Membrane sheets are used to protect roofs foundations basements terraces and other concrete structures from rainwater and moisture. They create a protective layer over the prepared surface and are available in different materials thicknesses and application methods.
For construction projects in Attock you can choose from APP modified bitumen membrane SBS membrane self adhesive membrane and PVC membrane. Unicorn Chemical provides membrane sheet products and installation solutions for residential commercial and industrial projects.
What Is a Membrane Sheet
A membrane sheet is a flexible construction material installed over a prepared surface to reduce water penetration. Bituminous membranes normally contain modified bitumen with a reinforcement layer that provides strength and flexibility.
APP membrane is commonly used on exposed roofs because it offers good heat and UV resistance. SBS membrane provides greater flexibility and can be suitable for structures where movement is expected. Self adhesive membrane provides a cold application option for selected projects.
Membrane Sheet Length Width and Thickness
Membrane roll dimensions vary according to the manufacturer and product range. A common bitumen membrane format is approximately 1 meter wide with a roll length of 10 meters. Some products are also available in 15 meter rolls.
Common thickness options include 2mm 3mm and 4mm. For many roof applications 3mm and 4mm sheets are selected. Unicorn Chemical lists APP torch membrane in 3mm and 4mm options with a 1m x 10m roll format. The correct thickness should be selected according to the surface condition exposure and project requirements.
Membrane Sheet Price in Attock
The membrane sheet price depends on thickness membrane type brand quality roll size transportation and installation requirements. A July 2026 market estimate lists 3mm APP membrane at around Rs 3500 to Rs 5000 per roll. The estimated price for 4mm APP membrane is Rs 4500 to Rs 6500 per roll. SBS membrane is around Rs 5000 to Rs 7500 per roll while self adhesive membrane is around Rs 4000 to Rs 7000 per roll. These are general market estimates and the actual quotation can vary according to supplier location material grade and project size.
A current Attock service listing gives different local estimates of Rs 4500 to Rs 7000 for 3mm membrane and Rs 7000 to Rs 12000 for 4mm membrane. This shows why it is important to confirm the exact product specification before comparing prices.
Installation may be charged separately. Surface preparation primer labour transportation joint treatment and additional detailing can affect the final project cost.
Types of Membrane Sheets
APP Modified Bitumen Membrane
APP membrane is widely used for exposed roofs terraces and concrete surfaces. It is generally installed using the torch on method and is suitable for areas exposed to heat and sunlight.
SBS Modified Bitumen Membrane
SBS membrane contains a flexible polymer modification. It can be considered for basements foundations retaining walls podiums and other structures where flexibility is important.
Self Adhesive Membrane
Self adhesive membrane has an adhesive backing and does not normally require torch heating. It can be useful for selected projects where open flame installation is not preferred.
PVC Membrane
PVC membrane is a synthetic sheet used for specialized construction applications. Depending on its specification it can be used for roofs foundations water containment areas and other structures.
Where Membrane Sheets Are Used
Membrane sheets can be used in homes shops offices factories warehouses and other buildings. Common applications include concrete roofs terraces balconies basements foundations retaining walls underground structures parking areas podiums and selected water containment structures.
A membrane system is especially useful where the concrete surface is exposed to regular moisture. Before installation the roof or structure should be checked for cracks loose material uneven sections and drainage problems.
Benefits of Using a Bitumen Membrane
A properly installed membrane creates a continuous protective layer over the prepared surface. It helps reduce moisture penetration and protects concrete from prolonged water exposure.
Other benefits include good flexibility strong bonding when correctly installed and suitability for different construction applications. The correct membrane type and thickness should be selected according to the surface and expected exposure.
Membrane Sheet Installation in Attock
Installation begins with cleaning and preparing the surface. Dust loose particles and damaged material should be removed. Cracks and surface defects should be repaired before primer and membrane application.
For torch applied membrane the rolls are carefully positioned over the prepared surface. Heat is applied to the underside while the sheet is bonded to the substrate. Proper overlap and sealing are important at membrane joints.
Corners drains pipe penetrations edges and termination points also need careful treatment. Good surface preparation and correct application are important for reliable membrane performance.
