Instarmac joins Gareth Wilson to demonstrate how to build a robust foundation for paving, from assessing the subgrade to constructing a reinforced concrete slab. Discover how climate change can affect subgrades, why concrete slabs are considered ‘almost’ bulletproof, and the key considerations when laying paving onto a slab. The demonstration will also explore the cost implications of concrete slab construction compared with Type 1 and site-batched mixes, alongside top tips for Type 1 and mortar bed construction.
