Frequently Asked Questions
What’s the difference between internal and external waterproofing?
Internal waterproofing involves sealing surfaces from the inside—like bathrooms, laundries or basement walls—to prevent water from entering living spaces. It often uses liquid membranes, grouting and sealants to block moisture. External waterproofing, on the other hand, is applied to the outside of a structure, such as foundations or retaining walls, to prevent water from penetrating the building at all. Both are important and are often used together for maximum protection.
Do I need waterproofing if I have tiled surfaces?
Yes. Tiling alone is not waterproof—water can still seep through grout lines or cracks in the tiles. Without a proper waterproofing membrane underneath, moisture can damage the subfloor, cause mould growth, or weaken the structure. Waterproofing is especially important in showers, balconies, and other areas that see frequent water exposure. Even if tiles are intact, worn sealant or missing grout can create pathways for leaks.
Can waterproofing stop mould from forming?
Waterproofing helps prevent mould by eliminating the moisture that mould needs to grow. When walls, floors and joints are properly sealed, water can’t seep into areas where it can sit and stagnate. Combined with good ventilation, waterproofing significantly reduces the risk of mould developing behind walls, under floors or in corners. It’s one of the most effective preventative measures against mould-related damage and health issues.
