Who we work with

The scope, the information needed and the programme all change with the client. A tendered contractor package is a different job from a single heated floor, so we handle each one on its own terms.

Screeding services

Screed systems specified around the project.

The system follows the floor construction, the depth available, the programme and the finish going on top — not a catalogue preference.

Technical

How a screed floor is built.

A heated floor is a sequence of connected layers and decisions. This illustration shows a typical flowing-screed build-up; the stages alongside explain how the work moves from substrate preparation to curing and handover.

  1. 01

    Substrate and preparation.

    The slab or base is checked and prepared first: levels taken, debris and laitance dealt with, and any bonding or separating detail decided before anything is poured.

  2. 02

    Membranes and insulation.

    Damp-proof membranes, separating layers, insulation boards and edge insulation set the build-up. They also decide whether the screed is bonded, unbonded or floating.

  3. 03

    Underfloor heating pipework.

    Where the floor is heated, pipework is fixed, pressure-tested and left under test. The layout and required cover above the pipes shape the screed depth.

  4. 04

    Screed placement and cover.

    The screed is placed to the agreed depth, working around and over the pipework so it is fully encapsulated, then finished to the surface regularity the project asks for.

  5. 05

    Curing and drying.

    Curing protection comes first, then drying — a separate and much longer process. Commissioning and the follow-on floor finish both wait on verified readiness, not on a date.

  6. Screed over underfloor heating covers the heated build-up in more detail.

Process

A clear route from enquiry to handover.

  1. 01
    Enquiry
    Area, depth, drawings, build-up and programme dates — whatever inputs exist at that point.
  2. 02
    Technical review
    Suitability, screed system, floor build-up, depth, substrate and site access are worked through before pricing.
  3. 03
    Quotation
    A written price with the assumptions, exclusions and outstanding queries set out in plain terms.
  4. 04
    Programme
    Sequencing agreed around preceding and follow-on trades, phasing and realistic installation dates.
  5. 05
    Installation
    Crew, materials, plant and delivery position organised around the agreed access and work areas.
  6. 06
    Handover
    Drying guidance, completion information and documents so the following trades know where the floor stands.
For main contractors and developers

Built for commercial programmes.

A screeding package has to work inside procurement, site logistics and the wider construction sequence — not just on the floor plan.

Pre-award
Drawings and bills of quantities worked through against tender deadlines, with assumptions and exclusions stated early.
Programme
Phased and sectional installations, agreed dates and sequencing around preceding and follow-on trades.
Site
Access, pump runs, delivery position, parking and congestion, levels and the work areas actually available.
During works
Progress updates, documents, completion information and practical drying guidance for the next trade.

Know what is happening without chasing.

We are building a connected project experience for customers and crews, bringing status updates, documents, photographs and drying guidance into one timeline. The interface shown here is in development; until it launches, project updates continue to be handled directly by the Screeding.com team.

  • The current stage and what happens next.
  • Documents, build-up information and drying guidance in one place.
  • A single timeline from accepted quote through to handover.

Specification & handover

Technical standards and quality.

A screed is judged against the project specification and the finish that follows. That means agreeing depth and surface regularity before installation, then managing curing, UFH commissioning, laitance and moisture verification before the floor is covered.

Depth

Depth follows the build-up.

Screed depth depends on the system — bonded, unbonded or floating — on what sits beneath it, on any pipework being covered, and on the loading the floor has to take. Different screed products carry different minimum depths, so the figure comes from the specification and the manufacturer's data for the chosen system rather than a single universal number.

We review depth, build-up and access before issuing a price, and raise queries where the information isn't yet settled. Screed depth guide

Tolerance

Surface regularity is assessed to the requirement.

Flatness is measured, not assumed. In UK practice, surface regularity is commonly described in the BS 8204 context using SR classifications, assessed with a straightedge across the finished surface. The class that applies is the one written into the project specification.

We work to the tolerance the project asks for and confirm it before installation, so the follow-on floor finish has the surface it was designed for. BS 8204 and surface regularity
