If you’re planning a construction project of any size, foundations should be first on your list of considerations. That said, where do you start?

For uneven soil and low-load projects, RC Slab Foundations are often a suitable solution. If you’ve come across this style of foundation, but are unsure what it means, we’re here to help.

Read on to discover our brief guide to RC Slab Foundations.

WHAT ARE RC SLAB FOUNDATIONS?

First things first, it’s worth clarifying what we mean when we talk about RC Slab Foundations. Sometimes referred to as ‘Raft Foundations’, RC slab foundations are used to level the ground on which a construction project will take place. They are installed below the entirety of a building, evenly distributing its weight and reducing the pressure placed on the earth below.

As the name suggests RC, or reinforced concrete, makes up the majority of the construction. However, reinforcing steel rods also play a crucial role in the absorption of stress and tension placed on the concrete structure.

WHEN ARE RC SLAB FOUNDATIONS USED?

Typically, RC Slab Foundations are used for situations involving compressible solid or unstable earth. As touched upon above, this style of foundation reduces the stress placed on the ground below, spreading the weight evenly and making it a suitable base to build upon. Raft foundations are usually most suitable for low-load projects, such as single or 2-storey buildings.

That said, it is important to note that there is no one-size-fits-all solution when it comes to building construction and foundation installation. Foundation design is specific to the site in question and the most viable solution will be calculated by an expert. Here at Capital Piling Ltd, we’re able to provide a free quote and a land survey within 24 hours of your calling, which will determine whether your site is suitable for ground beams.

HOW ARE CONCRETE SLAB FOUNDATIONS INSTALLED?

The process of RC Slab Installation is relatively straightforward. That said, it does require professional experience to guarantee a high-quality result. The basic method involves trench excavation and, if necessary, anti-heave installation. Once excavated, steel cages are constructed before being filled with reinforced concrete.

If you’re planning a construction project, and feel that RC Slab Foundations may be the most viable solution, you’ll need to find a high-quality piling and foundation contractor. This will ensure that your raft foundation cost is reasonable and the installation is long-lasting.
