Internal Membrane Systems

Advanced Internal Membrane System Installation

At Eco Damp Solutions, we specialise in internal membrane systems — advanced waterproofing solutions designed to protect basements and below-ground spaces from moisture ingress. Our internal membrane systems consist of high-density polyethylene (HDPE) or similar waterproof membranes applied to internal walls and floors.

We create effective barriers that prevent water and moisture from penetrating your living space. Our internal membrane systems work in conjunction with drainage channels and sump pumps to manage water accumulation, providing reliable protection even in areas with high water tables or where external waterproofing isn't feasible. For properties considering a full basement conversion, an internal membrane system is often the essential first step.

Our experienced installers serve properties throughout Basingstoke, Southampton, Portsmouth, Bournemouth, and across the UK, delivering professional internal membrane solutions with minimal disruption.

Key Features

Highly Effective Waterproofing

Our internal membrane systems provide a highly reliable waterproofing solution, managing water ingress at the wall and floor level to keep your basement or lower ground floor completely dry.

Installed Without External Excavation

Unlike traditional tanking methods, internal membrane systems are installed entirely from within the property, removing the need for costly and disruptive external excavation works around your foundations.

Compatible With Various Wall & Floors

Our membrane systems are suitable for use across a wide range of wall and floor constructions, including brick, stone, block, and concrete, making them an adaptable solution for both old and new properties.

Can Include Integrated Drainage Systems

Where required, our internal membrane installations can be combined with an integrated drainage channel and sump pump system, ensuring any water that does enter is efficiently managed and removed from the structure.

Create Additional Living Space

By effectively waterproofing your basement or cellar, an internal membrane system transforms previously unusable damp space into a dry, habitable area that can be converted into a home office, gym, bedroom, or living room.

Long-lasting Protection Against Water

Manufactured from durable, high-density materials, our internal membrane systems are built to last, providing decades of reliable protection against water ingress and backed by our guarantee of up to 25 years.
