A suitable concrete foundation is essential for a stable external oak staircase or balcony. The two common solutions are a reinforced concrete slab or individual concrete pads.
A reinforced slab, typically 100–150 mm thick, provides a level, durable base and keeps the area below the staircase clean and usable. We generally recommend extending the slab 300–400 mm beyond the post footprint where practical.
Individual pads, often around 450 × 450 mm, can be used where a full slab is unnecessary. Their size and depth should be determined by the soil conditions, structural loads and engineer’s design.
For oak staircases and balconies, the foundation should always be designed to suit the posts, loads and ground conditions. Keeping oak posts above standing water is also essential for long-term durability.
At Timber Solution, we prioritize quality by offering larger-sized oak beams for our staircases. Unlike many competitors who use smaller beams and charge more, we focus on robust solutions that guarantee long-lasting strength and stability. Choosing our oak staircases means investing in a durable structure designed to withstand the test of time, providing exceptional value without compromising quality. This commitment to excellence ensures that your outdoor staircase not only looks beautiful but performs exceptionally well.
