Concrete Flooring & Underfloor Heating Compatibility

Use Case Concrete Screed
✔ Driveways & Outdoor Surfaces ✅ Best choice for driveways due to its high strength and durability.
✅ Can handle vehicle weight and extreme weather.		 ❌ Not suitable for driveways—too thin and lacks the strength to support vehicles.
✔ Subfloors for Tiling, Wood, or Resin ✅ Can be used as a subfloor, but may require a screed layer for a smoother finish. ✅ Ideal for subfloors—provides a smooth, even surface for tiling, wood, or resin flooring.
✔ Underfloor Heating ✅ Works well, but takes longer to heat up due to higher thickness.
✅ Holds heat for longer once warm.		 ✅ Better for underfloor heating—thinner profile allows for faster heat transfer.
✔ Polished Flooring ✅ Best choice for polished floors—can be ground down and finished for a high-gloss look. ❌ Cannot be polished effectively—too soft and prone to damage.
✔ Commercial & Industrial Spaces ✅ Used for warehouses, factories, and high-traffic areas due to its durability. ❌ Not durable enough for heavy-duty commercial applications.
✔ Interior Home Flooring ✅ Can be used but requires sealing and finishing to avoid dust and wear. ✅ Ideal for interior flooring when covered with tiles, carpet, or resin.
✔ Fast Installation & Drying ❌ Takes longer to dry—can take weeks to fully cure. ✅ Screed dries faster—can be walked on in 24-48 hours.

Concrete Pros

  • Extremely durable—lasts for decades with minimal maintenance.
  • Handles heavy loads, making it ideal for driveways, garages, and industrial spaces.
  • Versatile—can be polished for a high-end finish or left textured for grip.
  • Retains heat well, making it a great option for underfloor heating systems.
  • More resistant to water damage when properly sealed.
  • Cost-effective for large areas as it requires fewer finishing layers.

Concrete Cons

  • Longer curing time—can take weeks to fully dry before being usable.
  • Requires a skilled installer for polishing or decorative finishes.
  • Heavy material—may require additional structural support in some applications.
  • Surface can be cold underfoot without insulation or heating.
  • Prone to cracking if not properly reinforced with expansion joints.

Screed Pros

  • Provides a smooth, even surface for tiling, wood, or resin finishes.
  • Dries faster than concrete—can be walked on in 24-48 hours.
  • Ideal for underfloor heating—thinner layer allows for better heat transfer.
  • Lightweight compared to concrete, reducing load on structures.
  • Easy to level—ensures a seamless, flat finish.

Screed Cons

  • Not strong enough for driveways or heavy load-bearing areas.
  • More prone to cracking if mixed or applied incorrectly.
  • Requires additional sealing or coverings (tiles, wood, etc.) to protect the surface.
  • Limited decorative options—cannot be polished like concrete.
  • Higher cost per m² when using high-performance screeds.

Frequently Asked Questions

🔹 What is the main difference between concrete and screed?
Concrete is a structural material used for heavy-duty applications like driveways and floors, while screed is a thin, smooth layer applied over concrete to create an even surface for finishes like tiles or wood.
🔹 Is screed stronger than concrete?
No, concrete is much stronger and can handle heavy loads. Screed is designed for smoothness rather than strength and requires a solid concrete base underneath.
🔹 Can screed be used for driveways?
No, screed is not durable enough to handle vehicle weight. Driveways should always be built with concrete, which can withstand heavy traffic and weather conditions.
🔹 Which is better for underfloor heating: screed or concrete?
Screed is the better choice for underfloor heating because its thinner profile allows heat to transfer more quickly. However, polished concrete retains heat for longer, making it more energy-efficient over time.
🔹 Can screed be polished like concrete?
No, screed cannot be polished in the same way as concrete. It is softer and more prone to damage. If you want a polished finish, concrete is the better option.
🔹 How long does it take for screed and concrete to dry?
Screed dries faster than concrete and can be walked on within 24-48 hours. Concrete takes much longer, requiring at least 7 days before light use and 28 days for full curing.
🔹 Is screed waterproof?
Standard screed is not waterproof, but special water-resistant screeds are available. Concrete, when properly sealed, is more resistant to water damage.
🔹 Is screed or concrete more expensive?
Screed is usually more expensive per m² because it requires a concrete base and additional finishing. Concrete, on its own, is a more cost-effective option for structural flooring.
