Whether it’s in residential, commercial, or industrial settings, screed concrete continues to be a reliable choice for achieving a durable and aesthetically pleasing final top layer.
There are three main types of screed concrete: bonded, unbonded, and floating. Bonded screed is directly connected to the concrete subfloor and is suitable for thinner applications. Unbonded screed is laid on top of a damp-proof membrane and is ideal for buildings with damp-prone areas. Floating screed, on the other hand, is unbounded and is commonly used for projects involving underfloor heating or insulated flooring.
Bonded screed is often used in factories and warehouses due to its ability to withstand heavy use and lack of requirement for an aesthetic finish. Unbonded screed, on the other hand, is recommended for basements and areas prone to dampness as it is laid on top of a damp-proof membrane to fight against damp. Floating screed is the best option for projects involving underfloor heating or insulated flooring, improving thermal efficiency.
Bonded screed is directly connected to the substrate, creating a strong structural bond. It is ideal for projects where heavy footfall and constant use are expected, such as in factories and warehouses. Unbonded screed, on the other hand, is laid on top of a damp-proof membrane, serving as a protective layer against dampness. It is commonly used in basements and areas prone to damp problems.
The recommended ratio of cement to sharp sand for screed concrete is 1:3 or 1:4.5. This mixture allows for a strong and stable screed that is suitable for various flooring applications.
Screed concrete provides several benefits, including a level and smooth surface for additional flooring such as laminates, tiling, vinyl, carpets, floorboards, or stone. It also protects the concrete subfloor, withstands heavy footfall, and has excellent insulating capabilities, making it popular for floors with underfloor heating systems.
Floor screeds are commonly used in commercial units, hospitals, schools, housing, and airports. However, they can be used in any setting with internal flooring. Whether it’s a concrete ground floor slab or a precast concrete floor unit, floor screeds are applied to create a smoother and more stable surface for the final floor finish.
