Blocks and Mortar: The essential duo for smarter, sustainable building
F
or housebuilders and developers, every component counts. From foundation to fi nish, selecting the right
materials can be the diff erence between a project that simply meets expectations and one that exceeds them – economically, environmentally, and structurally. When it comes to blockwork construction, the choice of both blocks and mortar plays a crucial role in delivering performance, sustainability, and long-term value. At Tarmac, we understand that great
construction starts with great materials. That’s why we’ve developed Aggblock Lite and our ready-to-use Tarmac Mortar range – two solutions designed for faster builds, improved sustainability, and exceptional quality.
AGGBLOCK LITE: LIGHTWEIGHT STRENGTH WITH A LOWER CARBON FOOTPRINT Tarmac’s Aggblock Lite is a game-changer in the world of concrete blocks. Designed specifi cally for internal loadbearing and non-loadbearing walls, this medium-density block combines excellent technical performance with impressive sustainability credentials. Manufactured using up to 30% lower
carbon concrete compared to standard blocks, Aggblock Lite supports developers in meeting environmental targets without compromising on strength or durability. Its lower density not only improves handling and speeds up build times on site, but also contributes to better thermal performance and acoustic insulation within the home.
MORTAR: CONSISTENCY, CONVENIENCE, CONFIDENCE While blocks often take the spotlight, the importance of high-quality mortar should not be underestimated. Tarmac’s ready-to-use mortar range ensures that quality is built into every joint. Factory-produced and site-ready, it removes variability, reduces waste, and guarantees consistent performance in all weather conditions. Available in a wide range of colours and strengths, Tarmac Mortar is the trusted choice
for both structural and aesthetic applications. It’s supplied in tubs or silos depending on project size and site requirements, helping reduce mixing time, improve site cleanliness, and speed up the build process. Critically, the use of factory-mixed
mortar improves quality assurance and compliance with NHBC and BS EN standards. It’s also part of a broader drive to reduce labour time and site delays – both vital factors as developers face ongoing skills shortages and productivity pressures.
WHY THE RIGHT COMBO MATTERS Together, Aggblock Lite and Tarmac Mortar create a construction duo that’s hard to beat. Developers benefi t from a lightweight block
that’s easier to handle and faster to lay, paired with a mortar that provides consistency, reduces rework, and minimises waste. The result is higher productivity on site, reduced costs, and a stronger path to carbon reduction. At a time when margins are tight, regulations
are evolving, and consumer expectations are growing, it pays to build smart from the ground up. Whether it’s a multi-phase development or a bespoke one-off , Tarmac’s block and mortar solutions are tailored to help you build homes that last – and stand up to scrutiny in every way.
BACKED BY TARMAC EXPERTISE With over 150 years of materials innovation, Tarmac supports housebuilders at every stage of construction. Our technical teams work closely with developers to specify the right products, optimise onsite performance, and align with modern building regulations. We’re also committed to helping our
partners reach net zero targets, with continual investment in lower-carbon materials, circular economy principles, and product transparency – including an Environmental Product Declarations (EPDs) for Aggblock Lite.
THE SMART CHOICE FOR MODERN HOMES Building better homes starts with smarter materials. By combining Aggblock Lite’s low- carbon, lightweight strength with the precision and performance of Tarmac Mortar, developers can meet today’s challenges – and prepare for tomorrow’s. So, when you’re laying the foundation of your next project, remember: it’s not just about blocks or mortar. It’s about choosing both – wisely.
