GRC (Glassfibre Reinforced Concrete) is a composite material made of a cement/aggregate slurry reinforced with alkali-resistant (AR) glass fibers. It is a versatile and durable material with various applications in architecture and construction.

GRC offers numerous benefits over traditional construction materials:

Lightweight: GRC is significantly lighter than precast concrete, reducing structural loads and transportation costs.
High Strength: Despite being lightweight, GRC has high tensile and flexural strength due to the AR glass fiber reinforcement.
Durability: GRC is resistant to weathering, fire, and impact, making it suitable for various environmental conditions.
Design Flexibility: GRC can be molded into complex shapes and forms, offering architects greater design freedom.
Cost-Effectiveness: GRC's lightweight nature reduces material and labor costs compared to traditional materials.

GRC is commonly used for:

Cladding panels: Non-structural exterior panels for aesthetic and weather protection.
Rainscreens: GRC panels can be used to create ventilated facades for improved thermal performance.
Architectural elements: Cornices, moldings, columns, and other decorative features.
Street furniture: Benches, planters, waste receptacles, and other urban amenities.
Drainage channels: Durable and lightweight channels for water management.

Liquidstone is committed to high-quality GRC products. Their quality control measures include:

Experienced Personnel: Qualified engineers, drafting personnel, production staff, and quality control managers oversee all stages of production.
Documented Procedures: Stringent procedures for material inspection, shop drawing approval, and production processes.
Testing and Inspection: Regular testing of materials and finished products to ensure compliance with specifications.
Comprehensive Quality Manual: Detailed guidelines for GRC production, ensuring consistent quality standards.

Key considerations for designing with GRC include:

Mix Design Compatibility: Ensure compatibility between the face mix and the GRC backing mix to minimize cracking and delamination.
Volume Change: Account for thermal and moisture-induced volume changes in GRC to prevent warping or cracking.
Anchor Design: Properly design and test anchors for handling, transportation, erection, and service loads.
Tolerance Requirements: Establish realistic and achievable tolerances for GRC elements in coordination with other trades.
Finish Selection: Consider the desired aesthetic and performance characteristics when selecting GRC finishes.

Yes, Liquidstone offers technical support to assist with GRC design and specification. This may include:

Shop Drawings: Preparation of detailed shop drawings for fabrication and installation.
Sample Panels: Provision of sample panels to demonstrate finishes and quality.
Technical Consultation: Expert advice on GRC design, material selection, and production processes.

Regular maintenance helps ensure the long-term performance of GRC elements:

Cleaning: Periodically clean GRC surfaces to remove dirt, stains, and efflorescence.
Sealer Reapplication: Reapply sealers as needed to maintain water repellency and protect against weathering.
Inspection: Inspect GRC elements for any signs of damage or deterioration.
