Help protect brickwork, blockwork and masonry against rising damp and ground moisture with this 225mm Wide Damp Proof Course (DPC), supplied as a convenient pack of 4 x 30 metre rolls.
Designed for installation within brick and block walls, this durable and flexible waterproof DPC creates a continuous moisture barrier that helps prevent ground moisture travelling upwards through porous masonry materials.
With a versatile 225mm width, this damp proof course is ideal for a wide range of cavity walls, masonry construction, extensions, garages and general building projects where dependable protection against rising damp is required.
A correctly installed Damp Proof Course is an important part of protecting buildings against moisture rising from the ground.
Installed horizontally within brickwork or blockwork, the DPC creates a waterproof barrier designed to interrupt the upward movement of moisture through bricks, blocks and mortar.
For customers searching for 225mm damp proof course, 30m DPC roll, DPC for brick walls, or damp proof course for cavity walls, this convenient four-roll pack provides a practical solution for domestic and trade construction projects.
Rising damp occurs when moisture from the ground travels upwards through porous building materials such as brickwork, blockwork and mortar.
Without an effective damp-proof barrier, this moisture can eventually reach internal walls and finishes, potentially leading to damp patches and long-term 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:
At 225mm wide, this DPC is a popular and versatile size suitable for a wide range of masonry details.
It provides greater coverage than narrower 100mm and 150mm DPC rolls while remaining straightforward to handle, position and cut during installation.
Typical applications include:
The roll can also be cut where required to suit specific construction details.
Each pack contains 4 individual rolls, with each roll measuring 225mm wide x 30m long.
The four-roll pack is particularly useful for:
Having multiple rolls available also provides useful additional material for overlaps, corners, junctions and other detailed areas.
This Damp Proof Course features a serrated diamond-cut surface on both the top and bottom.
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 of the textured surface include:
This makes it particularly well suited to permanent installation within brick and block construction.
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 barrier against rising moisture.
Typical applications include:
A good damp proof course needs to be durable enough for permanent installation while remaining flexible enough to handle easily during construction.
This DPC combines both qualities.
Its flexible construction makes it straightforward to:
while maintaining the durability required for long-term moisture protection.
Mortar, concrete and other cement-based building materials are naturally alkaline.
Because Damp Proof Course remains permanently incorporated within masonry, resistance to these alkaline conditions is important for long-term performance.
This DPC is alkali resistant, making it suitable for prolonged contact with mortar, brickwork and blockwork.
The DPC has a specified watertightness greater than 2kPa, helping it provide an effective moisture barrier when correctly installed.
Maintaining continuity is essential for effective damp protection.
Particular care should be taken around:
to avoid leaving gaps that could allow moisture to bypass the damp-proof barrier.
This damp proof course is designed to remain resistant at temperatures down to approximately -25°C.
This helps maintain flexibility during colder storage and building-site conditions.
The 225mm Wide Damp Proof Course is suitable for a wide variety of construction projects, including:
Correct installation is essential for creating an effective moisture barrier.
When installing:
A continuous DPC is important because gaps or damaged sections may allow moisture to bypass the barrier.
A Damp Proof Course (DPC) and Damp Proof Membrane (DPM) both protect buildings against moisture, but they are generally installed in different areas.
A DPC is usually installed horizontally within walls to prevent moisture travelling upwards through brickwork and blockwork.
A DPM is generally 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.
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 the two damp-proofing systems helps reduce the risk of moisture finding an alternative route into the building.
Always follow the relevant construction detail and project specification when connecting DPC and DPM products.
The 225mm Wide DPC is suitable for both new construction and appropriate refurbishment work.
It is particularly useful when:
Choose Damp Proof Course 225mm Wide x 30m – Pack of 4 Rolls for a durable, flexible and reliable waterproof barrier designed to help protect brickwork, blockwork and masonry against rising damp and ground moisture.
