Choosing the right waterproofing system and waterproofing membrane with good properties such as tensile strength, elongation and crack bridging ability is highly essential to withstand the harsh outdoor environment.
Waterproofing systems that are protected with a protective mortar screed is always recommendable because we always want the acting barrier of the waterproofing system to be the last line of defence from water infiltration.
If waterproofing systems are exposed, it is essentially being put as the first line of defence from harsh conditions such as hot temperature from direct exposure to sunlight, heavy rainfall and UV ray attacking the membrane.
The protective mortar screed can be installed with a slope to fall above the Roof top Waterproofing system which will serve two important functions: a diversion for rain water and extra protection over the waterproofing system.
