The good, the bad, and the ugly of Asphalt removal methods
Sawcutting
What is Good
-Better than a jackhammer as it does not fracture the under edge.
-Creates a uniform edge.
What is Bad
-Bad for the environment High risk of contaminating the drain system and washing toxic slurry into our streams.
-Edge Sealer fails to adhere This is because of the slurry residue.
-Patches tend to sink around the edge This is a result of water from the slurry disrupting the stone layer beneath.
-Overcuts on edges
Overcuts on edges create fail points on asphalt patches.
Grinding
What is Good
-Extremely fast removal = low impact on tenants.
-Controlled Cut. With depth control capabilities, there is zero chance of a depth change order. Plus, grinding creates the superior uniform edge.
-100% environmentally sound. 100% of the grindings are recycled. Grinding also does not require water, therefore, no water = no toxic slurry!
-100% Integrity of the repair. Dry, clean, and scarified edge for a perfect asphalt to asphalt bond. Edge sealer will bond perfectly to maintain watertight seal.
What is Bad
-Absolutely Nothing!
