Systems

Due to the specific properties of liquid resins – such as low-temperature flexibility, high tear resistance, elasticity, UV-resistance and root-resistance – these materials guarantee reliable waterproofing and surfacing in the construction industry. Every segment and every application has different requirements regarding the liquid-resin system. The different options for system build-ups and materials selected are adapted to the individual requirements associated with a waterproofing or surfacing project. The layers are always fully bonded to the substrate. Consequently such systems, if properly applied and if the stipulated basic conditions are complied with, are absolutely watertight, resistant to subsurface migration and durable. A fundamental requirement for such a waterproofing result is correct substrate preparation and pre-treatment.

ALSAN systems are divided into the four categories of EASY, MEDIUM, LARGE and SUPER Systems: Simply protect. SOPREMA’s EASY-Systems are used in the roofing segment as markings for maintenance paths and escape routes, as facelifts for surfaces showing signs of ageing and as protective layers. In the areas of car parks, flooring and balcony they offer cost-effective solutions and, as simple surface protection systems, prevent the penetration of polluted water. Semi-flexible systems in the car park segment, regenerating and waterproofing the 5th facade. The MEDIUM-Systems are specially designed for applications with more demanding requirements. With their greater thickness and loadability, as well as enhanced crack-bridging properties and approval for use on roof areas, these systems meet every demand.

Versatile, a vast creative spectrum, able to withstand heavy mechanical loads and with high crack-bridging properties: the LARGE-Systems feature a crack-bridging layer, combined with a wearing layer that can withstand mechanical loads and specially formulated finishes. In conjunction with various finishing layers, all aesthetic demands can be met while retaining full technical performance. Everything is possible: the SUPER-Systems stand out due to their customised properties so that they can meet special challenges on site. Whether damp substrates, the need to install thermal insulation underneath the surfacing or install a waterproofing layer underneath asphalt - special supplementary products and innovations from SOPREMA will create individual and solution-oriented systems with absolute added value.
