Quality Management

The Company is committed to the manufacturing of high quality cement. At
each stage in the cement production process controlling the chemical
composition is a priority. All our manufacturing facilities are accredited to
Quality Management System ISO 9001:2008.

The consistency of performance of the cement is vital for our customers so the
raw materials, intermediate and final products are regularly tested as part of
the whole cement production process.

Our Quality Management procedures includes:
Careful and accurate analysis Quality Control testing of the

compounds”.

In-House Laboratory Testing
The key to comprehensive quality control is the use of an in-house laboratory.
Having an in-house, state-of-the-art laboratory is absolutely necessary to
manufacture superior quality cement.

Our Quality Control laboratory is a primary component to achieve our
mission of maintaining strict control over every aspect of manufacture and
quality and is an integral piece of our ISO 9001:2008 certification.
Our in-house laboratory allows for timely, accurate, cost-effective testing that
ensures every product, from raw material to finished goods, meets all quality
requirements. Cement is tested before being released for sale. Such stringent
attention to quality control is extremely difficult to accomplish without a
state-of-the-art, in-house laboratory.
