If you don't need to blast, building a home with rock isn't too difficult. Excavators are fortunate to be able to dig through your rock. The most important thing, in my opinion, is to understand the interplay between water and rock. Rainwater seeps through the topsoil and begins to seep into the earth. This is where things can get dangerous for your house. If the soil within reach of the rainwater is made up of compacted gravel or stone, then it's possible that some of this water may not drain away from the property. This leads to erosion and can cause problems with your basement floor or patio.
The best way to avoid this problem is to keep down the amount of water that reaches the ground surface. This means keeping grass short and using porous pavement where possible. Porous pavement allows water to filter through it and not pool under your house.
If you do choose to build on rock, make sure to find out what type of rock it is before you start digging. Some rocks are much harder to work with than others. For example, granite is very hard to cut with conventional tools and will likely require milling equipment for large pieces of furniture. But even though it's hard to work with, granite is still considered rock because it can be used to support structures such as bridges.
Before you start building anything, take a look at the rock structure beneath your feet.
How to Construct a Stone House (For Apocalypses AND Fun)
Because it is so solid, shale is a great rock to create a foundation on in the building industry. Furthermore, unlike clay, it is compact enough to withstand a structural pile without splitting. Its weakness lies in its susceptibility to heat and water, which can cause it to break down over time.
The most common type of shale found in the United States is sandstone, but there are also deposits of siltstone, mudstone, and coal. Shale is a form of sedimentary rock that was once part of a sea floor. As the name implies, it is made up of large sheets of hardened sediment called slates.
Over time, these sediments were deposited in shallow seas or oceans where they were compressed into rock by tectonic plates. Shales can be very thin or very thick; there are even cases where layers of shale have been stacked on top of each other like sheets of paper. Thicknesses range from a few inches to more than 10 feet (300 mm).
There are several varieties of shale. Those used for building purposes must be quite dense since the weight of a structure depends on its mass per unit area. Denser shales contain more glassy particles that result in stronger rocks. On the other hand, less dense shales contain more pores that allow water to seep through them.
The secret to building a house in terrible weather is to finish the foundation and lift the house's plinth off the ground before the start of a long rainy season or weather. However, in wet areas, it is possible that not a single day goes by without rain. If this is the case, you will need to finish the foundation even though you can't work on it for several months at a time.
Also, be sure to check with your local building department about how many floor joists there should be under a roof before you pour the footings. Some communities require that you specify the number of floor joists you intend to use when you apply for a building permit. Others may ask for proof that you've specified the correct number (such as a letter from the manufacturer), but still require you to get them approved by a building inspector before they'll issue the permit.
As long as you follow these simple steps, you should be able to build a house in terrible weather. Now all you have to do is wait for the next storm!
