Paver Repair & Re-Sanding in Highland Township

Frost heave needs three things at once: freezing temperatures, a soil that wicks water, and water for it to wick. A North Dakota Geological Survey summary puts silts, loams and very fine sands among the soils that heave worst, while clean, well-drained gravel rarely heaves. The township's equestrian farm country runs to sandy loam, though what counts is the soil under each patio's base. As water is drawn up toward the freezing front, it builds ice lenses that lift the surface above them. The damage comes from the lift being uneven, one corner of a patio rising while the middle stays put.

Thaw is the second half. The ground thaws from the top down, so meltwater gets trapped above soil that is still frozen, and the softened soil loses strength; a refreeze makes the heave worse. Ground lifted by frost can settle back as it thaws, which is why we judge a lifted patio after thaw, not in February.

A reset has limits worth knowing before you book. The Concrete Masonry & Hardscapes Association (CMHA) gives a frost-resistant subbase as the remedy for heave, which is deeper work than relaying pavers on what is already there. Our repair lifts the pavers, corrects the base under them and resets them, which levels the surface without adding that subbase. A sunken patio at a cottage near Duck Lake or on White Lake's west shore starts with the same question as any other, why it dropped: CMHA lists a saturated base, washed-out bedding and poor compaction among the causes, and the fix depends on which it is.
