Glassfiber Reinforced Concrete

Glassfiber Reinforced Concrete (GRC) was introduced by GEL in 1979 with product knowhow from Pilkinton Brothers Ltd. of England. Since then GRC has been adorned to many of Bangkok's most recognized buildings such as Wall Street Tower, Peninsular Plaza, Amarin Plaza and the New Grand Hyatt Erawan Hotel. GRC is a unique mixture of cement, sand and reinforced with a special glassfiber to replace reinforced steel. Consequently, the long lasting workpiece will be thinned but strengthened, easily formed into variety shapes which is suitable for various decorations for both interior and exterior.

Glassfiber Reinforced Concrete components are Portland cement, sand and 5%glassfiber by weight mixed with water in the right proportion. Then, wait for GRC panel to set as general concrete, and will get the panel that is strong, durable and required shape.

Suitable work for GRC

1. Façade

  • Roofing

Roof design is an important part of showing buildings identity. Sometimes, it is difficult to design and produce the roof to get as needed with general construction materials because the type and weight of materials are the main concern of overall building. However, Glassfiber Reinforced Concrete can be formed in various shape and become lighter than general reinforced concrete structures. Thus, this can reduce the load of overall structures.

  • Cladding

Cladding is similar to the face of the building therefore, the materials are depended on the designers’ intention. As for Glassfiber Reinforced Concrete, it is given strong and durable feeling as concrete. Furthermore, it can be designed with various shapes such as curve and angle. Additionally, Glassfiber Reinforced Concrete can be produced thinner than steel reinforcement concrete which makes it to be a light panel and also save structure cost of cladding supporting.

2. Interior decoration

  • Wall, Window frame and Decorative column

Glassfiber Reinforced Concrete is suitable for both interior and exterior decoration, especially wall, window frame and decorative column according to the taste of the owner or designer. It can be different from other decorative materials. It also can be formed in various shapes and textures such as smooth, wood or graphic textures including unlimited color shades. It’s also produced by making attached surface with other materials such as mosaic tile, mirror and brass plate etc.

3. Landscape

Due to Glassfiber Reinforced Concrete is made from cement components, it can be designed in various shapes with a good natural shape and can be replaced natural materials with long lifetime, bears with climate resistance and maintains material strength. Thus, it is suitable for making cave, waterfall, outdoor sculptures etc.

4. Special Projects

  • Permanently Installed Formwork

In some of construction projects, there is the design of the reinforced concrete structure as a special shape such as steel reinforcement concrete with dome roof shape. Formwork preparation cannot be made from general formwork since it has to create formwork with 3D curve. Therefore, Glassfiber Reinforced Concrete is the right choice of this kind of work. It is produced from cement which is durable, strong and has long lifetime similar to general reinforced concrete. Additionally, Glassfiber Reinforced Concrete surface can be used as the real surface of architectural work which is good-looking and reduce working time.

  • Renovation with architectural

Architectural conservation renovation can be done by copying the prototype from the valid original parts to form the mould and producing the workpiece with Glassfiber Reinforced Concrete. The workpiece is similar to the original workpiece and can be attached other decorating materials on surface. Therefore, this will be more convenient and faster than onsite work by high skill craftsman.

  • Noise Barrier

Noise Barrier Glassfiber Reinforced Concrete is an excellent sound proof system that has ability to reduce the frequency of traffic noise. Noise barrier is used for reducing noise from the sound source to the receiving point which can be divided into 3 types:

  1. Reflection Panels
  2. Dispersion Panels
  3. Absorption Panels
GRC is one of the most versatile building materials available to architects and engineers.

Glassfiber Reinforced Concrete

GRC presents architects and engineers with a material from which the most ambitious designs or to replicate traditional historic features. It can be painted, faced with fine aggregates, coloured or simply left with a natural white or gray, smooth or textured finish.

  • GRC products are lightweight, easy to handle and fast to erect
  • GRC excellent for reproduction and renovation
  • GRC products reduce loadings on buildings leading to significant savings in superstructure and foundations.
  • GRC environmentally friendly
  • GRC provides the designer with a complete technology that few other materials can match for versatility
