About Waterproofing
Roof and terrace waterproofing basics
Flat roofs and terraces need a continuous membrane over the entire surface. Options include torch-applied bituminous sheets, liquid polyurethane, or EPDM rubber. Joints around drains, edges, and pipes are the most common leak points. Proper slope toward drains prevents standing water after rain.
Common signs you need waterproofing work
Look for damp patches, peeling paint, white salt deposits, or a musty smell. Brown stains on ceilings often point to a roof or upper-floor leak. Hairline cracks in basement walls let water seep in during rain. Bubbling wallpaper and swollen skirting boards are also warning signs to act on.
Maintenance after waterproofing is done
Inspect gutters every 6 months and clean them so water flows away from the walls. Check seals around vents and pipes once a year for cracks. Keep an eye on basement walls for new stains after heavy rain. Trim plants 30 cm away from exterior walls so roots do not damage the membrane. Small habits keep the system working for many years.
What usually goes wrong with waterproofing
Common failures come from poor surface preparation, skipping primer, or applying membrane on a wet slab. Joints that are not overlapped correctly also leak within months. Some contractors use thin paint instead of real membrane, which peels after 1 or 2 seasons. Lack of drainage behind retaining walls causes water to build up and push through the coating.
Questions to ask the professional before hiring
Ask which materials they use and why, how thick the membrane will be, what warranty they offer in writing, and whether they handle excavation or hire a subcontractor. Request photos of similar past jobs and ask for a written scope of work. Confirm they carry liability insurance and a local trade license. Clear answers build trust from day one.
Bathroom and wet area sealing
Showers and bathroom floors need a waterproof layer under the tiles. Professionals apply liquid membrane in 2 or 3 coats, letting each one cure for 4 to 6 hours. Corners get reinforcing fabric tape. Coverage should reach 20 cm above the showerhead. This stops water reaching the slab and prevents damage to the ceiling of the room below.
Interior versus exterior waterproofing methods
Interior methods include sealants, epoxy injections and negative-side coatings applied inside the basement. Exterior work usually needs excavation around the foundation, a bituminous membrane 3 mm thick, and a drainage board. Exterior systems block water before it reaches the wall, while interior ones manage water that already entered. Both can be combined for stronger protection.
Why waterproofing matters at home
Waterproofing protects concrete, plaster and wood from moisture that causes mold, swelling and cracks. When water enters through walls or floors, it lowers air quality and damages finishes. Catching the problem early saves money on later repairs to paint, furniture and even the electrical system. A dry home stays healthier for everyone inside it.
Maintenance after waterproofing is done
Inspect sealed areas every 6 months for cracks or bubbles. Keep gutters and drains clear to avoid water buildup. Reseal joints in wet areas when grout starts to crack. Avoid drilling into waterproofed walls without proper guidance. Small repairs early prevent large leaks later.
What usually goes wrong with waterproofing
Bad surface preparation causes most failures. Applying membrane over dust, moisture, or loose material leads to peeling. Using the wrong product for the substrate is another common mistake. Skipping primer or using cheap sealants reduces durability. Poor detail work around drains and joints also causes leaks.
