Hello ,
The practical use of asphalt dates to the new stone age or roughly the beginning of settled human history. This naturally occurring material’s properties as a sealant, water proofer, building mortar, and adhesive have served humanity for centuries. Today, most people are familiar with the use
of asphalt in paving and roofing, but part 2 of our Email Series explores other unique uses related to plants and vegetation.
Because asphaltic products are suitable for use both below grade and above ground, they have long been used as a means of minimizing rot and decay due to water seepage. Plant liners are a prime example
of this application. Today, plant liners are often made from recycled paper products that are turned into pulp and molded into form. This is a great use of waste materials, but durability can be an issue. Thankfully there are Asphaltic products that can be used to coat the pulp, enhancing longevity and durability while creating a more robust barrier that deters penetration by the plant’s roots.
Another example
is Terracotta pots and planters which are popular for their natural look, however, the material is very porous and can absorb water and crack when temperatures fluctuate. Many Terracotta pots that are designed for outdoor use are also treated with asphaltic coatings to reduce water absorption and prevent cracking.
