Vacant commercial properties are increasingly being targeted by organised crime — and once a site has been occupied, securing an eviction order can be a long, costly, and legally complex process. For property owners and managers, the smartest approach isn’t reacting after the fact — it’s preventing unauthorised access from happening in the first place.
That’s exactly the brief Blok Logic delivered this week, supplying and installing 10x 5-tonne concrete security blocks (3m wide) to a vacant commercial site in Wigan, protecting it from unauthorised entry while it remains unoccupied.
Why Vacant Sites Need Stronger Security Measures
With a rise in organised groups specifically targeting empty, un-manned commercial properties, standard single-layer concrete blocks are increasingly not enough of a deterrent on their own. Once a site is occupied, landlords and site owners can face lengthy legal processes to regain access — making prevention far more effective (and far less expensive) than the alternative.
In response, we’re seeing growing demand from clients for double-stacked 5-tonne concrete blocks — two full-size blocks positioned securely on top of one another to create a significantly higher, more robust physical barrier against unauthorised access, vehicle incursion, and site occupation.

The Wigan Deployment
For this job, our team delivered and installed 10x 5-tonne, 3-metre-wide concrete blocks, double-stacked around key access points to fully secure the site perimeter.
The deployment made use of:
- Two 32-tonne lorries, transporting the full block order over two trips.
- Our new crane lorry, placing each block into position with pinpoint accuracy
The result: a secure, heavy-duty barrier installed quickly, safely, and with zero disruption — giving the site owner peace of mind that their vacant property is properly protected.
