About Waterproofing
Interior versus exterior waterproofing methods
Interior methods include sealants, epoxy injections, and waterproof coatings applied inside the room. Exterior work uses membranes, drainage boards, and protective coatings on the outside of the structure. Exterior solutions are usually more durable because they block water before it enters the wall.
Roof and terrace waterproofing basics
Flat roofs and terraces use torch-applied membranes, liquid polyurethane or PVC sheets about 1.2 mm to 1.5 mm thick. Joints need overlap of at least 10 cm and proper sealing at edges and pipes. Good drainage slopes of 1.5 percent keep water from standing. Regular checks every 6 months help you catch small problems before leaks start.
Basement and foundation protection
Basements face constant pressure from groundwater. Common solutions include exterior bituminous coating, dimpled drainage membranes, and interior sump pumps. Cracks wider than 3 mm usually need injection repair. Good exterior drainage with clean gutters and downspouts reduces hydrostatic pressure.
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.
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.
How professionals price waterproofing work
Pricing depends on area size, access difficulty, material type, and how much preparation the surface needs. Interior sealants may cost less per square meter than full exterior excavation jobs. Labor, disposal of excavated soil, and the number of coats required all change the final price. Always compare written quotes covering the same scope of work and materials.
How to choose a reliable waterproofing contractor
Look for a contractor who specializes in waterproofing, not just general repairs. Check references from jobs done at least 2 years ago. Confirm liability insurance and written warranty. A good contractor inspects the source of the leak before quoting. Avoid anyone who suggests covering the problem without diagnosis.
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.
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.
Bathroom and wet area sealing
Showers and bathroom floors need a liquid membrane under the tiles. Corners, pipe entries, and the floor-wall joint require flexible tape or reinforcement mesh. Grout alone is not waterproof and must be sealed. Re-sealing every 2 to 3 years keeps the area watertight.
