Damp Proof Membrane (DPM) solutions for floors and structures

Protection against ground moisture for flooring slabs and structural elements

Effective ground moisture control is essential to protect floor slabs and structural components. Damp Proof Membranes help limit the passage of moisture from the ground into the building fabric, reducing the risk of damage to finishes, insulation and internal environments.

IKO Hyload Damp Proof Membrane systems are flexible polythene and polyethylene sheet materials designed for use above or below ground-bearing concrete slabs and other substrate materials. Used across housing, commercial and public sector developments, they form part of a coordinated moisture control strategy within the building envelope.

With established third-party certification and use in UK construction, the IKO Hyload range provides dependable performance where ground moisture protection is required. IKO Hyload DPM systems are commonly specified alongside Damp Proof Courses (DPCs) to provide continuous protection across floors and walls.

When specified and installed via technical guidance, they support effective, long-term moisture management within the structure. Certain grades within the IKO Hyload DPM range can be specified as part of a ground gas protection system, subject to project-specific design and detailing.

Why use a Damp Proof Membrane for floors and structures?

Ground moisture can affect concrete slabs, floor finishes and internal environments if not properly managed. Damp Proof Membranes help control this risk as part of a specified and designed floor construction.

What a DPM does:

  • Limits the passage of ground moisture through floor slabs.
  • Helps protect internal finishes and floor coverings from moisture-related deterioration.
  • Supports compliance with Approved Document C requirements for resistance to moisture from the ground.

Why this matters for your project

DPMs help reduce the risk of moisture movement affecting slabs, walls and floor finishes when incorporated into a compliant design and installed in accordance with technical guidance.
Managing ground moisture within the building fabric can help reduce the risk of damp patches and mould associated with persistent moisture.
By limiting moisture transmission from the ground, DPM systems support the durability of structural elements and floor coverings over time.

IKO provides technical guidance on the selection and installation of Damp Proof Membranes, Damp Proof Courses and Tanking Membranes as part of a coordinated waterproofing strategy.
