Thermalite Hi-Strength 7 Trenchblock (Tongue & Groove) (440x215x355mm)

Description

Thermalite Hi-Strength 7 Trenchblock combines high compressive strength with a tongue & groove profile that supports alignment during installation. Integrated handles assist on-site handling and placement.

Suitable for foundation applications with higher strength requirements, these trenchblocks provide structural performance while supporting installation efficiency on site. Classified DS1-4 for resistance to ground contamination, they can be used across a wide range of ground conditions.

Thermalite is recognised as a pioneer of aircrete with its closed micro-cellular structure – formed of millions of tiny, trapped air pockets – which allow for lightweight handling and a favourable strength-to-weight ratio.

Manufactured to BS EN 771-4, compliant with Masonry Wall Robust Details, and supporting Approved Documents Part A, B, E and L, Thermalite keeps programmes on track with straightforward builds and smooth inspections.
