Precision Floor Screed Supply in Hemel Hempstead
Premium sand & cement screeds, fibre-reinforced mixes, and thermal underfloor heating screeds custom batched on-site for residential renovations and commercial developments across Hemel Hempstead and Hertfordshire.
Laser-Flat, High-Strength Floor Screeds
We supply high-grade semi-dry sand & cement screeds batched volumetrically directly at your site in Hemel Hempstead. Our screeds provide a perfectly flat, level subfloor ready for laying porcelain tiles, engineered timber, vinyl, carpet, or seamless resin coatings.
Traditional Sand & Cement (1:4 & 1:3)
Standard semi-dry screed mixed with washed sharp sand and high-grade cement. Ideal for bonded, unbonded, and floating floor applications conforming to BS 8204-1.
Fibre-Reinforced Floor Screed
Incorporates polypropylene micro-fibres to minimise plastic shrinkage cracking, improve surface impact strength, and ensure superior edge hold around joints.
Underfloor Heating (UFH) Screeds
Engineered for optimal thermal conductivity. Eliminates air voids around hot water heating pipes to deliver fast, even heat transfer across living spaces.
Retarded / Extended Workability Screeds
Specialist retarder admixtures added on-site keep the screed workable for 8 to 12 hours, allowing screeding contractors to float and finish large floor areas without rush.
Screed Types & Minimum Depth Guide (BS 8204)

| Bonded Screed | Directly bonded to prepared concrete base using slurry primer | 25 - 40 mm | 1:3 or 1:4 Sand & Cement + Polymer / Fibres |
| Unbonded Screed | Laid over a damp-proof membrane (DPM) or separating layer | 50 mm | 1:4 Sand & Cement with Polypropylene Fibres |
| Floating Screed (Insulation) | Laid over thermal acoustic insulation boards | 65 mm (Domestic) / 75 mm (Commercial) | 1:3 or 1:4 Fibre-Reinforced Screed |

Why Choose On-Site Batched Screed?
- Extended Working Times: Retarding admixtures blended into the batch give screeders up to 12 hours of open time for meticulous hand-floating or power-floating.
- Consistent Moisture Calibration: Our volumetric mixer precisely regulates water content, ensuring ideal semi-dry "snowball test" consistency every single batch.
- Integral Polypropylene Fibres: Greatly improves crack resistance, tensile bond, and surface wear resistance.
- Zero Waste: Batch exactly the volume needed to screed your rooms without buying bags or disposing of surplus dry sand and cement.
