Industrial demolition in Málaga: warehouses, concrete and foundations

What does an industrial demolition contractor in Málaga actually do?

An industrial demolition contractor takes a commercial or industrial structure down to the level the client needs, separates the materials and leaves the site ready for the next phase. In the province of Málaga that typically means steel-framed warehouses on business parks, concrete-block workshops, older multi-storey factory buildings, agricultural sheds, loading bays and the slabs and foundations they stand on.

Derribos Industriales Málaga covers the whole sequence: warehouse and industrial demolition, machine demolition with excavators and hydraulic attachments, breaking out reinforced concrete, removing floor slabs and foundations, loading the rubble and arranging its transport to an authorised facility. What we do not do is draft projects, sign technical reports or apply for permits: those belong to your técnico and to you as the owner or developer. We work from that documentation and coordinate dates with the people who wrote it.

The distinction matters when you compare offers. A demolition quote that also promises the licence, the project and the safety study is either bundling the work of other professionals or skipping it. Ours is limited to execution, which keeps responsibilities clear and lets your architect or engineer stay in charge of the technical side.

How is a warehouse or factory building demolished?

A warehouse is demolished in a fixed order: services disconnected, hazardous materials identified and removed, the building stripped of reusable and separable materials, the structure brought down by machine, and finally the slab and foundations broken out if the brief requires it. Skipping or reordering those phases is what causes contaminated rubble, damaged neighbouring units and stalled sites.

On a typical steel portal-frame building the cladding and roof sheets come off first, then the purlins and frames are cut and lowered in a controlled sequence so that nothing falls outside the work zone. Concrete-block and brick industrial buildings are taken down with shears or a demolition grab, working from the top of the walls downwards. Older multi-storey factory buildings are demolished floor by floor from the top, often with a long-reach machine, which is what the photo of the four-storey building on this page shows.

The guide to warehouse demolition phases and planning goes through each stage, the documents that sit behind it and the decisions you, as client, need to make before the first machine arrives.

Why the concrete under the ground is often the bigger job

On industrial sites the part you cannot see frequently takes more time than the building itself: thick floor slabs, reinforced ground beams, pad foundations, pits, ramps and service trenches. Whether all of that has to come out depends on what the site will become, and that decision belongs in the project, not on the day of demolition.

A new development with basements usually needs everything removed. A plot sold as a clean solar may only need the slab broken and the foundations left where the buyer's project allows it. A yard being reused for storage might keep its hardstanding entirely. Our pages on concrete demolition and on slabs and foundations explain how each element is broken out, and the reinforced concrete techniques guide compares hydraulic breakers, crushers and shears on heavily reinforced sections.

Reinforced concrete is not simply harder rock. The steel has to be separated from the concrete so that each goes to the right destination, which is why a crusher jaw that cuts and frees rebar often produces cleaner material than a breaker alone.

Machine, hand or combined demolition: which method fits?

Most industrial demolition is mechanical, because the scale and weight of the elements make hand work slow and dangerous. Hand demolition still has a role where a machine cannot reach or where the building being demolished touches one that stays: a party wall with a neighbouring unit, an office block attached to a hall, an interior that has to be stripped before the structure comes down.

The choice of machine and attachment depends on height, structure, access and surroundings. A standard tracked excavator with a grab sorts and loads; a hydraulic breaker deals with mass concrete; a crusher or pulveriser handles reinforced elements; shears cut steel sections; and a long-reach or high-reach configuration brings down tall structures from the top without people working at height. The guide to excavators, shears, breakers and high reach explains each tool in plain terms.

When a job needs careful hand work, for instance an interior to be emptied inside a building that stays, our sister site Demolición Interior Málaga explains hand demolition in detail.

What happens to the rubble, and what paperwork comes with it?

Under Spain's waste law, Ley 7/2022, demolition waste has to be sorted rather than dumped as a single mixed load. Since 1 July 2022 non-hazardous construction and demolition waste must be separated at least into wood, mineral fractions, metals, glass, plastic and gypsum, and since 1 January 2024 selective demolition is mandatory. Hazardous materials such as asbestos may never be mixed with anything else.

On our sites that means separate piles for concrete, brick and ceramics, steel, timber and the rest, loaded by fraction and delivered to an authorised waste facility. You receive the delivery receipts for each load, which is the evidence your técnico and the town hall look for when the job closes. The rubble removal and skips page covers loading and transport; the guide to waste rules and who is responsible explains the roles of producer and holder.

Fraction	EWC/LER code
Concrete	17 01 01
Bricks	17 01 02
Mixtures of concrete, bricks, tiles and ceramics	17 01 07
Iron and steel	17 04 05
Wood	17 02 01
Construction materials containing asbestos (hazardous)	17 06 05*

The full list, with the official wording, is in our guide to EWC/LER codes.

When is crushing rubble on site worth it?

Crushing turns clean concrete and masonry rubble into graded aggregate with a mobile jaw crusher, like the machine shown in our photos. It makes sense when there is a large volume of mineral rubble, enough space to set up and stockpile, and a realistic use for the crushed material.

The deciding question is what happens to the aggregate afterwards. If your project can use it as fill or sub-base, crushing reduces the number of lorries leaving the site and the volume delivered to a facility. If nobody can use it, the crushed material still has to leave, and the benefit shrinks. Whether recycled aggregate may be reused on the site is decided by the project and its técnico, not by the contractor. The crushing and recycling service page and the guide to on-site crushing and recycled aggregates set out the conditions.

Crushing also brings dust and noise of its own, so it is planned with the rest of the site's control measures, which the dust and vibration guide describes.

Which permits and safety documents does an industrial demolition need?

In Andalusia the total or partial demolition of a building is generally processed through a declaración responsable filed with the ayuntamiento, following the 2024 simplification decree (Decreto-ley 3/2024), provided the building is not protected or within a protected setting. Protected buildings, protected settings and archaeological zones still need a licencia urbanística. Each town hall specifies the documents in its own ordinance, so your técnico confirms what applies to your municipality.

The technical documentation, a proyecto or memoria técnica together with the safety and waste studies, is drafted and signed by a técnico competente. Under Real Decreto 1627/1997 every demolition has a health and safety study or basic study, and the contractor prepares its own health and safety plan from it. Under Real Decreto 105/2008 the project contains a waste management study, and the contractor prepares the waste management plan for the site. Those two plans are part of our work.

The town hall may also require a deposit or guarantee for construction waste, returned once delivery to an authorised facility is proven; the amount depends on the local ordinance. Our guide to waste deposits in Andalusia explains when it applies, and Demoliciones Málaga has a fuller guide to demolition permits in Andalusia.

What if the industrial building has an asbestos cement roof?

Many warehouses and farm buildings in the province still carry corrugated asbestos cement sheets, known locally as uralita. Those sheets have to come off before any machine touches the structure, and only a company registered in the RERA may remove them, under a work plan approved by the provincial labour authority.

Our business is not RERA-registered. The asbestos removal is carried out by a RERA-registered company working as our subcontractor, which prepares and files the work plan under Real Decreto 847/2026, in force since late October 2026, and removes the material. We coordinate the rest of the demolition around it. The asbestos waste travels separately, is never mixed with other rubble and goes to an authorised manager under code 17 06 05*.

For the asbestos part on its own, our sister site explains asbestos removal in warehouses and industrial buildings, and the blog post on what can go wrong when demolishing a warehouse with an asbestos roof lists the mistakes that stop sites.

Working with developers, investors and owners based abroad

A large share of industrial and commercial property on the Costa del Sol and in the Guadalhorce valley is held by investors, funds or families who do not live nearby. For them the practical questions are who is on site, how progress is reported and how decisions get made at a distance.

• You can write to us in English or Spanish, by e-mail or WhatsApp.
• We can send photo updates at the stages you agree, from strip-out to the cleared plot.
• We coordinate access, dates and site handover with your local técnico, agent or site manager.
• For municipal and tax procedures related to the works, the owner identifies with a DNI, NIE or NIF.
• Waste delivery receipts are collected and sent so that the file is complete when the job closes.

Demoliciones Málaga describes the remote process from the owner's side on its page on managing a demolition from abroad. The industrial demolition contractor checklist on this site lists the points to settle before you sign with anyone.

What drives the cost of an industrial demolition?

The cost of demolishing an industrial building depends on the structure, the materials and the site rather than on floor area alone. We do not publish prices, because two warehouses of the same size can differ widely once the details are known.

• Structure and height: steel frame, block walls, reinforced concrete frames or several storeys each call for different machines and time.
• What lies below: slab thickness, ground beams, pits and foundations, and whether they have to come out.
• Hazardous materials: an asbestos roof adds a separate, regulated phase.
• Access and surroundings: adjoining units, public road occupation, working hours, dust and vibration limits.
• Waste: how many fractions, how much volume, transport distance and whether crushing on site is useful.

The post on what drives the cost of demolishing a warehouse explains each factor. For an orientation figure, the demolition calculator on Presupuesto Demolición gives a rounded band, and its page on industrial demolition cost goes into the pricing logic.
