Choosing the right brick for your building project is a crucial decision that can significantly impact the structure, durability, energy efficiency, and overall appearance of your work. With so many types available, from common and facing bricks to engineering or handmade options, the selection process can be confusing without clear guidance. Strength, water resistance, frost durability, and even local planning requirements all need to be considered, alongside visual impact.
In this guide, we’ll walk you through the key factors to consider: the difference between structural and decorative bricks, matching materials to environmental conditions, sustainability concerns, and practical tips for choosing confidently.
Why Brick Type Matters
Bricks might all look similar at first glance, but their composition, strength, and purpose can vary significantly. Choosing the wrong type of brick for a job can lead to problems down the line, from structural issues to premature weathering or damp ingress.
At its core, brick choice is about function as much as form. Some bricks are designed to bear loads and withstand high levels of stress, while others are purely decorative and chosen for their finish. Selecting the right type ensures your project meets both performance and aesthetic expectations.
Different kinds of bricks also have varying levels of resistance to moisture, frost, and chemicals. For instance, a brick that works well for an internal partition may fail quickly if used for an exposed garden wall. Similarly, using a decorative brick in a load-bearing situation may result in cracking or long-term structural weaknesses.
Beyond structural suitability, the type of brick you choose can also impact:
- Thermal performance
- Fire resistance
- Build speed
- Planning permission compliance, particularly in conservation areas
Understanding the role each type of brick plays in a project is the first step toward making an informed, confident choice, whether you’re laying a few metres of garden wall or planning a full extension.
Structural vs Decorative Bricks
Not all bricks are created equal. Some are engineered to support the weight of a structure, while others are designed to deliver an attractive finish. Knowing which to use, and where, is essential for both safety and longevity.
Load-Bearing Bricks
These bricks are made to carry weight. They are denser, stronger, and more durable than standard facing bricks and are used where structural integrity is essential. Common types include:
- Engineering bricks: Available in Class A and Class B ratings, these are designed for high strength, low water absorption, and frost resistance. They’re ideal for use below the damp-proof course (DPC), in retaining walls, manholes, and areas exposed to chemical or water ingress.
- Concrete blocks: Often used in structural walls, particularly below ground or where a greater load is required. They offer excellent compressive strength and speed up build time.
These are the visible, outer layers of a wall. While some facing bricks offer decent strength, their main function is to provide an attractive finish and protection from the elements. Options range from smooth modern bricks to handmade or reclaimed styles with more variation in texture and colour.
These are ideal for:
- House exteriors
- Boundary and garden walls
- Feature walls or fireplaces
- Projects in conservation areas requiring visual consistency
Key Point:
Some bricks can perform both roles – for instance, certain facing bricks may be strong enough for limited structural use. However, it’s best to check the product specifications or speak with an expert before assuming suitability.
Choosing the Right Brick
When selecting bricks, it’s important to think beyond aesthetics. Where and how the brick will be used, and the conditions it will face, should guide your decision.
Exposure to Weather
If your project involves external walls, garden features, or retaining walls, opt for bricks with good frost resistance and low water absorption, such as engineering bricks or high-quality facing bricks. For below-DPC areas, use Class A engineering bricks.
Location and Function
- External walls: Use durable facing bricks that match your design and local planning requirements.
- Interior work: Common bricks or blocks may suffice for unseen areas.
- Retaining walls: Prioritise strength and moisture resistance.
- Decorative features: Handmade or reclaimed bricks offer texture and character, ideal for heritage work.
Visual Matching
When extending or renovating, matching colour, texture, and size (e.g. imperial vs metric) is key to a seamless finish. Ordering samples is recommended.
Sustainability Considerations
Choosing bricks with sustainability in mind can have long-term benefits for both your project and the environment. At MP Moran, we support responsible building practices by offering options that reduce waste, conserve resources, and lower carbon impact.
Reclaimed Bricks
One of the most sustainable choices is to use reclaimed bricks, which have been carefully salvaged from previous construction. These bricks offer several advantages:
- Reduced environmental impact - no new manufacturing is required
- Distinctive character and patina, ideal for matching period properties
- Suitable for renovations, extensions, and conservation areas
MP Moran offers a range of reclaimed bricks in varying colours and finishes, making it easier to match existing masonry or add heritage appeal to a new build.
