GFRC is a type of concrete that uses glass fibers for reinforcement instead of steel. It is typically cast in a thin section. Since the fibers cannot rust like steel, there is no need for a protective concrete cover thickness to prevent rusting. With the thin, hollow construction of GFRC products, they can weigh a fraction of the weight of traditional precast concrete.
GFRC can be used wherever a light, strong, weather resistant, attractive and fire retardant material is required. GFRC can be used in manufacturing architectural products such as wall panels, window surrounds, column covers, soffits, cornices, brackets, quoins, railings, pilasters, copings, domes, site furnishings, planters, bollards, urns and tables.
Glass fiber reinforced concrete has been tested both by accelerated aging tests in the laboratory and in real life installations. GFRC can be expected to last as long as pre-cast concrete. In many environments, as when exposed to salt spray or high moisture, the GFRC can be expected to perform better, as there is no steel reinforcement to corrode. Since the surface of GFRC is a Portland concrete, it weathers much as a quality architectural pre-cast concrete would.
• Made of minerals and will not burn. In addition, the nature of concrete acts likes a thermal regulator when exposed to flame. GFRC not only will not burn, but it also protects the materials behind it from the heat of the flame.
• Relatively light in weight compared to traditional stone or terra cotta ornaments. Its installation is quick and relatively easy.
• Can be casted to virtually any shape. We supply wall panels, columns, bas relief, domes, column capitals, fireplace surrounds, moldings, medallions and all types of custom GFRC shapes.
• Available either with a cast in integral color and texture: limestone, precast, acid wash, etc. or as paint grade that is easily finished with virtually any paint
GFRP can be used for both interior and exterior fixtures in a variety of shapes, styles, and textures; in new buildings or restorative projects. (Domes, Fountains, Columns, Balustrade, Planters, Panels, Sculpture, Entryways, Moldings, Facades, Cornice, Porticos, Cupolas, Signs and Roofs
Glass Fiber Reinforced Plastic (GFRP or GRP) Fiberglass is a type of fiber-reinforced plastic where the reinforcement fiber is specifically glass fiber. The glass fiber may be randomly arranged, flattened into a sheet (called a chopped strand mat), or woven into a fabric. The plastic matrix may be a thermosetting plastic – most often epoxy, polyester resin – or vinylester, or a thermoplastic.
A mold is then made of fiberglass, steel, wood or rubber depending on the detail. Into this mold a carefully designed mix of polyester or epoxy resin is sprayed, along with alkali resistant glass fibers. Virtually any shape or form can be molded.

• High Strength - GFRP has a very high strength to weight ratio
Lightweight - Low weights means faster installation, less structural framing, and lower shipping costs
Able to Mold Complex Shapres - Virtually any shape or form can be molded
• Resistance - Resists salt water, chemicals, and the environment unaffected by acid rain, salts, and most chemicals
• Seamless Construction - Domes and cupolas are resined together to form a one-piece, watertight structure
• Low Maintenance - Research shows no loss of laminate properties after 30 years
A new product now known as Glass Fiber Reinforced Gypsum (GFRG), also referred to as Fiberglass Reinforced Gypsum (FRG) and Glass Reinforced Gypsum (GRG). This included gypsum plaster reinforced with glass fibers to produce a thin, lightweight, yet strong material.
GFRG is primarily composed of two raw materials: high density alpha-based gypsum and glass fiber reinforcement. The gypsum plaster should be neutral or of low alkalinity to ensure its compatibility with "E" glass fibers. Additives commonly used within the plaster industry are acceptable provided they are used in accordance with the gypsum manufacturer's recommendations.
GFRG is used where it is not subject to dampness. (Do not use where it is openly exposed to rain or for fountains, pools or wet locations. For these applications see GFRP). GFRG can be used wherever a light, strong and fire retardant material is required (hotels, theaters, residential, etc. Moldings, Ceilings, Columns• Light coves, Domes, Capitals, Fireplace Surrounds, Custom shapes
• Flame Resistant - GFRG is a mineral and will not burn. In addition, the nature of gypsum acts like a thermal regulator when exposed to flame. GFRG not only will not burn, but it also protects the materials behind it from the heat of the flame for up to two hours.
• Easy Installation - GFRG is relatively light in weight compared to traditional stone or plaster ornaments. Its installation is quick and relatively easy.
• Selection - GFRG can be cast to virtually any shape.
• Finish - GFRG is available in a white color and is easily finished with virtually any paint.
DCS are the pioneers’ of UHPC Manufacturing in Qatar, DCS with the cooperation of Dyckerhoff (Germany) and guidelines of Durcrete Consulatnt (Germany) successfully developed the UHPC Mix Design to meet the required Specifications (180 Mpa Compressive Strength & 25 Mpa Flexural Strength).
Dyckerhoff has signed an exclusive agreement with Doha Cladding Solutions (DCS) for the export of special Nanodur to Qatar. DCS takes care of the import procedure, supervision and can easily carry out mix demonstrations to ensure an uncomplicated access to UHPC. The agreement grants DCS exclusivity for the purchase of Nanodur Compound within Qatar.
UHPC, or Ultra High Performance Concrete, is a class of concrete defined by its exceptionally high streghth and durability. It was developed in Europe in the 1980s for specialized applications that demand superior strength and corrosion resistants - marine anchors, piers and seismic structures.
More recently, the use of UHPC has expanded to applications requiring its high strength in narrow profiles, such as bridge spans and building facades in which the material's strength, wear resistance, lighter weight and lower life cycle costs have been the driving determinates.
UHPC is structurally more comparable to steel than traditional concrete. As a result, far less material (-70%) is needed to achieve the same structural requirements. This leads to much lower weight, less substructure when used as a facade as well as lower shipping and installation costs. In addition, because UHPC does not contactin the capillaty pores of traditional precast or glass-reinforced concrete, it does not absorb water and degrade in severe marine conditions.
