Membrane Sheet in Mardan is used to create a protective barrier over roofs, terraces, basements, foundations and other concrete structures. Bitumen membrane systems are supplied in different thicknesses and formulations so the material can be selected according to the building condition and exposure. APP and SBS modified membranes are commonly available for different construction requirements.
Understanding Membrane Sheet
A membrane sheet is a factory manufactured sheet made from modified bitumen with a reinforcing layer. It is supplied in rolls and installed over a properly prepared surface. Torch applied products are heated and bonded to the substrate while the overlaps are sealed to form a continuous protective layer.
These systems are suitable for residential buildings, commercial properties, warehouses and industrial structures. Membrane based systems can also be incorporated into new construction and renovation projects where protection from moisture penetration is required.
Membrane Sheet Length Width and Thickness
Membrane dimensions vary according to the manufacturer and product range. A common roll size is approximately 1 meter wide and 10 or 15 meters long. Common thickness options include 2mm, 3mm and 4mm. Some manufacturers also offer SBS membranes in 3mm and 4mm while self adhesive products can have different thickness specifications.
The right thickness should be selected according to the application rather than choosing the thickest product automatically. Roof exposure, substrate condition, traffic and protection layers can all affect the required specification.
Membrane Sheet Price in Mardan
The Membrane Sheet Price depends on the type, thickness, brand, reinforcement and roll size. A published 2026 market estimate places 3mm APP membrane around Rs3500 to Rs5000 per roll and 4mm APP membrane around Rs4500 to Rs6500 per roll. SBS membrane is estimated around Rs5000 to Rs7500 per roll while self adhesive membrane can range from Rs4000 to Rs7000 per roll. These are indicative market prices and the final rate can vary by supplier, transportation and quantity.
The complete Membrane Sheet Cost may also include primer, surface preparation, crack repair, labour, detailing and protective layers. A site assessment can help establish the actual quantity and installation requirements.
Types of Membrane Sheets
APP Modified Bitumen Membrane
APP membrane is commonly selected for exposed roof applications because it is designed to handle heat and weather exposure. It is available in different thicknesses and surface finishes.
SBS Modified Bitumen Membrane
SBS membrane provides greater flexibility and can be considered for foundations, basements and areas where structural movement needs to be accommodated. SBS torch membranes are available in several thickness options.
Self Adhesive Membrane
Self adhesive membrane has an adhesive backing and is installed without the same torch application process used for conventional torch membranes. It can be considered where open flame application is unsuitable.
PVC Membrane
PVC membrane is a synthetic sheet system used for selected roofs, foundations, water containment structures and specialized construction applications. Product selection should be based on the project specification.
Where Membrane Sheets Are Used
A bitumen membrane can be used on RCC roofs, terraces, balconies, basements, foundations and retaining walls. It can also be used for podiums, parking areas, industrial buildings and selected underground structures.
For exposed roofs the membrane finish should be selected according to weather and surface conditions. Underground applications may require additional protection and drainage arrangements around the membrane system.
Benefits of Using a Bitumen Membrane
A properly installed membrane provides a continuous sheet based barrier with consistent factory controlled thickness. Reinforcing materials can provide strength and dimensional stability while the modified bitumen compound provides moisture resistance.
Important benefits include:
- Consistent sheet thickness
- Different thickness and membrane options
- Suitable for roof and below grade applications
- APP options for exposed roof areas
- SBS options where flexibility is important
- Suitable for renovation and new construction
- Can be covered with protective screed where required
Membrane Sheet Installation in Mardan
Installation starts with inspection and preparation of the substrate. The concrete surface should be sound, clean and free from loose particles. Cracks, damaged areas and drainage problems should be addressed before the membrane is applied.
For torch applied systems the prepared surface is normally primed before the membrane rolls are positioned. The underside of the sheet is heated and bonded to the substrate while the side and end overlaps are sealed. Corners, parapets, drains and pipe penetrations require careful detailing because these areas can become weak points if they are not treated correctly.
Proper surface preparation and installation are important for achieving the expected performance of a membrane system.
