150mm Wide Damp Proof Course
A correctly installed Damp Proof Course is an important part of protecting buildings against moisture rising from the ground.
Installed horizontally within masonry, the DPC creates a waterproof barrier designed to interrupt the upward movement of moisture through porous building materials.
For customers searching for 150mm damp proof course, 30m DPC roll, DPC for brickwork, or wall damp proof membrane, this six-roll pack provides a practical solution for domestic, commercial and trade construction projects.

Helps Prevent Rising Damp
Rising damp occurs when moisture from the ground travels upwards through porous construction materials such as brickwork, blockwork and mortar.
Without a suitable damp-proof barrier, moisture can eventually reach internal walls and finishes, potentially causing damp patches and deterioration.
Installing a suitable DPC within the masonry helps interrupt this upward movement of moisture.
A correctly installed damp proof course can help reduce the risk of:
- Rising damp
- Damp patches on walls
- Moisture penetration
- Mould growth
- Mildew
- Fungal residues
- Damaged plaster
- Peeling paint or wallpaper
- Moisture-related deterioration of masonry
Practical 150mm Width
At 150mm wide, this DPC is suitable for many common brick and block wall applications.
The manageable width makes it straightforward to handle and position during construction while providing sufficient coverage for a wide range of standard masonry details.
Typical applications include:
- Brick walls
- Block walls
- Cavity wall details
- Internal masonry
- External masonry
- Wall junctions
- Extensions
- Garages
- General building work
Pack of 6 x 30m Rolls
Each pack contains 6 individual rolls, with every roll measuring 150mm wide x 30m long.
That provides a total of 180 linear metres of damp proof course per pack.
The six-roll pack is particularly useful for:
- New-build projects
- House extensions
- Garages
- Workshops
- Long wall runs
- Multiple walls
- Property renovation
- Trade construction work
Having several rolls available also provides useful extra material for overlaps, corners and detailed areas.
Serrated Diamond-Cut Surface
This damp proof course features a serrated diamond-cut texture on both the upper and lower surfaces.
The textured finish is designed to improve grip within the mortar bed and help prevent the DPC from slipping while bricks or blocks are being positioned.
Benefits include:
- Improved mortar grip
- Better installation stability
- Reduced membrane movement
- Easier brick and block positioning
- More secure placement within masonry
This makes the DPC particularly practical for permanent installation within brick and block construction.
Suitable for Brick & Block Walls
This DPC is designed for horizontal anti-damp isolation within brick and block masonry.
It can be incorporated into a wide variety of wall constructions to help create a continuous moisture barrier.
Typical applications include:
- Brick walls
- Concrete block walls
- Cavity walls
- External walls
- Internal masonry walls
- House extensions
- Garages
- Workshops
- Garden buildings
- New-build properties
- Refurbishment projects
Durable & Flexible Construction
A damp proof course needs to provide dependable long-term protection while remaining flexible enough for straightforward installation.
This 150mm DPC combines both qualities.
Its flexible construction makes it easy to:
- Roll out
- Position
- Cut
- Form around corners
- Fit around wall junctions
- Adapt to different masonry details
while maintaining the durability required for permanent use within walls.
Alkali Resistant
Mortar and other cement-based building materials are naturally alkaline.
Because DPC remains permanently incorporated within masonry, resistance to alkaline conditions is important for long-term durability.
This damp proof course is alkali resistant, helping it remain suitable for prolonged contact with mortar, brickwork and blockwork.
Watertight at Greater Than 2kPa
The DPC has a specified watertightness greater than 2kPa, helping it provide an effective barrier against moisture when correctly installed.
Maintaining a continuous DPC is essential.
Particular care should be taken around:
- Corners
- Wall junctions
- Door openings
- Window openings
- Changes in level
- Service penetrations
- Overlapping sections
to avoid gaps where moisture could bypass the damp-proof barrier.
Low-Temperature Resistance to -25°C
This damp proof course is designed to remain resistant at temperatures down to approximately -25°C.
This helps maintain flexibility during colder storage and construction conditions.
Ideal For
The 150mm Wide Damp Proof Course is suitable for a wide variety of construction projects, including:
- New-build houses
- House extensions
- Garages
- Workshops
- Garden rooms
- Outbuildings
- Brick construction
- Block construction
- Cavity wall details
- Property refurbishment
- Masonry repairs
- General building projects
DPC Installation
Correct installation is essential for creating an effective moisture barrier.
When installing:
- Ensure the mortar bed is level and properly prepared
- Lay the DPC flat without unnecessary folds or creases
- Make sure the membrane covers the required wall width
- Maintain continuity around corners and junctions
- Allow suitable overlaps where separate lengths meet
- Avoid puncturing or damaging the membrane
- Bed the DPC securely into the mortar
- Connect adjoining damp-proofing systems correctly where required
- Follow the project specification and applicable building requirements
A continuous DPC is important because breaks or damaged sections may allow moisture to bypass the barrier.
DPC vs DPM – What’s the Difference?
A Damp Proof Course (DPC) and Damp Proof Membrane (DPM) both protect buildings against moisture, but they are normally used in different areas.
A DPC is generally installed horizontally within walls to prevent moisture travelling upwards through brickwork and blockwork.
A DPM is usually supplied as a much wider sheet and installed beneath concrete floors and slabs.
In many construction projects, the two systems are connected to create a continuous damp-proof barrier throughout the building.
Connect the DPC to the Floor DPM
Where a building also incorporates a floor Damp Proof Membrane, the wall DPC and floor DPM may need to be correctly connected.
Maintaining continuity between both systems helps reduce the risk of moisture finding an alternative route into the building.
Always follow the relevant construction detail and project specification when linking DPC and DPM products.
Suitable for New Builds & Refurbishment
The 150mm Wide DPC is suitable for both new construction and appropriate refurbishment work.
It is particularly useful when:
- Constructing new brick or block walls
- Building an extension
- Constructing a garage
- Completing cavity wall details
- Rebuilding damaged masonry
- Improving existing damp-proofing
- Carrying out general property renovation
