Conservation X Priora Block is a permeable block paving option, ideal for contemporary spaces that require a Sustainable Drainage System (SuDS) solution. These blocks feature a striking surface achieved using a mix of natural crystalline aggregates, giving them a granite-look finish. Manufactured in mainland Britain, Conservation X Priora Block is available in Charcoal and Silver Grey from the previous Mistral Priora range, as well as a new Cream colour.
Our market-leading Priora system has been proven over 15 years of successfully installed projects. The innovative nib on the edge of the blocks creates voids through which water falls into a specially prepared sub-base. The nibs interlock to enhance surface stability, providing 40% more interlock than standard blocks. This results in maximum structural integrity and unsurpassed SuDS performance.
Provided the sub-base is installed to Marshalls' specification, Conservation X Priora Block is suitable for all loading requirements.
Conservation X block is also available as a non-permeable option.
Durable: These blocks are designed to withstand all loading requirements.
Versatile: Available in three colours and three sizes, with a textured riven granite-look finish.
Reliable: Marshalls' market-leading Priora system has been successfully used in projects for over 15 years
