Waterproofing Solutions for Laundry Room Plumbing in Homes

Picture a laundry room: a washing machine, a sink, and a plumbing system which comprises water supply lines, a drain line for the washing machine, a floor drain, and more. It is easily understood that the whole area undergoes constant water usage and occasional spills or leaks. So, homeowners must consider waterproofing solutions for their laundry room plumbing. This article reveals the benefits of a hygienic, efficient laundry room and shares the top 5 waterproofing solutions to achieve it.

Benefits of Waterproofing Laundry Room Plumbing

• Prevents corrosion of metal parts: Waterproofing secures plumbing fixtures from rust due to moisture build-up. It keeps the pipes firm, preventing leaks and cracks.
• Wards off termite infestation: Termites are attracted to damp environments, and their presence is repulsive and causes stains. Fending them off with waterproofing promises a neat and hygienic space. 
• Reduces accidents due to slippery floors: frequent use of water results in water accumulation on the floor which could lead to accidents. Waterproofing creates a moisture barrier that keeps water from pooling on surfaces and enables faster drying.
• Protects inhabitants from short circuits: By sealing floors, walls, and fixtures near the washing machine and other wiring, waterproofing blocks water from these sensitive areas. It minimises the risk of accidental water exposure to electricity. 

5 Waterproofing Solutions for Laundry Room Plumbing 

1. Waterproof Membrane

Apply a waterproof membrane on floors and walls before laying tiles. This membrane resists water from seeping into the concrete and causing damage. If you have laundry rooms located on the upper floor, this technique becomes especially beneficial as leakage could affect the rooms below.

2. Epoxy Grouting

Unlike traditional cement grout, epoxy grout creates a non-porous, durable barrier. It effectively blocks water from seeping through the gaps. Also, its strength and resistance to cracks and staining make it an excellent choice for long-lasting waterproofing.

3. Slope Adjustment and Floor Drain

Make sure your laundry room has a slight floor slope toward a floor drain. Water stagnation could occur near the washing machine, and a system comprising a sloping floor and a floor drain is mandatory.

4. Waterproofing Tapes and Covers for Joints

Purchase waterproof tapes and pipe covers to adhere to pipe joints. If there are any poorly sealed connections of the washing machine due to high water pressure, these tapes and covers will be a suitable backup.

5. Backflow Preventer Installation 

In areas prone to flooding in the monsoon, it is useful to have backflow preventors on drainage outlets. It prevents the foul-smelling wastewater from backing up into the laundry room during drainage issues.
