Interlock Contractor in Burlington

Interlock Built for Burlington's Clay and Slopes

Burlington ground is hard on paving stone. Across most of the city the soil is clay, which holds water and heaves when it freezes, so a driveway in Millcroft or Palmer laid on a thin base will be lifting at the edges within a few winters. We excavate deeper than the stone needs, lay and compact a graded gravel base in lifts, and lock the joints with polymeric sand. Closer to the lake in Roseland, Shoreacres and Aldershot the soil is sandier and drains better, so the base depth and edge restraint change with it.

North of the QEW the lots start to slope toward the escarpment. In Tyandaga, Mountainside and Brant Hills the grading is often the whole job: a driveway or patio has to shed water across the slope and away from the house, which may mean a retaining wall, a step down, or a drain run along the low edge. Properties near the Niagara Escarpment may have conservation-authority review for grading, so we check before changing the land. Burlington also regulates removal of larger private trees, and the big lots in Aldershot and Roseland have many of them, so we confirm before excavating near roots.

In Orchard and Alton Village the request is usually a widened driveway or a back patio on a builder lot where the fill is still settling, so we compact to a proof-rolled grade before laying anything.
