Introduction

Exempt conservatories can benefit a simplified foundation design conditional on the ground conditions being acceptable and the foundation strip being proportioned to ensure acceptable load spread. with a foundation depth in excess of 700mm (to avoid frost heave) a simplified approach permits conservatory contractors to reduce both time and cost in arriving at conservatory base level.

Use

To provide sub structure damp protection where a restricted single brick foundation is used in the construction of an exempt conservatory.
