Floor drains

All floor drains and floor inspection chambers are made of stainless steel as standard: AISI 304, EN 1.4301 and AISI 316L, EN 1.4404. The type of horizontal or vertical drain depends on the amount of liquid (medium) to be drained and on the design parameters (e.g. ceiling thickness).

The drains are made of sheet metal with a thickness adapted to the type of drain. All elements are welded in argon shielding, then etched and passivated, which ensures high-quality welds.

ADVANTAGES OF STAINLESS STEEL DRAINS

• choice of grating depending on application and load class,
• easy installation,
• thanks to the appropriate siphon design, each drain also serves as an inspection point for the sewage system,
• simple design,
• easy to keep clean.

DESCRIPTION OF INDIVIDUAL ELEMENTS
OF VERTICAL AND HORIZONTAL FLOOR DRAINS

• Bodies – their round shape limits the accumulation of dirt and ensures easy removal. Welded areas are properly ground to eliminate sharp edges. This prevents the possibility of injury during installation or cleaning.
• Grates – available in various shapes, sizes and finishes. Grates are selected according to the load class and installation location of the drain. We offer the following types of grates: lattice – non-slip, ladder, plate and sheet metal – perforated.
• Settling baskets – recommended for use in cases where there are large amounts of solid contaminants in the discharged sewage.
• Strainer baskets – used in the case of small amounts of solid contaminants.
• Siphons – characterised by high functionality and simple operation. They provide easy access to the sewer pipe, quick cleaning and the ability to check the tightness of the installation.

SELECTION OF DRAINS
Drains are selected based on two basic parameters:

1. The amount of wastewater discharged (selection of the appropriate drain diameter, expected flow rate [l/s] and size of the upper part).
2. Size, type and intensity of load (the load-bearing element is a grate which, depending on its type and height, will carry the specified load).

How to install floor drains?
INSTALLATION OF ONE-PIECE DRAINS

1. The sewer connection should be brought to the appropriate height.
2. Place the drain in the drain pipe socket so that the top of the drain is 1-2 mm below the top layer of the floor.
3. Fill the space with concrete.
4. When concreting, do not allow the top of the drain to narrow, and remember to thoroughly fill hard-to-reach areas with concrete.

INSTALLATION OF TWO-PIECE DRAINS

1. We begin installation by embedding the lower part of the drain in the structural layers of the ceiling. The lower part should be embedded in a 15–20 [mm] recess to ensure proper drainage of condensation from the horizontal insulation to the drain.
2. We install damp-proof insulation on the ceiling and secure it with the pressure ring of the lower part.
3. The next step is to position and level the upper part of the drain at the specified elevation. The edge of the upper part of the drain should be 1-2 [mm] below the floor surface.
4. Once the upper part has been stabilised, the remaining floor layers can be installed.
5. Fill the space with concrete.
6. When concreting, do not allow the top of the drain to narrow, and remember to thoroughly fill hard-to-reach areas with concrete.
