COMMERCIAL CRACK SEALING
We deliver crack filling and joint sealing services—truly the first line of defense against the degradation and eventual failure of pavement. Cracks allow moisture penetration from rain, snow, salt and ice, which erodes the base of your parking lot. As these harmful substances penetrate the subbase of the pavement, the cracks widen and eventually cause potholes.
Crack sealing these gaps effectively stops the seepage of harmful substances and prolongs the life of your pavement. Proper crack sealing prevents issues from spreading while doubling the pavement’s service life. Proactive maintenance in the beginning stages of deterioration saves businesses money by delaying expensive pavement work.
Crack Sealing Process
- The cracks are routed to make uniform in depth and form a reservoir for the sealant
- Obstructions, such as vegetation, are removed from the cracks with a wire-wheel
- Hot-applied rubberized joint sealant is applied to fill the cracks
* Crack routing is necessary to ensure proper bonding. High-traffic areas are strongly encouraged for routing as long as the cracks have not already been sealed. Repair methods depend on budget, pavement downtime, and crack type. A protective reservoir for the sealant material is created through crack routing.
Advantages of Crack Sealing
- Preventative – Crack sealer is designed to seal cracks and joints from moisture.
- Superior Material – Pavement Solutions uses a hot sealer when crack sealing. Cold sealer has a tendency to pop out of the crack from temperature changes.
- Elasticity – Crack sealant moves along with the crack’s thermal movements.
Types of Cracks
ALLIGATOR
Total structural failure. These usually start off as small longitudinal cracks in the wheel-path, and end up as alligator cracks after distress. Flexible asphalt becomes less tolerable to vertical deflections over time. Tension is created, resulting in alligator-type-cracking.
Caused by: Overall weak surface, base, and/or sub grade. A surface or base that is too thin. Poor drainage. OR all of the above.
SLIPPAGE
Crescent-shaped cracks/tears in the top surface layers of the asphalt, where new materials have slipped over the underlying asphalt.
Caused by: A poor bonding between the layers. Often because of dirt, oil, and debris not allowing the layers to adhere to each other. Also may be from not using a prime-coat wasn’t used to bond the asphalt to the stone underneath; and/or a tack-coat wasn’t used to develop the bond between asphalt layers.
EDGE
Parallel-appearing cracks that are near the pavement’s edge. Cracks that appear, and travel, parallel to the edges of pavement surfaces. If left ignored, the underlying base materials will begin to settle and become very weak.
Caused by: Poor drainage conditions, a weak support system at the edge of pavement, heavy traffic, and too much vegetation.
BLOCK
Large cracking that forms a square/rectangular pattern, intersecting at approximately 90 degrees.
Caused by: shrinkage of the asphalt pavement from temperature cycles.
JOINT REFLECTION
Cracks that form on a flexible pavement overlay of a rigid pavement, like asphalt over the top of concrete. Joint cracks are created from improperly bonded joints.
Caused by: improperly bonded joints
LONGITUDINAL
(Also known as linear cracking) Cracks that are parallel to the center line of the pavement.
Caused by: Pavement fatigue, reflective cracks, and/or construction of the joints.
