Asphalt Maintenance (Driveway sealing & Crack Repair)

---

Seal coating asphalt is the process of applying a liquid product over an existing asphalt pavement in a manner that seals the surface and fills small voids and cracks as protection against the elements. Clean Slate Contracting uses a spray system for better coverage and equal distribution. Left unsealed, sunlight and water will gradually cause asphalt to harden and oxidize, and as it becomes more brittle, cracking can occur. Over the space of a few years, asphalt paving can be seriously damaged if it is not periodically sealed.

In Nova Scotia, the cold and wet climate can reek havoc on asphalt. Sealing can help prevent damage from freezing water as well as salts and chemicals.

Cracks come in all shapes and sizes, and no pavement is immune to cracking. If left untreated, those cracks are only the start of more significant problems, from potholes all the way to sub-base failure. Crack sealing is the process of placing an adhesive sealant (hot rubber) into cracks on the pavement surface, preventing the infiltration of moisture / ice into the pavement. It is a cost-effective pavement preservation treatment that can slow pavement’s deterioration and extend pavement life by three to five years.
