Sealcoating in Austin TX


What is Sealcoating?

Sealcoating is the process of applying a coal tar emulsion over an asphalt pavement.

What does it do?

Sealcoat protects your asphalt from the damaging effects of the environment, including moisture and ultraviolet oxidation.  

Why do you need sealcoat on your parking lot?

There are many benefits to sealcoating the asphalt to your driveway or parking lot. Think of sealcoating more of as a preventative maintenance for your diveway or parking lot. 

  • Sealcoating the asphalt, seals the small cracks that can turn into large cracks and prevents water from seeping down to the base material. 
  • The dark black color of newly applied sealcoat improves the appearance of new and old asphalt, making your driveway or parking lot look near brand new. 
  • Another benefit of sealcoating, is that it helps protect the asphalt from the sun as well as the harmful effects of chemical spills such as oil and gasoline. 
  • Sealcoating acts as a waterproofing agent, minimizing the rate at which water enters the asphalt. Sealcoating asphalt prevents the seepage of water and moisture from rain and snow, thus preventing damage from freeze thaw cycles which is a common reason your driveway or parking lot begins forming cracks or even worse, alligator cracks.
  • Sealcoating provides an attractive black surface that is ideal for painting lines and other markers on parking lots. Sealcoat is a dark, black colored matarial and when applied to asphalt, it helps attract more heat from the sun. The hotter the sealcoating on the asphalt gets, the more pliable it becomes, which helps it to withstand traffic without cracking. 
  • Sealcoating fills surface voids, which reduces exposure to oxygen and UV rays and reduces the depth to which oil or gas can penetrate the asphalt. 
  • It acts as a waterproofing agent, minimizing the rate at which water enters the asphalt of your driveway or parking lot. The intrusion of moisture into asphalt accelerates its deterioration.
  •  Sealcoating seals the asphalt pavement, preventing the oxidation and erosion of the top layer and replaces fine particles lost from the asphalt surface due to oxidation on older pavements.
  • Sealcoating preserves asphalt for pennies per square foot, verses costly asphalt repairs. 

Our Procedure

  1. First, TexAsphalt thoroughly cleans your pavement using a combination of wire brushes, power brooms, power blowers and where necessary, power washers. We also, where appropriate, trim the grassed edges of your pavement, removing the grass and dirt, allowing us to seal the edges of your pavement where deterioration usually starts.
  2. After the pavement is thoroughly cleaned, we start the seal coating process. Our process involves applying an emulsion based seal coat material with 3 lbs of sand per gallon added to the emulsion. We squeegee brush the edges with sealcoat to prevent over spray onto concrete. We apply the seal coat in two coats. The first coat is applied by the spray method. Once the first coat is dried we apply a second coat which is also sprayed on.
    1. Where appropriate, to prevent staining of those surfaces, small brushes are used to cut-in adjacent to curbs, aprons, sidewalks, etc. Please note: where cutting in is necessary and appropriate, you may notice a darker shade resulting from additional material in those areas. The shading is unavoidable; but in time, these areas will blend in with the rest of your driveway.
    2. Heavily alligatored areas are double seal coated or treated with a special, very thick material to help cover and stabilize those areas where your driveway has a base failure. This is not a permanent solution, but a time buying procedure which cannot be guaranteed.
  3. Once the seal coat process is finished we barricade your driveway(s) with caution tape or construction cones for 24-48 hours
