In Montreal, there are many retaining walls made of concrete, wood or interlocking paving stones, which hold back soil and vegetation. Over the course of 20 to 25 years, wood and interlocking paving stones deteriorate and become unsafe.
But there is a sustainable solution to this problem. A concrete wall that stands up to punishing outdoor conditions for 80 years.
If your building was erected many years ago, your retaining wall is probably concrete. Is it broken, cracked or compacted by the force of the soil? You need to check because although concrete is very resistant, it does not last indefinitely. Your retaining wall may collapse.
