Building Preservation

Securing substance, shaping the future.

Buildings and infrastructures must constantly adapt to changing requirements - be it through new uses, energy standards or increased safety requirements. Wayss & Freytag is your experienced partner for the preservation, modernisation and refurbishment of existing buildings.

With technical expertise, precise execution and high standards of quality and sustainability, we ensure that existing buildings remain functional, safe and economical in the long term.

Concrete repair

Value retention for underground car parks and parking structures

Underground car parks and multi-storey car parks are particularly exposed to moisture, de-icing salts and mechanical loads. Concrete repair is crucial here for the safety and service life of the structures. We analyse damage such as cracks, corrosion or leaks and implement targeted measures to restore the load-bearing capacity and durability. This includes reprofiling, crack injections, corrosion protection of the reinforcement as well as floor and wall coatings with chemical and mechanical resistance. Through regular maintenance and early repairs, we extend the service life of your structures and ensure their functionality for future generations.

Revitalisation and conversion

New perspectives for existing buildings

Whether office buildings, commercial buildings or residential properties - we support our clients in the revitalisation and conversion of existing buildings. We develop customised concepts that are functionally convincing. Our services range from the demolition of old structures to structural adaptation and energy-efficient refurbishment. The aim is to open up buildings flexibly for new uses while preserving their value and substance.

Buildings in transition

Refurbishment with expertise

We not only renovate traditional engineering structures, but also water management facilities and building real estate. With our specialised expertise, we ensure that these sometimes sensitive infrastructures are brought up to date technically, functionally and sustainably. The refurbishment of balconies and façades in accordance with current regulations and work on listed buildings are also part of our scope of services.

We attach great importance to energy efficiency when carrying out refurbishment measures: for example, the energy-efficient renovation of façades makes it possible to reduce energy consumption in the long term and at the same time protect the building fabric in the long term. Such investments not only pay off over many years, but also increase the value of the property.
