Flint Building Solutions specialises in slab and decking installation across North and Central London. Whether you need a new concrete slab foundation, a garden patio or a stylish timber or composite deck, our team delivers durable, high-quality results built to last.

Concrete slabs form the essential foundation for extensions, garden rooms, sheds and outbuildings. We handle all groundwork including excavation, sub-base preparation, reinforcement and pouring, ensuring a solid, level base ready for construction.

Our slab and decking services include:
• Concrete slab foundations for extensions and outbuildings
• Ground floor slab installation with insulation and DPM
• Timber decking design and installation
• Composite decking (low-maintenance, long-lasting)
• Raised and multi-level deck platforms
• Balustrades, steps and integrated seating
• Patio slabs and natural stone paving

Our decking solutions are perfect for creating outdoor living and entertaining spaces. We use premium timber and composite materials that resist weathering, rot and UV damage, giving you a beautiful deck that requires minimal upkeep.

Every project starts with a site survey to assess ground conditions and drainage requirements. We ensure all groundwork and decking installations meet structural standards and are built on proper foundations.
