Precision Floor Screed Supply in Rickmansworth
Premium sand & cement screed, fibre-reinforced screed, and thermal underfloor heating mixes custom batched on-site for residential extensions and commercial developments across Rickmansworth and South-West Hertfordshire.
Laser-Flat, High-Strength Floor Screeds
We supply high-quality semi-dry sand & cement screeds batched volumetrically directly on your site in Rickmansworth. Our screeds create the ideal level subfloor for laying porcelain tiles, engineered hardwood, vinyl, carpet, or resin coatings.
Screed Types & Minimum Depth Guide (BS 8204)
| Screed Construction Type | Minimum Depth Required | Key Sub-Base Requirements | Ideal Application |
|---|---|---|---|
| Directly Bonded Screed | 25mm – 40mm | Mechanically prepared substrate with SBR bonding slurry. | Thin-bed domestic renovations, garage resurfacing, heavy commercial traffic. |
| Unbonded Screed | 50mm minimum | Laid over a damp proof membrane (DPM) or separating poly sheet. | Ground-bearing concrete slabs where damp isolation is needed. |
| Floating Screed (over Insulation) | 65mm (domestic) / 75mm (commercial) | Laid over acoustic or thermal rigid insulation boards. | Modern residential extensions, flats, soundproofed multi-storey floors. |
| Underfloor Heating (UFH) Screed | 65mm minimum (≥ 25mm pipe cover) | Compacted tightly around water pipes with thermal conductivity additives. | Warm water underfloor heating installations for maximum heat transfer. |
Why Choose On-Site Batched Screed?
Extended Working Times (Retarders)
Retarder additives can be blended on site into the mixing chamber to give your screeding contractors 8 to 12 hours of workable open time to achieve a flawless, smooth finish.
Integral Polypropylene Fibres
Micro-synthetic fibres disbursed throughout the mix dramatically enhance crack resistance, surface toughness, and flexural tensile strength without requiring crack-control mesh.
Zero Waste & No Heavy Bag Lifting
Forget manually mixing hundreds of 25kg sand and cement bags. We batch precisely the cubic volume you need in minutes directly into your wheelbarrows or pump hopper.
Underfloor Heating (UFH) Thermal Screed Specialists
When screeding over wet underfloor heating pipes in Rickmansworth, proper density and compaction are critical to prevent air pockets that act as thermal insulators. Our specialised UFH screed mixes ensure:
- High thermal conductivity (rapid heat transfer from heating loops into the living space).
- Enhanced flexural strength to withstand cyclic thermal expansion and contraction without cracking.
- Uniform semi-dry consistency that packs tightly around pipe clips without disturbing pipe layouts.
