Many Coquitlam neighbourhoods, like Westwood Plateau and Burke Mountain, are built on hillsides, so retaining walls, proper grading and drainage are essential for safe, usable yards. Heavy rain on sloped properties can cause erosion and shift patios, walkways and driveways that weren't built on a solid base. Coquitlam also has many new homes and strata communities that need finished outdoor spaces. Professional hardscaping and landscaping in Coquitlam turns hard-to-use slopes and bare lots into attractive outdoor living areas that last.
