Grantex's pre-cast concrete aggregates are specifically suited for architectural pre-cast applications. Our materials are used in architectural cladding panels, facade elements, exposed aggregate feature panels and decorative pre-cast components for both commercial and residential buildings. The precision grading and natural colour options of our aggregates make them particularly suited for exposed aggregate finishes where aesthetic appeal and consistency are essential.

Grantex supplies a range of aggregates specifically for architectural pre-cast concrete, each offering distinct aesthetic and performance characteristics.

Our granite range, including Green Granite, Red Granite, and Silver Grey Granite, provides natural colour variation and durability for exposed aggregate finishes and architectural panels. Black Basalt delivers high strength and a striking dark finish, while Polar White and White Dolomite offer bright, clean aesthetics for contemporary designs. Trent Pea provides a natural, rounded aggregate option and our specialist sands (Chempure 60 and Premium Silica Sand) contribute to workability and finish quality. The choice of aggregate depends on your desired aesthetic finish, colour palette and specific architectural requirements.

We maintain strict control over our specialist aggregates processing. Our material is handled in our state-of-the-art UK production facilities, where our aggregates are carefully washed, screened and dried where applicable, to meet the specific requirements of pre-cast concrete applications. This meticulous focus on processing delivers a clean, consistent and reliable aggregate, essential for achieving excellent and predictable results in the final product.

Sustainability is at the heart of our business as we work toward becoming a carbon-neutral company by 2030. Our pre-cast concrete aggregates are ethically sourced, processed via solar-powered operations where possible and packaged into eco-friendly bags.
