Sidewalk Repair and Trip Hazard Removal

Yes, when the higher panel is sound, stable, thick enough, and the resulting transition meets route and drainage criteria. Precision grinding is not suitable for rocking slabs, deep cracks, widespread scaling, severe root heave, or base loss. Harrowgate measures the profile and selects repair rather than treating every offset the same way.

Replacement is appropriate where concrete is structurally broken, deeply scaled, unstable, badly sloped, extensively patched, or displaced by base, utility, root, or frost conditions. It also allows correction of thickness, drainage, joints, and route geometry. Harrowgate removes to controlled boundaries and repairs the underlying cause before repouring.

We phase panels, establish a signed alternate route, protect door approaches, and schedule demolition and pours around peak operations. Temporary bridging is used only when designed and safe. The repaired route remains closed through the required cure period, then transitions and rail or door interfaces are checked before reopening.

Cross slope is measured perpendicular to travel at multiple points across each panel and transition. Harrowgate sets forms from survey and checks concrete during strike-off because local dips can exceed criteria even when edge elevations appear correct. The applicable accessibility standard and approved drawings govern the acceptance value.

Frost-susceptible soil, trapped water, poor drainage, roots, shallow utilities, and uneven base can lift panels. Durable repair requires drainage and support correction, not just surface patching. Harrowgate removes weak or wet material, places compacted granular, follows joint details, and protects the new work from water entry and early freeze.

Root work requires coordination with the owner and arborist because cutting major roots can destabilize or damage a tree. Options include selective root treatment, route adjustment, structural bridging, flexible zones, or panel reconstruction. Harrowgate follows the approved tree-protection approach while restoring base support and route geometry.

Reopening depends on mix, weather, curing, test or maturity information, panel thickness, and project requirements. Harrowgate maintains barriers until the required opening strength and safe surface condition are reached. Heavy carts, maintenance equipment, and vehicles may require a longer restriction than ordinary pedestrian access.
