Polyethylene Damp Proof Course Market Report 2026

The polyethylene damp proof course market size has grown strongly in recent years. It will grow from $1.2 billion in 2025 to $1.28 billion in 2026 at a compound annual growth rate (CAGR) of 6.5%. The growth in the historic period can be attributed to housing construction growth, damp prevention standards, availability of polyethylene films, urban expansion, building code enforcement.

The polyethylene damp proof course market size is expected to see strong growth in the next few years. It will grow to $1.63 billion in 2030 at a compound annual growth rate (CAGR) of 6.2%. The growth in the forecast period can be attributed to green building initiatives, infrastructure investments, use of recycled plastics, rising awareness of moisture control, modernization of construction materials. Major trends in the forecast period include rising demand for moisture protection materials, expansion of residential construction, growing use of recycled polyethylene sheets, increased adoption in infrastructure projects, focus on long term building durability.

The rise in construction activities is expected to drive the growth of the polyethylene damp proof course market in the coming years. Construction activities encompass the building, repairing, or modification of structures such as buildings, roads, bridges, and other infrastructure. This increase in construction is largely attributed to urbanization, as growing populations in urban areas heighten the demand for residential, commercial, and infrastructure development. Polyethylene damp proof courses support these projects by serving as flexible, easy-to-install barriers against rising damp. They contribute to structural durability and are suitable for a wide range of construction applications. For example, in April 2025, the United States Census Bureau reported that construction spending reached $2.19 trillion in 2024, up from $2.07 trillion in 2023. As a result, the expansion in construction activities is fueling the growth of the polyethylene damp-proof course market.

The increase in home renovations is expected to contribute to the growth of the polyethylene damp proof course market. Home renovation involves upgrading, improving, or restoring residential properties to enhance their functionality, aesthetics, and value. This trend is driven by an aging housing stock, as many older homes require repairs, energy efficiency improvements, and modernized layouts, encouraging homeowners to renovate rather than relocate or rebuild. Polyethylene damp proof courses play a vital role in home renovations by acting as effective moisture barriers, making them particularly suitable for retrofitting older buildings. They help mitigate rising damp, thereby improving structural soundness and ensuring long-term durability in residential structures. For instance, in June 2024, Statistics Finland reported that homeowners spent €5.2 billion ($5.63 billion) on renovating dwellings and residential buildings in 2023, a 2.7% increase from 2022. Consequently, the rise in home renovations is driving demand in the polyethylene damp proof course market.

The growing need for infrastructure development is projected to boost the polyethylene damp proof course market. Infrastructure development involves the design, construction, and maintenance of critical physical systems such as transportation, energy, water, and communication networks. This growth is fueled by urbanization and economic development, which create a rising demand for upgraded public utilities, transport systems, and energy infrastructure. Polyethylene damp proof courses contribute to these large-scale developments by delivering durable moisture protection, thereby improving structural integrity and extending the lifespan of infrastructure projects. For instance, in July 2024, the Office for National Statistics reported that total general government investment in infrastructure reached $17.25 billion (£13.8 billion) in 2023, a 3.9% increase from 2022. Therefore, the escalating demand for infrastructure development is propelling the polyethylene damp proof course market forward.
