Building a natural stone fireplace - stone species, materials, building instructions
In almost every garden there is an ideal place for a home-made fireplace. Such is best located where combustible objects as well as shrubs such as trees, shrubs and other plantings are at least 80 meters away.
Which natural stone types are suitable for the construction of a fireplace?
Before you start building your fireplace, you must first select suitable materials. Not every rock is suitable for such a project, this is especially true for many natural stones. Above all, so-called soft rock - which includes, for example, sandstone, limestone and shale - as well as pebbles have nothing to do in a fireplace. They can explode quickly under the action of intense heat, even explode - and throw their splinters up to ten meters, which, if hit, can cause serious injury. Use hard rock, such as granite or basalt, for fireplaces. Granite, used for such a purpose, but is only suitable for the border.
How to build a fireplace with natural stones
The construction of a fireplace takes about two to three days. This is best planned for a weekend with nice weather - Rainy, humid weather could be problematic later due to the ingress of moisture, in addition, the mortar dries then worse.
materials
On materials you need different natural stones, whichever you want to use. For example, a border of granite stelae looks interesting, some of which are buried in the ground. In this manual, however, we work with cut granite stones, each with an edge length of about 10 centimeters. You need about 300 of them. In addition, you need four bags of refractory cement mortar á 30 kilograms and about 100 kilograms of sand or gravel.
This is how it is built
And this is how the natural stone fireplace is built:
Do not fill the fireplace with pebbles, as is sometimes recommended. These burst very quickly under the influence of heat and are therefore unsuitable for this purpose.
Tips
Before you build and use the fireplace, you should first obtain a permit from your local public order office - the maintenance of an open fire in many German communities for many years, approval and is only allowed at certain times of the year.
