As temperatures drop, many paving systems are subjected to a significant challenge— the freeze thaw cycle. Water from rain and snow melts can seep into any existing cracks in concrete and asphalt pavements. The frozen water creates internal pressure. Upon thawing, the pressure is released, causing the pavement to crack and heave. The bottom line? The pavement is very likely to structurally fail and deteriorate over time.
This cycle is particularly damaging to traditional and permeable pavements on roads, sidewalks and parking lots. But flexible plastic porous pavers can effectively sidestep this issue. Grasspave2 and Gravelpave2 by Invisible Structures provide viable solutions.
High porosity of the design mitigates cracking
The main concern with freeze-thaw cycles is the development of cracks in the pavement. These cracks compromise the structural integrity of the surface, leading to safety hazards and increased maintenance costs. Porous pavers Grasspave2 and Gravelpave2 have a unique ring-on grid design that enables a high level of porosity. In application, these stormwater paving solutions allow water to infiltrate the surface rather than pooling on top. This prevents the formation of ice within the pavement, eliminating the primary cause of cracking.
Porous pavers’ flexible design makes room for ground movement
Recurring freezing-thawing cycles can cause traditional pavement to heave or uplift. As ice forms beneath the surface, it lifts the pavement, creating uneven surfaces. Not only does this accelerate wear and tear on the pavement but it also poses safety hazards for vehicular and pedestrian traffic.
The flexibility design of Grasspave2’s and Gravelpave2’s ring-on grid design accommodates any expansion and contraction of the ground caused by the freeze-thaw cycle. Unlike rigid materials that crack under pressure, these stormwater solutions adapt to environmental changes, maintaining their structural integrity.
100% recycled HDPE plastic is durable to freeze-thaw effect
The cumulative effect of freeze-thaw cycles accelerates wear and tear, reducing the lifespan of traditional paving systems. Over time, it can lead to potholes that not only pose a safety hazard but also incur additional maintenance costs. This poses a significant challenge for municipalities and property owners who must invest in frequent repairs or replacements. But the innovative design and materials of Grasspave2 and Gravelpave2 sidelines these issues. Made with 100 percent recycled HDPE Plastic, both porous paving alternatives can create a stable and durable surface that withstands the abrasive effects of freezing and thawing cycles.
