With everyone battening down the hatches in preparation for fall weather; we thought it would be appropriate to explore one of the many effects from torrential rainfall: hydrostatic water pressure. Hydrostatic water pressure is most common in basements, but its wrath can be seen all over… including your parking lot!

One of the biggest destroyers of asphalt is moisture. When moisture accumulates below the surface it compromises the strength of the stone base and softens the underlying soils. The simplest, most efficient way to solve this problem is with the addition of under-drains – commonly referred to French drains in the industry. How does it work, you ask? Let us explain…

Once the old asphalt is removed we dig a trench, usually to a depth of 24”, and install fabric-wrapped perforated pipe. The trench is then filled with open-grated stone. This allows the ground water to find its way to the pipe and out from beneath the pavement. Finally, the asphalt surface if replaced. Depending on the location of the French drain, porous asphalt may be installed to eliminate water ponding issues as well.

French drains can—if properly installed—extend the overall lifespan of your asphalt.

As leaders in the St. Louis asphalt industry, we feel it is our duty to provide more than just great paving solutions, but knowledge that everyone can utilize in preserving their parking lot. While asphalt is tough in nature, it will develop cracks over time. Unfortunately cracks are completely unavoidable; however they can be easily repaired.

In this blog entry, we explain exactly what goes into the repairing process.

#1 Clean the Surface: It is extremely important we clean any loose debris that sits within the cracks. Once we loosen all the broken asphalt using a heat lance or abrasion wheel, we will go over the infected area with a high pressure blower or power broom to remove any loose material.

#2 Fill the Cracks: We use hot applied rubberized crackfill material specifically designed for cracks in asphalt surfaces. This type of material is heated in large double wall burners and is usually only available to professionals in the asphalt industry. The proper material and equipment makes all the difference in preserving your asphalt surface.

#3 Let Dry: Crackfilled areas can be opened to traffic in a relatively short period of time. We do not recommend applying crackfill material in current weather conditions as the material will not set up properly and will remain “tacky” to foot and vehicle traffic. One of our pavement professionals will explain the necessary drying period before the project is completed.
