Why Concrete?
Concrete
is one of the oldest composite building materials in the world. Made of
natural ingredients, concrete is environmentally sound, economical to
manufacture and is relatively energy efficient to produce. (compared to
other structural building materials) Examples of its durability span the
globe, from Greece to the Americas. Some profess the Great Pyramids of Egypt were made of poured concrete.
Of all its
attributes; strength, rigidity, durability, and watertightness, it's
most miraculous characteristic is its ability to be molded into any
shape. This is why we see concrete used in so many applications. From
building blocks to bridges and towers, from massive dams to counter-tops
and sail boats. Is it any wonder that it is the ideal and obvious
choice for water and waste-water containment?
Ideal, not only
by how it performs, but because of a long standing confidence and
history of use. In many cases the value of the function of the product
far exceeds the initial cost of the product. If a septic tank fails and
causes the treatment system to malfunction, the repercussions are far
greater than the price of the tank. If a water cistern allows
contaminates to infiltrate, the outcome could be catastrophic. This is
why warrantees based on "replacement cost" and "money-back guarantees",
claims made by competitive products, are meaningless. The designer,
specifier and end-user need the assurance that a product has a known
track-record, a history of success, before the purchase is made.
Concrete products are used throughout the world. Contractors know how to
use them, regulators and specifiers trust them. They have a reputation
that spans history.
- Can the same be said about polyethelyene or fiberglass?
- Have you ever seen a 100 year old piece of plastic?
But what about
bad concrete? We've all seen or heard of examples of poor workmanship.
Concrete curbs deteriorating in the winter, house foundations with
settling cracks, leaking septic tanks. Sometimes it's extenuating
circumstances like poor installation or maintenance. Sometimes it's
poorly made concrete. Concrete production isn't about a wheelbarrow and a
shovel anymore. Today's manufacturers use properly specified materials,
computerized batching, a range of chemical admixtures and controlled
production environments to produce consistently high quality, high
strength concrete. The concrete manufactured today is better than ever.
Even that which was produced just 20 years ago.
