SOPREMA's Alsan liquid resins have been developed as high-performance waterproofing and surfacing systems for new build and refurbishment projects. Thanks to their superior elasticity and resistance, these liquid resins envelop a building like a protective, flexible skin. Alsan systems will brave the elements, whether they are exposed to frost, heat or intense solar radiation, delivering durable waterproofing solutions for every structural component.

When it comes to complex details, such as interfaces, upstands and borders on windows and doors, pipe penetrations, stairs, domelights and corners, these flexible synthetic resins are at their most impressive. Thanks to their liquid consistency, they can be used to waterproof any details and shapes with ease.

High-performance waterproofing and surfacing systems for new build
And refurbishment projects

Hard-wearing, complete systems that bond with the substrate to ensure resistance against subsurface migration are designed for waterproofing main roof areas exposed to chemical and biological influences. The surface can be provided with a skid-resistant finish that can also mark out the maintenance paths. These systems are also ideal for modern green roofs.

Roofing

Areas subjected to foot traffic, such as balconies, terraces, access galleries and stairs, require protective surfacing and waterproofing systems that provide superior safety underfoot. Such systems must also be water-impermeable, seamless, and offer high UV-resistance. When a building needs to be refurbished, complete waterproofing and surfacing systems can be installed within a very short time. PMMA and PAS systems in particular are remarkable for their fast cure time, even at very low temperatures, which means that work can be completed rapidly.

Individual designs for all interior
and exterior requirements

A wide range of colours (according to the RAL system) and special effects offer scope for individual designs. Pigmented quartz sands and chipping mixtures in various colours, decorative marble granules and granules providing footfall sound insulation can be used to realise a wealth of creative finishes.

Surface Solutions

Areas subjected to a high volume of rolling traffic, such as in multi-storey and underground car parks, specifically require abrasion-resistant, as well as oil- and fuel-resistant systems. Quartz sand can be broadcast over ramps, exposed decks and internal decks for superior skid resistance. Since the systems can be installed rapidly and also offer a long service life, clients benefit from closures being kept to a minimum and from long-term economic advantages. For road and bridge maintenance the key features again include the long lifespan of these systems, as well as their resistance to frost and de-icing salts. Bridge deck waterproofing using polymer-modified bitumen membranes or spray-applied liquid-resin waterproofing can be applied as part of a system when primed with a bridge deck sealer to create an extremely efficient waterproofing layer under mastic and rolled asphalt surfacing.

Hard-wearing, complete systems
with fast cure time

The wide range of Alsan systems offers surfacing suitable for all interior and exterior requirements. The solvent-free, skid-resistant and hygienic solutions can be applied in public buildings, such as schools, hospitals and administrative buildings. Finishes offering protection against aggressive substances and mechanical stresses are suitable for use in agriculture and food industries.

Flooring

Alsan synthetic resins based on polymethyl methacrylate (PMMA), polyurethane (PU), bitumen-polyurethane (BITU-PU), epoxy (EP) and polyaspartic (PAS) demonstrate a wealth of individual properties and can therefore be used in many different areas. SOPREMA offers the optimum solution for every application.
