In our extensive experience inspecting new build properties across the UK, we frequently encounter mortar-related issues that could have been prevented with proper quality control.
One of the most frequent issues we discover is inconsistent mortar mix throughout the property. You might notice this as variations in colour across your walls, but it’s more than just an aesthetic concern. Inconsistent mixing often indicates varying strength and durability, which could lead to problems down the line.
Water-related issues are another significant concern. We regularly find instances of damp patches on internal walls, white salt deposits (known as efflorescence) on bricks, and mortar erosion. These problems often stem from mortar that isn’t properly resistant to water or doesn’t allow appropriate moisture movement through the walls – a particular concern in the British climate.
Poor workability during construction can lead to visible defects that you might spot in your new home. These include uneven joint sizes, mortar squeezed out beyond the joint lines, and gaps or voids in joints. While some might consider these merely cosmetic issues, they can actually indicate more serious underlying problems with the mortar’s composition or application.
We’ve also encountered cases of premature deterioration, where mortar starts to crumble or erode much earlier than it should. In a properly built new home, the mortar should last for decades without significant deterioration. Early signs of wear could suggest serious quality issues with the materials or mixing process.
The Importance of Proper Testing
These common issues highlight why professional mortar testing is so crucial during construction. Testing follows strict British Standards (BS EN 1015) and helps ensure the mortar will perform as intended throughout your home’s lifetime. Professional testing evaluates everything from the mortar’s consistency and strength to its water resistance and durability.
In the UK, proper mortar testing requires accredited laboratories and follows rigorous protocols. While this might seem like a technical detail far removed from your daily life, it’s actually crucial to your home’s long-term durability and value. Well-tested, quality mortar typically lasts the lifetime of the building, while poor quality mortar can lead to expensive repairs and ongoing maintenance issues.
Protecting Your Investment
If you’re concerned about the mortar work in your new build property, there are several signs you can look out for. Watch for any unusual cracking patterns in your walls, signs of damp, or noticeably inconsistent appearance across different sections of mortar work. While some variation is normal in construction, significant differences could suggest underlying problems that require attention.
It’s worth noting that mortar issues often become more apparent over time, particularly after the property has been exposed to different weather conditions. That’s why a thorough inspection is so important.
