Mortar Admixtures for RTU and Dry-Silo Applications

• Consistency Across Delivery Systems: Trusted in central batch plants, mobile units (FIBO Collect), and dry-silo-supplied mortar
• Enhanced Workability & Open Time: Supports optimal laying conditions and site efficiency
• Weather-Resistant Formulations: Tailored to withstand delays, temperature swings, and site variables

RTU (Ready-To-Use) mortar is a cornerstone of modern construction — designed for convenience, reliability, and quality. Unlike traditional site-mixed mortars, RTU mortar is pre-batched at controlled facilities, then delivered to site for use via tubs. This streamlined approach eliminates inconsistencies caused by manual mixing, supporting better bricklaying conditions and higher build quality.

Oscrete’s specialist range of RTU mortar admixtures is developed to optimise this process, ensuring that every delivery maintains the right balance of workability, cohesion, water retention, and durability — no matter how it’s produced or placed.

DSM (Dry-Silo) mortar is engineered for convenience, consistency, and quality — making it a trusted choice across today’s construction sites. Unlike traditional site-mixed mortars, dry-silo mortar is delivered in silos, ready to be mixed with water on demand.

This approach eliminates batching errors, reduces waste, and ensures a reliable mortar mix every time improving efficiency and finish across bricklaying, blockwork, and masonry applications.

Want help optimising your DSM formulations with high-performance powdered additives? Oscrete’s technical team is here to support.

RTU & DSM Mortar Delivery Methods

Our admixtures are compatible with all standard production systems in the UK market:

• Central Batch Plants: Where mortar is manufactured in high volumes, Oscrete admixtures help ensure consistency and performance during transport and site storage, even in variable weather.
• FIBO Collect: For mobile batching solutions, such as FIBO collect units, our admixtures deliver predictable flow and finish quality, supporting rapid turnarounds, low wastage, and real-time production control.
• On-Site Silo Systems: Oscrete technologies support mortar mixes prepared and stored in silos, helping manage open time, improve adhesion, and reduce retempering risks.

This flexibility allows producers and site managers to meet demands quickly, whether working on residential developments or large-scale commercial projects.

What RTU & DSM Mortar Needs — and How Oscrete Supports

RTU & DSM mortar must be designed for laying efficiency and site resilience. Factors such as weather exposure, temperature shifts, handling delays, and long days on site all influence the final result. That’s why Oscrete admixtures are formulated to support:

• Workability and flow: A mortar that spreads and finishes smoothly
• Water retention: Critical for extended open time, bonding strength, and bricklaying speed
• Durability: Mortar that sets reliably and performs well in long-term exposure
• Resistance to drying shrinkage and cracking: Enhancing visual quality and structural integrity

Our product range includes plasticisers, water retainers, workability enhancers, and bespoke admixtures for both coloured and natural mortars.

Technical Partnership from Plant to Wall

Every mortar is unique — from site requirements to sand types and cement blends. That’s why Oscrete offers more than just additives: we provide technical expertise, trial support, and mix optimisation to help customers refine their process and deliver dependable mortar performance in every setting.

Whether you’re batching centrally, using FIBO mobile units, or managing silo-based delivery across sites, Oscrete is your partner for high-quality RTU mortar solutions — backed by experience, innovation, and partnership.
