We’re a small, family-run business — I’m Cleo, the owner, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. I work alongside a team of incredibly knowledgeable and caring individuals, and between us we’ve seen a lot of screeding rail systems come and go.

Getting consistent levels in the bedding layer is one of the most critical steps in any paving installation. A bedding surface that varies in depth means the installer has to compensate during laying — which affects the quality of the finished surface and slows the job down. The AZL-EP rails provide the accurate, stable height reference that makes easy and clean screeding possible: set the rails at the required level and the compatible screeding system does the rest. The 25m set is our recommendation for larger paving projects, driveways and commercial work; for smaller areas, the Probst AZL-EP 13m Screeding Rails Set is also available.

“The AZL-EP takes the guesswork out of screeding. Set the rails to the required level, connect them together and run the screeding system along them to create a consistent bedding layer. It’s quicker, repeatable and much easier on the operator than trying to achieve the same accuracy by eye.”

The AZL-EP and EP-UNI — A Purpose-Designed Screeding System

The AZL-EP isn’t just a set of metal rails — it’s a guide system designed specifically to work with PROBST’s hand screeding equipment. PROBST designs the AZL-EP rails and the EP-UNI Screeding System to work together as a matched system. The EP-UNI is specifically engineered to run on AZL-EP rails — its aluminium screeding profile is designed not to leave the rails during use, even when working with large quantities of bedding material. The cubical inclined-plane cross-section of the AZL-EP rail joints makes it impossible for the EP-UNI’s wipers to hook into the joints, giving a clean, uninterrupted screeding pass along the full 25 metres of rails.

Together, the two products give contractors a complete hand screeding system: the AZL-EP provides accurate guidance at the correct level, and the EP-UNI delivers a consistent, level bedding surface across the full working width. Using them as PROBST intends — as a system rather than separately — is what produces the consistent paving levels that make laying straightforward on larger sites.

If you need the EP-UNI screeding tool to go with these rails, it’s available here: Probst EP-UNI Screeding System — 90/230 and 230/300 variants.

Key Benefits for Landscaping and Paving Contractors

• Helps achieve a consistently level bedding layer — the rails give the contractor a fixed guide to screed against, helping create an even, accurate base ready for paving slabs or blocks
• Makes screeding quicker and more straightforward — the integrated plug-in connections allow the rails to be joined quickly, without fiddly separate connectors
• Reduces physical effort — when used with the Probst EP-UNI, the screeding profile runs along the rails, helping contractors maintain a consistent finish without relying solely on manual judgement and effort
• Ideal for larger paving areas — 25m of total rail length across different section sizes (1.5m, 2.5m and 3.0m) gives flexibility when setting up longer runs
• Built for demanding site conditions — galvanised steel construction provides corrosion resistance and durability for repeated use on landscaping and construction sites
• Stable connections maintain accuracy — the cubical inclined-plane joints align correctly and prevent the screeding tool from catching on the connections, helping maintain a smooth screeding run
• Reusable across multiple jobs — a purpose-designed rail system that can be set up, dismantled and reused, rather than improvising from whatever materials happen to be on site
• Can improve the overall quality of the finished installation — a more consistent bedding layer gives the paving installer a better starting point, making the subsequent laying of blocks or slabs easier and more uniform

Who Uses the Probst AZL-EP 25m Screeding Rails?

Block Paving Contractors

Block paving contractors use the AZL-EP rails to set consistent screeding levels for bedding sand before laying blocks across larger areas. The 25m rail set provides enough total length for larger runs and wider working areas, and the plug-in assembly means sections can be set up, moved and repositioned quickly as work progresses across the site.

Landscaping & Hard Landscaping Contractors

Landscaping contractors working on larger patios, terraces, paths and commercial garden paving schemes use the AZL-EP 25m set where a greater total rail length is needed to cover the working area. The combination of 1.5m, 2.5m and 3.0m sections gives flexibility in how the rails are laid out across different-shaped sites. Rather than improvising screed guides from whatever is available, contractors have a reusable, purpose-designed system that can be set up and dismantled efficiently between areas.

Driveway Installers

For larger driveway installations, the AZL-EP 25m provides the rail length to cover a full driveway width and length in fewer setups. Used alongside the EP-UNI 230/300, the system gives driveway installers a repeatable, consistent screeding setup that can be moved section by section as each area of the driveway is prepared.

Commercial Paving & Construction Contractors

Groundworks and commercial paving contractors use the AZL-EP 25m where larger quantities of bedding material need to be screeded to consistent levels across commercial paving areas, car parks, access roads and similar sites. The galvanised steel construction and reusable plug-in system make the AZL-EP a practical long-term investment for contractors working at this scale.

Why Use Dedicated Screeding Rails Instead of Improvised Guides?

Setting a consistent bedding level is one of the most important steps in any paving installation. If the screeded surface varies in height, the paving installer has to compensate during laying, which affects the finished result and slows the job down.

Improvised methods — timber lengths, copper pipe, or similar — can work for a single run but are difficult to hold at a consistent height and can flex or shift under the weight of the screeding tool. Purpose-built screeding rails like the AZL-EP are designed to provide a rigid, stable height reference that stays in position during use.

The AZL-EP rail joints use a cubical inclined-plane cross-section that creates inclined rail joints in each direction. This makes it impossible for the wipers on compatible PROBST screeding tools to hook into the rail joints during use, giving a clean, uninterrupted screeding pass across the full length of the rails. That’s a detail that improvised guide rails simply cannot replicate.

Frequently Asked Questions about the Probst AZL-EP Screeding Rails

I’m Cleo, owner of The Paving Experts, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. I work alongside a small team of incredibly knowledgeable and caring individuals who share the same passion for getting it right. The FAQ answers below come from the questions we’re asked every single day.

What are PROBST AZL-EP screeding rails?

PROBST AZL-EP screeding rails are professional galvanised steel guide rails designed to provide accurate guidance for hand screeding systems when preparing bedding or subgrade surfaces for paving. When set at the required level, the rails allow easy and clean screeding across the working area. They are designed for use with the PROBST EASYPLAN EP-UNI, TELEPLAN-TP and FIXPLAN FP hand screeding systems.

What are AZL-EP screeding rails used for?

AZL-EP rails are used as guide rails for PROBST hand screeding systems. When set at the correct height, they provide accurate guidance that allows easy and clean screeding of bedding material across the working area — helping contractors establish a consistent, level bedding surface before laying paving slabs, blocks and other paved surfaces.

What is included in the AZL-EP 25m set?

The 25m set includes 10 rail sections: 2 × 1.5m, 4 × 2.5m and 4 × 3.0m galvanised steel rails. Total weight is 41kg. Order number is 51000057.

What is the difference between the 13m and 25m AZL-EP sets?

The 13m set contains 6 sections (2 × 1.5m and 4 × 2.5m) and weighs 22kg. The 25m set contains 10 sections (2 × 1.5m, 4 × 2.5m and 4 × 3.0m) and weighs 41kg. The 13m set is suited to smaller and medium-sized paving areas; the 25m set is for larger paving projects. The rail material, pipe diameter, connection system and method of use are the same across both sets.

Why are the AZL-EP rails and the EP-UNI used together?

PROBST designs the AZL-EP rails and the EP-UNI as a matched system. The EP-UNI screeding profile is engineered to run on AZL-EP rails and stay in contact with them throughout the screeding pass. The cubical inclined-plane rail joints make it impossible for the EP-UNI’s wipers to catch on the joints, giving a clean, uninterrupted pass. Used together, they provide the accurate guidance and consistent levels that make easy and clean screeding possible.

What screeding systems are compatible with the AZL-EP?

The AZL-EP is PROBST’s dedicated screeding rail kit for the EASYPLAN EP-UNI, TELEPLAN-TP and FIXPLAN FP hand screeding systems.

What is the difference between AZL and AZL-EP screeding rails?

These are two different PROBST screeding rail systems for different tools. The AZL uses a special aluminium profile and is designed for the PROBST TAK and TAS-UNI screeding systems. The AZL-EP uses galvanised steel pipes (26.9mm diameter) and is the dedicated rail kit for the EASYPLAN EP-UNI, TELEPLAN-TP and FIXPLAN FP. If you’re using the EP-UNI, you need the AZL-EP.

What are AZL-EP rails made from?

The AZL-EP rails are made from galvanised steel pipe with a diameter of 26.9mm (1 inch). The galvanised finish makes them non-corroding and suitable for repeated use on site without rusting.

How do AZL-EP screeding rails connect together?

The sections connect using an integrated plug-in system. The connection is non-detachable and allows rail sections to be joined quickly and securely without any additional fixings or tools.

Do the rail joints interfere with the screeding tool?

No — and this is one of the key design features of the AZL-EP. The cubical inclined-plane cross-section creates inclined joints in each direction, making it impossible for the wipers on PROBST’s compatible hand screeding systems to hook into the joints during use. This gives a clean, uninterrupted screeding pass along the full length of the rails.

How do you use screeding rails for paving?

Position the rails at the required bedding height using string lines, a spirit level or existing reference points such as kerbs or paving edges. Once correctly set, place the compatible screeding system onto the rails and pull steadily along to screed the bedding material to a consistent level. After screeding, carefully remove the rails, fill any gaps left and continue to the next section.

How do you set screeding rails for block paving?

Set the AZL-EP rails at the required bedding depth below the finished paving level, checking with a spirit level or string line across the working area. Position them parallel at the correct spacing for the EP-UNI working width, ensure they are stable and secure, then use the EP-UNI to screed the bedding sand to the reference level set by the rails.

How do you get consistent levels when screeding paving?

The AZL-EP is specifically designed to answer this question. Set the rails at the required level — using string lines, a spirit level or existing references — and the rails then provide accurate guidance for the EP-UNI screeding profile, allowing easy and clean screeding across the full working area. The rigid galvanised steel rails hold their position during use, giving a consistent reference height across the entire length of each screeding run.

Why use screeding rails when laying paving?

Screeding rails provide a defined, stable reference level for the screeding system. Without dedicated guide rails it is difficult to maintain a consistent bedding height — particularly across larger areas — which affects the quality of the finished paving surface. The AZL-EP provides accurate guidance that, when correctly set, allows easy and clean screeding rather than relying on improvised methods.

Can the AZL-EP rails be repositioned during a project?

Yes. Once a section has been screeded and paving laid, the rails can be removed, repositioned and reset for the next section. The non-detachable plug-in system makes this quick without any tools.

What is the PROBST AZL-EP order number?

The PROBST AZL-EP 25m Set has order number 51000057.
