#### How do brick walls not fall over?

How gravity works against buildings – All kids like building things! Whether we’re stacking LEGO® blocks or playing cards in the living room, sticks in the forest, or sandcastles on the beach, we’re all architects and builders at heart. Think back to the last time you made something in this way.

1. What was the biggest problem you faced? One of the things that would have worried you was the possibility of your building toppling over once it reached a certain height.
2. That’s also true in the real world, where the number one problem any builder faces is keeping their structure upright.
3. The trouble is all to do with gravity : the magnetic -like force of attraction between any two objects in our universe.

On Earth, we see gravity as a tendency for things to fall toward the floor, but gravity always work two ways. If you drop a pen, it does indeed fall toward the floor—but the floor also jumps up by a microscopic amount to meet it on the way! The force pulling your pen down toward Earth is exactly the same size as the force that pulls Earth up toward your pen.

Now gravity usually pulls things straight downward, but it can act in other ways too. Suppose you built a really tall brick wall. We can think of gravity acting on it in two different ways. We can see it as a collection of separate bricks, with gravity pulling on each one separately. Or we can think of it as a solid wall with gravity pulling on the whole thing, just as though all its mass were packed into a single point in its center.

The place where an object’s mass seems to be concentrated is called its center of gravity, For a simple brick wall, the center of gravity is slap bang in the middle of the central brick. So what makes a wall fall over? If the center of gravity is over to one side (if we’ve not built the wall straight or if we’ve built it on sloping ground), the force of gravity acting down will produce a turning effect called a moment, Artwork: Why walls stay up and why they collapse. Left: If a wall is built upright or on flat ground, the center of gravity (blue dot) is directly above the center point of the wall’s foundations (yellow dot), so the wall is stable. Right: But if a wall is built on sloping ground, the center of gravity is no longer above the center of the base.

• Now gravity (red arrow) creates a moment (green arrow) that tips the wall over.
• The higher the wall, the greater the mass above the center of gravity, the greater the turning force and the more chance the wall will collapse.
• Now this doesn’t just apply to single walls: it applies to entire buildings.
• If a skyscraper is 200 m (650 ft) tall and a gale blows it hard at the top, there’s a huge turning force trying to tip the whole building over to the side.

That’s why tall buildings need deep foundations (where a significant part of the building is constructed underground to support the part that’s above ground). If something tries to push the top the building to one side, the foundations effectively resist and push it back in the opposite direction! In other words, they help to counter the moment that would make a building topple to one side. Photo: Question: How do you build deep foundations for a tall building without digging away tons of earth? Answer: Use a foundation drill like this. These amazing drills can sink foundations over 30m (100ft) into the ground. Some can drill holes about 2.5m (8.2ft) in diameter!

#### Can I build a wall between me and my Neighbour?

Party Walls or Structures A party structure is the term used to describe the wall, hedge, fencing, or building which is on, or close to, the boundary between two properties. It is essentially the structure which creates the physical division between two properties.

• A party wall/structure may be either on your neighbour’s property or on the boundary which divides the two properties.
• It is generally the case that the adjoining property owners jointly own the party structure and neither of them can make a unilateral decision to significantly alter or remove the party structure.
• Party structures have been problematic in the past, particularly so when it came to the maintenance and the carrying out of repairs to them so the Land and Conveyancing Law Reform Act 2009 addressed and sought to clarify the law in relation to party structures.
• The law entitles a person to carry out work to the party structures including for example alterations, repairs and maintenance, decoration, replacement and strengthening.

## Is a brick wall cheaper than concrete?

Poured Concrete Wall Vs Brick Wall Cost. A poured concrete wall is about 40% – 50% cheaper to build than a structural brick wall.

### How much does it cost to build a brick wall?

Brick Wall – Brick walls cost \$5 to \$45 per square foot depending on the type you choose:

Brick costs \$27 to \$45 per square foot, Traditional brick fences cost around \$35 per square foot. Veneer averages \$10 to \$30 per square foot, This one brick thick (4 inches) wall acts as a veneer against a steel or wood frame. Also known as a “Wythe.” Thin brick veneer costs \$5 to \$15 per square foot, These are about one inch thick and get stuck to a wall using a thin-set or similar cementing process. They add far less overall weight to the wall than a Wythe. Hollow costs \$20 to \$30 per square foot,

### Can I lay bricks without cement?

ONE of the simplest and most attractive ways to install a paved walk or patio is to use bricks laid on a bed of sand without mortar or cement.

## Why is there a gap between brick and wall?

Brick Wall Mystery, Solved The author’s son investigates a weep hole on a brick home. Photo by Hannah McKenzie. Q: There are gaps between some bricks around the base of my home. They seem to be intentional since they are all at the same height from the ground and the same distance from one another.

What are they? Should I be caulking them shut? A:Please put down the caulk and step away! Those gaps are called “weep holes” — a building code requirement that drains water out of brick exterior walls. Typically, behind the brick is a 1.5-inch cavity or air space and then the wood structure. The outer surface of the wood wall is usually wrapped with a material like Tyvek ® or foam insulation that keeps water droplets draining down and away from the wood and over metal flashing (imagine a continuous miniature children’s sliding board) that directs water to the weep holes.

Despite different material and construction options, the gist is that brick walls built with cavities are designed to get wet and make water flow down and out through weep holes or evaporate. Weep holes are spaced every two to four bricks in a horizontal run and are located above windows, doors and the ground.

Most often, they are open vertical gaps. Alternatively, there can be cotton rope, plastic tubes, louvers or mesh installed to prevent pests while still letting water escape. It is easy for mortar — the cement‑like mixture between the bricks — to fall into the wall cavity during construction and prevent weep holes from working, which is one of many reasons skilled masons are essential for home construction.

Those gaps are called “weep holes” — a building code requirement that drains water out of brick exterior walls. Some homes with brick cavity walls do not have weeps. Though not ideal, this situation is hard to remedy, and adding weeps is not suggested since they must be tied to flashing.

• Eeping the grout patched as it cracks over time is key to limiting the amount of moisture inside the cavity.
• For all houses, be on the lookout for signs of a moisture problem, such as mold, mildew or bricks with efflorescence (crystalline deposits) or spalling (flaking).
• Efflorescence is when water moves through brick and evaporates when it reaches the sunshine.

Salt dust left behind on the surface is a clue that weeps are not working or that an event has caused a lot of water to build up in the wall. Spalling is when moisture has accumulated to a point that the bricks crumble. Freeze/thaw cycles can also contribute.

Blocked or missing weep holes Irrigation Excess humidity from a malfunctioning dryer vent or kitchen/bathroom exhaust fan Plumbing leaks from pipes, appliances or fixtures Air conditioning condensation drainage Damaged roofs, bricks, grout, windows or doors funneling water into the wall

There are so many tiny details that keep our homes comfortable, healthy and dry. Being aware of how our homes work and noticing problems can help us find solutions before the damage gets out of hand. : Brick Wall Mystery, Solved
