It’s a huge decision to start building a new home. You know it will take a long time, and you know that it’s going to be the biggest decision of your life. There might not be another time to do it, so it’s important to do it right the first time. The thing you should remember is that a house is built from the ground up.
That means if something goes wrong in the beginning, it’s going to damage the whole process. Most people think that the entire process starts by building the foundations, and that’s a mistake. It begins even before that. You need to inspect the ground and see what’s underneath the house. A common problem in the UK is ground gasses. Click here to read more.
Having the idea of an invisible gas coming inside your home is not a pretty one. But, you have to take all the things in mind. Potentially harmful substances like radon, carbon monoxide, and methane can enter your home from below, and without you noticing. A great way to combat this is to install a gas membrane.
Protecting your family from ground gases
All of the gasses we mentioned above are dangerous. Carbon monoxide, radon, and methane are known asphyxiants. That means that inhaling them for a longer period can result in suffocation. Not to mention all of the other health risks, of which the most common one is cancer. Most of the time, they are naturally present in the ground.
However, sometimes they can be artificially created. That happens through old mines, old landfill sites, and brownfield sites. That’s why you need to research whether the ground you are building on is safe. In low doses, these substances are not harmful. But, if the land you bought is on contaminated soil, then you need to install a membrane to protect you. View this link for more https://cen.acs.org/articles/83/i40/Membranes-Gas-Separation.html.
Methane, Carbon Monoxide and Radon
The first two are natural compounds found in the soil. It’s a part of the geochemical part of nature and the Earth. However, the main danger from them comes when they get suddenly released. Carbon monoxide is the same thing that goes out of the exhaust pipe and pollutes the environment. It can cause suffocation in a few minutes.
Methane, on the other hand, is extremely flammable. Lighting a match in a methane filled room can cause an explosion. Radon, on the other hand, is an invisible and radioactive gas. It can cause a lot of health complications, of which cancer is the worst. The UK is most at risk, and there are online maps where you can check potentially dangerous areas.
How do gas membranes help?
Membranes are essentially plastic sheets that don’t allow any gas to pass through them. Most of the time, they are installed as soon as the foundation process begins. The good thing about gas membrane installation is that it serves a double function. The membranes also provide isolation against dampness, which helps to avoid moisture. However, if the ground you are building is expected to have some kind of water pressure, then you also need to install a CDS. That stands for the cavity drainage system.
All of these products undergo rigorous forms of testing. There are standards and certifications to prove their quality. That means they are very robust, and they are also durable. Membranes will be useful until the building is still useful. That means for about fifty to seventy years. However, that is true if they are installed correctly.
In case you have this kind of problem, it’s crucial to call professionals who do this type of work. Gas is invisible and can go through all places that are not sealed completely. Usually, there is pipework to be done, and this requires skill. Every sheet needs to be completely sealed with double-sided tape, and another one layered on top of it, overlapping for at least 150 millimeters.
You should also be careful not to puncture any of the sheets. If you do, take another one and replace it. A membrane with a hole will let gas through, so it will no longer be useful.
