Leveller Flexi Concrete In Support for Uneven Surfaces, Sheds & Garden Buildings

The Leveller Flexi is a robust, heavy-duty adjustable support system engineered for sheds, garden rooms, timber buildings, and outdoor structures installed on soft ground surfaces. Featuring an integrated ground insert tube for maximum stability, this system provides a fast, reliable alternative to pouring full concrete foundations without extensive groundwork.

Designed for voids between 35-175mm, the Leveller Flexi allows for precise height adjustment on uneven or sloped terrain while improving underfloor airflow to protect timber structures from ground moisture build-up. Tested to support massive loads up to 2500kg per unit, it is built for both domestic and commercial outdoor building projects where ultimate strength is essential.

Manufactured from durable coated steel components, it offers simple fitting into soft ground, with an optional concrete-in setup for permanent, heavy-duty security.
