How do I tie my Ottawa paver driveway into the garage threshold?

The transition between your interlock paver driveway and garage threshold requires careful planning for proper drainage, structural support, and a clean finished appearance. This connection point is critical because it handles heavy vehicle loads while managing water runoff and accommodating the height difference between your pavers and garage floor.

Proper Height and Slope Management

Your paver surface should sit approximately 25-50mm below your garage threshold to create positive drainage away from the garage. This prevents water from flowing into your garage during heavy rains or snowmelt. The pavers should slope away from the garage at a minimum 2% grade (20mm drop per metre). In Ottawa's climate, this drainage is absolutely critical — standing water at the garage entrance will freeze into a dangerous ice sheet and can cause frost damage to both the pavers and garage foundation.

The garage threshold itself is typically a concrete beam or steel angle that spans the garage opening. Your paver contractor will need to cut pavers precisely to fit against this threshold, leaving a small expansion gap (5-10mm) that gets filled with polymeric sand or flexible sealant. This gap accommodates thermal movement — remember that Ottawa's 60-degree temperature swings cause significant expansion and contraction in both concrete and pavers.

Base Preparation at the Transition

The area immediately adjacent to your garage requires extra attention to base preparation. The granular base must be properly compacted right up to the garage foundation wall, and you may need additional base depth here to handle the concentrated wheel loads as vehicles enter and exit. Many contractors install a concrete edge beam or haunching along the garage threshold to provide extra structural support for the border pavers.

Managing the Joint and Sealing

The joint between your pavers and garage threshold should be sealed with a high-quality polyurethane sealant that remains flexible through freeze-thaw cycles. This prevents water infiltration that could undermine the base or cause frost heaving. In Ottawa, this sealant typically needs renewal every 3-5 years as freeze-thaw cycling breaks down even the best products.

Some contractors prefer to install a narrow concrete strip (100-150mm wide) directly against the garage threshold, then butt the pavers against this concrete strip. This creates a more stable transition and makes it easier to achieve the proper slope and height relationship.

Drainage Considerations

If your driveway slopes toward the garage, you'll need to install a drainage solution — typically a linear drain (trench drain) across the driveway 1-2 metres from the garage entrance. This collects water before it reaches the garage and directs it to storm drains or swales. Without proper drainage, Ottawa's heavy spring runoff and summer downpours will flood your garage.

When to Hire a Professional

This transition requires precise measurement, cutting, and grading that's best handled by an experienced interlock contractor. The height relationships, drainage slopes, and structural requirements at this junction are critical to long-term performance. A poorly executed garage transition is one of the most common failure points in Ottawa paver driveways, leading to settling, water infiltration, and ice buildup problems that are expensive to fix later.
