Cement Repairs via Panel Joint Sealing

What is Panel Joint Sealing?

The use of precast concrete panels has increased in popularity over recent years. Well detailed and constructed joints are critical in ensuring that the structural integrity of the building is maintained and that is weatherproof, compliant to fire resistance codes and has suitable acoustic performance.

Panel joint sealing is undertaken by sealing the joint type between the precast concrete cladding and the wall panels. The function of a joint between precast elements is to provide physical separation between the panel and, in conjunction with joint sealants, prevent the ingress of water and air into the building. Additionally, the joint creates a strong visual feature of architectural all design.

When panel joints fail?

Panel joints, a majority of the time, are done in new build construction and are only used for concrete panel installation. However, there are reasons, that a panel joint might fail, these are:


If the structure is rather old and dilapidated, then the panel joint could start to show signs of peeling away and failure.


If a structure doesn’t have the proper support installation to allow for movement, then the panel joint can fail.

Inappropriate application

If dirt remains on either side of the concrete panels before the panel joint is applied, then it has a higher risk of it not being properly sealed and penetrable.
