Concrete Floors Under Screed - Regupol E48

Regupol E48 is an under screed product designed to isolate screeds from the main structure of the building, reducing impact energy generated by general footfall.

Other items required with this product:
High Tack Tape
Poly DPM

• Designed to reduce impact noise from high loads, having a maximum load bearing capacity of 30kN/m(3000kg/m).
• Excellent impact and airborne performance.
• Offers long term performance without collapse or "bottoming" out under high point loads.
• Minimal creep, even under high loads.
• Resistant to ageing and deformation.
• Quick and easy to install. No need for separate perimeter strips.
• Minimises construction heights.
• High quality and exact material thickness guaranteed.
• Suitable for use with underfloor heating.

Before you lay Regupol E48

1. Prepare the Base Floor. It is important that the base floor is Clean (free from loose dirt and concrete dust), Flat (within National Building Standards ±5mm over a 5m span) and where possible, Dry.
   
   
2. Unroll the Regupol. When the product is rolled up it stretches slightly. Unwind each roll where it is to be installed and leave it for a few hours before measuring or cutting to length.
   
   
3. Please check that you have the correct number of Regupol Corner Pieces. One Regupol Corner Pieces should be used for each internal corner.

Laying Regupol E48

1. The Regupol must be laid dimpled side down. Use a sharp craft knife and straight edge for cutting to size.
   
   
2. Position the Regupol Corner Pieces into each of the internal corners, with the bottom folds laid flat on the sub-floor for stability purposes (see Fig. 1).
   
   
3. Unroll a full width piece of Regupol E48 making allowance for the 100mm upturn at each end. Cut a 230mm x 230mm square piece from the Regupol E48 in the corner that will overlap the corner piece. Move the Regupol E48 to overlap the Regupol Corner Piece and turn it up each wall by 100mm. Ensure that all overlapping edges are taped with Regupol Tape (see Fig. 2).
   
   
4. Overlap all joints (both along and across the roll) by at least. 50mm and tape all joints using Regupol Tape only (see Fig.3).
   
   
5. Turn up edges at walls to ensure the screed will not touch the walls and is of sufficient length to lap under wall linings and skirtings (we recommend the length be 100mm) (see Fig.4a).
   
   
6. Lay a waterproof membrane (e.g. Visqueen), minimum of 0.2mm thick over the entire area (see Fig. 4b). Overlap all joints by at least

100mm and tape all joints using Regupol Tape only.
You can now cast the screed taking the usual precautions to avoid damaging or moving the membrane and the Regupol.
