow into the ground table instead of increasing demand on city infrastructure. 

2. Your landscape acts as a filter and removes contaminants and particles that would have normally been washed away with the rain water. 

Where Can Permeable Pavers Be Installed?

  • Residential roadways
  • Sidewalks/paths
  • Patios
  • Retaining Walls
  • Parking Lots
  • Swimming pools
  • Driveways
