Assessment of waterproofing building solutions with synthetic sheets
Waterproofing membranes for flat roofs are regulated by harmonized standards that engage manufacturers with the declaration of performance of the sheets themselves, but without going into how to put them in place correctly or how to meet the requirements of national building regulations such as the Spanish CTE. This assessment document addresses these shortcomings, defining the correct installation of the sheet and its accessory range, and clarifying the degree of compliance with CTE.
Regulatory situation of a range of waterproofing sheets for tunnels
The manufacturer of a range of multilayer composite sheets for waterproofing tunnels has difficulties to clarify if these products can be tested according to the verification methods of European standard EN 13491. ITeC has checked if the composition of the sheet and its working fits totally or partially within the scope of the standard, which is an unavoidable step for elucidating whether the manufacturer can get a CE-mark for their products or not.
Evaluation of liquid waterproofing systems for roofs and bridge decks
Development and analysis of the regulatory and functional requirements to evaluate at European level different products and systems for liquid waterproofing based on polyester, polyurethane or bituminous derivatives, with or without reinforcement meshes. The requirements vary according how much lifespan is expected from the product, the climate zone where it is placed, the degree of weather protection of the membrane, the slope of the roof and the amount of service load that must withstand.
Assessment of a mechanical sealing system for concrete walls
Development of the European assessment protocol 06.05/33 for checking the compliance of a system of elastic fasteners that are used to seal the holes left by the formwork ties in concrete walls. It contemplates the situation where the hole is under water pressure, and exposed to high and low temperatures.
Evaluation of waterproofing systems for concrete structures exposed to water
Definition of requirements for building systems where mortars are used to waterproof concrete structures that have an occasional contact with water (such as retaining walls) or a permanent contact (such as tanks, cannels or pools). It emphasizes the correct application of the different products involved, avoiding discontinuities as much as possible and specifying the correct way to proceed with joints, edges and other vulnerable points.
Mastic asphalt (Gussasphalt) with crumb rubber from end-of-life tires
Experimental test campaign to measure the effects of adding recycled rubber dust to the mix for manufacturing mastic asphalt. Since mastic asphalt is not just a material for building wearing surfaces but is also used in waterproofing applications, special care has been taken to assess how the change in composition affects its reaction to water and water vapour.
Experimental behaviour of sheets for watertightness reinforcement under pitched roofs
Analysis of the behaviour of the sheets as a part of a constructive solution for building pitched, tiled roofs over a concrete base. It has tested the influence on the drying process of the concrete base, the risk of condensation on the sheet and the contribution of the sheet in the water tightness of the roof as a whole.
