Ballast Netting

Pebble ballast is commonly used on modern flat roofs, gulls have taken a liking to the pebbles and have developed the strange behaviour of picking them up in their beaks and dropping them from height onto the ground below. This is a serious hazard and to prevent this from happening 19mm net is installed directly onto the pebbles to cover them completely. The netting is installed in the same way as we would a normal bird net.  The gulls are unable to get to the pebbles and the hazard is prevented.

The net is strong enough to still be walked on over the pebbles.

Birdteq has installed these netting systems on several new building projects.   We use stronger components than would usually be necessary for bird netting installations, that give the netting system more strength.


Our ballast netting systems are installed using high grade materials so the nets do not fail and last for many years. The nets are ultra violet light stabilised to prevent premature rotting and are fitted to A4 stainless steel fixings and wire rope.

Using the right fixings to install the our netting systems is vitally important, should a fixing come out then there is a risk that the system will fail and birds may get through the resulting gap.

Our extensive experience enables us to use the correct fixings in all manner of substrates, from delicate sandstone and the thinnest metal cladding to the thickest I beams and reinforced concrete

Netting Specifications

  • 28mm net


Ballast netting comes in three different colours-

  • Black
  • Translucent

Flame retardant netting is also available.


 How Ballast Netting is Installed

Following a drawn up design of the net installation and the Safety Method Statement and Risk Assessment the Birdteq Installation Technicians will inspect the area to be proofed and, wearing all required PPE, will fit a bird net using the following method-

Specialised intermediate and corner fixings are drilled into the substrate that surrounds the roof ballest, this would be a parapet, fixed slab walkways and/or the building walls. Depending on the type of material the substrate is made of, different fixings will be used.  All fixings accommodate an aperture through which a 2mm or 3mm wire rope will pass. Once the wire rope has been passed through the fixings it is ferruled off at one end and tensioned at the opposite end using a M6 or M8 barrel strainer. The netting is then fixed to the wire rope using a specialised tool called a Hog Ringer.  This delivers a small ring to each square of net and attaches it to the wire.

Nearly all the components to install a netting system are specially manufactured and are only available from bird deterrent suppliers.

Other Types of Netting Systems     

Because of its strength and durability bird netting is not only used as a barrier to stop birds.  The netting is used in other net system installs such as Ballast Netting and netting for fisheries.

Security Netting

We have fitted security netting to the outside retail areas of large stores to prevent goods being thrown over perimeter fencing.  Generally 50mm net is used.

Netting for Ponds and Lakes

To protect fish stocks we install bird netting over ponds and lakes.  Our services are mostly used by fisheries.

Fire Retardant Bird Netting

Fire retardant netting is available for high risk areas.


The Advantages of a Ballast Net Installation

Bird Netting allows whole areas or sections of a building to be walled off, completely excluding pest birds. It is often the most economical way to protect large areas.

Durable, high quality and uv light stabilised.

Different colours to blend against different back drops.

Flame retardant bird net available.

Bird netting is used for other applications such as security, pond protection and ballast barriers.


Maintenance Contracts

A properly installed net will last for many years but unforeseen circumstances may mean certain minor repairs are necessary, this might be due to vandalism, extreme weather conditions (gale force winds can sometimes dislodge the hog rings that attach the net to the wire rope) or even gulls dropping stones onto the netting.

For large net installations we recommend a maintenance contract where we carry out a yearly visit to inspect and if necessary carry out any repairs due to any of the above reasons.
