Legato® Interlocking Concrete Blocks
Elite are proud to present the ultimate engineered interlocking block – Legato®, the name coming from the Italian for ‘tied together’.
These high strength engineered blocks are cast from concrete which DOES NOT contain any recycled materials they are designed to provide a solution for a huge variety of projects including block wall flood defence, material storage bays (e.g. aggregates, salt, light scrap metals, wood chip, tyres, white goods, bales, RDF waste, black bag waste etc) blast walls, pendine walls, retaining walls, coastal erosion prevention, fire break walls as part of Fire Prevention Plans, counter weights / kentledge, salt storage, silage clamps, industrial buildings and bridge abutments / supports..
They are also suitable for various temporary works for example constructing cofferdams or creating solid barriers between open rail lines and those being replaced thus avoiding the need for disruptive ‘all line blocks‘ by allowing ‘adjacent live line working‘ / A.L.O. (Adjacent Line Open).
Before you start using our blocks we recommend you check out our unique stability and loadings directory below where you will find lots of guidance on wall heights, material storage and ground bearing / foundations etc – there are also great downloads available to assist in designing new stockbay walls (New Stockbay Wall design Guidance for Interlocking blocks) and inspecting existing walls (Stockbay Wall Inspection Guidance for Interlocking blocks) or contact us on 01952 588885 or email sales@eliteprecast.co.uk where we can refer your questions to an experienced third party structural engineer.
Choose Legato® blocks to create fire resistant walls that are incredibly durable and yet quick and easy to install. Call our sales team on 01952 588885 or email sales@eliteprecast.co.uk.
We can provide a full turnkey package of services including design, transport and installation – all available through our approved contractors.
Structural and foundation design reviews for existing and new projects carried out by an independent structural engineer are available on request.
IMPORTANT NOTE:
It is the customer’s responsibility to ensure appropriate structural checks are carried out before any precast concrete products are installed.

Legato® Interlocking Concrete Blocks comply with BS EN 1992-1-1:2004 Design of concrete structures. General rules and rules for buildings.
Elite are the only company in Europe to manufacture engineered interlocking blocks using high strength (50N/mm2) concrete. This allows our Legato® blocks to exhibit extreme levels of durability, combined with the flexibility of having their own cast-in lifting pin. As each standard block will build 1.28m2 of wall, they provide an incredibly quick solution in a wide variety of applications.
In addition, because the blocks do not contain anything other than high quality, locally sourced aggregates and Portland Cement, you can be assured that your investment will last a lifetime.
See below for the full range and specifications.
Legato® Interlocking block range
Our Legato® blocks come in various sizes – including flat top versions – the standard block is an LG8 1600mm x 800mm x 800mm (highlighted in the table below) and weighs in at 2400 kgs.
As each Legato® block has its own lifting pin cast into it – you can easily change the way in which they are configured without the need for specialist lifting equipment or grabs.
Durability, strength and availability are the key features of these blocks and a next-day nationwide service means that you are never more than 24 hours away from taking delivery.

Typical loads… Legato® block walls
1. These loading figures are for guidance only – if in doubt consult a structural engineer.
2 The retained material should be allowed to naturally fall against the wall as it is stacked.
3 These loading tables relate to specific materials with a typical density and angle of repose, stacked to specific heights and slopes.
4 The client should ensure that the walls are built on a suitable base.
5 The density and angle of repose of each material shown are typical values only.
Further Legato® block example calculations can be viewed in our Stability & Loading Calculations Directory.
For more information call 01952 588 885
Important note – prior to lifting older / pre-used blocks check the lifting pin for wear / corrosion and check the block for cracks. If the block is cracked or the pin is worn it could fail when being lifted.
Additional Notes – wind loading can affect the stability of single skin, stand-alone Legato block walls above 4.8m high. If in doubt get it checked by a qualified structural engineer. Direct impact between mobile plant and the block walls is unnecessary and should be avoided as in extreme cases this could dislodge blocks from the wall. If you identify a particular risk then strapping the top layers can help to mitigate the risk (see image below).
Please note the concrete finish of our interlocking blocks is classed as ‘Basic’ in accordance with the 4th Edition of the National Structural Concrete Specification for Building Construction. https://formworkdokauk.com/2019/08/12/a-guide-to-visual-and-architectural-concrete-finishes/ i.e. there are no requirements other than the concrete being adequately compacted to achieve the density and compressive strength required. The Legato blocks have a moulded face and a trowelled face – where appearance might be of concern, the moulded face tends to offer a smoother and more consistent look. Please note that blocks can be easily damaged if impact occurs during construction and Elite cannot be held responsible for damage caused after the blocks have been delivered and signed for by the client.
