UHQGRC
Application

Sealed joint cladding, open joint rainscreen cladding, 3D architectural dressings, coping elements, landscape garden features.

Description

High quality glass fibre reinforced concrete cladding elements.


Features and benefits:

  • High flexural strength and durability when compared to typical glass reinforced concrete (GRC) materials.
  • GRCA Equivalent Grade 21P.
  • Versatile: Available in a range of bespoke shapes and sizes.
  • Provides the appearance of natural stone (at a lower weight).
  • Fire-resistant.
  • Available in a range of facing coats to provide an appearance similar to architectural pre-cast concrete. Facings coats have a high compressive strength and low water absorption. All facing coats are developed in UKAS accredited testing facilities to ensure validated compatibility with GRC mixes.
  • Meets/exceeds the most onerous requirements of BS EN 1169 (General Rules for Factory Production Control of GRC), GRCA Specification for Manufacture, Curing and Testing of GRC and PCI MNL-130-09 (Manual for Quality Control for Plants and Production of GFRC Products).
  • Manufactured under a BSI accredited Quality Management System to ISO 9001: 2015.
  • Full UKAS accredited testing to ISO 17025: 2017.
