learning the basics of home septic systems

A septic system is something that is easily forgotten until something goes horribly wrong. What should you avoid running down your kitchen sink? Is one type of toilet paper safer to use than another? How often does your septic tank really need to be cleaned? These were just some of the questions that I had about my septic tank after it had backed up and filled my yard with raw sewage. Since then, I have spent hours researching septic systems so that I would not have to go through that again. I have developed my website to make learning about septic systems a little easier for others like me.

What Asphalt Sealant Should I Use?

Matthew Young

Your driveway deserves the best from you. That's why, approximately once every three years, you should reseal your asphalt driveway. Resealing your driveway is not only aesthetically demanding – it makes your driveway look as good as new, many times, but it also increases the lifespan of your asphalt driveway, ensuring that it is with your family for many years to come. There is a question that demands an answer, however: which sort of asphalt sealant should you use? This article will serve to answer that question for you by examining 3 types of asphalt sealant: coal tar emulsion, asphalt emulsion, and oil based asphalt sealer.

Coal Tar Emulsion

Most asphalt sealants consist of the same admixture of water, latex, clay fillers, additives and polymer. However, there is usually one wild card ingredient that tends to mix things up a bit. In this case, it is coal tar.

Coal tar emulsion is a water-based sealant, much like asphalt emulsion, which will be discussed later. The fact of the matter is, hands down, coal tar emulsion is the most effective sealant that is available on the market today. This is not to say that other methods are ineffective, but coal tar emulsion does a perfect job at sealing your asphalt driveway and making sure that it is water resistant, tight, and ready to brave the elements.

Having said this, let it be known that coal tar emulsion can pose a significant threat to you and your family's health, according to recent studies. Coal tar emulsion is now well known as being a heavy carrier of polycyclic aromatic hydrocarbons. This is basically fallout from the creation of the admixture of coal tar emulsion and is a toxic carcinogen. PAHs have been known to find their way into the soil and homes of those who use them regularly on their asphalt driveways.

Asphalt Emulsion

Asphalt emulsion is a well-known alternative to coal tar emulsion (although some forms of asphalt emulsion contain trace drops of coal tar). Asphalt emulsion is the same admixture as coal tar emulsion uses, although in coal tar's place, it uses droplets of asphalt that are suspended in water.

This method is somewhat less effective than coal tar emulsion, though not markedly so. Asphalt emulsion works by binding itself to the asphalt that is already in place on the driveway. It is an attempt to bond new asphalt to old asphalt, which should, in theory, create the appearance of a perfectly united source of asphalt.

In reality, however, this does not seem to work as well. The fact of the matter is, asphalt emulsion, when molded to already existing asphalt, actually creates a disjunctive look, with the new asphalt standing out against the backdrop of the older asphalt that is already in place.

Oil Based Asphalt Sealer

Water based asphalt emulsions are not the only sealant game in town. Oil based asphalt sealants are becoming quite popular these days. They do not carry the same level of toxicity that coal tar emulsions do, and tend to be far more effective than the water based asphalt emulsion. The oil based asphalt sealant does the trick that the water based alternative tries its best to accomplish: it meshes the new with the old. The oil-based sealant is able to seep into the cracks of your asphalt, and fill them in, which creates a much more robust and coherent look. Oil based asphalt sealant, to the naked eye, actually will make your driveway look like new.

When it comes to sealing your driveway, you want the best for you and your family. Hopefully, this brief article has given you a bit of insight into the right decision to make regarding sealing your asphalt driveway.
