At SB Screeding, we understand that a great floor starts long before the screed is poured. Our floor preparation services ensure your subfloor is properly prepared for a long-lasting, high-quality screed finish. Operating across the South West of England, including Devon, Cornwall, Somerset, and Dorset, we work with homeowners and builders to deliver precision preparation tailored to your specific project.

 

Why Floor Preparation Matters

Even the best liquid screeds won’t perform to their full potential if the base below isn’t stable, level, or insulated correctly. Poor preparation can result in cracks, uneven surfaces, or screed failure. That’s why we put a strong focus on getting the groundwork right — from clearing debris to installing insulation and vapour barriers with care and accuracy.

 

Our expert team ensures your site is set up for a seamless screed pour. Whether you're working on a new build, extension, or retrofit, our floor prep process eliminates risks, improves screed adhesion, and increases the lifespan of your finished floor.

 

What Our Floor Preparation Service Includes:

• Site Clearance & Base Levelling: We remove debris and high spots on the slab to create a clean, even base.

• Insulation Installation: Rigid insulation boards are installed to enhance energy efficiency and meet building regulations.

• Damp Proof Membranes (DPMs): A polythene membrane is laid over insulation and turned up walls to provide a watertight seal.

• Edge Insulation & Expansion Joints: Expansion strips are fitted along all perimeters, junctions, and doorways to allow for thermal movement and avoid cracks.

• Preparation for Underfloor Heating: If your project includes underfloor heating, we fix the pipework securely over the insulation as part of the prep. You can read more about this on our dedicated Underfloor Heating page.

 

Every step is carried out with precision to ensure that the surface is 100% ready for screeding.
