Construction of bath begins with the fact that the place for it and base type is chosen. Concerning the basis it is necessary to be defined at stage of drawing up the project. The base has to transfer to earth foundation loading from all higher designs, protect bath from freezing and surplus of underground waters.

1. Decide on material of which you will build bath – if it is wooden felling or similar materials with small weight, the column base will be ideal. At construction of chopped, frame or stacked bath of advantage of such base are especially clearly noticeable – there is no need to do crossing points between columns. In corners of bath and in those places where special loading is supposed, establish columns from stone, brick or reinforced concrete, 50Х50 cm in size.
2. If the bath is planned rather big by the size, maintain distance between columns no more, than two meters. Under frame constructions with lightweight the section can be chosen not really big. Under shoddy constructions of such assignment sometimes establish the columns from tree which are dried up and processed by anti-septic tank.
3. If soil not especially reliable, but the earth damp and loose, perhaps, suits you the base of tape type. It has simple technology, but material it will be required much, as well as labor costs. At first lay trench with depth of 50-70 cm, obligatory it is lower than frost depth. Fill up bottom with coarse-grained sand on thickness of 15-20 cm.
4. Carry out laying of the base from rubble stone, crushed stone, gravel, blocks from reinforced concrete, the beaten and burned-through bricks on solution from cement and sand. In a couple of hours after solution is filled in in timbering, lay sawdust which can be moistened that the concrete top was humidified on the surface of the base.
5. For low construction more often use the screw base – it well will be suitable for soft unstable soil and construction of construction on the site with considerable level of underground water. Screw piles are the steel pipes having sharp tip and the screw blade which facilitates deepening of piles in soil. Two persons can establish one pile. It is possible to connect them by metal corner or bar from tree.
6. The floating base will be suitable for puchinisty, slabonesushchy, heavy puchinisty soil. For it dig out trench with depth of 60 cm, fill up bottom with sand and crushed stone and spill properly water. So it is necessary to make for material shrinkage. To strengthen the base, connect armature and collect timbering. Some time you keep concrete after filling under wet burlap or damp sawdust.
