Crack Sealing: Preserve Your Pavement in Southern Ontario

Joints or cracks in pavement, if not sealed properly, will allow water, dirt and other foreign materials to enter. As water soaks down through the unsealed cracks, damage will occur through the freezing and thawing cycles. Allowing water to penetrate beneath the joint or crack will also displace the sub-grade, which will cause further cracking and generally deteriorate the traffic surface. Don't wait for the problem to get worse, call Pro Pavement Services Ltd. for crack sealing at your business in Southern Ontario.

Hot-Poured Rubber

The practice of sealing cracks and joints with a hot-poured rubberized sealing compound has been around for many years and is recognized by contractors everywhere for its substantial savings in maintenance costs.

Hot-pour rubberized crack or joint sealing materials are used on highways, public streets, private roadways and parking lots (residential, commercial and industrial), track and bus terminals, traffic loops and airport runways just to name a few. Without an ongoing sealing program, the otherwise durable pavement surface will have its life expectancy dramatically shortened.

Long-Term Savings

Joints or cracks sealed with hot-pour, rubberized material have been proven to outperform cold applied and non-rubberized compounds. Although the initial application of hot-pour materials may cost slightly more, this cost is returned in the added years of pavement life. The growing demand for these products throughout North America and other parts of the world confirms large savings in maintenance.

Application Procedure

Step 1: Routing

The use of routers in cracks or joints ensures cleanliness and superior vertical side walls. This allows for a greater bonding surface.

STEP 2: Crack or Joint Cleaning

After the routing operation is completed, all cracks or joints should be clean, dry and free from any foreign debris. This is achieved with portable air packs with a wind velocity of 340 km/hr.

Step 2(A): Optional Cleaning

This method uses a hot compress air lance, which will both clean and dry the cracks or joints. The heat of the lance will also improve the bond of the hot-poured, rubberized crack sealing material.

Step 3: Material Application

The hot-poured, rubberized material will conform to the latest M.O.T. specifications. The material will be flush with the adjacent pavement or be feathered to prevent damage by snow plows. All material will be applied using pour cones specifically designed to control material flow.

Step 4: Traffic Flow

If necessary, in high traffic areas, a fine dust of talc or Portland cement will be broadcast over sealed areas to prevent tracking.
