Asphalt Contractor in Toronto - Right Seal Inc.

High-density urban properties face relentless stop-and-go traffic, delivery trucks, and sharp tire-turning friction. This mechanical stress places immense pressure on flexible asphalt. If the pavement has unsealed micro-cracks, these heavy loads cause deep sub-base flexing. This speeds up fatigue cracking (alligator cracking) and leads to rapid pothole formation if the surface isn’t sealed in time.

Simply pouring sealant over a narrow, un-routed crack creates a thin, fragile surface layer. As freezing temperatures cause the pavement to contract, this thin band lacks the body to stretch and easily tears away. It is also highly vulnerable to getting caught and peeled up by snowplow blades during winter clearing. Routing cuts a deep, square channel that allows for a thicker, tougher cushion of rubberized sealant that handles severe shifting and stays safely below the plow line.

Catch basins are rigid concrete structures, while the parking lot is flexible asphalt. Over time, heavy vehicle traffic and water leaking through worn joints wash away the gravel base supporting the asphalt. This causes the surrounding pavement to sag and collapse, forming dangerous deep drops that require concrete rebuilding and fresh asphalt patching.

No, these two services must be spaced out. Freshly applied asphalt sealcoating contains oils that must cure and dry completely, which usually takes about 24 hours of warm weather. If layout line paint is applied too soon, the underlying sealcoat oils will bleed right through the fresh paint, turning bright white or yellow markings into a muddy, dull grey that quickly loses visibility and flakes off.

Leftover winter sand and salt act like a coarse grinding paste under rotating vehicle tires, constantly wearing down the fine stone aggregates and protective oil binders on the surface of your asphalt. Furthermore, summer rain washes this fine grit directly into open cracks, packing them tight and blocking future hot-pour sealants from bonding with the clean asphalt walls. Thorough spring power sweeping is essential to clear these abrasives away.
