Solid wall lintels are vital components in traditional masonry construction. They span openings in solid walls and support the weight of the brick or stonework above doors and windows.

These lintels are designed to distribute loads evenly across the span, preventing sagging and cracking while ensuring long-term structural stability.

What Are the Benefits of Solid Wall Lintels vs Other Types of Lintel?

Solid wall lintels offer several key advantages over other lintel types:

• Enhanced load-bearing capacity: Compared to timber frame lintels, solid wall lintels are more effective at supporting heavier loads and wider spans in masonry construction.
• Better thermal performance: Their construction reduces thermal bridging, helping to maintain energy efficiency in buildings with solid walls.
• Seamless integration: Solid wall lintels blend visually with existing masonry, ensuring a cohesive and traditional aesthetic.
• Durability: Unlike concrete lintels, they are less prone to corrosion and weathering, making them ideal for exposed locations.
• Versatility: These lintels can be customised for various wall thicknesses and architectural styles.

How Do I Determine the Appropriate Bearing Length for Solid Wall Lintels?

Correct bearing length is crucial for structural integrity. Consider these factors:

• Wall thickness: Thicker walls typically require longer bearings.
• Opening width: Wider spans demand more bearing surface.
• Load above: Heavier loads mean longer bearing lengths are needed to evenly distribute weight.

As a general guideline, provide a minimum bearing of 150mm on each end. Increase the length for heavier loads or wider spans.

What Are the Best Methods for Integrating Damp Proof Courses With Solid Wall Lintels?

Proper damp proofing is essential when installing solid wall lintels. Follow these steps:

• Install a damp proof course (DPC) beneath the lintel, extending beyond the width of the opening.
• Lap the lintel DPC with the wall DPC for a continuous moisture barrier.
• For cavity walls, use preformed cavity trays above the lintel to direct moisture away from internal structures.

4 Common Mistakes to Avoid When Installing Solid Wall Lintels

• Weak support during installation: Use props or timber supports until mortar cures—typically for at least 7 days.
• Incorrect sizing: Always match the lintel to the load and wall thickness based on structural calculations.
• Poor load distribution: Create a level bearing surface with a strong mortar bed for even support.
• Bad mortar joints: Ensure full mortar coverage and fill all vertical joints to maximise strength.

When Would I Use a Solid Wall Lintel Over a Steel Lintel?

Solid wall lintels are the preferred choice in several situations:

• Heritage and conservation projects where maintaining the building's original appearance is key.
• Environments requiring better thermal performance than steel can offer.
• Coastal or high-corrosion areas—solid wall lintels are more resistant to salt air and weathering than steel lintels.
• Wide masonry openings requiring greater structural support and integration with brickwork.
