Architectural GRC

BCM GRC Ltd have been making Glass Reinforced Concrete for over 25 years. As a member of the GRCA Approved Manufacturers Scheme, BCM GRC offer quality assured products made to the highest standard.

GRC offers several advantages over cast concrete:

  • GRC products are lightweight, easy to handle and fast to erect
  • GRC products reduce loadings on buildings leading to significant savings in superstructure and foundations
  • GRC is excellent for reproduction and renovation
  • GRC is environmentally friendly

GRC provides the designer with a complete technology that few other materials can match for versatility.

Architectural Cladding

GRC presents architects and engineers with a material from which the most ambitious designs can be created. It can be moulded to form modern futuristic designs or to replicate traditional historic features. GRC can be painted, faced with fine aggregate, coloured or simply left with a natural white or grey, smooth or textured finish. Here you can see its use, to produce the high quality finish required by Jaguar on one of their showrooms.

Features and Mouldings

GRC products are formed by a variety of manufacturing techniques. One of the most versatile is to cast the composite in moulds manufactured from rubber, timber or glassfibre reinforced Plastic (GRP/FRP). This is known as premix GRC. As the high-performance alkali resistant glass fibres are evenly distributed in the mix, the material is reinforced throughout, enabling products with the finest of detail to be created. GRC does not suffer from corrosion of the reinforcement and unlike traditional concrete, GRC does not require a minimum of concrete cover to the reinforcement

Architectural Renovation

GRC is an ideal material for use in renovation. Thin lightweight panels are easy to fix and minimise the weight imposed on the existing structure. In many cases the opportunity is taken not only to improve the aesthetics of the building but also to improve the thermal and acoustic properties.

Modular Building

GRC panels are light and easy to transport, small units such as modular bathrooms or telecommunication equipment housings can be shipped in one piece and rapidly lifted into position. The strength of GRC is sufficient so that, even thin skin construction, small modular buildings can be designed without heavy structural frames. GRC walls can incorporate thermal insulation, and the absence of steel reinforcement can be a benefit in electrical or telecommunications applications. Aesthetically, the full range of natural and applied finishes, and the freedom of design, which characterise GRC permit solutions to satisfy any architectural requirement.

 Specifying GRC

Glassfibre Reinforced Concrete is one of the most comprehensively studied construction materials on the market and its properties are well known.

The data from these studies and over 40 years of practical experience has led the Glassfibre Reinforced Concrete Association (GRCA) to establish an internationally recognised specification for the manufacturing, curing and testing of GRC products. The document of the same name should always be used when specifying GRC and is the basis for all good design. Click here to download a copy.
The design of GRC and it’s fixing is critical to the long term service life and should be backed up by the use of a specialist independent engineering practice.

This is something that BCM GRC Ltd would always recommend.

BCM GRC Ltd are happy to advise on the appropriate specification required or independent advise on the specifying of GRC can be found on the GRCA website  or by contacting the GRCA directly.
