What is the best finish for a concrete driveway in NB winters?

The best finish for a concrete driveway in New Brunswick winters is a medium broom finish — a textured surface created by dragging a stiff-bristled broom across the freshly floated concrete. This finish provides the right balance of traction on icy surfaces, durability through 150+ annual freeze-thaw cycles, and ease of maintenance for NB homeowners.

Why broom finish is the NB standard: The texture of a broom finish creates grip for foot traffic and tire traction on icy driveway surfaces — critical in NB from November through March. Smoother finishes like a trowel finish look excellent but become dangerously slippery when wet or icy, which is a serious safety concern for NB winters. The ridges of a broom finish also channel meltwater away from the surface and give ice slightly less purchase compared to a completely flat surface.

Broom direction matters: Broom the surface perpendicular to the direction of travel (across the width of the driveway), not parallel to it. This creates ridges that vehicle tires cross, maximizing grip. Longitudinal brooming (parallel to traffic) provides less benefit for traction.

Finish depth: A light broom creates fine lines and a subtle texture; a heavy broom creates deeper ridges. For NB driveways, a medium broom finish (0.5-1 mm depth) is ideal — deep enough for traction and snow shovel clearance, not so deep that it is difficult to clean or that de-icing sand accumulates in the grooves.

Exposed aggregate: a premium but durable option. An exposed aggregate finish — where the surface cement paste is washed away while the concrete is still green to reveal the decorative aggregate beneath — is an excellent NB driveway choice. The natural stone aggregate provides outstanding traction and the texture is inherently non-slip. It costs $2-$4 per square foot more than a standard broom finish ($10-$16 per square foot installed) but is extremely durable under NB freeze-thaw conditions when the proper air-entrained mix is used. Many Moncton, Fredericton, and Saint John homeowners choose exposed aggregate for its traction and curb appeal combination.

Stamped concrete for driveways: Stamped concrete is visually appealing but every pattern involves textures with peaks and valleys. Some stamped patterns retain more ice than a broom finish. If you are considering stamped concrete for your NB driveway, discuss traction and maintenance with your contractor — and budget for regular sealing (annually for stamped concrete versus every 2-3 years for broom or exposed aggregate).

Avoid smooth trowel finishes on any NB exterior concrete surface that pedestrians or vehicles must use in winter. Save the smooth finish for interior garage floors and basement slabs, where a sealer and grip additive can address traction concerns.
