Crack Sealing
Stop Water. Stop Damage.
At BorderLines, we dedicate the proper time and care to effectively seal cracks so your paved property lasts for years to come. Regular crack sealing is the most important thing you can do in preventative pavement maintenance. Left untreated, water and moisture trapped in cracks cause erosion that jeopardizes the integrity of the structure and leads to large repair costs.
Why Commercial Crack Sealing Matters
- Keeps water and moisture out of your pavement
- Prevents erosion that jeopardizes structural integrity
- Helps you avoid large repair costs later
- Materials that meet or exceed MnDOT specifications
- Rubber that stays pliable through freeze and thaw cycles
- Black silica sand finish that prevents tracking
Our Commercial Crack Sealing Process
-
1
Clean The Cracks
High-powered blowers and a Crack Jet heat lance remove vegetation and debris from each crack.
-
2
Dry For Adhesion
The heat lance dries the crack to optimize adhesion between the rubber and the pavement.
-
3
Rout Where Recommended
Where recommended, a machine cutter routs along the cracks to make more room between the pavement and rubber.
-
4
Fill At 400°F
Rubber heated to 400°F fills the crack completely so water cannot enter.
-
5
Apply Silica Sand
Black silica sand is applied immediately to prevent tracking while the rubber cures.
