Concrete is an essential material for outdoor features such as balconies, steps, walkways, landings and parking areas. Its durability depends not only on the mix, but also on a range of technical factors that must be addressed from the outset.
Strength (MPa), air entrainment, reinforcement, thickness, base preparation, formwork and curing all directly affect the quality of the result. Poorly installed concrete can crack, settle or deteriorate prematurely.
Here are the essential factors to understand for a lasting project.
MPa (megapascals) measures the compressive strength of concrete. The higher this number, the greater the loads the concrete can support.
The appropriate MPa rating depends directly on the intended use. Unsuitable concrete can lead to premature wear.
In a climate like ours, air entrainment is essential.
Concrete is very strong in compression but weaker in tension. Reinforcement compensates for this weakness.

Typical spacing:
Uses:
Reduces microcracks, but does not always replace steel reinforcement.
Reinforcement must be:
A slab that is too thin almost always leads to cracks.
Thickness must be suited to the intended use and soil conditions.
It all starts beneath the concrete.
Essential steps:
A poor base = settlement and cracks.
Concrete allows a wide variety of shapes and finishes, but they must be properly executed to prevent long-term problems.
Steps are critical areas:
Stresses:

Formwork requires:
An error at this stage affects the entire final result.
Concrete naturally cracks. The goal is to control those cracks.
Concrete does not simply dry; it hardens through a reaction with water.
Proper curing provides:
Some cracks are normal if they are controlled.
They are problematic if they are:
Durable concrete depends on several factors:
Quality depends on more than the concrete itself…
it comes from the entire system and how it is installed.
