A Word from the Founder

We began with a single honest block…
and built on it a trust that has lasted for decades

Hussein Abu Gafrah
Hussein Abu GafrahFounder of Riyadh Block Factory

“Trust is not bought; it is built, course upon course.”

Dear clients and partners,

In the beginning, this factory was no more than an idea and a determination. Yet from the very first day I believed that craftsmanship is an honour, and that excellence is a right owed to those who place their trust in us — long before it is a distinction to take pride in.

I learned that a promise is a debt, that patience never fails those who keep it, and that our most valuable asset is neither machinery nor yards, but loyal men who have worked with us faithfully, and clients who gave us their trust and became partners and family.

The factory has grown and the circle of those we serve has widened, but the principle remains unchanged: to deliver only what we would accept for ourselves, and to honour every promise we make.

Today, as I watch this trust pass to a new generation, I ask of them what I ask of myself: that honesty remains our foundation, and that we live up to the confidence of everyone who has placed their trust in us.

We promise to remain your first choice for quality and service, and we would be honoured to be part of your upcoming projects.

Delivery on schedule, because your project timeline is our timeline.

Full Accountability

We take responsibility for any defect in our products, without hesitation.

Customer Satisfaction

Continuous follow-up on customer satisfaction with product and service after delivery.

The Journey of a Block

From raw stone
to the walls of your project

  1. 1
    Raw Materials

    Selected aggregates from approved quarries, Portland cement and volcanic stone.

  2. 2
    Automated Mixing

    Electronically weighed proportions for each type, calibrated to achieve the required compressive strength.

  3. 3
    Pressing & Moulding

    Semi-automatic production lines compact each block by vibration and pressure in precision moulds.

  4. 4
    Curing & Drying

    Controlled moistening and drying until the block reaches its design strength.

  5. 5
    Quality Testing

    Samples from every batch are tested in our own laboratory and at accredited independent laboratories.

  6. 6
    Palletising & Packing

    Blocks are stacked and palletised automatically, then secured with plastic strapping.

  7. 7
    Truck Delivery

    Our fleet unloads the blocks wherever you need them — at ground level or on upper floors — on time.

Every block passes through these seven stations
before it carries our name
+35years of experience
+20million blocks per year
+50products across three types
ISOISO 9001 quality management system
Automated Production

Semi-automatic production lines for blocks in every size, with particular care in curing to ensure consistent specifications in every batch.

Delivery Fleet

Crane-equipped trucks deliver the blocks directly to site and unload them exactly where you need them.

On-Site Unloading

Unloading at ground level, on upper floors, rooftops or in basements — in the required quantity, at the required time.

Products

Three block types for every construction application

Start by choosing the type according to the wall: load-bearing or non-load-bearing. Then select the category, size and insulation option from the product card. Standard products are 40 cm long and 20 cm high, and every product has a code to quote when ordering.
