The Thermalite Trenchblock 3.6N 355mm is a versatile foundation solution, replacing the need for cavity walls with concrete infill, engineering bricks, or heavy aggregate blocks. Featuring tongue and groove joints and built-in handholds, this trench block is easy to handle and install, ideal for achieving a 150mm cavity. Available in both standard and high-strength (7.3N/mm²) options, it enhances thermal performance and moisture resistance, making it perfect for below-ground use. Additionally, the design allows for use in thin joint masonry, saving time and resources by eliminating the need for mortar on perp ends.
