In this blog, we’ll dive deep into Corefix, exploring why it’s the best choice, how it compares to other fixings, and how you can install it in just minutes.
Understanding Dot and Dab Cavity Walls – Why Standard Fixings Fail
Modern homes are often built using dot and dab plasterboard walls, a method where plasterboard is bonded to solid brick or block walls using adhesive “dabs”.
This leaves a gap between the plasterboard and the solid wall, which can cause serious issues when attaching heavy loads.
Common Problems With Standard Fixings on Dot and Dab Walls
❌ Plasterboard Collapse: Regular wall plugs crush the plasterboard, leading to weak and unsafe fixings.
❌ Weak Load Bearing: Standard fixings are not designed for heavy loads in cavity walls, causing them to fail under pressure.
❌ Wobbling Fixtures: Over time, loosening occurs, making your TV mount, boiler, or shelving unstable.
❌ Risk of Damage: Incorrect fixings can damage the plasterboard, creating costly repairs.
The Corefix Solution – Bridging the Gap for Maximum Strength
Corefix Dot and Dab Cavity Wall Fixings are designed to solve these problems by incorporating a steel core that transfers the weight directly to the solid wall behind.
This means:
✅ No more crushed plasterboard
✅ No movement or wobbling over time
✅ Supports heavy loads safely and securely
