Crack Repair

Is your parking lot showing signs of wear or small cracks?  Consider the correct asphalt maintenance plan before it is too late.  Valley Sweeping of Rapid City can help!  At Valley Sweeping, we use high quality, commercial grade sealer products that are an economical  material mainly for use on parking lots.  Our crack sealer materials are a high quality hot application crack filling material, that are idea for all crack filling applications.

We use special crack seal applicators that apply a hot rubberized crack filler that expands and seals when drying and setting.  This process has been tested and has proven its performance in the most demanding of conditions.  In fact, our hot crack sealing process is almost identical to the process used by most local municipal, state, and government agencies on highways, road ways, parking lots, and airports.  The only difference is we utilize smaller more economical equipment to save you money.

Seal Coating


Valley Sweeping of Rapid City can seal your asphalt and save you a ton of money from costly repairs down the road.  Did you know that it is recommended that you seal coat your asphalt parking lot or driveway every 2 to 5 years?  The main reason to apply new seal coat to your lot or driveway is to protect your asphalt surface from expensive damage.  Sealcoating is your best asphalt maintenance plan to keep your asphalt safe from the harsh South Dakota seasons.

Seal Coating a parking lot or a driveway is achieved by placing a liquid emulsion (sealant) over the existing asphalt base. This emulsion is sprayed on the surface, and maneuvered around the edges with a rubber squeegee (if needed) to seal and protect the asphalt surface of your lot or driveway.

Seal coating your asphalt is like wearing rubber gloves on your hands.  It protects and seals the asphalt pavement, thus preventing the oxidation and erosion of the top layer of asphalt.  Oxidation of the asphalt surface causes it to dry and become brittle, and eventually leads to the erosion of the top layer and exposes the larger stones and small cracks in the surface.  Once the top layer has been broken down, water penetrates into the small pits and cracks.  Eventually these cracks grow over time and water penetrates to the base of the pavement.  The primary cause of asphalt deterioration is the deep penetration of water.  Water  freezes and expands the cracks even further, as well as softens and erodes the base material below the asphalt.  Once the base material begins to move and settle, additional cracks and potholes in the asphalt occur, requiring costly maintenance.
