The strength of a building depends on how well each and every aspect of the building is taken care of. Protection from moist, room for expansion and contraction are key features that add to the lifespan of a building.
A building’s floor slab needs to be protected from absorbing moist: this is achieved by using an appropriate damproofing 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 a flexibility.
