Why Raked and Struck Mortar Joints Can Cause Problems

Why Raked and Struck Mortar Joints Might Make You Raise an Eyebrow

When it comes to masonry work, it’s easy to get caught up in the aesthetics. After all, who wouldn’t want their building to look sharp? But let's pause for a second here. Are we sometimes focusing too much on the style at the expense of functionality? Take raked and struck mortar joints, for instance. While they might seem trendy or sleek, they might be leading you down the wrong path when it comes to moisture management. Yes, these joints can create some significant challenges.

What’s the Deal with Mortar Joints?

First things first—what exactly are mortar joints? In simple terms, these are the spaces between bricks or stones that are filled with mortar to hold everything in place. Think of them as the glue that binds your building together. When designed properly, they can enhance the structural integrity and aesthetic appeal of a masonry wall. But like many things in life, it’s crucial to consider the “how” as much as the “what.”

Now, let's shine a light on raked and struck mortar joints specifically. Both designs offer a unique look—the raked joints create a recessed effect, while the struck joints have a slight slope—but there’s a catch.

The Subtle Trap of Water Accumulation

Have you ever noticed how, after a good rain, water tends to linger in certain places? Well, that’s exactly what’s going on with raked and struck mortar joints. You see, both designs create a ledge where water can easily collect instead of flowing off or draining away. This is a common issue that can lead to some serious long-term headaches.

When water sits stagnant on a joint, it doesn’t just disappear. Oh no. Instead, it sneaks into the wall over time, causing all sorts of problems you might not notice immediately.

A Cascade of Concerns

So, what happens when moisture makes itself at home? It can lead to mold growth, which is not just a nuisance but can be harmful to health. You wouldn’t want your home harboring some uninvited guests, would you? Over time, too much moisture can also cause materials to deteriorate. Imagine putting down a new wooden deck only to find out it’s buckling in a year because it couldn’t handle the moisture.

Not to mention that incessant crumbling you might see on the exterior of your wall. Yes, folks, excess moisture can lead to cracks in the masonry itself. In the long run, this can compromise the structural integrity of the wall, and nobody wants that kind of trouble knocking at their door.

Choosing Wisely: Alternatives to Raked and Struck

Now that you know about the perils of raked and struck mortar joints, you might be wondering: “What’s the alternative?” Great question! There are actually plenty of ways to design mortar joints that look good and keep water moving away from your building.

Consider flush joints—with these, the mortar is finished to sit at the same level as the brick face. This design helps water to easily flow off the walls instead of pooling. Or how about weathered joints? They’re slightly angled and help guide water away.

Each of these options can provide the curb appeal you’re looking for while keeping your building safe from moisture problems.

Wrapping it Up: The Bigger Picture

In the world of construction and masonry, the importance of effective water management cannot be overstated. We tend to focus a lot on what looks appealing, but remember, functionality is key. When you choose the right joint design, you’re not just building a wall; you’re building a fortress against moisture.

So next time you’re contemplating that raked or struck joint, pause and ask yourself—"Is this really the best choice for my building?" There’s beauty in practicality, after all, and it could save you from avoidable headaches down the line. Keeping your walls standing strong requires attention to detail, and those details should include how water interacts with your materials.

In the grand scheme of things, each choice in reputable construction—from the mortar joints right down to the last brick—can contribute to a building’s longevity. And who wouldn't want that kind of peace of mind? So, here's to making smarter choices and creating lasting structures!
