Protect floors, concrete slabs and building structures against rising damp, ground moisture and water ingress with this Extra Heavy Duty 2000 Gauge Damp Proof Membrane (DPM).
Manufactured from extremely robust 500 micron / 2000 gauge polythene, this heavy duty waterproof membrane provides a substantial moisture barrier for use beneath concrete floors, screeds, slabs and other building structures where increased strength and durability are required.
Supplied in a 4m x 12.5m roll, each membrane provides approximately 50m² of coverage before allowing for overlaps, making it an excellent choice for domestic, commercial and trade construction projects.
At 2000 gauge / 500 micron / 0.5mm thick, this is an exceptionally substantial damp proof membrane designed for demanding construction applications.
Its 500 micron construction is twice the thickness of a 250 micron DPM, providing increased durability for projects where a standard or lighter membrane may not provide the required level of robustness.
For customers searching for 2000 gauge DPM, 500 micron damp proof membrane, extra heavy duty DPM or 0.5mm damp proof membrane, this product provides a strong professional-grade solution.
Moisture from the ground can travel upwards through porous construction materials if a suitable barrier is not installed.
A correctly fitted Damp Proof Membrane creates a continuous waterproof layer between the ground and floor construction, helping prevent water and moisture reaching the building above.
This can help reduce the risk of:
One of the main advantages of this membrane is its substantial 500 micron thickness.
For comparison:
2000 Gauge = 500 Micron = approximately 0.5mm
This makes the membrane twice as thick as a standard 1000 gauge / 250 micron DPM.
The increased thickness provides a much more substantial sheet for projects where durability and resistance to accidental damage are particularly important.
Each roll measures 4 metres wide by 12.5 metres long, providing approximately 50 square metres of material before allowing for overlaps and detailing.
The generous 4m width helps reduce the number of individual joints required across many floor areas.
This makes it particularly useful for:
Each roll provides approximately 50m² of membrane before overlaps.
When calculating the quantity required, remember to allow additional material for:
Actual usable coverage will therefore be slightly lower than 50m² depending on the shape and complexity of the project.
This Extra Heavy Duty DPM is BBA Certified, providing additional reassurance for builders, contractors and professional specifiers requiring an independently assessed building membrane.
BBA certification can be particularly important on projects where product performance, specification and compliance need to be clearly documented.
The membrane is also CE marked for appropriate construction applications.
This DPM is specified as CE Certified No. 1454 to EN 14909:2012 Type A.
This provides further reassurance that the membrane has been manufactured and tested for its intended damp-proofing application.
For trade buyers and specifiers searching specifically for a certified damp proof membrane, this is a valuable product feature.
The membrane has a specified watertightness greater than 2kPa, helping provide dependable protection against moisture penetration when installed correctly.
For the DPM to work effectively, it is essential to maintain a continuous waterproof barrier across the complete floor area.
Joints, corners and penetrations should therefore be carefully detailed and sealed.
One of the primary applications for this Extra Heavy Duty DPM is beneath concrete floors and ground-bearing slabs.
The membrane can form an important moisture barrier within floor constructions incorporating:
Correct positioning should always follow the relevant floor specification and building requirements.
The substantial 500 micron construction makes this DPM particularly suitable for projects where a stronger membrane is preferred over lighter standard DPM.
Typical applications include:
The membrane is manufactured from tough polythene, providing a combination of waterproofing, flexibility and durability.
Despite its extra heavy duty thickness, it can still be formed around building details such as:
This allows a continuous moisture barrier to be created across complex floor areas.
One of the main reasons for choosing a 500 micron DPM is the increased material thickness.
Construction sites can expose membranes to:
The extra heavy duty construction provides a more substantial membrane for projects where additional robustness is desirable.
Care should still be taken to avoid puncturing or tearing the membrane during installation.
This DPM is specified as resistant to low temperatures down to approximately -25°C.
This helps the material retain suitable performance during colder storage and construction conditions.
Moisture travelling through an inadequately protected concrete floor can cause problems with finished flooring.
Potentially affected materials can include:
Installing an appropriate damp proof membrane helps protect the complete floor construction against moisture originating from the ground.
Excess moisture can create conditions that encourage mould and fungal growth.
By helping prevent ground moisture entering the floor construction and internal environment, a correctly installed DPM contributes towards keeping building materials drier.
This helps protect both the building structure and subsequent internal finishes.
Correct installation is essential for achieving effective moisture protection.
When installing:
Always follow the relevant project specification and building requirements.
A floor Damp Proof Membrane (DPM) often needs to connect with the building’s Damp Proof Course (DPC).
Correctly linking these two damp-proofing systems helps create a continuous moisture barrier between the floor and surrounding walls.
This is particularly important around floor perimeters and wall junctions where gaps could potentially allow moisture to bypass the membrane.
Although both protect buildings against damp, DPM and DPC are different products.
A Damp Proof Membrane (DPM) is normally supplied as a large sheet and installed beneath floors, concrete slabs and screeds.
A Damp Proof Course (DPC) is typically supplied in narrower rolls and installed within brick or block walls.
Using both correctly can help create a continuous barrier against ground moisture throughout the building.
The extra heavy duty polythene construction can also make this membrane useful for temporary protection during construction.
Potential additional applications can include:
For specialist applications, always confirm that the product is suitable for the intended use.
The combination of 500 micron thickness, BBA certification and 50m² roll size makes this DPM particularly attractive to professional builders and contractors.
It is suitable for:
Choose Extra Heavy Duty Damp Proof Membrane 2000 Gauge / 500 Micron – 4m x 12.5m for a substantial, certified and dependable moisture barrier designed for concrete floors, slabs, extensions, garages and demanding construction projects.
