Similarly, while trains and airplanes provide alternatives to driving between cities, they are often expensive or inconvenient for any number of reasons, causing many Americans to have to take to the roads and vast highway system of the United States.
However, in order for highways to remain as strong and reliable as possible, they need to be well maintained to stand the test of time and the ravages of the elements. For starters, we must ask how does one care for concrete? The best answer to that question is to use a quality concrete sealing product to help protect the highways from the elements, especially constant exposure to the sun, rain, snow, sleet, hail, and ice. As probably the biggest threat to all man-made constructions and creations, weather is an ever present part of life that never goes away, especially for such things as roads and highways that are constantly exposed to the elements.
Therefore, highways certainly need to be protected with a high quality concrete sealer. Once this is accepted, the next question becomes which concrete sealer to use. Concrete sealers come in a wide variety of kinds, each suited to a specific and particular type of project. For a concrete highway, the proper choice would be a silane/siloxane concrete sealer. Silane/siloxane concrete sealers, like the Siloxa-Tek 8510, contain particles of silane and particles of siloxane, which are two different things. The silane particles will penetrate slightly past the surface of the concrete while the siloxane particles will pool on the surface of the concrete to be spread out over the course of the application process. Together, the two types of particles suspeneded in the Siloxa-Tek's solvent-based solution will work in concert to create a hydrophobic barrier that locks out excessive water, as well as other minerals (like salts from trucks in the winter) and staining from oils and greases, from entering the concrete where they can wreak havoc, resulting in potentially costly repairs.
