Commercial Kitchen Waterproofing Solutions

Water leakage in commercial kitchens is a common issue in restaurants, food courts, and shopping malls. As kitchens operate continuously and exposed to frequent washing, grease and heat, leakage can quickly seep beneath floor finishes and migrate into adjacent units or lower floors, potentially disrupting operations and violating building or hygiene requirements.

It may be surprising, but water leaks frequently occur in kitchens, often due to plumbing issues or worn-out fixtures. If you’re facing this problem in your business or home, you’re not alone. Many business owners and homeowners encounter similar issues, making it a common concern in residential and commercial spaces.

Kitchen leaks are a common problem in Malaysian buildings, often causing structural damage, mould growth, and frequent complaints from residents if not detected and repaired promptly.

Signs & Causes of Water Leakage in Your Kitchen

If you notice these signs, it’s essential to address the root cause. Many homeowners and building owners overlook small kitchen leaks, assuming they’re minor. However, unaddressed leaks can damage your building’s structure and pose health risks to occupants, making prompt action crucial.

  • Warped Cabinet or Flooring Around Appliances

    Leaks from appliances usually happen underneath or behind them. The water can soak into cabinets or flooring, leading to swelling, warping, and long-term damage.

  • Low Water Pressure

    Sudden low water pressure when you turn on a faucet can be caused by a leak elsewhere, which may divert water flow from a completely different part of your home.

  • Puddles or Dampness

    Leaks from worn faucets, pipes, or damaged seals can drip over time, causing water seepage. Months or years later, yellow stains may appear on ceilings, walls, or under sinks, gradually damaging your home.

  • Musty or Damp Odors

    Slow, continuous leaks keep an area persistently damp. This trapped moisture encourages rapid growth of mold and mildew, which produces the earthy, musty smell.

Why Kitchen Leaks Keep Coming Back

Compromised or absent waterproofing allows water and grease to seep into the substrate, causing recurring leaks.

Replacing tiles or sealant treats the surface, not the underlying waterproofing, so leaks quickly return.

High traffic, constant moisture, and chemical exposure in commercial kitchens require specialised waterproofing, standard systems fail under these conditions.

Uneven or dirty substrates prevent proper adhesion, reducing the durability of the waterproofing layer.

Leaks often occur at corners, drains, and junctions if membranes aren’t fully continuous and well-detailed.

ARCHTECH’s Approach to Kitchen Water Leak Solutions

We provide a systematic, long-lasting solution that protects your property from leaks, mould, and structural damage. Here’s how we do it: 
  • 1

    Root Cause Inspection

    Our specialist inspects the commercial kitchen to identify the actual source of leakage. This includes assessing floor finishes, waterproofing continuity, drainage points, service penetrations, and operational conditions before recommending any repair approach.
  • 2

    Surface Preparation & Repair

    Once the cause is identified, necessary preparatory works are carried out. This may include removal of existing finishes where required, surface preparation, and rectification of affected areas to ensure suitability for waterproofing installation.
  • 3

    Waterproofing System Application

    Based on the operating environment and usage requirements of commercial kitchens, a sanded torch-on membrane system is applied to form a durable and slip-resistant waterproofing layer beneath floor finishes. This system is selected to withstand frequent washing, moisture exposure, and heavy usage.
  • 4

    Reinstatement & Final Inspection

    After waterproofing works are completed, floor finishes are reinstated where required, followed by final inspection to ensure proper application before handover.

The solution leaves your area fully sealed and dry, providing lasting protection against leaks and daily moisture.

Frequently Asked Questions

The source of a kitchen leak isn’t always obvious. It could be due to worn waterproofing, cracked grout, pipe issues, or structural movement. Our trained specialists will carry out a detailed inspection to diagnose the exact cause before recommending the right solution for your space.

Not always. The best approach depends on the condition of your kitchen, the type of leakage, and the materials used. Our technician will assess the site and recommend the most suitable and cost-effective solution, whether that involves surface treatment or more extensive repair.

The duration of the job varies depending on the severity of the leak and the repair method needed. Some solutions can be completed in a day, while others may take several days. We’ll provide a clear timeline after our on-site assessment, and we always aim to minimise disruption to your daily routine.

Yes. If the inspection shows that the leak is due to plumbing problems — such as damaged or leaking pipes — our team can handle the necessary repairs alongside the waterproofing work. We offer a full-service solution so you don’t need to coordinate with multiple contractors.

In many cases, partial use of the kitchen is possible during the repair period. However, depending on the scope of work, we may advise limiting certain activities. Our team will guide you on how to manage usage during the process and will work efficiently to restore full access as soon as possible
