Security Fencing Near Borehamwood
Security fencing is a design problem before it's a materials problem — height, topping, sightlines and what sits either side of the line matter more than the panel you pick.

We're called out for security fencing around Borehamwood regularly, and detailing a security fence junction at a brick pier is usually the first thing we check. The pier's own condition is checked before any bracket is fixed into it, because a soft or spalling pier face won't hold a resin anchor reliably even where the fence design otherwise calls for one. Furzehill Road, Shenley Road BBC Elstree Centre Allum Lane and Furzehill Road plots back onto one another in the estate's original layout. Borehamwood's post-war estates are laid out on a tight grid, with front access generally straightforward but rear access varying by street.
Detailing a security fence junction at a brick pier
Where a fence run meets an existing brick pier, the panel or rail end needs a scribed or bracketed closer rather than a square-cut gap, since an ill-fitting junction at a pier is one of the more common weak points found during a security survey.

Ground conditions and base preparation
Clay ground swells and shrinks with the seasons, which can work a post loose over a few winters if the base wasn't set deep enough to begin with; free-draining ground behaves very differently and usually needs less depth for the same stability.
We test ground on site rather than assume — a boundary that looks straightforward from the surface can hide rubble, old foundations or a high water table that changes how a base is built.
Spigot connections between post and base
A spigot system lets a post be lifted clear of its ground socket for replacement without breaking out the surrounding concrete, which is useful where a vehicle strike or corrosion has damaged one post in an otherwise sound run.
The spigot itself needs to be a snug fit rather than a loose sleeve, because play at that joint under lateral load is what eventually works a socket wider and lets the post rock.
Concrete cure time before a post can be loaded
A post set in fast-setting postcrete can usually take light loading within an hour or two, but a full concrete footing needs several days of cure before it should be relied on for the lateral loading a security fence or gate applies.
Fitting a heavy gate leaf to a post before its footing has properly cured can rock the post out of plumb before the concrete has reached working strength, which is a common avoidable cause of an early lean on a new installation.
Corrosion at ground line on steel posts
The point where a post meets the ground or concrete collar is where corrosion concentrates, because moisture sits there longest and any coating is most easily scuffed during installation.
A sacrificial sleeve, extra coating thickness, or a slight fall on the concrete collar to shed water all reduce this, and it's worth checking on any steel post that's been in the ground more than a few years.
Fire escape routes and non-lockable egress
A secure gate on a fire escape route or final exit path must allow people to get out without a key, even if it stays locked against entry from outside — a simple push-bar or thumb-turn release satisfies this on the inside face.
This is checked against the building's fire strategy before a lockable gate is fitted on any route marked as an escape path, because a fully keyed gate on both faces is a genuine life-safety fault.
Frequently asked
Why should a gate match the fence either side of it?
A gate with different infill or spacing stands out as the obvious weak point, so matching pale spacing or mesh pattern keeps the whole run to one consistent standard. Theobald Street, Allum Lane Elstree & Borehamwood station Whitehouse Avenue has council-maintained hedging along the pavement that narrows the usable frontage.
How do you handle access on a tight or narrow site?
Materials are planned to be carried through rather than dropped at the boundary where vehicle access isn't available.
How do you fit a fence neatly against stepped brickwork?
Infill panels or a scribed timber closer are cut to follow the step on site, since older brickwork steps are rarely uniform enough to use a standard offset. Allum Lane and Furzehill Road plots back onto one another in the estate's original layout.
How do you handle a boundary with existing drainage problems?
We build in a fall away from the post base or a soakaway detail rather than setting posts into ground that regularly holds water.
Do school gates need to be self-closing?
Generally yes — self-closing, self-latching gates are a common requirement on school and nursery boundaries so the gate can't be left open by accident.
Can a taller security fence block CCTV coverage?
It can, so camera angles should be reviewed before increasing fence height or solidity, particularly where the same boundary is relied on for surveillance.
Can deliveries still be received through a fully secured boundary?
Yes, a gate-mounted letterbox or externally accessible parcel box positioned outside the locked line lets deliveries happen without opening the gate.
What holds a site secure while permanent fencing is being installed?
Weighted or ballasted temporary Heras-style panels, properly linked and clamped, are the standard interim measure while permanent fencing is fitted in phases.
That's the standard we hold to on every Borehamwood job — fitting a heavy gate leaf to a post before its footing has properly cured can rock the post out of plumb before the concrete has reached working strength, which is a common avoidable cause of an early lean on a new installation.
