TL;DR: 2000g polythene sheeting is the thickest and most durable damp proof membrane available for construction use. Supplied by Indigo Supplies in 4m x 25m rolls in blue or black, it offers maximum protection against moisture ingress in demanding environments. Indigo Supplies also stocks 1200g and 1000g options, plus a full range of specialist polythene sheeting products.
If you work in construction, you already know that cutting corners on damp proofing is a decision that tends to come back and haunt you—usually through a wall. Getting the right damp proof membrane for the job isn't just good practice, it's essential. And when it comes to sheer toughness, nothing in our range beats the 2000g DPM.
At Indigo Supplies, we've been supplying industrial materials to trade professionals since 1998. We know what construction sites demand—reliability, strength, and products that do exactly what they say on the tin. Our ultra heavy duty 2000g polythene sheeting is built for that reality. Whether you're laying floors, lining trenches, or wrapping foundations, this is the membrane that won't let you down.
This post covers everything you need to know about our 2000g damp proof membrane, how it compares to lighter grades, and why Indigo Supplies is the supplier of choice for construction teams across the UK.
What Is a 2000g Damp Proof Membrane—and Why Does Thickness Matter?
A damp proof membrane (commonly referred to as a DPM) is a layer of polythene sheeting placed beneath concrete slabs, along walls, or across ground floors to prevent moisture rising from the ground into a structure. The "g" measurement—1000g, 1200g, 2000g—refers to the weight of the film per 1,000 square metres, which is a direct indicator of thickness and durability.
Put simply: the higher the number, the tougher the membrane. A 2000g damp proof membrane is the heaviest duty option on the market for standard construction applications. It's significantly more resistant to tearing, puncturing, and wear during installation than thinner grades—making it the preferred choice for high-specification builds, commercial projects, and groundworks where the sub-base is rough or uneven.
Our Ultra Heavy Duty 2000g Polythene Sheeting: The Specs
Our 2000g polythene is the flagship product in our DPM range—and with good reason. Here's what you get:
- Size: 4m x 12.5m per roll
- Thickness: 2000g (ultra heavy duty)
- Colours: Available in blue polythene or black polythene
- Application: Ground floor slabs, foundations, below-slab installation, commercial and residential construction
- Durability: Puncture and tear-resistant, designed to withstand the rigours of a live construction site
Whether you prefer blue or black, both options deliver identical performance. The colour choice is typically a matter of site preference or project specification. Blue is traditionally associated with DPM products and is easy to identify on site, while black offers a discreet finish and is widely used across general groundworks.
How Does 2000g Compare to 1200g and 1000g DPM?
Not every job calls for the same level of protection. That's why we stock three grades of damp proof membrane, so you can match the product to the project:
1000g Polythene — Heavy Duty DPM
Our entry-level DPM grade. The 1000g DPM is suitable for lighter-duty applications where the sub-base is well-prepared and the risk of puncture during installation is lower. Available in blue and black, this is a cost-effective option for straightforward residential builds.
1200g Polythene — Super Heavy Duty DPM
Step up to the 1200g damp proof membrane for projects requiring greater resistance. The 1200g DPM handles rougher sub-bases and is a popular choice across a wide range of commercial and domestic construction projects. Again, available in blue and black.
2000g Polythene — Ultra Heavy Duty DPM
The 2000g damp proof membrane is the one you reach for when there's no room for compromise. Thicker, tougher, and far more resistant to on-site damage—this is the grade specified on high-performance projects, or anywhere the groundwork conditions make puncture a genuine risk. If you're working on a demanding site and you only want to lay the membrane once, this is the one.
Choosing between grades? Opt for 1000g polythene if budget is the primary concern and conditions are ideal. Choose 1200g polythene if you need a reliable all-rounder for most commercial builds. Go for 2000g polythene when the specification demands maximum performance or site conditions are rough.

What Makes 2000g Polythene Sheeting the Right Choice for Demanding Construction Sites?
On a busy construction site, things happen. Sub-base materials aren't always clean. Workers walk across membranes before concrete is poured. Equipment gets dragged. A thinner DPM that gets punctured during installation isn't a DPM at all—it's just an expensive inconvenience.
The 2000g damp proof membrane is engineered to absorb the kind of punishment that sites dish out without compromising performance. That means:
- Greater puncture resistance during laying across rough or stony sub-bases
- Superior tear strength when manoeuvring large sheets into position
- Reliable moisture barrier performance once installed, protecting the structure for its lifetime
- Peace of mind that the job has been done to the highest standard
For commercial projects, high-specification residential builds, or any application where the spec calls for maximum protection, the 2000g DPM from Indigo Supplies is the straightforward answer.

Frequently Asked Questions
What is 2000g polythene sheeting used for in construction?
2000g polythene sheeting is used as a damp proof membrane (DPM) in construction. It is laid beneath concrete floor slabs, along foundations, and across ground floors to prevent moisture rising from the ground into a building. The 2000g grade is the heaviest duty standard DPM available, offering maximum resistance to puncture and tearing during installation on rough or demanding sub-bases.
What is the difference between 1000g, 1200g and 2000g damp proof membrane?
The key difference is thickness and durability. 1000g DPM is a heavy duty option suited to well-prepared sub-bases and lighter-duty applications. 1200g DPM offers greater puncture resistance and suits a wider range of commercial and residential projects. 2000g DPM is the ultra heavy duty grade, specified where conditions are particularly demanding or where maximum performance is required.
