Retaining walls are an increasingly common requirement across residential, commercial and landscaping developments, but the choice of retaining system can have a significant impact on design, installation, site access, cost and the finished appearance.
Verti-Block offers an alternative approach, combining large precast concrete units with an interlocking design to create a practical and versatile retaining wall system. Available in Ireland through Esker Readymix, Verti-Block is suitable for a range of applications, from residential landscaping and terracing to larger commercial developments.
The system uses hollow, interlocking concrete blocks, with the standard unit measuring approximately 610mm high, 1200mm wide and 910mm deep. The hollow construction reduces the weight of the individual unit compared with a solid equivalent, while the core is filled with clean crushed stone to provide additional mass and assist with drainage.
Key feature of Verti-Block is its male-and-female interlocking connection
A key feature of Verti-Block is its male-and-female interlocking connection. As the blocks are stacked, the connection provides a consistent setback and helps to simplify positioning during installation. The system can also accommodate curved wall layouts, with its tapered design allowing both convex and concave curves.
For projects where access is restricted, the installation method can offer significant practical advantages. The blocks can be transported and positioned using smaller equipment, reducing the requirement for larger lifting machinery in suitable applications. This can be particularly beneficial on residential sites, landscaping projects and developments where working space is limited.
One of the key advantages of working with Esker Readymix is the support available before construction begins. The company has an in-house design service, allowing projects to be assessed at an early stage and the Verti-Block system developed to suit the individual site requirements.
Appropriate block configuration
This provides a direct link between product supply and practical installation. Rather than simply supplying blocks, the team can work with contractors, developers and engineers to help establish the appropriate block configuration and installation approach for the proposed application.
Drainage is also an important consideration in any retaining wall project. Verti-Block incorporates crushed-stone fill within the hollow core, allowing water to drain through the structure and helping to manage hydrostatic pressure.
Beyond its structural function, Verti-Block provides a finished appearance that can integrate well into landscaped environments. The face of the block incorporates approximately 55mm of relief, creating the appearance of a traditional stacked-stone wall.
The system is suitable for gravity and reinforced retaining walls, terracing, plantable walls, property dividers and bases for fencing or railings. It’s flexibility also allows walls to follow winding landscapes and tight curves, providing designers with greater scope when working within existing site constraints.
For engineers and contractors considering retaining wall solutions, Verti-Block provides a combination of modular construction, interlocking geometry and practical installation. Backed by Esker Readymix’s in-house design service, the system offers a complete approach from initial project requirements through to supply and installation.
Verti-Block is available in Ireland from Esker Readymix, Esker, Athenry, Co Galway.
