Independent Screed Testing for Quality, Compliance & Performance

At UKRS, we provide independent screed testing services to ensure floor screeds meet required strength, moisture, and flatness standards before coverings are applied or the floor is brought into use. Whether for commercial developments, housing schemes, industrial floors, or refurbishment projects, we deliver fast, accurate and reliable testing backed by clear documentation.

Poor or unverified screeds can lead to cracking, failure of floor finishes, disputes, and costly remedial works. Our testing services help identify issues early, verify workmanship quality, and confirm compliance with British Standards and manufacturer requirements.

BRE Drop Hammer Testing (BRE Screed Test)

We carry out BRE testing in accordance with BS 8204-1 & BS 8204-7 to determine screed soundness, compaction and in-situ crushing resistance.
Suitable for:

  • Traditional sand/cement screeds
  • Polymer-modified screeds
  • Calcium sulphate & flowing screeds

Results are clearly classified and reported against the relevant standards.

Moisture Testing (Hygrometer / RH Testing)

Before installing moisture-sensitive floor coverings such as vinyl, wood or carpet, it’s essential to check residual moisture content.

We provide:

  • In-situ hygrometer (RH%) testing
  • Ambient and surface condition checks
  • Reports compliant with BS 8201, BS 8203, BS 5325

CM Moisture Testing (Carbide Method)

The CM test (Calcium Carbide Test) provides a highly accurate and rapid on-site measurement of moisture content.
It is especially effective for:

  • Anhydrite/calcium sulphate screeds
  • Fast-track or early testing situations
  • Areas where RH testing is impractical
  • Manufacturer-specified moisture thresholds

The CM method measures actual moisture content (CM%), giving a reliable indication of whether the screed is ready for floor coverings.
UKRS provides full CM test results, interpretation, and compliance statements based on screed manufacturer limits.

Surface Regularity (SR1 / SR2 / SR3) Testing

Using precision straightedge assessments, we classify the screed surface as:

  • SR1 – High standard (≤3mm deviation)
  • SR2 – Normal standard (≤5mm deviation)
  • SR3 – Utility standard (≤10mm deviation)

Surface regularity is critical for finishes such as vinyl, resin flooring and large-format tile systems.

Screed Thickness Checks, Visual Condition & Defect Assessment

Verification of installed screed depth against project specifications and technical requirements.

We check for common issues including:

  • Cracking
  • Debonding
  • Curling
  • Soft areas and weak surface zones
  • Laitance build-up

Combined with strength and moisture tests, this provides a full overview of screed condition.
