Technically assess existing concrete surfaces, repair them in accordance with the material and visually reintegrate them.
Restoration of concrete surfaces
Whether your exposed concrete facade has become porous due to acid rain, is flaking or has visible patches that are a thorn in your side: we are happy to help you.
Using suitable methods, we renovate aging exposed concrete surfaces according to your wishes. After we have treated the surface, it will look like freshly concreted again. So that you can enjoy it for a long time, we recommend that you protect the surface with a hydrophobic treatment after renovation.
At a glance
The renovation of concrete surfaces restores damaged, dirty or visually impaired concrete components. The goal is a stable, clean surface that matches the object.
Suitable for owners, administrations, construction managers and planners who want to repair existing concrete surfaces, improve their appearance or prepare them for protective treatment.
Mechanical stress, moisture, frost or previous interventions can damage concrete surfaces.
BKOS prepares the damaged areas, builds them up according to the material and adapts the structure and appearance.The area becomes technically more stable and visually quieter.
Aging, use, construction deposits and weather change the surface.
Cleansing, correction and protection are planned as a coherent process.The concrete surface remains usable and maintains a well-maintained appearance.

Send us photos or project details. We will assess the most suitable method.
Before any renovation, the cause of the damage, moisture and load-bearing capacity must be assessed. Pure cosmetics do not replace structurally necessary concrete repairs.
BKOS works throughout Switzerland for private, commercial and public construction projects. The deployment planning depends on the object, surface, access and appointment window.

Practical expertise
BKOS does not assess concrete surfaces in isolation, but in conjunction with use, protection requirements and desired visual quality.

Renovation makes sense if spalling, open defects, severe weathering, contamination or previous repairs impair the use or appearance. In the event of cracks, corrosion or deeper damage, the technical cause must first be clarified.
Concrete cosmetics primarily improve the appearance of a fundamentally intact surface. Concrete restoration treats damaged areas and restores a suitable substrate; Both procedures are often combined.
This depends on the type of crack, movement, width, moisture and cause. Dormant superficial cracks can be treated differently than active or statically relevant cracks; These require technical clarification and, if necessary, a specialized repair plan.
Not always, but when there is moisture, weather, dirt or heavy use, coordinated surface protection can make sense. BKOS assesses cleaning, renovation and protection as a coherent system.
The price depends on the depth of damage, area, preparation, material structure, accessibility and desired final appearance. Prices per square meter without knowledge of the damage are not reliable; an object photograph or meaningful documentation is required.
