Why this method statement is used

This method statement is used to define and communicate the approved procedure for carrying out method statement: cement–sand floor screed works on site. It ensures the work is planned in advance, the correct resources and controls are in place, and all personnel understand responsibilities, sequence, quality requirements, and safety controls before work begins. It aligns site execution with the documented scope and acceptance expectations.

Who uses this method statement

This method statement is used by contractors, site supervisors, project engineers, QA/QC engineers, HSE officers, consultants, and client representatives. It serves as a shared reference for planning, execution, supervision, inspection, and approval of the activity on site.

When it is prepared and submitted

The method statement is prepared before the work activity starts and submitted as part of the pre-construction documentation package for review and approval.

Who reviews or approves it

The method statement is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the work commences.

Important approval note

This method statement is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all content must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

For example: if your specification requires a departure from a referenced standard, that departure must be documented and approved separately — this method statement will not capture that automatically. Always verify against your applicable drawings, specifications, and regulatory requirements.

  • Weatherproof building envelope or temporary protection in place.

Moisture & DPM

  • Assess base slab moisture. If moisture risk exists, install specified DPM or epoxy moisture barrier compatible with finishes. [Verify]

Benchmarks & Survey

  • Establish primary datum (±0.000) and transfer to each room. Create benchmark marks on walls/columns at ≤10 m spacing.
  • Determine screed thickness from FFL minus finish build-up; confirm minimums by type:
  • Bonded: 25–40 mm typical minimum [Verify].
  • Unbonded (on slip membrane): 50–70 mm typical minimum [Verify].
  • Floating over insulation: 65 mm domestic, 75 mm commercial; with UFH: typically 65–75 mm over pipes or total depth ≥75–90 mm [Verify].

UFH (If Applicable)

  • Heating pipes/cables fixed, pressure-tested (e.g., 6 bar for 24 h, no loss) and maintained under pressure during screeding. [Verify]

Permits & HSE

  • Task-specific risk assessment, permits to work (hot work not expected; verify for cutting/grinding), COSHH/SDS for cement and primers.

Mock-Up

  • Construct a minimum 4–6 m² mock-up to demonstrate mixing, placing, finishing, curing, and achieve SR class; obtain approval before full works.

Method Sequence

StepActivityDescriptionResponsibilityInspection / Hold Point
1 Material receipt and storage Receive cement, sand, primers; verify certificates. Store cement off-ground, sand on clean pad, protect from contamination. Foreman/QA Delivery inspection
2 Pre-start survey & services verification Check area dimensions, FFL, set out bay/joint layout; confirm MEP clearances and UFH readiness. SE/MEP Coord. IR: Pre-pour clearance (HP1)
3 Substrate preparation Shot blast or scarify to CSP 3–5; grind high spots; vacuum to dust-free surface; treat cracks and fill holes with polymer-modified repair mortar; honour structural joints. Foreman/QA Surface profile check
4 Install membranes/insulation/edge strips (as applicable) Unbonded: lay PE slip membrane with 150 mm laps, taped. Floating: install insulation boards flat and tight; install perimeter edge strip continuously at walls/columns; protect penetrations. SE/Foreman IR: Membrane/insulation (HP2)
5 Set benchmarks, pins, and screed rails Transfer datum; set level pins/rails with laser at 1.5–2.5 m grid or as bay size requires; verify thickness vs design; allow for falls where specified. Survey/SE Level check
6 Prepare bonding coat (bonded screed only) Apply SBR-cement slurry (e.g., 1:1 SBR:water; cement to form brushable slurry) or epoxy primer per TDS. Work wet-on-wet: place screed while bonding coat is still tacky/wet. SE/QA IR: Bonding method (HP3)
7 Mixing screed Semi-dry mix in forced-action mixer. Typical ratio: cement:sand = 1:3.5–1:4.5 by weight; W/C ~0.40–0.50 to achieve earth-moist consistency; fibers if specified. Mix 2–4 minutes to uniform color. Pump Op/Foreman Batch control
8 Transport and placement Deliver promptly to workface; spread between rails; compact by tamping/rodding; work from far end to exit; maintain UFH under pressure. Crew Workface supervision
9 Striking off and levelling Use straightedge to strike to rails/pins; close surface with wood float; form day joints at planned locations; install joint profiles where detailed. Crew/SE Flatness checks
10 Finishing After initial set, steel trowel to closed finish if required; avoid over-trowelling that traps water. Provide surface key where bonded toppings specified. Crew Visual
11 Curing and protection Immediately cover with polythene sheeting overlapped/taped for 7 days minimum or apply approved curing compound compatible with adhesives. Prevent draughts and rapid drying; restrict foot traffic for 24–48 h; heavy loads after ≥7 days [Verify]. Foreman/QA Daily curing check
12 Saw cuts / movement joints (if specified) Introduce saw cuts at planned locations once sufficient strength achieved (typically 12–24 h). Depth ~1/3 screed thickness; maintain joint alignment through finishes. SE/Foreman Joint layout verification
13 Initial QA measurements Check thickness using depth probes at not less than 1 point/20 m²; flatness with 2 m straightedge; levels vs datum; record results. QA/QC/Survey IR: Post-place checks (WP)
14 Strength/bond testing (if specified) Prepare cubes/prisms per EN 13892-2 (e.g., 40×40×160 mm) 1 set/200 m² [Verify]; pull-off adhesion tests for bonded screeds at ≥14–28 days. QA/QC/Lab Sample witness (WP)
15 Drying and moisture testing before finishes Allow drying (rule of thumb 1 mm/day to 40 mm then slower; confirm by test). Conduct in-situ RH per BS 8203/ASTM F2170 or MVER per ASTM F1869 at rate ≥3 tests/room or 1/100 m² min [Verify]. QA/QC IR: Moisture test (HP4)
16 Remedials if required Grind high spots; fill low areas with polymer-modified repair mortar; re-test flatness/moisture as applicable; record NCR/CAR closure. SE/QA Re-inspection
17 Handover and protection Install protection boards where heavy traffic continues; issue final acceptance package before flooring works. PM/QA Final IR (HP5)

Frequently asked questions

Typically SR2 (≤5 mm under a 2 m straightedge) is acceptable for many finishes. For high-spec finishes or long corridors, SR1 (≤3 mm) may be required. Verify per project specifications.

Bonded screeds typically 25–40 mm minimum; floating screeds typically 65 mm domestic and 75 mm commercial. With UFH, total depth and cover increase. Verify per project requirements.

Only after achieving SR/level tolerances and acceptable moisture (e.g., ≤75% RH for resilient/wood per BS 8203). Perform in-situ RH or MVER tests and obtain approvals.

Polypropylene microfibers (e.g., 0.9 kg/m³) can reduce plastic shrinkage cracking but do not replace structural reinforcement or movement joints. Use only if specified.

By mechanical preparation (CSP 3–5) and a compatible bonding coat (SBR-cement slurry or epoxy primer). Place the screed wet-on-wet over the bond coat unless the TDS states otherwise.
