Black polythene damp proof membrane is a heavy-duty moisture barrier material used to prevent water and ground moisture from penetrating buildings, floors, and walls. At CETECH Ghana, our black polythene, polythene rubber, and reinforced damp proof membrane solutions are designed specifically for Ghana’s climate and construction conditions, providing reliable damp proof protection for residential, commercial, and industrial projects.

Primary User Intent: Informational + Transactional

This product page is designed to help Ghanaian builders, contractors, engineers, developers, and property owners understand what damp proof membrane is, how black polythene and damp proof rubber work, and how to select and buy the right damp proof material in Ghana—online or in-store from CETECH Ghana.

What Is Damp Proof Membrane?

A damp proof membrane (DPM) is a waterproof or moisture-resistant layer installed within a building structure to prevent moisture from the ground or external sources from entering floors, walls, and foundations.

Damp proof membranes are essential in Ghana because of:

• High rainfall levels
• High groundwater tables in many regions
• Humid tropical climate
• Soil moisture migration into buildings

Without a proper damp proof membrane, buildings are vulnerable to rising damp, mold growth, weakened concrete, and long-term structural damage.

What Is Black Polythene Used for in Construction?

Black polythene is the most widely used damp proof material in Ghanaian construction. It is made from polyethylene plastic and supplied as rolls or sheets in varying thicknesses.

In construction, black polythene is used as:

• Damp proof membrane under concrete slabs
• Damp proof membrane for walls
• Damp proof course beneath blockwork
• Temporary moisture barrier
• Protective sheeting during construction works

Because of its affordability, availability, and performance, black polythene remains the industry standard for damp proofing in Ghana.

Polythene Rubber and Reinforced Damp Proof Materials

Beyond standard black polythene sheets, CETECH Ghana supplies polythene rubber and reinforced damp proof membranes designed for higher performance applications.

What Is Polythene Rubber?

Polythene rubber refers to damp proof materials where polyethylene is combined with rubber-based compounds or reinforced layers to improve:

• Flexibility
• Tear resistance
• Impact resistance
• Longevity

These materials are especially useful where slight structural movement is expected or where higher durability is required.

Material Composition and Technical Properties

Black Polythene (Polyethylene – HDPE / LDPE)

• Waterproof and non-porous
• Resistant to rot, mold, and bacteria
• Chemically stable in soil
• Available in multiple thicknesses
• Can be made from recycled polyethylene

Damp Proof Rubber (EPDM / Modified Bitumen)

• High elasticity and flexibility
• Excellent crack-bridging ability
• Resistant to UV and temperature changes
• Long service life in demanding environments

Nylon-Reinforced Membranes

• Nylon fibers embedded for tear resistance
• Improved tensile strength
• Better performance during installation
• Reduced risk of puncture during concrete pouring

CETECH Ghana supplies damp proof membranes that may use one or a combination of these materials depending on the application.

Common Thicknesses of Black Polythene Damp Proof Membrane

Thickness is one of the most important selection factors when choosing damp proof material.

Typical Thickness Options in Ghana

• 300 microns (1200 gauge): Standard residential use
• 500 microns (2000 gauge): Heavy-duty residential and commercial use
• 1000 microns and above: Industrial and high-risk moisture areas

Thicker membranes provide higher resistance to puncture and longer service life, especially in aggressive soil conditions.

Damp Proof Membrane Price in Ghana

The damp proof membrane price in Ghana varies depending on several factors:

• Thickness (microns or gauge)
• Material type (polythene, rubber, reinforced)
• Roll size and coverage area
• Import quality and manufacturing standards
• Quantity purchased

Key Pricing Considerations

• Thicker membranes cost more but offer longer durability
• Reinforced or rubber-based membranes attract premium pricing
• Bulk purchases reduce cost per square meter
• Prices may vary based on market supply conditions

CETECH Ghana offers competitive pricing, transparent quotations, and bulk supply options for contractors, developers, and institutions.

Performance and Moisture Protection Capability

Black polythene and damp proof rubber membranes provide:

• Complete moisture barrier against rising damp
• Protection against ground water vapor
• Reduced risk of mold and mildew
• Improved indoor air quality
• Enhanced durability of concrete slabs

When properly installed, a damp proof membrane can protect a building for decades.

Damp Proof Membrane for Walls

A damp proof membrane for walls is installed to prevent moisture penetration through:

• Foundation walls
• Basement walls
• Retaining walls
• External block walls

In Ghana, wall damp proofing is especially important in:

• Flood-prone areas
• Coastal regions
• Low-lying land developments

CETECH Ghana supplies membranes suitable for vertical and horizontal wall applications.

CETECH Ghana helps customers select the right option based on application and budget.

Advantages Over Tarpaulins and Inferior Materials

Some builders attempt to use tarpaulins or thin nylon sheets as damp proof materials. This approach leads to failure.

Advantages of Proper Damp Proof Membrane

• Guaranteed waterproof performance
• Consistent thickness
• Resistance to puncture
• Long-term durability
• Compliance with construction best practices

Tarpaulins are not designed for permanent ground contact and should not be used as damp proof membranes.

Durability and Lifespan

High-quality black polythene and rubber-based damp proof membranes can last:

• 20–50 years when properly installed
• Longer when protected by concrete and finishes

They are resistant to:

• Soil chemicals
• Bacteria and fungi
• Moisture degradation

This makes them suitable for long-term structural protection in Ghana.

Safety and Compliance Relevance

Damp proof membranes contribute to:

• Structural integrity
• Healthy indoor environments
• Prevention of mold-related health issues
• Compliance with modern building standards

Using proper damp proof material is considered a best practice in professional construction.
