What happens to the floor when racking is removed, and how anchor removal solves it

When a warehouse changes tenants or its layout is altered, the racking is removed, but hundreds of screws and anchors may remain in the floor. These obstruct forklift traffic, hinder the re-configuration of the racking and pose a risk to day-to-day operations, so they cannot simply be left where they are.

BECOSAN® first assesses the type of anchor and its position in the floor, as not all anchors can be treated in the same way. Where the anchor and the floor allow, we completely remove the metal element by drilling and repair the hole to restore a continuous, robust surface. Otherwise, the anchor is ground down below floor level. Where the work forms part of a complete floor refurbishment, the anchors are removed prior to polishing and the BECOSAN® treatment, so that the repaired areas are integrated into the overall floor finish.

The racking is gone, but part of it is still here. Stay with me and I'll explain how we solve it.

When a warehouse changes tenant or its layout is modified, hundreds of screws and anchors can be left behind across the floor, and leaving them there is not an option. Besides preventing a completely obstacle-free surface, they can interfere with forklift traffic, make a new racking layout more difficult, and become a risk to daily operations.

So, how do we remove them? At BECOSAN®, we first assess the type of anchor and its position in the floor, because not every anchor can be treated in the same way. Depending on the situation, we can work on the anchor to leave it below floor level or remove it completely by drilling. When complete removal is required, we extract the metal element and repair the resulting hole to restore a continuous, resistant surface ready to go back into service.

And when this work forms part of a complete floor rehabilitation, we remove the anchors before polishing and applying the BECOSAN® treatment, integrating the repaired areas into the overall finish of the floor.

The goal isn't simply to remove a screw. It's to leave the previous layout behind and prepare the floor for whatever comes next. If you're preparing a warehouse for a new tenant, a new layout, or a change in machinery, contact the BECOSAN® technical team.

Anchors and bolts left in concrete floors: what we see, why they’re there and what we do

Anchors are usually removed when there is a change of tenant or at the end of a tenancy agreement, during the refurbishment of a warehouse or when its use changes, when replacing shelving or machinery, and to ensure the safety of staff walkways.

Leftover anchors and bolts in concrete floors: what you see, why and what BECOSAN® does
What you see Usual cause What BECOSAN® does
Bolt heads or studs sticking out of the floor Racking, machinery or guards removed without removing their fixings Lowers each fixing below the surface or extracts it by core drilling, then makes good the hole
Forklift or pallet-truck wheels catching on fixings Exposed anchors in traffic routes Removes or lowers every exposed anchor along the route and fills the holes level with the floor
Dozens or hundreds of bolt heads visible after a racking change Fixings from the previous layout left in the slab Clears the area zone by zone; the filler can be pigmented to reduce contrast with the slab
Open holes, loose edges or hollow areas around old fixings Concrete weakened around the fixing, or a fixing removed without a proper repair Checks the concrete around the fixing, cleans and fills the hole, and carries out local concrete patch repair where the damage is wider
Floor must be handed back free of fixings Lease requires the floor in its original condition Programmes the removal by zones to meet the handover date
Rusted or deteriorated anchors Corrosion over time Full extraction by core drilling

Fastenings we remove: shelving anchors, machinery bolts, fixing bolts, expansion anchors, threaded rods and studs, screws, and fastenings for barriers, guards and stops. Each type of fastening is assessed individually to decide whether it should be recessed, extracted or treated as part of a localised repair.

Fixings left behind after machinery has been removed from a factory

Floor fixings left behind after machinery has been removed: who is responsible for removing them?

BECOSAN® UK Ltd removes the fixings left in a factory floor once the machinery has been removed: fixing bolts, threaded rods, studs, expansion anchors and fixings for guards and barriers. Each of these is either ground down below the surface or extracted using a core drill, and the hole is repaired using the BECOSAN® J+C repair kit.

This work is usually required prior to a new production layout, the handover of a leased premises or a complete floor refurbishment. We begin with an assessment of the fixings and the surrounding concrete, and can plan the work in zones so that production can continue where necessary.

To assess the work, we require photographs of the floor, the location of the site, the approximate area and the estimated number of fixings.

Removal Of Pavement Anchorage
Anchor In The Process Of Being Removed

How to remove anchors and bolts from a concrete floor

Step 1 - Assess the floor and fixings

We check the type, depth and diameter of each fixing, the condition of the concrete around it (cracks, chipped edges, hollow areas), the number of anchors, and the future use and traffic on the floor.

Step 2 - Choose the method for each fixing

Each anchor is either sunk below the surface or removed completely.

Step 3 - Sinking or removal

To sink an anchor, we drill a hole next to it so that it can be sunk into the floor. To remove it, we drill a hole using a core bit around the fixing and remove the metal element.

Step 4 - Clean and prepare the hole

Loose materials and dust are removed so that the filler adheres to the sound concrete.

Step 5 - Fill with the BECOSAN® J+C repair kit

The epoxy filler seals the hole and stabilises the treated area to withstand the anticipated traffic. It can be pigmented to reduce the contrast with the slab.

Step 6 - Complete the repairs and surface treatment

If the removal is part of a refurbishment, the next steps involve repairing joints and cracks, removing road markings, polishing and treating the surface with BECOSAN®, which hardens and seals the surface.

Which method is used

Complete or partial removal

BECOSAN® selects the method for each fixing after assessing the anchor and the surrounding concrete. Where the anchor and the substrate allow, we prefer to remove the fixing completely using a core drill, so that no metal remains in the slab. Where complete removal is not suitable – for example, because it could compromise the surrounding concrete – we lower the anchor below the surface. In both cases, the hole is filled using the BECOSAN® J+C repair kit.

Full extraction vs lowering
Aspect Full extraction by core drilling Lowering below the surface
Our approach Preferred where the anchor and the floor allow it Used where extraction is not suitable
How it works The concrete is core-drilled around the fixing and the metal is removed A hole is drilled next to the anchor so it can be sunk into the floor
Metal left in the slab No Yes, below the surface
Hole repair BECOSAN® J+C Repair Kit BECOSAN® J+C Repair Kit
Maintenance Periodic inspection of the filled holes Periodic inspection of the filled holes
When it fits The anchor and the surrounding concrete allow it. It is the method used when the fixing interferes with a new installation, is deteriorated or corroded, or the project requires removing the whole element The anchor is in sound condition and does not interfere with a new installation, or extracting it could damage the surrounding concrete

Wherever the project allows, BECOSAN® recommends complete removal, as this removes the metal from the slab and prevents corrosion or any interference with future installations. Recessing remains an option when the anchor is in good condition and does not pose any obstacle.

Operator Removing An Anchor From The Pavement

Types of anchors we remove

All those that are attached to the floor, such as:

  • Industrial rack anchors
  • Large bolts
  • Machinery bolts
  • Expansion studs
  • Screws

Reasons to remove anchors and screws from industrial concrete floors

There are several circumstances in which a property owner, asset manager or facilities manager requires the removal of embedded anchors and screws from an industrial floor:

  • Tenant changeover and rental agreements. Lease terms frequently require the floor to be returned in its original condition, free of any fixing elements left by the previous occupier.
  • Warehouse refurbishment and repurposing. Reconfiguring a facility for a new operational use requires a clean, obstruction-free floor as the starting point for any rehabilitation programme.
  • Machinery and racking upgrades. Replacing or repositioning industrial racking, shelving or machinery leaves redundant fixing points that must be extracted before new installations can be carried out.
  • Increase in asset value. A concrete floor free of protruding anchors and bolts is easier to maintain, safer to operate and more attractive to prospective tenants, directly impacting the value of the industrial asset.
  • Regulatory compliance. Under the Workplace (Health, Safety and Welfare) Regulations 1992, floors must be kept free from obstructions likely to cause slipping, tripping or other accidents. Protruding anchors and fixing bolts are classified as such obstructions.
Projects

Projects about anchor and screw extractions

We have worked with large national and international companies.

SAINSBURY (UK)
Floor area: 61,500 m² Challenge: Following the complete removal of the previous tenant’s warehouse racking, the concrete floor was left with numerous embedded anchors and bolts that prevented the refurbishment of the slab and delayed the handover to the incoming tenant. In addition, the floor contained cracks, deteriorated joints, epoxy coatings and line markings that had to be removed within a very tight programme. Solution delivered: Systematic removal of the existing anchors and bolts using controlled extraction methods, followed by local concrete repairs to restore a level and uniform surface ready for the remaining refurbishment works. Once the floor had been properly prepared, further repairs were completed before the BECOSAN® treatment was applied. Result: The floor was left completely free of fixing elements and fully prepared for refurbishment. A continuous, safe and uniform surface was restored, allowing handover to the new logistics operator on schedule. The complete refurbishment of the 61,500 m² facility was delivered in 60 days.
PENGUIN RANDOM HOUSE (UK)
Surface area: 3,000 m² Challenge: The facility contained shelving units, mezzanine structures and all associated fixing elements anchored to the concrete floor, preventing handover to the incoming occupier. Work carried out: Dismantling of shelving and mezzanine structures. Extraction of anchors and screws. Sealing of fixing points with BECOSAN® J+C Repair Kit. Complementary industrial floor repairs followed by the full BECOSAN® treatment including grinding, densification and sealing. Result: A fully functional concrete floor delivered ready for new occupancy.
PROLOGIS (UK)
Surface area: 30,000 m² Context: Logistics warehouse undergoing refurbishment following the departure of a previous tenant from the timber industry. Before the facility could be handed over to a new occupier, the concrete floor required comprehensive rehabilitation. The surface showed clear evidence of previous industrial use, including remaining anchors and fixing points left behind after the removal of equipment and warehouse installations. Work carried out: Removal of existing anchors and screws embedded in the concrete floor as part of the preparation works prior to the BECOSAN® treatment. Eliminating these fixing elements restored the continuity of the floor surface and ensured the concrete was properly prepared for the subsequent repair and treatment stages. Result: A 30,000 m² concrete floor fully cleared of fixing elements, with continuity and surface integrity restored. The warehouse was handed over to the incoming tenant on schedule and ready for full refurbishment.

What factors influence the cost of removing anchors

The cost depends mainly on the number of anchors, the type of fixing, the method (lowering or complete extraction), the condition of the concrete around the fixings, and any subsequent repairs, polishing or floor treatment that may be required. Access, working in sections, working outside normal hours and combining the work with other repairs can also affect the scope of the work.

To provide a reliable quote, we need photographs, the location of the site, the approximate surface area and the estimated number of fixings.

When simply removing the anchor is not enough

  • Damaged concrete. Removing an anchor does not repair the weakened concrete surrounding it. Cracked edges or hollow areas must first be repaired locally.
  • Countersunk anchors remain in the slab. Countersinking is not suitable if the anchor interferes with a new installation or is corroded.
  • Indoor use. The BECOSAN® J+C repair kit is recommended for indoor areas only.
  • Visible repairs. The filler can be pigmented to reduce contrast, but the filled holes may still be visible on the surface.
  • Fastenings still in use. We remove the fastenings once the shelving or machinery has been dismantled, not whilst they are under load.
FAQ

FaQ: about our anchors, screws, and other hardware removal service

BECOSAN® UK Ltd removes anchors and bolts from racking on concrete warehouse floors throughout the UK and repairs the holes using its J+C epoxy repair kit. Each fixing is either countersunk below the surface or removed using a core drill, and the work can be combined with the repair of joints, cracks and patches, as well as floor treatment.

Companies specialising in concrete floor repair, such as BECOSAN® UK Ltd, remove the fixing bolts, threaded rods, studs and expansion anchors left behind after machinery has been removed, and repair the holes. When comparing companies, ask whether the repair of the holes and the handover of the floor are included.

Generally, a team can remove and seal several hundred anchors a day. The timetable depends on the number and type of anchors, their depth and the condition of the concrete. On large-scale projects, we work in zones and draw up a timetable following an on-site assessment.

Ye. Where necessary, we carry out the work without disrupting plant operations. The work is organised by zones, using dust extraction systems and, if necessary, outside normal production hours. Feasibility depends on the number of anchors, access, internal traffic and the plant’s safety regulations.

The cost depends mainly on the number of anchors, the type of fixing, the method used, the condition of the concrete and any subsequent repairs required. To provide a quote for the work, we usually need photographs, the site location, the approximate surface area and the estimated number of fixings.

Not always. On many industrial floors, it is sufficient to drive the anchor below the surface and repair the hole. Complete removal is recommended when the anchor interferes with a new installation, is damaged or corroded, or when the project requires the element to be removed entirely.

The BECOSAN® J+C repair kit, a two-component, solvent-free, low-viscosity epoxy filler with some flexibility and a cycloaliphatic hardener. It can be pigmented and is recommended for indoor use only.
