The Latin name, Concretum, has become synonymous throughout
history with strength and durability.
Ancient traces of the tough and durable material known as concrete
date back 7000 years and have been discovered in some of the most
famous buildings from the Roman Empire. Yet, despite this early
evidence, somehow the art of making concrete was lost. It wasn't until
the 17th century that concrete was rediscovered and once more
became one of the most common construction materials of all times.
With special grinding machines and diamond tools,
World of Decorative Concrete, grind and polish concrete floors to
remove the surface paste and expose the stronger concrete beneath.
This revolutionary flooring concept converts concrete into more than
just strong and hardwearing.
The result of this process is a stronger, more durable, shiny and
beautiful floor.

When grinding concrete floors, the weaker concrete outer skin is
removed and the stronger and harder concrete surface is exposed.
Concrete floor grinding and polishing is created by mechanical
processing of the concrete surface by means of grinding and refining
the surface using diamond-encrusted abrasive tools until a desired
finish is achieved.
This process takes some time and only a qualified specialist in
concrete grinding and polishing, such as World of Decorative
Concrete, should ideally be appointed to install a ground and
polished concrete floor.

To achieve the standard and quality of concrete grinding and polishing to
the standard displayed on World of Decorative Concrete's webpages,
full knowledge of the process of concrete and the proper execution of the
process, along with the best quality machines and grinding tools, are
required.
There may be a number of companies and people in the grinding and
polishing industry. However, it’s always a fair recommendation to inspect
actual work done and to obtain references from companies/individuals
who made use of these companies, and to make sure that displays and
pictures of work they use for marketing and presentations are actually
their own and done by themselves.
World of Decorative Concrete’s products can be viewed across most
of southern Africa. One of our greatest achievements has been the
successful completion of 63 000 m2 concrete flooring and the
manufacturing of all the hard landscape items at the Moses Mabhida
World Cup Soccer Stadium in Durban.
Can anyone grind and polish concrete?

When ground and polished concrete floors are been kept clean and dry, these concrete
floors are generally no more slippery than normal plain power floated concrete floors.
In fact, it tends to be less slippery than waxed linoleum floors, polished marble and
epoxy floors.
According to the ADA, OSHA and ASTM guidelines, ground and polished floor
surfaces shall be considered slip resistant if the measured static coefficient of
friction is a minimum of 0.5 when tested in accordance with either ASTM C-1028
(field laboratory test) or ASTM D-2047 (laboratory test) methods.
The results were as follow:
Dry Floor: High gloss polished floor finished with a 3000 grit resin diamond- 0.7
averages of multiple readings, meaning it EXCEEDS the OSHA standards by 40%.
Wet Floor: High gloss polished floor finished with a 3000 grit resin diamond- 0.61
averages of multiple readings, meaning it EXCEEDS the OSHA standards by 22%.
There are other ways of finishing of a ground and polished concrete surface by means
of, a non-slip sealer and or by applying WODC’s own designed special surface
technique.
When used externally and or a Client wants that extra peace of mind regarding safety,
please consult with World of Decorative Concrete.

World of Decorative Concrete uses high tech machinery,
specialized diamond tooling and employs unique techniques
in which we are thoroughly experienced.
This superior application, special process and knowledge of
concrete has been fine-tuned to produce magnificent
concrete floors, unequalled in the industry.
Please note: Quality ground and polished concrete floors is
not simply by exposing the aggregate in the concrete mix and
then applying a sealer. This finished product will never
achieve the brilliance nor be as long-lasting as true ground
and polished concrete floors.

To grind and polish a concrete floor, the actual grinding and polishing
determines 20% of the final outcome. The other 80% is determined by the
placing of the concrete and also the type of concrete chosen.
It is very important that the client understands, that the final end result and
the look and feel the client wants to achieve, is been influenced by the
method, the type of product and the type of grinding and polishing process.
The Artevia Polished by Lafarge has a different look than the Terra Floor
Overlay. The process and method of application, the materials ext. are all
different for the above two polished concrete systems, namely Artevia
Polished by Lafarge and the Terra Floor Overlay.
It is very important that the client pays close attention and examines the
following:
Will the end product always deliver the
same result?

occurs with the final result, the placing of the concrete was the underlying
cause for the unsatisfactory end result..

To guarantee an acceptable end result, the concrete mix and placing of
the concrete must be strictly controlled and a high-level supervision must
be maintained throughout the process.
Please call World of Decorative Concrete in this regard.

The answer is a definite NO! This product was self-engineered by World
of Decorative Concrete. Only our employed, well trained staff or well-
trained sub-contractors, approved by us, are allowed to install, grind and
polish a Terra Floor.
Can a Terra Floor system be installed and ground and
polished by anyone?

Flatness of a Ground and Polished PMC Terra Floor
The substrate below will determine the flatness of the floor. Due to the fact that a
Terra-Floor is only a 12-15mm overlay and that clients want to see a good
aggregate distribution, variation in the flatness of the floor may occur. The average
variation is +- 5mm over a length of 3m.
Flatness of a Ground and Polished Artevia Polished Concrete Floor
Clients usually choose their Artevia Polished Floor based on concrete samples
which are normally manufactured under controlled conditions and not based on
pump mixes. Where concrete is pumped on site, the aggregate can be up to 20%
less than in the sample supplied.
In small or difficult areas where it is not financially viable to pump the concrete,
and where one needs to discharge and place the concrete by hand,
the end result to achieve a flat floor can be difficult. The average variation is
+- 5mm over a length of 3m.
Will the floor be super flat and what about levels?
![Page 35: WODC Grinding and Polishing Specification...2016/01/05 · 4 Stage Concrete Grinding and Seal. 1stStage light expose the aggregate 2ndGrinding 3rdGrinding 4thGrinding 2mm. Must be](https://reader036.vdocument.in/reader036/viewer/2022090810/611c5b3f5ca7c27d0f632b45/html5/thumbnails/35.jpg)
For both a Terra Floor and an Artevia Polished Floor, it is the responsibility
of the main contractor to issue World of Decorative Concrete with the final
floor levels.
Where levels are a problem on site, it is very important to consult with all
parties involved, prior to the placement of a PMC Terra Floor or an Artevia
Polished Concrete Floor, to resolve matters.
It is not the responsibility of World of Decorative Concrete to address levels
that was ignored during the initial concrete casting process by others.
World of Decorative Concrete do not correct levels and falls afterwards on
already casted concrete floors by means of grinding.
Please note that World of Decorative Concrete only removes a maximum of
4mm-5mm from the top surface of the concrete during the 7 stage grinding
and polishing process to achieve a high gloss polished look.
