Asphalt Contractor in Woodbridge - Right Seal Inc.

In early spring, the town implements half-load vehicle restrictions on specific roads because the ground is thawing from the top down. Trapped water cannot drain through the frozen soil underneath, leaving the gravel sub-base temporarily soft and saturated. If your commercial parking lot has unsealed cracks during this critical phase, heavy trucks will cause severe sub-base flexing, destroying the asphalt structure and forming instant potholes.

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. Mechanical 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, the joints between these materials can separate due to vehicle weight. If water leaks through these worn joints, it washes away the supporting gravel base around the concrete drain. This causes the adjacent asphalt to sag, crack, and eventually cave in, creating a severe structural hazard that requires concrete masonry rebuilding.

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.
