Hair cracks have been spotted on the façade of the Forum; these are caused by exposure to extreme heat and cold. Elastic mortar should fix that.
When buildings 'work', they are affected by temperature. They shrink and expand. This is taken into account during construction. But such efforts seem to have fallen short in the case of the Forum, and small cracks are visible in many parts of its façade. To prevent these from getting worse, the façade needs to be made more elastic, explains Ludy Zeeuwen of Facilities & Services.
After a row of bricks is removed, it will be replaced by a row of smaller bricks with a wider and elastic filling. The filling should make the building more resilient. Work has begun this week on the north and the west faces. Drilling causes noise pollution and is therefore being carried out now during the autumn break.
The filling will be done next week, says Zeeuwen. Drilling will continue in the week after on the east face and the south face behind which the library is located. During drilling, no examinations will be held, says Zeeuwen. Afterwards, the new row of bricks will be laid. The work will therefore certainly last another three weeks.
