GRC & Natural Stone FAQ

The questions we hear most about GRC, stone types, installation, timing and maintenance.

How much does a GRC or stone facade cost?
It depends on facade area, level of detail, stone type, finish and building height. Send us your drawings or a photo for an itemised quote.
What is GRC?
Glass fibre reinforced concrete cement, sand, alkali-resistant glass fibres and polymers. Light, rust-free, non-combustible and cast in moulds for fine detail.
How long does a facade take?
It depends on project size. Factory casting runs alongside site preparation to save time, and you get a clear timeline with the quote.
Do you offer a warranty?
Yes, warranty duration and terms are set out in the contract according to the work.
GRC or natural stone?
Natural stone suits large surfaces; GRC is better for columns, cornices and ornaments as it is lighter and more detailed. Most great facades combine both.
Do you work outside Riyadh?
Yes. Our factory is in Riyadh and we supply and install across every region. See service areas.
Can you build a design from a photo?
Yes. We turn the photo into a sized design, make custom moulds and reproduce the detail.
Do you clean and polish old stone?
Yes. We clean, restore, polish and seal stone against water.
Mechanical fixing or adhesive?
Mechanical anchors are the safest for tall facades and heavy stone; adhesive suits low heights. We recommend the right option for your facade.
Marble or granite for a courtyard?
Granite is harder and absorbs less water, so it suits outdoor areas and parking; marble suits interiors.
Can a stained facade look new again?
Usually yes. We clean with the method suited to the stone and then seal it to stop stains returning. See our before & after gallery.
What is GRC?
Glass fibre reinforced concrete cement, sand, alkali-resistant glass fibres and polymer additives, cast in moulds to form precise architectural elements.
Does GRC handle Riyadh heat?
Yes. The glass-fibre reinforcement does not rust, withstands harsh climates, and the material is non-combustible.
Can you make a design from a photo?
Yes. We turn the photo into a design, make a custom mould and cast the elements with the same detail.
Does a mashrabiya give privacy?
Yes. It limits views from outside while letting air and light in and reducing solar heat on windows.
Why is GRC better for domes?
It is far lighter than precast concrete, reducing structural load, and can be formed into precise curves.
