What it’s Made From
Clay
The primary material, typically sourced locally, is used for its plasticity and strength after firing.
Water
Essential for shaping and moulding the clay into bricks.
Sand
Used to prevent the bricks from sticking to moulds and for creating textured finishes.
Additives
These can include materials like manganese, barium, and other colorants to enhance color and durability.
Variations
Red Cavity Liner Brick
Description: A traditional red-colored brick designed to line cavities and provide structural support.
Applications: Used in constructing internal walls, providing a classic aesthetic while ensuring stability and strength.
Buff Cavity Liner Brick
Description: A light yellow to sandy-colored brick that offers a warm, clean appearance for cavity walls.
Applications: Ideal for modern buildings and extensions, enhancing both structural integrity and visual appeal.
Blue Engineering Cavity Liner Brick
Description: Known for its high strength and low water absorption, typically in a dark blue hue.
Applications: Suitable for areas requiring robust support, such as foundations and below ground level constructions, while also providing an aesthetic feature.
Installation
Tools Required:
Trowel | Spirit level | Brick | hammer | Tape measure | Brick jointer
Materials Required:
Cavity liner bricks | Mortar mix | Water | Damp-proof course (DPC) material
Step-by-Step Guide:
Preparation: Clear the area, lay a damp-proof course (DPC).
Mix Mortar: Follow manufacturer’s instructions.
Lay Bricks: Start with a mortar bed, place bricks, check alignment.
Build Up: Lay bricks with mortar in between, ensure each layer is level.
Insulation: Insert insulation in the cavity if needed.
Complete: Fill gaps with mortar, smooth joints, clean excess mortar.
Technical Specification
Load-Bearing Capacity: Suitable for use in load-bearing walls, providing structural support.
Thermal Properties: Enhances thermal insulation of cavity walls, contributing to energy efficiency.
Acoustic Properties: Offers good sound insulation properties when used in cavity wall construction.
Compliance and Standards: Complies with relevant British Standards (BS EN 771-1) for clay masonry units.
Certification
ISO 9001: Quality management certification.
BS EN 771-1: British Standard for clay masonry units.
CE Marking: Indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA).
Purchasing Quantities
Single Units
Ideal for small projects, repairs, or when only a few bricks are required.
Bundles
Available in smaller quantities than pallets, often sold in bundles of 10, 20, or 50 bricks, suitable for minor projects or additions.
Pallets
Typically offered in bulk, with each pallet containing around 400 to 500 bricks. Suitable for medium to large construction projects.
Environmental Impact
Sustainability: Clay cavity liner bricks are made from natural materials and can be recycled.
Carbon Footprint: Moderate carbon footprint due to firing process but long-lasting durability offsets environmental impact.
Eco-Friendly Alternatives: Recycled plastic cavity liners or sustainably sourced timber products can be considered as environmentally friendly alternatives.
