Planning for GTA freeze-thaw
Durable hardscape begins below the finished surface with preparation, compaction, drainage, and restrained edges.
Movement is part of the climate
GTA winters repeatedly move moisture through freezing and thawing cycles. Good planning manages the conditions that contribute to settlement and movement rather than pretending they do not exist.
Base preparation and compaction
Excavation depth and base construction are selected for the site, intended use, soil, access, and project standard. Preparation must be consistent, not only deep in isolated areas.
Water management
Surface grading, drainage paths, downspout conditions, and adjoining elevations should be considered together so water is not trapped where it can create avoidable problems.
Details complete the system
Edge restraint, cuts, transitions, and the relationship to steps and walls help the paved area behave as one coordinated system.
