The strength of a building depends on how well each and every aspect of the building is taken care of. Protection from moisture, room for expansion and contraction forces are key features that add to the lifespan of a building.
A building’s floor slab needs to be protected from absorbing moisture: this is achieved by using an appropriate dampproofing membrane.
In addition, a building should have room for expansion and contraction during hot and cold weather conditions respectively. A right expansion joint filler accords a building such flexibility.
