External Waterproofing
For outdoor projects that demand total waterproofing protection, MPS has the solution. We can handle the manufacture and delivery of the right system, giving you the added peace of mind that comes with up to 30-year warranties.
Hot melt system
Get the durability of asphalt with the assurance of a fully bonded system’s elastic, self-healing properties. Our monolithic roofing system is our most popular product of its type and BBA-approved.
The membrane is made from blended polymer-modified bitumen, natural rubber, and ultra-light fillers. Reinforced with high tensile heat-resistant polyester fabric, it provides exceptional strength, flexibility, and adhesion.
The inverted system puts insulation above the waterproofing layer, covered by stones, paving, or a living roof. That means total protection and hands-on practicality for your project.
Cold-applied liquid waterproofing
Give your above-ground project the flexibility and durability of our seamless cold-applied system. Ideal for green roofs, podium decks, swimming pools, suspended slabs, terraces, and balconies.
Whether you’re working on a refurbishment or new build, you’ll feel all the benefits of hybrid polymer waterproofing technology:
- BBA approved
- Easy to apply and quick drying
- Durable and weather resistant
- Perfect for projects of any size
Cold-applied liquid Overlay
For degraded single-ply membranes, we’ve got a rubber-based top and base coat that offers outstanding protection. Using synthetic resins and fast-drying solvents, you can add serious life expectancy to older builds, with benefits like:
- Simple, fast application in only two to four hours
- Air curing for application at low temperatures
- A closer substrate bond thanks to nanotechnology
- Self-sufficiency, with no need for added solar protection
MPS gives you peace of mind, rain or shine
