Sealing Sewerage and air ventilation

To better protect your home against water damage and flooding, we offer various innovative solutions for sealing the sewer system against external overpressure. These methods ensure an effective and reliable water seal.

Sewerage and Toilet Shut-off

The inflatable ball can be used as a seal in the toilet. This ball is placed in the bend of the toilet and inflated tightly. This is very simple, but effectively prevents water from flowing back out of the toilet, protecting you against unwanted water infiltration.

For the sink, utility basin, or other drain openings, there are various sizes of inflatable balls that ensure the external water pressure is shut off when necessary. This offers extra protection against flooding in case of emergency.

Shut-off check valve

If possible, a large, sturdy 110mm PVC check valve can be installed on the main line, or an inflatable balloon inside the pipes. With these two methods, you make it possible to shut off the entire house quickly and easily, effectively preventing water damage caused by external overpressure resulting from storms and floods.

Waterproof wall ventilation

Cavity wall ventilation and low ventilation grilles are the first point of water inlet when water rises and flows into the crawl space, basement, or cavity wall. The ventilation brick (225 × 75 mm) provides normal ventilation, but as soon as water reaches the brick, an internal float closes the passage. No electricity required, no intervention needed, BBA and BSI certified. Available in two colors (red, gray).
