The Rhombus Quality

We work closely with customers to ensure that we consistently deliver products per their requirements and above their expectations. We also ensure every raw material and final products are rigorously tested at independent laboratories to meet international standards.
In order to give our customers exceptional concrete strength and durability, we manufactured rock sand which has proven to give better test results than riversand
The renowned Rhombus quality is also guaranteed by our team of highly qualified and massively experienced technical team who assure quality at the batching plant and on the construction site. They are also always at hand to train all our customers on the best methods of curing and everything else they need to know about concrete.

Efficient Delivery

We have invested in an adequate number of the latest delivery trucks so that our products are delivered to our customers within 48 hours of confirming an order.

They come with pumps that have a capacity of pumping over 2000m³ – making it possible to cover a mega project and to seamlessly cast at multiple sites without disappointing or rescheduling with any customer.

Customer Support

We have a dedicated customer support team to walk with our customers through every stage of the customer journey. For starters, the marketing team reaches out to our prospects with everything they need to make informed buying decisions. Then the technical sales team does a pre-cast site visit to survey and agree on the best organization for an efficient pour.

On casting day, we have representatives to coordinate concrete delivery and ensure seamless casting and thereafter, our support team avails themselves to customers and offers them timely advice on cost-effective, efficient and sustainable application of our products.

It is standard practice for us to continually visit our customers and conduct surveys to get feedback on areas of improvement.
