IGLÙ® BARRIER

This system is the safest way to protect below-ground walls which are intended to last over time and will accompany the structure throughout its service life.‎ When Iglu’® Barrier disposable formworks are connected to a ventilated cavity under the foundation, they create a “chimney effect” which can then increase the outflow of moisture and Radon gas.‎ Installing a ventilated cavity between a waterproofed retaining wall and the backfill eliminates contact between the ground and the waterproofing.‎ Retaining walls and other walls that are in contact with the ground are exposed to damp due to capillary action; added to this is the possibility of damp air resulting from inadequate thermal insulation.‎ This situation can lead to the formation of mould, unpleasant odours and, more importantly, it can compromise the durability of the structure.‎ It is therefore imperative to select materials that maintain their impermeability to water and water vapour as well as their rot-resistance and mechanical strength over time, even when under loads from construction-site vehicular traffic.‎ ADVANTAGES Since the thermal insulation used for the external surface of the wall is subject to extremely high stresses due to its continuous contact with the ground, the associated lithostatic load and the effects of moving loads, as well as contact with rainwater, Iglù® Barrier offers optimal performance with regard to: - ventilation in all directions thanks to the cavity created by laying Iglù® Barrier directly in contact with the - waterproofing membrane; - better environmental conditions in underground rooms; - lower incidence of problems with humidity and moisture; - reducing the “cold wall” effect; - effective “impact protection” for waterproofing during the backfilling phases of the excavations; - forming a root barrier to protect the waterproofing; - reducing installation costs compared to the traditional system using gravel and a dimpled membrane; - easy installation; - ease of storage and handling on site; - suitability for laying under all weather conditions; - benefitting the durability of the building, potentially extending its service life and increasing its value.‎ APPLICATIONS The presence and diffusion of moisture in construction works generates a multitude of problems.‎ Discomfort and damage affect both the contemporary building sector and various areas within the restoration and conservation sectors.‎ Capillary rising damp and infiltration into below-ground structures or into structures used to contain soil are among the principle causes of deterioration in building works.‎ Due to its special configuration and the natural air chamber that forms between the wall and the panel, the Iglù® Barrier panel protects walls in below-ground living spaces (such as cellars, garages, laundries, taverns, etc.‎) from both “penetrating damp” (a.‎k.‎a.‎ lateral damp) and temperature changes.‎ The cost reduction compared to traditional systems, the guarantee of eliminating contact between soil moisture and the waterproofing membrane, the excellent resistance to compression combined with the ease of installation and handling on site, make Iglù® Barrier an essential product for the protection of walls in contact with the ground.‎ Further info from manufacturer on IGLÙ® BARRIER Daliform Group
