The Nene Valley Stone London brick is part of Forterra’s London Brick range, offering a warm buff tone with subtle colour nuances that bring elegance and sophistication to façades. Its light texture ensures a refined surface that diffuses light gently and softens mortar contrast.

The brick is manufactured via a pressed process with a light texture, giving consistent form and crisp edges while maintaining subtle character. As a facing brick, it’s designed to be the visible external layer of wall construction, combining aesthetic appeal with structural performance.
In terms of performance, Nene Valley Stone carries a durability rating of F1, a water absorption rate of 23 %, and a compressive strength of 25 N/mm². Its standard size is 215 × 102.5 × 65 mm, and it’s frogged with 15–20 % voids. When installed with proper detailing (cavities, flashing, weep holes, good mortar), it offers dependable resilience in UK external conditions.

Frequently Asked Questions
Is Nene Valley Stone London suitable for coastal or highly exposed areas?
Yes — its **F1 durability rating** means it can be used in external settings. In more challenging environments, it's especially important to ensure excellent detailing: good flashing, reliable cavity design, proper mortar, and correct drainage to maintain long-term performance.
How noticeable will the buff tone variation be across a wall?
You’ll see gentle shifts in buff and stone tones across bricks — part of the natural clay effect. To avoid visual banding or patches, it’s best practice to **mix bricks from multiple packs** during installation so the variation is spread evenly across the wall.
Does the 23 % absorption rate risk damp over time?
A water absorption of **? 23 %** is typical for many London Brick products. The real defence against moisture is high-quality installation — proper cavity, flashing, weep holes, and good mortar matter much more than the absorption number alone.
