When you’re planning to build a house, it’s easy to think of the many small things that will go wrong, and then add them up. But in fact, there are two big things that can go wrong with any house. One is the weather: not enough rain, or too much rain, or too much rain and wind. The other is the people who will live in the house.

When it comes down to it, these are very similar problems. If you have a home improvement project that needs to be done, we have a soil cement and more for all your home projects.

Speculation about climate change? We’ve got soil cement and more for all your home projects.

Weather? We’ve got soil cement and more for all your home projects.

I’m not implying that your problem is with the soil, or that soil cement will solve it. I’m saying that if you have a home improvement project that needs to be done, we may be able to help you.

If you want to understand soil cement, it helps to know about two other things. One is what you might call the “soil cement industry,” which consists of people whose job it is to make soil cement. This is not a small business; there are more than 500 companies in the United States alone. The second thing is something called “aggregate.” Aggregate is just dirt that has been crushed and graded into various sizes, usually for construction use.

Soil cement is made by mixing the soil with water and then adding a chemical called a polymer. The mixture sets up quickly into little hard bricks that can be used to repair cracks in sidewalks, driveways, and the like. It also can be used in swimming pools and other places where dirt might fall in during construction.

The largest manufacturers of soil cement are BASF SE (Germany), Cemex SAB de CV (Mexico), and Holcim Ltd (Switzerland). They make well over 80% of the total worldwide supply.

Home improvement projects are a lot like writing software. A good programmer can take some code you have and make it do what you want. A bad programmer can take some code you have and make it do something you don’t want. For example, bad programmers sometimes put in bugs that end up costing people money.

People who write computer programs also think about how their programs will be used. If a programmer has a program that lets other people edit a file, for example, the programmer might decide to put in extra protection so people won’t accidentally delete anything important.

People who write home improvements often don’t think about how their work is going to be used. They just build a deck or build the foundation for an addition to their house, and expect that other people will figure out how to use them later.

Home improvement is a good metaphor for the whole of entrepreneurship. The first step is to realize that you’re not building a house. You’re not worrying about that; you’re just getting rid of stuff.

Home improvement means taking something big, something that takes up a lot of space in your life, and getting rid of it. When you take out the couch, for example, you are making room for the things people actually want to do: lying on the floor or sitting in a chair, reading on an actual couch, or watching TV on an actual screen. That’s what people do with their lives: they create new spaces to contain where they want to be.

But as soon as you start thinking about your own life and what you need instead, you’ll realize there’s no way to get rid of everything at once. It takes time and money to get rid of what you don’t really need. Instead, the right way to start is with something small. Something that makes your life better without costing much money or time but gives your life more space.

It’s like how when your home is too small for a real library, how you don’t throw away books; instead you add shelves until the space looks right. And then if later on you find

There is a story in the Bible of Sodom and Gomorrah being destroyed by “rain from heaven”. Soil cement is the modern version of that.

In a wet soil, water can’t evaporate, so it gets cold. In dry soil, water can evaporate, so it gets hot. In the middle, the soil is neither cold nor hot. But in between is a compromise where the soil doesn’t get either cold or hot. It’s just right: not too cold, not too hot.

Water evaporates from soil at a temperature of about 20 C (68 F). So let’s make a concrete mix that will take care of that problem and then make sure there’s a layer of insulation in the form of felt on top to keep it cool when it’s dry and avoid condensation in the summer.

This is a wonderful example of how a simple mistake can have a big impact. The trouble is that the question is really: what does the earth need?

Earth needs soil. It has many wonderful things for us to do with it, but we don’t want to make it into soil cement. And yet we do want to build our homes out of it, and we do want to do things like grow food in fields on it and hunt animals on it.

Earth needs dirt. We don’t need to call it dirt any more than we need soil cement. But we do want to get rid of the dirt, so that we can use the earth for building our houses and for growing food in fields. So we make something that looks like dirt but isn’t quite dirt, and then we use it instead of real dirt.
