If your home features a driveway made from concrete, you need to seal the slab early on to avoid potentially costly, disastrous, and unfixable problems in the future. Many driveways are made from asphalt, which means the use of a concrete sealer is not the appropriate choice. However, more driveways are made from concrete whether a traditional gray slab or another variant of concrete, such as pavers which makes a concrete sealer imperative.
Concrete sealers help protect concrete slabs from a variety of dangers. Concrete, while extremely strong, is also very porous. The high level of porosity is due to its mixing process: water, Portland cement, and some sort of aggregate, such as sand or gravel, are diligently mixed together to form what will become concrete. Then, the mixture is properly poured and cured until it fully dries to its full strength. However, a natural by-product of this process is the creation of a large number of microscopic pores and hairline cracks that extend throughout the slab.
These pores and cracks do not normally threaten a concrete slabs structural integrity. However, the weather, human error, and the elements those ever-present and unavoidable threats can reduce your seemingly strong and solid concrete slab to a crumbling disaster. This is especially true for a concrete driveway which is constantly exposed to the elements with nary a break. And if your driveway is in an area that sees snow and ice in the winter, such potential threats as freeze/thaw cycles and excess salt from salted roads can ruin your concrete faster than you would believe.
The best choice for a concrete driveway would be the Siloxa-Tek 8500, Siloxa-Tek 8505 or Siloxa-Tek 8510. The Siloxa-Tek 8500 is a water based water and salt repellent, the Siloxa-Tek 8505 is a water based water, salt and stain repellent and the Siloxa-Tek 8510 is a solvent based water, salt and stain repellent. All three products will protect concrete driveways from spalling, pitting, cracking, corrosion and degradation.
