Our Winning Approach

Where Technical Expertise Meets Sustainable Vision

Much more than simple structural dismantling, deconstruction at Demospec is a mastered art: the art of deconstructing intelligently, preserving what can be saved, and reclaiming every possible material. Our specialized teams work with surgical precision in often complex environments: heritage buildings, industrial structures, and densely populated urban areas.
With specialized equipment, state-of-the-art tools, and meticulously planned methods, we provide a responsible alternative to traditional demolition — cleaner, more strategic, and more sustainable.

Orchestrated Operations

A display of strength, precision, and ingenuity where every move counts.
With state-of-the-art equipment and the expertise of our site teams, each operation is executed with meticulous planning and in full compliance with the most stringent safety standards in the industry.
Impressive worksites — flawlessly controlled.

Services

Structural and Civil Dismantling

Structural and civil deconstruction and dismantling involve safely, methodically, and environmentally responsibly taking apart concrete or steel structures.
Whether for civil infrastructure, engineering works, or other large-scale projects, our specialized team carefully plans each step to minimize risks, maximize material recovery, and ensure efficient execution.

Architectural Stripping

Architectural stripping involves the selective removal of all building materials, both inside and out — including partitions, ceilings, floors, ductwork, electromechanical components, exterior cladding, and roofing elements.
These operations prepare the site for renovation, reconfiguration, or building upgrades. This meticulous work preserves structural elements, maximizes material recycling, and reduces environmental impact, all while maintaining a clean and organized worksite.

Complete Building Deconstruction

Unlike traditional demolition, complete building deconstruction is a process that allows for sorting, recycling, and repurposing the maximum amount of materials. This sustainable approach minimizes environmental impact while preparing the site for new projects.

Industrial Dismantling

Industrial dismantling is a complex process that involves the disassembly, removal, or deconstruction of industrial facilities, equipment, or processes, often occurring at the end of their lifecycle or to allow for site redevelopment. This operation requires specialized technical expertise to ensure safety, regulatory compliance, and the recovery of valuable materials.
It is a key step in the redevelopment or repurposing of an industrial site.

Excavation / Backfilling / Compaction

From excavation to final backfilling, every step is carried out with precision and efficiency.

Excavation

We perform soil excavation according to engineering plans, whether for foundations, underground infrastructure, or under-slab electromechanical works. Our modern machinery and expertise ensure precise and safe operations, regardless of site complexity.

Backfilling

After foundation or conduit installation, we backfill using appropriate materials while adhering to technical and environmental standards. The goal: to ensure long-term stability of your structure.

Compaction

Each layer of backfill is optimally compacted to prevent future settlement. Our compaction equipment and quality control guarantee density that meets the highest standards.

Major Projects

Every project demonstrates our commitment to excellence and client satisfaction.
With advanced technologies and deep expertise, we deliver customized solutions that meet your needs while promoting both sustainability and efficiency.
