Stairs
The huge advantage of terrazzo stairs is not only a wide selection of variants, but also their particular production. We are able to offer precise shapes and patterns according to the needs of each building.
Stairs and other terrazzo products are manufactured and delivered according to the standard ČSN EN 13 748 - 1.2.
Quality of terrazzo stairs
- Weight is about 30 kg/rm (running meter)
- We can also produce stairs or terrazzo products of special shapes and sizes - custom made
- Products can be made of the grey and white cement, coloured according to requirements of the mass
- Products can be manufactured in special terrazzo designs according to customer specifications – confirmation of physical samples.

Surface treatment
- Grinding - you need to specify individual ground surfaces, other required chamfering.
- Products are not impregnated at the factory.
- The cover of reinforcement by 4 mm diameter, BSt 500, is at least 10 mm.
- Blasting - for outdoor stairs.
Anti-slip modifications of stairs´ treads
Anti-slip adjustment of stairs´ treads - according to the customer's request, we perform the following anti-skid adjustments of stairs´ treads. For outdoor stairs, we perform full-surface blasting of the stair tread surface.

















Technical conditions for mounting the stairs
Technical conditions for mounting the stairs
It is recommended that you carry out the steps of the staircase by a specialist company who knows the artificial stone system (based on DIN 18333 - Artificial stone work) and uses the following principles for the installation of terrazzo stairs and window sills.
Prior to installation, we recommend that the pallets of the terrazzo elements on the site be opened before gluing = removing the cover sheet.
Such unpacked pallets should be stored for about 3-4 days there. At this time tempering of terrazzo elements and compensation of the amount of bound water in terrazzo element occur.
If the elements immediately after unpacking the pallet are glued to a concrete substrate, due to the different moisture on the surface of the terrazzo element, it is possible that the rapidly drying surface shrinks and the terrazzo element is bending. This defect is not a production of terrazzo elements but a mounting error.
Each concrete product expands with heat change. Therefore, it is necessary to comply with the following principles for proper instalation and proper operation:
- Both the stairś cladding and the window sill must not be firmly attached (it must have the possibility of longitudinal thermal expansion)
- Both the stair´s cladding and the parapet board must be laid with a gradient of at least min. 1%% forward to ensure water flow.
- A gap must be left between the stair´s cladding or the window sill and the fixed point (railing, wall, closed staircase) - inside the building about 2mm, outside the building about 5mm - fig.2.
- Both the stair´s cladding and the window sill are laid in the area of tread on mortar strips according to Fig. 1, 3. Mortar for outdoor stairs must be frost-resistant. The angle stair treads are not rubbed and there is an air gap between the stair´s tread and riser.
- The substrate must be cleaned of grease and coarse impurities, must not be crumpled or frozen. Stair treads can be done at an outside temperature above 5 ° C.
- For jointing, cement mortar or grout is used. For outdoor stairs, the grout must be frost-resistant.

Final surface finish before proper use
Terrazzo stairs and sill boards must be impregnated after installation before use (most often after general building clearance, before using the staircase for normal use). This impregnation closes the surface of the terrazzo product, reduces its water absorption and the possibility of fouling of soil into surface pores - reduces the cost of regular cleaning and also highlights the drawing of the aggregate.
Prior to impregnation, the stair and sill surfaces must be properly cleaned. Coarse dirt is removed mechanically - be careful of damage to the surface of the product by scratching with hard materials. Any lime efflorescence or cement or mortar polution is cleaned with cement sludge and effluen removal. Immediately after use of chemicals, the surface must be properly cleaned with clean water. After the surface has dried, the impregnation agent's instructions are to impregnate the surface or fluent the surface of the product. This prevents moisture and dirt from entering the surface layer.
Packing and claiming
Stairs and sill boards are stored on pallets according to dimensions up to the total weight of the palette up to 1000 kg, interlaced with polystyrene cuts, secured with PP tape against displacement and overlapped PVC or stretch foils.
Each palette bears the order label with the number of pieces on the pallet. Handling of pallets is done only with forklifts with carrier forks or loading forks.
Do not stacke pallets! Storage alerts - Product edges are brittle - take extra care when handling and folding on pulling, irreversible edge damage.
Claiming
Product claims must be made in writing prior to its instalatio into the construction site - excluding third party effects. In the complaint, the subject of the claim must be specified in writing. The manufacturer undertakes to initiate a complaint settlement as soon as possible. A solution will be written in which the complaint will be presented.
Pricelist
The final price for a product depends on a number of circumstances - the number of stairs, the shape, the pattern produced, the number of ground surfaces of the element, the fitting, the anchor and others.
