Sealcoat

Once new asphalt is applied, the aging process commences. Proper maintenance via crack sealing and sealcoating can inhibit the deterioration process by protecting the surface not only from water and weather, but also petroleum products and debris. These services are vital to protecting your investment by prolonging the life of your asphalt.

Crack Sealing

Crack sealing is important to extending the life of your pavement and can improve its appearance and stability.

Water that penetrates the surface of asphalt shortens the lifespan of pavement. The primary access points into asphalt are the unsightly and unsafe cracks that develop over time.

Hot pour crack sealing is the first step in preventing pavement deterioration by prohibiting water from entering and weakening the base. The process also stops pebbles, sand, and dirt from entering and expanding existing cracks, and it helps preserve the integrity of nearby pavement.

We recommend giving attention to cracks early in their appearance to prevent small problems from becoming larger ones. In many cases, crack sealing can double the life of your pavement and delay the need for an entire resurfacing.

Why Sealcoat?

Sealcoating is also a vital element of your routine pavement management plan. Because it serves as a barrier coat between asphalt surfaces and destructive elements, sealcoating is used to protect pavement surfaces from petroleum products, oxidization, water, and UV rays. It is applied in thin layers onto existing asphalt and consists of either coal tar pitch or asphalt emulsion mixed with inert fillers, water, emulsifying agents, or additives.

WHY SEALCOAT?

Sealcoating functions as a weatherproofing membrane that extends th

e life of your pavement. Without this protection, your asphalt surface can become brittle and be subject to softening, unraveling, or shoving. Keeping potholes and irregularities at bay not only reduces accident liability, but it reduce

s the need for more costly asphalt repairs and premature replacement.

In addition, sealcoating fills and levels

surface irregularities, resulting in a smoother surface from which it is easier to remove loose sand, dirt, and debris during power sweeping. It also creates a barrier to help protect asphalt from the water press

ure and detergents used in the power washing of dumpster enclosures or parking spaces. Should snow or ice accumulate, they are much easier to remove from a smooth surface.

A first impression makes a difference! After the uniform jet-black sealant is applied, pavement surfaces appear regenerated and beautiful, projecting a positive company brand with attention to detail. The raven color also absorbs the sun, which makes the surface pliable, reinforcing its ability to withstand traffic without cracking.

WHY SEALCOAT

Sealcoating also functions as a waterproofing agent, curtailing the volume and rate at which water filters through pavement. Exposed asphalt allows water to permeate more freely, resulting in potential saturation thus contributing to the expansion and contraction of the

pavement (especially in freezing temperatures).

SEALCOATING PREPARATION & APPLICATION

It is important to remember that sealcoating is a maintenance procedure, not a repair. Maladies and failures that currently exist will still be present after the sealcoat material is applied. Therefore, prior to installation, all structural failures and pavement cracks should be repaired, existing potholes should be milled and replaced, and any oil spots should be removed and primed.

For newly-laid asphalt, manufacturers recommend the surface be sealcoated sometime after the 90-day curing process is complete and within twelve months of installation. Thereafter, sealcoat should be applied every two to four years, depending on external factors such as wear patterns, weather conditions, and the weakening of previous applications.

According to the manufacturer, sealcoating should only be performed under the proper weather conditions. Air and pavement temperature should be at least 50 degrees Fahrenheit during sealer application, and there should be no moisture, potential for rain, or freezing temperatures.

Traffic should be prohibited on newly sealed pavement for a minimum of 18 to 36 hours after application to allow for curing time. This time variable will flex depending on the external wind conditions, humidity, sun availability and temperature. Irrigation must be deactivated near the area and washing should be suspended for a period of 48 hours before and after work is completed. If needed, sealcoating can be applied in stages in non-adjacent areas to minimize the disruption to traffic arriving at a facility.
