How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

Product Overview
125mu (500G) (change with product size)Single Wound Screeding Membrane is a polyethylene barrier sheet designed to provide separation and moisture control beneath sand/cement or flowing screeds.
Its consistent thickness and flexible composition support clean laying across prepared substrates, reducing drag and preventing moisture migration into adjoining materials.
The membrane helps maintain a stable interface between the screed layer and underlying insulation or concrete, supporting predictable drying and surface integrity.
Its tear-resistant structure allows reliable unfolding and positioning during installation while accommodating irregularities in the substrate.
Supplied in 125mu (500G) thickness on a 2m × 100m roll, providing 200m² of membrane coverage.
Features & Benefits
- Moisture control: Helps resist moisture transfer between substrates and screeded layers.
- Separation barrier: Prevents bonding between screed and insulation or structural slabs where a slip layer is required.
- Durable sheeting: Resists tearing during handling, unfolding and placement.
- Clean installation: Single wound roll format supports efficient unrolling across large areas.
- Versatile use: Suitable for domestic and light-commercial screeded floors.
- Roll identification: Supplied in 125mu (500G) thickness on a 2m × 100m roll providing 200m² coverage.
Applications
- Floating screeds: Suitable beneath sand/cement or flowing screeds over rigid insulation.
- Bonded or unbonded screeds: Functions as a separation layer to reduce adhesion or moisture interaction.
- Domestic and commercial floors: Appropriate for a wide range of screeded floor constructions.
- Refurbishment projects: Suitable where substrate isolation or moisture moderation is required.
Installation Guidance
- Substrate preparation: Ensure the base surface is clean and free from sharp debris that may puncture the membrane.
- Unrolling method: Roll out carefully over insulation or concrete, maintaining flat contact without creasing.
- Jointing: Overlap edges by the required distance and seal using approved membrane tape.
- Perimeter detailing: Turn up edges at walls to the required height to maintain continuity of the barrier.
- Important note: Avoid puncture damage and ensure continuity across the entire floor area.
Compliance & Performance
- Material classification: Manufactured from polyethylene suitable for use as a screeding separation membrane.
- Moisture resistance: Provides a controlled barrier reducing moisture interaction between screed and substrate.
- Durability: Maintains integrity when protected within the screed build-up.
- Handling note: Store in dry conditions and protect from direct sunlight prior to installation.
- Important note: Ensure compatibility with the screed type and floor build-up in accordance with installer guidance.
