Premier Composite Technologies (PCT) offers unrivalled expertise in advanced composites construction for architectural designs. Our architecture team has undertaken the construction of several projects covering a wide range of high profile complex composite structures.
We understand that pre-fabrication or modularisation is considered to be a key element to aid construction. The best design solutions are achieved from an integrated approach. Our team consists of structural engineers and architects working close cooperation from conception to completion.
The design team is supported by numerous in-house disciplines, ensuring that we have the knowledge base to create complex structures using state of the art technology. Flexible modular designs are constructed and shipped to site for installation.

For architectural UHPC applications, Polyvinyl Alcohol (PVA) fibres are used. The ductile behaviour of this material is a first for concrete, with the capacity to deform and support flexural and tensile loads, even after initial cracking. The use of this material for construction is simplified by the elimination of reinforcing steel and the ability of the material to be virtually self-placing or dry cast.
Architectural UHPC can achieve compressive strengths up to 17,000 psi (117 MPa) and flexural strengths up to 2,900 psi (20 MPa). Due to the material’s superior compressive and flexural properties, the need for passive reinforcing can be eliminated or greatly reduced (depending on the application). It is also highly mouldable and replicates form materials with extreme precision. The superior durability characteristics are due to a combination of fine powders selected for their grain size (maximum 600 micrometre) and chemical reactivity. The net effect is a maximum compactness and a small, disconnected pore structure.
The advantages of UHPC are numerous and typically include reduced global costs such as mould fabrication, labour, maintenance and speed of construction. For more than a decade, UHPC has been used in innovative ways to provide new solutions for structural and or architectural markets. Applications include bridge beams and decks, solid and perforated wall panels/facades, urban furniture, louvers, stairs, large-format floor tiles, pipes and marine structures.
In the recent months PCT has invested heavily in adding machinery to its production cycle. Machines include CNC wire cutting machines, CNC polishing/Honing machines, CNC milling machines, CNC Sawing machines.
PCT’s new marble cutting facility houses some of the top range 3D Milling machines in the business. Having experienced machinists and craftsman on the team has also been crucial to the project.
Working with natural components like wood, stone and marble are challenging because of the lack of uniformity in its natural stage. This means that at times the material has to be prepped before it goes into the process of machining.
PCT’s combined expertise of craftsmen who have experience of the material and machinists with the knowledge of the techniques required have helped overcome these challenges. This combination has helped to integrate expertise on both sides to increase the capacity by borrowing from mainstream production machining techniques.
