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 can be selected according to the building type exposure conditions and installation method.

For construction projects in Chakwal you can choose from APP bitumen membrane SBS membrane self adhesive membrane and PVC membrane options. Unicorn Chemical provides membrane sheet products and related 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 of its heat and weather resistance. SBS membrane provides greater flexibility and can be considered for areas where structural movement is expected. Self adhesive membrane offers 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 size is approximately 1 meter wide with a roll length of 10 meters. Some products are available in 15 meter rolls.

Common thickness options include 2mm 3mm and 4mm. For many roof applications 3mm and 4mm sheets are selected. The appropriate thickness depends on the surface condition expected exposure and project requirements.

Unicorn Chemical offers APP torch membrane in 3mm and 4mm thickness with a 1m x 10m roll format. Product selection should always be checked according to the specific application.

Membrane Sheet Price in Chakwal

The membrane sheet price depends on membrane type thickness brand roll size quality transportation and installation requirements. A published 2026 market estimate lists 3mm APP membrane at around Rs 3500 to Rs 5000 per roll. The estimated range for 4mm APP membrane is Rs 4500 to Rs 6500 per roll. SBS membrane is listed around Rs 5000 to Rs 7500 per roll while self adhesive membrane is around Rs 4000 to Rs 7000 per roll. These are indicative market prices and the final quotation can vary by supplier location and material specification.

The total project cost can also include surface preparation primer labour transportation joint treatment and finishing work. For a more accurate quotation the roof or structure should be measured before ordering material.

Types of Membrane Sheets

APP Modified Bitumen Membrane

APP modified bitumen membrane is commonly selected for exposed roofs terraces and concrete surfaces. It is generally installed using the torch on method and is suitable for applications where heat and weather exposure are important.

SBS Modified Bitumen Membrane

SBS membrane contains a flexible polymer modification. It can be used for basements foundations retaining walls podiums and other structures where flexibility is an important requirement.

Self Adhesive Membrane

Self adhesive membrane has an adhesive backing and does not normally require torch heating. It can be useful for selected areas where flame based installation is not preferred.

PVC Membrane

PVC membrane is a synthetic sheet used for specialized construction applications. Depending on the product specification it can be considered 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 Swater containment structures.

Chakwal has a broad construction area covering multiple local government areas including Chakwal Talagang Choa Saidan Shah Kallar Kahar and Lawa.

Before installation the surface should be checked for cracks loose material uneven sections and drainage problems. Proper preparation helps the membrane system bond correctly and perform consistently.

Benefits of Using a Bitumen Membrane

A properly installed membrane creates a continuous protective layer over the treated surface. It helps reduce moisture penetration and protects concrete from prolonged exposure to water.

Other benefits include flexibility good adhesion when correctly installed and suitability for different roof and structural applications. Selecting the correct membrane type and thickness is important for long term performance.

Membrane Sheet Installation in Chakwal

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 positioned carefully 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.

Special attention should be given to corners drains pipe penetrations edges and termination points. These areas need careful detailing because poor joint treatment can create weak points in the membrane system.
