FURNACE FOUNDATION
Furnace foundation is an underground structure usually made out of concrete. This
foundation is a main load-bearing element that allows to transfer the load from the installed furnace
to the foundation (ground).
Foundation for the furnace and separately standing chimney is a single-piece reinforced
concrete structure.

To install the foundation for the furnace with a brick chimney, you should adhere to the following
guideline:
The foundation must only bear the load of the furnace, that's why in case of furnace and wall
foundations closeness to each other they shouldn't be combined. The distance between two
foundations should be 30-50 mm, so they will be able to move freely in the process of their
settlement.
If all of the conditions, such as climatic conditions, type of soil, mass of the construction (for
example, a furnace with a metal chimney and protective shields made of soapstone would
weight not more than 750 kg), satisfy the requirements it is possible to combine two founda-
tions. In this case, draw special attention to the installation of reinforcement cage and
foundations connecting node.
Foundations' width and length are determined in accordance with overall dimensions of the
furnace plus manufacturing clearance, which takes into account the thickness of the
protective shield and all essential clearances. In some cases, it is needed to add 100 mm
around the perimeter of supporting structure for the floor decking.
To prevent bulging, it is recommended to lay the foundation to the soil frost zone according to
the CP 22.13330.2016 “Soil bases of buildings and structures”. Revised edition of Construction
Directives and Rules 2.02.01-83* (With Amendment No.1, 2, 3).
For example:
For Moscow, where the soil type is clay loam, the depth should be 1320 mm
For Yekaterinburg, where the soil type is clay sand, fine and dust sand, the depth should be
2090 mm
Regardless of the construction, the foundation must be damp-proofed at the top edge in
order to prevent the infiltration of ground waters into furnace' brick constructions. For this
reason, the foundation is laid on two layers of hydraulic insulating material.
