Granular Base and Subgrade Prep is the placement and compaction of engineered granulars that support pavements, slabs, and structures. Every granular base and subgrade prep project Harrowgate Group takes on in Peterborough is scoped to one site, the ground, the loads, and the constraints assessed first, then the work completed to grade.
Peterborough granular base and subgrade prep work centres on roads, lots, slabs, and pads. The recurring drivers are a compacted, free-draining base that carries load without failing, each Peterborough project is scoped to its own situation rather than a standard package.
Demand for granular base and subgrade prep in Peterborough (Peterborough County) comes mostly from manufacturing, institutional and university, healthcare, and commercial development. Peterborough's manufacturing, university, and healthcare base drives a diverse industrial, institutional, and commercial construction market. Work spans industrial and institutional site development, servicing, and concrete.
The work concentrates around the industrial parks, the university and college district, and the Otonabee corridor. Harrowgate Group regularly builds granular base and subgrade prep for Peterborough clients like manufacturers, the university, hospitals, and the City of Peterborough, each project carrying its own site and requirements.
Peterborough buildings vary widely, manufacturing, institutional and university, healthcare, and commercial development, and the right granular base and subgrade prep approach changes with each. Harrowgate Group reads the property before it scopes the project.
In Peterborough, the work has to account for Otonabee River and floodplain context, mixed older industrial stock, and institutional-campus growth.

Every Peterborough granular base and subgrade prep project follows a disciplined sequence: site survey and layout, utility locates and protection, excavation or preparation, the core work built to the engineered drawings, backfill and compaction or finishing to grade, and site restoration, each stage inspected and documented for the project file.

The crew builds to the engineered drawings and coordinates the inspections and approvals, so nothing on the Peterborough project falls between design, permit, and field.
On a typical Peterborough project the granular base and subgrade prep work covers roads, lots, slabs, and pads around the industrial parks and clients like manufacturers, each scoped to its own situation and recorded for the file.
