WATERPROOFING OF PIPE COLLAR - SMALL DETAIL BUT BIG SOURCE OF LEAKAGE

1. Pipe Neck - The Most Formidable Leakage Location

The pipe collar is where the water pipe passes through the concrete floor, commonly found at:

- Toilet, bathroom (drain pipe, exhaust pipe).

- Balcony, terrace (rainwater drain).

- Washing machine area, manhole.

Although small, this is a potential leak if not properly waterproofed from the start. Many houses leak water from the ceiling under the toilet just because of a defect in the upper floor pipe collar.

2. Why is the pipe neck susceptible to leakage?

- Natural gap between plastic pipe and concrete floor due to shrinkage or poor construction.

- Do not treat waterproofing materials around pipes - water seeps through capillary action.

- Difficult to observe location, often overlooked or done carelessly.

- When water accumulates around the neck of the pipe (toilet or rain), it creates pressure that pushes the water down.

3. Consequences of ignoring pipe collar waterproofing:

- Water leaks from the pipe neck, the ceiling below is yellowed, the paint is peeling, the lights are broken.

- Unsightly and causes unpleasant musty smell.

- Had to re-drill the toilet floor to fix it - very expensive and unsanitary.

- Causes damage to wooden floors, tiles, and surrounding equipment.

4. Technical procedure for waterproofing pipe collars:

For new construction:

- Assemble formwork around the pipe neck.

- Apply Sika Latex adhesive agent mixed with oil slurry to enhance the adhesion of the material.

- Wrap the expanding rubber strip around the circumference of the pipe neck, taking care to use the lap joint.

- Finally, fill the formwork with Sika Grout and wait for it to dry.

- Test by soaking in water for 72 hours.

For pipe necks that have been leaked and need to be re-waterproofed:

- Remove the old concrete layer around the pipe neck and clean the surface thoroughly.

- Apply Sika Latex adhesive agent mixed with oil slurry to enhance the adhesion of the material.
