A complete material checklist for laying a new patio or decking area - paving slabs, sub-base, concrete edging, jointing and more.
A new patio or deck is one of the most popular garden projects in the UK - transforming an outdoor space and adding usable living area to any home. Whether you are laying natural stone flags, concrete paving slabs or softwood decking boards, getting the material quantities right from the start avoids expensive over-ordering and multiple builder's merchant trips. The sub-base is often the most under-estimated element: a properly prepared MOT Type 1 or hardcore bed is what determines how long your patio lasts, so it is critical to calculate the compacted volume correctly.
This project kit walks you through every material stage in the right order - from paving quantities and sub-base aggregate through to edging haunching concrete, jointing sand and any adhesive or pointing mortar. Enter your patio or deck dimensions once and every calculator in the checklist opens pre-loaded with your measurements. Your progress saves automatically so you can work through each step at your own pace.
Work through these 5 calculators in order. Each one uses your patio or deck dimensions to pre-fill the key inputs - just refine the details and save each result to your project.
