Concrete is composed of coarse aggregate, fine aggregate, cement powder, and water. Properly mixed and installed it can last for many years. Concrete is the most widely used product in the world, second only to naturally occurring water. Concrete has a very high compressive strength and is commonly combined with rebar or similar product to give additional tensile strength. Concrete will continue to harden for years, even decades after it is mixed. But its most important curing time is within the first 4 weeks, where it will gain 90% of its strength. Proper installation is a crucial role in maintaining the ability to cure to design strength.
Depending on a customers preference, concrete can add significant cosmetic and functionality to any driveway and landscape. With many color and surface pattern options to enhance the conventional broomed- grey finish, the aesthetic possibilities are endless.
Pros of Concrete:
- Does not break down from petroleum spills or drips from vehicles
- Is not structurally affected by temperature changes
- Has a long life expectancy when properly maintained
- Large array of colours and designs available.
Cons of Concrete:
- Is not easily repaired if damaged, most cases it cannot be “patched”
- Removal of old concrete is more labour or machine intensive to break up
- Higher labour costs in preparing, including forming and rebar installation
- Higher material cost due to the complex chemical cement powder needed.
- Is very dense and rigid and does not allow for any movement
- Has a high cost recycling process
