“…Quantifying penetration of driving rain shows the possibility of substantial leakage for the studied exposed facade. This complies with studies indicating leakage into precast concrete structures due to the fact of driving rain [1,[20][21][22] for the traditional solution and [3,4] for the pre-compressed joint sealing tape. As there are few studies of pre-compressed joint sealing tapes in joints between precast concrete facades, the solution was compared to the traditional solution as a starting point.…”

“…Data available to the design-build contractor are mainly a few essential characteristics of the product as defined in the applicable European Assessment Document [2], which possibly does not contain sufficient information for a risk assessment of the full technical solution applied in a building from a design-build contractor's perspective. Few studies on performance were found, only [3] and [4] specifically addressed the watertightness of joint sealing tapes in precast concrete sandwich panels. Instead, reference cases are referred to by suppliers to verify performance, but these often lack adequate assessment and documentation leaving the design-build contractor with an incomplete basis for decision making.…”

Risk Assessment of Joint Sealing Tape in Joints between Precast Concrete Sandwich Panels Resilient to Climate Change

Lately, a new technical solution, pre-compressed joint sealing tapes in precast concrete sandwich panel facades, has been introduced in Sweden. Although the consequences of performance failure can go far beyond the component, affecting the building, the introduction has gained little attention in terms of risk assessment in the literature and in industry. Instead, reference cases are used as verification without formal evaluation, potentially leading to serial failure. The aim of this paper was to provide guidance on how a design–build contractor should handle this new technical solution. A risk assessment framework using a design–build contractor’s perspective was applied to the case. The framework addresses new technical solutions or adaption to new conditions (e.g., climate change) with the aim of preventing serial failures. Moisture conditions within the joints were simulated using present and future climates, and probabilities of failure were assessed using the Monte Carlo method. The results of the study included identified risks of failure associated with the solution and factors influencing the probability of failure. A main issue was the exposure of the facade to driving rain but also run-off areas and imperfections in the application of the joint sealing tape. Future climate changes affect performance negatively. In conclusion, the new technical solution might be possible to use if draining potential is ensured in all detailed designs and a set of recommendations, including full-scale testing, is provided for the design–build contractor.

“…Research [1] showed that after 8 months of outdoor aging, some of the exterior air barrier tapes, glued to the outer wall of the barrack hut from plywood panels, completely or largely peeled off from the glued surface, while others showed a change in color, bubbling, or other signs of degradation. A maintaining/losing the sealing purpose of self-adhesive tapes, as well as finding promising solutions to ensure the airtightness of the building are investigated mostly [2][3][4][5][6][7][8][9][10]. However, very few studies aim to investigate the aging of tapes and the factors influencing the deterioration of tapes' properties.…”

The use of sealing tapes in creating a continuous envelope to ensure the airtightness of the building is an essential factor. The study aims to investigate the performance properties of single-sided self-adhesive tapes for building applications and to obtain the changes in these properties due to the effects of environmental factors. The tapes were glued to the different substrates. Peel adhesion, tack of the tapes, and the air permeability of sealed elements were determined. The adhesive tape were aged in the laboratory using two different methods, standard (EN 12024) and a new one, during which the test samples were exposed to the cyclic impact of the temperature and humidity of multiple levels. Analysis of the results showed that the substrate has influence on the adhesive behaviour of the self-adhesive tapes. After artificial aging, in most cases, the performance properties of the tapes do not change significantly. The novel approach allowed the comparison of the influence of different aging factors on the change in the performance properties of the tape and contributed to the development of a methodology for testing the durability of sealing tapes. The effect of substrate on tape adhesion was also investigated, which is useful from both a practical and a methodological point of view.

“…However, the number of studies that could be found addressing the watertightness performance of these foam sealing tapes is limited. Svensson Tengberg et al and Olsson [16,20], Farrington et al [17], and Van Linden and Van Den Bossche [21] reported results of laboratory and field tests assessing the watertightness of foam sealing tapes applied to seal joints between façade panels. They all concluded that it is not safe to rely only on a single layer of foam sealing tape to seal joints watertight as water leakages were observed at low-pressure differences.…”

“…It is expected that the material properties of the foam sealing tapes and installation method have an effect on the watertightness. Van Linden and Van Den Bossche [21] found that the joint width or compression of the foam sealing tapes had an effect on the watertightness. Compressions of open-cell foam sealing tapes, applied between wood panels of 60% to 90% were evaluated.…”

Currently there is gaining interest in pre-compressed foam sealing tapes to seal joints watertight between different building envelope components. Little to no information is available on the parameters affecting the resistance of these foam tapes to driving rain. On the other hand, several research studies have shown that water leakages can be expected at relatively low-pressure differences and that drainage should be provided. Therefore, a study was designed to on the one hand assess the material and installation parameters that affect the watertightness of pre-compressed polyurethane foam sealing tapes impregnated with an acrylic polymer dispersion and on the other hand evaluate the potential of providing drainage possibilities, either as a two-barrier system or by means of integrated drainage cavities. It was found that the joint width, the presence of an airtight coating, and the position of the tape relative to the exterior surface affected the watertightness of the sealed joints. Notably, 87% of the evaluated foam tapes applied as a single barrier showed water leakages at pressure differences of 600 Pa or lower. Foam tapes with integrated drainage cavities, on the other hand, resulted in watertight joints up to an average pressure difference of 825 Pa.
