Arrangement of floors in the washing room takes place in three stages - preparation of the base (lags), laying of the finishing flooring and creating ventilation. The installation process depends on the type of floor chosen - leaking or non-leaking.
Base
For logs, deciduous or pine timber is often selected. The installation of the lag occurs along the width of the room (i.e., the smallest gap between opposite walls). Installation consists of the following steps:
- Installation of supporting chairs in the center of the log (to increase rigidity and stability). Supports are made of wood, brick or concrete.
- Digging a pit for bases 4 cm deep and installing edged board formwork into the pit. On top of the formwork, the 1st layer of concrete + reinforcing mesh + 2nd layer of concrete is laid.
- Applying waterproofing to a concrete site (heated bitumen + a layer of roofing material).
- Preparation of the underground (for leaking floors - 25 cm layer of gravel, for non-leaking - 20 cm layer of expanded clay).
- Digging a pit against the wall in the washroom. The pit walls are compacted and additionally reinforced with clay. A pipe is removed from the pit to drain moisture into a ditch or sewer.
- Laying the first block against a wall opposite the pit. The extreme logs are installed above the rest of the elements to create a slope to the sump.
- Creation of cuts on all logs, except for the extreme ones (subject to a cut of 2-3 mm). The slope of the finished surface is 10 ° (no slope required for leaking floors).
- Compliance with the distance between the logs and the walls of 3-4 cm (to create a ventilation gap for leaking floors).
- Checking the horizontal alignment of the lag using a level (if the horizon is blocked up, the contact areas of the lags with the timber are cut off).
Leaking floor
When laying a leaking floor, an unedged board is taken. Flooring takes place in the following sequence:
- The boards are cut to the size of the room (taking into account the 20cm gap between the flooring and the walls).
- The boards are laid from the wall parallel to the direction of the flooring. The length of the fasteners is selected in accordance with the thickness of the boards.
- Nails are nailed on 1.5 cm indent from the edges of the board (when driving in, they are set at an inclination of 40 °). Fasteners are recessed into the material for 1 mm.
- The rest of the boards are attached at a distance of 3mm from each other.
The boards are covered with two layers of drying oil. It is undesirable to use paint, as it slows down the drying of wood.
Non-leaking floor
A grooved board is suitable for laying non-leaking floors. The arrangement of the flooring occurs in the following order:
- The "black" floor is laid: bars are nailed to the logs 5 * 5cm, on top of which the subfloor boards are laid and fixed with nails.
- A layer of waterproofing (film or roofing material) is laid on the subfloor.
- A layer of thermal insulation is placed. Expanded clay is filled up in the intervals between adjacent logs. The second layer of waterproofing is placed on the insulation.
- Finishing sheet piling boards are mounted (without slots for water drainage). Boards are fastened with nails or bars 2 * 3cm. The bars are fastened with wood grouse screws.
Ventilation
Creating conditions for air circulation between the subfloor and finish floor involves preparing the holes in the floor and securing the pipes. The procedure is as follows:
- When arranging the floor, holes are left in the corners of the washing room for installing ventilation pipes.
- Pipes with a diameter 5-10 cm (made of PVC, asbestos cement or metal).
- After finishing the walls, the pipes are mounted (5 cm specimens can be easily hidden under the cladding).
- Pipes diameter from 5 cm are installed in the corners and attached to the walls with special clamps.
