Product Description:

The GRC division was initially set up in Al Quoz Industrial Area in Dubai with the manufacturing facility covering an area of over 200,000 square feet. To meet the current and future requirement it has expanded into a state of the art manufacturing facility spanning over 400,000 square feet in Dubai Industrial City. Terrazzo can boast of having one of the biggest GRC plants in the Middle East currently.

 

Terrazzo GRC has manufactured and installed a large variety of GRC products. Some of them are mentioned as follows:

 

  • Cladding panels, Fascia Panels
  • Screens, Decorative panels, GRC screens
  • Cornices, coping, brackets
  • Window & Door surrounds
  • Domes
  • Column cladding, pedestals, capitols & base
  • Arches
  • Railing, Balustrades
  • Pergolas
  • Planters
  • Constellations
  • Ceiling Claddings
  • Benches
  • A/C Covers
  • Fountains
  • Signage Boards
  • GRC Gazebo
  • Inside Architectural Components, Domes, Column Cladding, etc.
  • Arch Panels, Cornices, Castellations, etc.,
  • Other custom made products

Terrazzo has emerged as one of the largest GRC manufacturing companies in the Middle East and other parts of the world over the last decade. Commitment to quality and innovative finishes has resulted in the company bagging majority of prestigious GRC cladding projects in the past decade in the region.

 

Terrazzo at present has an agreement with M/s. Owens Corning Vertrotex, UK for the technical know-how and materials technology to manufacture and install Glass Reinforced Concrete Products.

 

Terrazzo is a long term and active Full Member of Glass Reinforcement Concrete Association International (GRCA International), UK enjoying the first hand information on the latest technology & developments in GRC products.

 

GRC division is one of the oldest divisions of Terrazzo to have been ISO certified and currently holds ISO 9001-2008 certification for Design & Manufacturing of GRC for the construction industry by Intertek Certification, AB-Kista (Stockholm) Sweden under the accreditation of SWEDAC, Sweden.

 

Glass Fibre Reinforced Concrete, popularly known as GFRC or GRC is a mixture of cement, fine aggregate, water, chemical admixtures and alkali resistant (AR) glass fibres. The most commonly adopted manufacturing processes are Hand Spray and Premix.

Glass Fibre Reinforced Concrete (GFRC) is a material which today is making a significant contribution to the economies, technology and aesthetics of the construction industry worldwide. It can be used as a good thermal insulator as well as fire retarder.

MANUFACTURING METHOD:

Glass Reinforced Concrete (GRC) or Glass Fibre Reinforced Concrete (GFRC) is generally manufactured by either “Spray” process or “Premix” vibration casing process The method chosen is normally dictated by factors such as strength requirements, sizes of mould, architects specification, etc. As a general rule, larger items, such as building cladding panels etc. are normally sprayed whereas small items are manufactured from Premix GRC Process.

 

In Spray GRC process, products with thinner sections are preferred whereas in Premix GRC process, products with thicker & see through (screens) sections are preferred.

 

TYPES OF GRC FINISHES

 

  • GRC White / GRC Cement Smooth Finish

    The white smooth finish GRC is a combination of a specially developed mortar of AR glass fibre, white cement, sand, water and admixtures.

    This has high cement and low aggregate content, which makes it a lower permeability product resulting in higher resistance to moisture penetration.

  • GRC Pigmented Finish

    The Pigmented GRC is a combination of a specially developed mortar of AR glass fibre, white cement, sand, water, and natural / synthetic pigments along with admixtures.

    The colour matrix and GRC mix design and blended and graded together to produce pigmented GRC Panels in multiple colours and shades.

  • GRC Acid-etched Finish (Fine Stone Aggregate)

    The Acid-etched / Fine Stone Aggregate finish GRC is a specially developed mortar of AR glass fibre, white cement, sand, water, and natural / synthetic pigme nts and fine aggregate of Marble / Granite treated with acid bath and then is cleaned with high pressure water to give uniformity in colour and fine stone aggregate texture.

  • GRC Exposed Aggregate Finish

    The Exposed Aggregate finish GRC is a specially developed mortar of AR glass fibre, white cement, sand, water and natural / synthetic pigments and coarse aggregate of Marble / Granite. GRC receives retarder treatment from the mould and then is cleaned with high pressure water to give uniformity in colour and coarse aggregate texture.

GRC is one of the most popular materials used for creating prefabricated architectural cladding. GRC’s ability to be moulded into lightweight panels with variable thickness with a variety of shapes, forms and surface finishes has been appreciated by a growing audience of architects and engineers worldwide.

  • GRC is easily moulded to reproduce shapes, details and textures.
  • GRC is a high strength material that allows design of thin, lightweight cladding elements.
  • GRC can be coloured with pigments, paints and natural stone facings.
  • GRC cladding can replace non-structural precast concrete where weight and/or shape may be problematic.
  • GRC can be cast into fine details.
  • GRC offers designers unrivalled flexibility.
  • GRC mouldings and features are easy to handle and erect.
  • GRC does not suffer from corrosion.
  • GRC is an environment friendly Green Product.
  • GRC products reduce loadings on buildings leading to significant savings in superstructure and foundations.
  • GRC is excellent for reproduction and renovation.

 

GRC products are formed by a variety of manufacturing techniques. One of the most versatile techniques is to cast the composite in moulds manufactured from rubber, timber or Glass Fibre Reinforced Plastic (GFRP/GRP). 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 details to be created.

GRC is used to produce beautiful architectural mouldings and features. Whilst often cast with thicknesses in excess of 25mm these products remain easy to handle and erect and permit the architect or engineer an unrivalled freedom for creative design. GRC does not suffer from corrosion of the reinforcement. Unlike traditional concrete, GRC does not require a minimum of concrete cover to the reinforcement.

 

GRC cladding panels are generally manufactured by the “Hand Spray’ technique. As the name implies, the material is sprayed into a mould using special machinery. The method can produce high-performance materials from which panels with extremely thin, lightweight sections are achievable.

 

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 aggregates, coloured or simply left with a natural white or grey, smooth or textured finish.
