The Thermalite 300mm 3.6N Trench Blocks are a highly effective solution for foundation construction, replacing the need for cavity walls with concrete infill, engineering bricks, or heavy aggregate blocks. Featuring tongue and groove joints with built-in handholds, these trench blocks are easier to handle and install, making them ideal for achieving superior thermal performance. Available in both standard and Hi-Strength (7.3N/mm²) variants, they are moisture-resistant and suitable for use in thin joint masonry, reducing both time and costs. The design eliminates the need for mortar on perp ends, simplifying installation.
