Asphalt Contractor in Newmarket - Right Seal Inc

Properties near the waterfront face a humid lakefront microclimate that causes frequent dew formation, heavy rain runoff, and damp winter conditions. This constant moisture speeds up the oxidation and breaking down of the asphalt’s oil binders. When this dampness is combined with rapid freeze-thaw cycles, water trapped inside minor surface pores expands quickly, cracking the asphalt open much faster than it would in inland regions.

Pouring sealant directly into a raw, narrow crack creates only a thin surface layer that can easily peel up under heavy traffic or snowplow blades. Mechanical routing carves out a clean, uniform rectangular channel. This shape provides a much wider surface area for the hot rubberized compound to bond with, creating a thick, flexible joint that handles seasonal expansion and contraction without cracking open again.

Storm drains and catch basins are built from heavy, rigid concrete blocks anchored deep in the ground, whereas the surrounding parking lot is flexible asphalt. Over time, heavy vehicle traffic and water leaking through worn seams 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.

High-durability traffic paints dry quickly, typically within 30 to 45 minutes under normal conditions. However, to prevent heavy vehicles from tracking wet paint across the lot and to ensure the markings form a tough, long-lasting bond with the substrate, it is best to keep vehicles off the fresh lines for at least 2 to 3 hours after application.

Applying a hot rubberized sealant over loose sand, dirt, or winter salt residue prevents the compound from sticking directly to the solid asphalt walls. The sealant ends up bonding with the loose dirt instead, causing it to tear away from the crack during the next heavy rain or cold snap. Deep power sweeping cleans out this loose debris, ensuring a strong, permanent bond.
