3. ABOUT EDENHALL BRICKS
3.1 The Manufacturing Process
The process for manufacturing Edenhall bricks is efficient and flexible allowing adjustments to production plans to be
made quickly and easily in response to market demands.
Production involves the compaction of a semi-dry mix of graded aggregates, cementitious material, water, pigments
and additives. During the mixing process various combinations of pigments and additives can be introduced depending
on the particular brick that is required. The whole process is computer controlled to ensure that replication of the recipe
can be maintained for future requirements. Secondary treatments for texture and colour can be applied to the brick as
and when required.
The resultant “green” or uncured bricks are transferred to chambers where the exothermic reaction of the cement
increases the temperature and humidity so that the product cures naturally. Minimal additional heat is required, thus
CO 2 emissions are significantly reduced. Once the bricks are cured in the chambers they are packaged and
shrink-wrapped and left to further cure in the stockyard until they are required on site.
3.2 The Benefits of Edenhall Bricks
• The aggregate raw materials are generally sourced locally and are often classed as a by-product of primary, clean
graded aggregates.
• Cements are generally sourced from UK production facilities and are supplemented by environmentally beneficial
replacements with pozzolanic properties.
• The amount of water used in production is extremely low and can come from recycled sources.
• Facing bricks can be made to prescribed mixes which can be replicated at different Edenhall factories, thus
reducing distribution costs.
• Edenhall bricks will continue to age harden throughout their life cycle. They have virtually no soluble salts and can
be crushed and recycled at the end of their life.
• Edenhall bricks have low cement content, aided by the pozzolanic characteristics of the fine aggregate, thus
minimising the carbon footprint whilst maintaining their strength and durability properties.
• The composition of the bricks means they are fire resistant, have an A+ rating, and their density can offer
enhanced levels of sound reduction in flanking walls or lightweight structures.
• Edenhall’s factories are strategically placed throughout the country thus enabling us to minimise our transport
mileage which in turn reduces our carbon footprint. We do not need to import bricks to support demand.
• The embodied and emitted carbon content is low and they are a net absorber of CO 2. Edenhall bricks typically will
