Cement Repairs via Panel Joint Sealing
What is Precast Panel Joint Sealing?
Precast panel joint sealing is the sealing of the joint type between precast concrete panels. The joints, between the precast elements, provides physical separation between the panels and, in conjunction with the joint sealant, accommodates movement and protects against the ingress of water, air, chemicals, smoke, etc. With joint sealants fully exposed to ultraviolet light and thermal cycling, the major elements of aging and deterioration, it is crucial that high performance sealants, with high movement capability and low modulus, are used to ensure long term performance. Precast panel joint sealing is crucial to maintaining the integrity of the concrete structure.

Why panel joints fail?
While sealants may be only a small portion of a building’s exterior, they perform a very large function. The most common causes of panel joint sealing failure are as follows:
Inappropriate Joint Design
In an effort to preserve the aesthetics of a building façade undersized/oversized joints, too few or incorrectly placed joints are often a major cause of failure.
Unsuitable Sealant Selection
When a joint is correctly sized and located, the most common cause of failure is the use of a sealant which not only lacks sufficient movement capacity for its intended use but also not appropriate for the environment in which it’s expected to perform.
Incorrect Surface Preparation and/or Application Technique
If just one step of the surface preparation or application procedure is missed or not completed correctly this could cause contamination, adhesion problems, etc.; resulting in failure of the sealant.
