Bituminous Membrane Waterproofing in Malta
The bituminous membrane is our flagship product and the most trusted roof waterproofing system in Malta. Also known as a torch-welded or "carpet" membrane, it is heat-welded directly onto the surface to form a tough, seamless barrier that keeps water out for decades. It's the ideal solution for flat roofs, terraces and appoggi on both residential and commercial buildings.
At WP Ltd we've been installing bituminous membranes across Malta and Gozo since 1988.
Every roll we apply is BBA, ITC or ISO certified, and every installation is backed by a guarantee of up to 20 years — so you get lasting protection against leaks, damp and water infiltration.
Why choose a Bituminous Membrane?
- Extremely durable — a lifespan of 20–30 years when correctly installed
- Seamless, fully-bonded finish with no weak joints for water to penetrate
- Withstands Malta's intense summer heat, UV and winter storms
- Suitable for flat roofs, terraces, appoggi, gutters and foundation walls
- Certified materials and a guarantee of up to 20 years
- Choice of colours including red, white, grey, green, and dark grey, along with black, which is often used for walls or basements.
- Various thicknesses 4kg, 4.5kg, 4mm, and 5mm
Types of Bituminous Membrane
- APP-modified Bitumen
This asphalt-like material, enhanced with minuscule granules and particles, offers superior protection by effectively deflecting the sun’s UV rays, making it highly resistant to weathering and solar damage.
- SBS-modified Bitumen
This smooth, elastic asphalt membrane is perfect for use on foundation walls, interior walls, and concrete screed roofs, offering excellent flexibility and durability in various applications.
Applications of Bituminous Membrane
Perfect for flat and low-pitch roofs, accessible terraces, appoggi, parapet walls and below-ground foundations. Whether you're building new or fixing a leaking roof, our team prepares the surface, torches on the membrane and finishes it to last.

Liquid Membrane Waterproofing in Malta
A liquid membrane is a cold-applied, seamless waterproofing coating that's brushed or rolled onto the surface and cures into a flexible, watertight skin. Because it has no joints or seams, it's the perfect choice for balconies, terraces, penthouses and the awkward, detailed surfaces where a sheet membrane simply can't reach.
WP Ltd applies premium, certified liquid membrane systems across Malta and Gozo for both homes and commercial properties. The result is complete, gap-free protection that moulds around pipes, corners, upstands and drains — sealing out water wherever leaks tend to start.
Why choose a liquid membrane?
- Fully seamless — no joints, overlaps or weak points
- Flexible finish that bridges hairline cracks and movement
- Ideal for balconies, terraces, penthouses, front gardens, porches, wet rooms and complex shapes
- Bonds tightly to concrete, screed, tiles and existing membranes
- UV-stable options that stand up to Malta's climate
Types of Liquid Membrane
Polyurethane (PU) Liquid Membrane
This high-performance, cold-applied membrane cures into a tough, highly elastic film that bridges cracks and withstands foot traffic — making it ideal for exposed balconies, terraces and roof decks that need lasting, flexible waterproofing.Acrylic Liquid Membrane
A water-based, UV-stable coating that reflects heat and resists weathering. Its excellent adhesion and breathability make it well suited to roofs and terraces exposed to Malta's intense summer sun.Cementitious Liquid Membrane
A rigid, cement-based coating that bonds tightly to concrete and masonry. Perfect for water tanks, wells, basements, planters and other below-ground or constantly wet surfaces.Bituminous Liquid Membrane
A cold-applied, bitumen-based coating that forms a seamless, flexible barrier. Ideal for foundation walls, hidden gutters and awkward details where a torch-on membrane isn't practical.
Applications of Liquid Membrane
The go-to solution for leaking balconies and terraces, penthouse decks, planters and roof gardens, shower bases, and any surface with heavy detailing. We diagnose the source of the leak, prepare the surface and apply the right system to stop it for good.

Roof & Wall Insulation in Malta
Insulation keeps your building comfortable and your energy bills down. Our insulation membranes regulate indoor temperature in homes and commercial properties across Malta, keeping interiors cooler through the hot summer months and warmer during damp winters. Paired with waterproofing, insulation protects the structure while improving everyday comfort.
WP Ltd supplies and installs certified thermal insulation systems for roofs and walls throughout Malta and Gozo. Better insulation means less heat gain in summer, less heat loss in winter, and a noticeable drop in air-conditioning and heating costs.
Why insulate with WP Ltd?
- Lower cooling and heating bills through improved energy efficiency
- A more comfortable, stable indoor temperature all year round
- Reduces condensation, damp and mould risk
- Can be combined with our waterproofing systems in a single project
- Certified materials installed by an experienced local team
Types of Insulation
Thermal Insulation Boards
Rigid boards — such as XPS and EPS — laid beneath the waterproofing to block heat transfer through the roof. Ideal for flat roofs and terraces, they keep interiors cooler in summer and warmer in winter while adding a protective layer over the structure.Polyurethane (PU) Spray Foam Insulation
A seamless spray-applied foam that expands to fill every gap, delivering excellent thermal performance and a degree of waterproofing in one application. Perfect for irregular roofs and hard-to-reach areas where boards can't sit flush.Reflective / Thermal Membrane Insulation
A lightweight membrane that reflects the sun's heat away from the building, reducing surface temperature and heat gain. Well suited to Malta's intense summer sun and often combined with a waterproofing layer.Acoustic & Cavity Insulation
Insulation fitted within walls and cavities to regulate indoor temperature and reduce noise. Ideal for commercial buildings and homes seeking better energy efficiency and year-round comfort.
Applications of Insulation
Suits flat roofs, terraces and external walls on both new builds and existing buildings. We'll recommend the right thermal system for your property and, where needed, integrate it with a bituminous or liquid membrane for complete protection.
