Importance of Sealing Concrete: Sealing concrete surfaces can help protect against damage from moisture, staining, and other factors that can cause deterioration over time. It can also enhance the appearance of the surface and make it easier to clean and maintain.
Exposed aggregate is a popular decorative concrete technique that involves removing the top layer of concrete to reveal the natural aggregate underneath. This creates a textured surface that is both visually appealing and slip-resistant.
Excavation is typically done with the use of heavy machineries, such as excavators or Skidsteer bobcats, as well as hand tools like shovels and picks. Proper excavation techniques are important for ensuring the stability and longevity of the finished concrete structure, as well as minimizing the risk of accidents or damage to surrounding structures.
The subgrade is the foundation layer, made up of compacted soil, crusher dust or road base aggregate. Its quality directly affects the overall performance of the concrete structure, as well as its longevity and durability. Evaluating the subgrade's properties, such as its strength, stiffness, and moisture content is crucial before constructing a pavement on top of it. Proper preparation and improvement of the subgrade can prevent concrete distress, such as rutting and cracking, which can lead to expensive maintenance and repairs. In summary, the subgrade plays a critical role in ensuring the long-term performance of a concrete system, and it is essential to give it due consideration during construction.
