Routing & Hot Crack Sealing in Minneapolis, MN

Asphalt is bound to crack. The natural shifting of the ground is constantly putting pressure on your asphalt, making it expand and contract, causing cracks. This allows moisture to penetrate the base layer of the asphalt and break down its structure. The freeze/thaw cycle here in the Twin Cities only compounds this problem. Without professional intervention, it can result in potholes and large cracks, creating an unsafe environment for vehicles and pedestrians.

Crack sealing is the first major step in structural maintenance for your asphalt. Completed early, routing and hot crack sealing will prevent moisture and other substances from penetrating the asphalt and will help extend its lifespan.

How Do We Do It?

The process of crack sealing is quite simple.

First, we rout the existing cracks to create a clean-cut reservoir which aids in effective bonding and proper application of the sealant. Routing a crack before sealing it allows the rubber in the crack to expand and contract with Minnesota’s severe temperature fluctuations and the ground’s movement.

Next, the crack is cleaned out using high-pressured air to ensure bonding between the pavement and crack sealant. Gopher State Sealcoat uses Mn/DOT Spec 3723 rubber sealants— the same product used on highways. We will use either a bander or a melter wand to apply the sealant, depending on the particular commercial project. Once the hot sealant cools it may naturally settle.

Over time, cracks may need to be touched up. However, routed cracks cannot be routed again— only refilled. This is why, with our process, we ensure the cracks in your commercial asphalt are repaired properly the first time.

Routing and hot crack sealing can extend the life of your Minneapolis property’s asphalt and save you from costly replacement. For more information or for a free estimate, contact Gopher State Sealcoat today!
