Zeta Lock paving for heavy traffic application

Brett Landscaping has introduced Zeta Lock, a 16 sided machine lay block paving unit specifically designed for use in areas which need to tolerate heavy traffic loads, such as airports and ports.

Zeta Lock offers a more durable solution in comparison to rectangular blocks as the elastic modulus of the 16 sided interlocking shaped block is significantly greater than the equivalent rectangular units.

This serves to generate a stronger pavement surface interlock - a key benefit which translates into increased levels of structural integrity.

Brett Landscaping is the only UK manufacturer to supply such blocks for machine laying.

Zeta Lock is available in a standard thickness of 80mm with a plan size of 205mm x 102.5mm.

Machine laying enables clusters of 48 blocks to be installed, each cluster covering 1300mm x 940mm to allow for design and installation flexibility.

Half and closure blocks are also available to speed up installation, removing the need for onsite cutting and reducing waste.

Zeta Lock has recently been used at the new Outer Harbour at Great Yarmouth, where 24,000m2 of paving was mechanically laid by Tolly Paving .

of Colchester.

Tolly Paving proposed machine laying the blocks, as opposed to traditional hand lay methods, due to the large quantities of block pavers involved and the tight project timetable.

The speed and efficiency of machine laying Zeta Lock on the project was further enhanced by a pallet and packaging recycling scheme operated by Brett Landscaping, in conjunction with Tolly Paving, which served to reduce on site waste as well as demand for new materials.

Speaking about Zeta Lock, Andrew Gill, Specification Product Manager at Brett Landscaping said; "One of the keys to sustainability is the performance and longevity of products and systems in use.

Zeta Lock has been developed by Brett Landscaping to offer a robust, long-term paving solution for areas which need to withstand continuous heavy use.

According to Government figures, the UK freight market through ports is expected to grow by approximately 3% per annum whilst the UK Air Travel market is expected to grow by approximately 4% leading to a potential doubling of the market over the next 25 years.

As these markets grow, products such as Zeta Lock will become increasingly important in delivering an infrastructure which does not require as much maintenance, repair or replacement.

"The use of machine lay to install Zeta Lock also delivers design, consistency and sustainability benefits in that complex projects can be installed quickly, accurately and with minimal disruption using the 48 block clusters.

This is important for our major national transport hubs, such as ports and airports, which need to remain functional.
