Verti-Block | Retaining Wall Solution - Retaining Wall

A retaining system that uses hollow interlocking blocks with a free draining backfill. Exclusively available from Naylor Concrete in the UK.

Designed to meet the highest standards of quality and durability, Verti-Block is a solution for retaining walls, garden terraces, and erosion control applications. Built-in tapered design enables a 4.8 m minimum radius both convex and concave. 

These hollow blocks are perfectly proportioned for the most popular types of landscaping projects, including gravity retaining walls. The hollow design makes it affordable and easy to handle, when compared with traditional solid blocks.

Features and benefits:

1. Superior Design for Enhanced Durability

• Verti-Block is a wet cast product, providing superior durability with an open core structure that ensures excellent drainage. This innovative design reduces material and transportation costs and is less labour-intensive compared to traditional small hand-laid blocks.

2. Flexible and Strong Interlocking System

• The unique male-and-female design of Verti-Block allows for interlocking installation, offering unmatched strength and stability with gravel infill. This design minimises the risk of placement errors, ensuring precise installation every time.

3. Aesthetic and Customisable Finishes

• Available in real stone textures with two different finishes, Verti-Block is not only functional but also aesthetically pleasing. For added customisation, the blocks can be coloured by others, after installation.

4. Efficient and Cost-Effective

• Verti-Block offers a cost-effective retaining wall solution with quick and easy installation, reducing the need for multiple trades traditionally associated with retaining wall construction. Its hollow design ensures proper drainage and eliminates the need for over or under excavation.

5. Long-Lasting and Eco-Friendly

• Designed for a 120-year lifespan, Verti-Block is a sustainable choice with little to no waste. The natural stone finishes are designed to blend seamlessly with the local environment, encouraging the growth of lichens and mosses in the crevices.

6. Technical Support and Design Flexibility

• Naylor Concrete provides comprehensive technical information and support, including downloadable design software. From the preliminary design stage through to construction, Verti-Block offers varied designs and the ability to achieve both gravity and retained systems.

7. Designed To Meet Industry Standards

• Verti-Block has been designed to meet industry standards. Manufactured in accordance with BS EN 15258:2008 – Precast concrete products, BS EN 13369:2018 – Common rules for precast units and Eurocode 7.

Available in 4 different block styles - standard, top, half, and corner, plus extended standard and half versions up to 1500mm deep available on request. Pipe penetrations can also be formed in the units, if required.

Verti-Block is incredibly strong and versatile thanks to its interlocking design. Featuring a male and female style connection, Verti-Block units ensure you'll get a secure fit that guarantees the correct amount of setback on every installation.

It's hollow design saves money by using less concrete and lowering transportation costs too.

Verti-Block units are also incredibly easy to install. Built with landscaping in mind, they're easy to transport and install - even in tight access spots. Blocks can be moved and put into place with smaller equipment; there's no need for heavy machines like a telehandler or crane. The male and female connection also eliminates placement error, ensuring strength and an exact installation every time.

While the hollow nature of Verti-Block makes it cost-effective and easier to handle, it also improves its ability to retain earth. Even in poor soil conditions, Verti-Block can be stacked higher than other blocks without the use of tiebacks or geogrid.

The male and female design of Verti-Block adds a stronger connection than blocks relying on friction alone. The crushed stonefill also interlocks and creates a continuous mass for greater strength.

Best of all, Verti-Block delivers tremendous cost savings. As a hollow block, Verti-Block is lighter, requiring less manpower, equipment, and transport costs.

Verti-Block is ideal for a variety of landscaping projects including residential communities, commercial campuses, schools, parks, gardens, and more. Able to accommodate winding landscapes and even tight curves, Verti-Block is designed to add interest to any landscape while securely retaining earth.

For projects also requiring a privacy wall or traffic barrier, Verti-Blocks allow fencing or railing to be constructed directly on top of the Verti-Block retaining wall. Fencing can be placed right to the edge of the wall for an attractive, continuous appearance.
