Warning Signs

Signs Your
Home May Need
Waterproofing

Many homeowners only notice waterproofing problems once water has already entered the structure of the house. Leaks rarely start as a major problem. They usually begin with small failures in membranes, joints, or drainage systems.

Warning Signs

Damp patches on ceilings
Peeling paint on walls
Mould around bathrooms
Water dripping during rain
Stains below upstairs shower
Balcony leaking into rooms

01

Early Signs Of Water Penetration

Common signs include damp patches on ceilings, peeling paint on walls, mold around bathrooms, or water dripping during heavy rain. In double-storey homes, leaking showers often show up as water stains on the ceiling below. Balconies can also leak through the slab and affect rooms underneath.

02

Roof And Flat Concrete Slab Failures

Roof waterproofing problems are especially common on flat concrete roofs where membranes have cracked or aged over time. Once water gets under the surface, it spreads through concrete and plaster, which is why leaks often appear far from the actual entry point.

03

The Cost Of Ignoring The Problem

If these issues are ignored, the damage can spread into ceilings, electrical fittings, cupboards, and flooring.

Residential Waterproofing
Explained

Residential waterproofing is the process of sealing parts of a home that are exposed to water so moisture cannot penetrate the structure.

What Residential Waterproofing Does

What Residential Waterproofing Does

Residential waterproofing is the process of sealing parts of a home that are exposed to water so moisture cannot penetrate the structure.

Different Systems For Different Areas

Different parts of a house require different waterproofing systems. Roof slabs typically need torch-on or liquid membranes that bond directly to the concrete surface. Bathrooms and showers require flexible waterproof membranes installed under tiles to stop water from reaching the slab. Balconies and exterior walls are usually sealed with protective coatings designed to handle weather exposure.

Finding The Source Before Applying Anything

Before applying any waterproofing system, the source of the leak must be identified properly. Many leaks are caused by small cracks, failed joints, or drainage problems. Simply applying coating over the surface rarely fixes the issue permanently.

What Proper Waterproofing Involves

Proper waterproofing involves preparing the surface, repairing cracks, installing the correct membrane system, and sealing vulnerable areas such as corners, outlets, and wall joints.

What We Do

Residential
Waterproofing
Services

Homes can experience water penetration in several areas. Each area requires a slightly different repair approach depending on the structure and materials involved.

01
Roof WaterproofingMost Common

Flat concrete roofs are one of the most common sources of leaks in residential buildings. Waterproof membranes can crack over time due to weather exposure and movement in the structure.

Roof waterproofing repairs usually involve cleaning the slab, repairing cracks, installing a waterproof membrane, and sealing outlets and joints. Torch-on membranes and liquid waterproof systems are commonly used depending on the condition of the roof.

This type of repair prevents water from entering through the slab and protects ceilings and internal walls.

02
Shower & Bathroom Waterproofing

Bathrooms require waterproof membranes beneath the tiles to prevent water from reaching the concrete slab.

When these membranes fail, water slowly seeps through grout lines and tile joints. In double-storey homes this often appears as water stains on the ceiling below the shower.

Repair work may involve removing tiles, installing a new waterproof membrane, and resealing the shower area properly before re-tiling.

Learn more
03
Balcony Waterproofing

Balconies are exposed to constant rain and temperature changes. Over time, tiles and grout can crack, allowing water to penetrate the slab.

Balcony waterproofing usually involves removing damaged tiles, repairing the concrete surface, applying a waterproof membrane, and reinstalling tiles or protective coatings.

This prevents water from leaking into rooms below the balcony.

Learn more
04
Wall Waterproofing

Exterior walls can absorb water during heavy rain, especially when plaster cracks or paint coatings fail.

Wall waterproofing includes sealing cracks, repairing plaster, and applying waterproof coatings that protect the surface while allowing the wall to breathe.

Our Process

Our Repair
Process

Waterproofing repairs begin with identifying where water is entering the structure. Many leaks travel through concrete or plaster before appearing inside the house, which makes inspection important.

The process usually starts with a site inspection to locate the problem area and check surrounding surfaces.

Step 01Start Here

Inspection

The process usually starts with a site inspection to locate the problem area and check surrounding surfaces. Once the source of the leak is confirmed, the repair plan is determined.

Step 02

Remove Damaged Materials

Damaged materials such as loose tiles, cracked plaster, or failed coatings are removed to expose the affected surface beneath.

Step 03

Surface Preparation

The surface is cleaned and prepared so the waterproofing membrane can bond properly. Cracks and joints are sealed before application.

Step 04

Membrane Application

The waterproof system is applied according to the manufacturer's specifications. The correct membrane is selected based on the area and exposure conditions.

Step 05Complete

Seal & Restore

After the membrane cures, the area is sealed and protected. Where necessary, tiles or surface finishes are reinstalled.

Customer Feedback

Customer
Experiences

Homeowners usually contact us when leaks start causing visible damage inside the house. Many problems have been developing for months before the source is discovered.

Case 01 Somerset West

One homeowner in Somerset West noticed brown stains forming on the ceiling below their upstairs bathroom. After inspection, the issue was traced to a failed shower membrane beneath the tiles. The tiles were removed, the surface was waterproofed properly, and the bathroom was reinstalled with a new sealing system. The leak stopped completely.

Leak Resolved
Case 02 Cape Town

Another project involved a balcony leak where rainwater was entering a living room below. The old tiles had cracked and allowed water through the slab. After removing the tiles and installing a new waterproof membrane system, the balcony was retiled and the interior damage stopped spreading.

Damage Stopped

These types of repairs are common in residential buildings where waterproofing systems have aged or were installed incorrectly during construction.

Questions

Questions

Find answers to common residential waterproofing questions.

01How do I know if my house needs waterproofing?

Early signs include damp patches on walls or ceilings, peeling paint, mold growth, and water dripping during rain. Bathrooms and balconies are also common leak areas. If these problems appear, waterproofing failure may be the cause.

02Can waterproofing fix roof leaks permanently?

When the correct membrane system is installed and the surface is properly prepared, waterproofing repairs can stop roof leaks for many years. The key is identifying the real entry point of the water and sealing it correctly.

03Do shower tiles need to be removed for waterproofing?

In many cases, yes. The waterproof membrane sits beneath the tiles, so repairing a failed shower membrane usually requires removing tiles, installing the new system, and then re-tiling the area.

04How long does waterproofing work take?

The time required depends on the area being repaired. Small waterproofing repairs can sometimes be completed within a day, while larger balcony or roof waterproofing projects may take several days.

05What causes waterproofing systems to fail?

Common causes include aging membranes, poor installation during construction, cracks in concrete, blocked drainage outlets, and weather exposure over many years.

06Is waterproofing necessary for new homes?

Yes. Waterproofing systems protect structural surfaces from moisture damage. Proper waterproofing is usually installed during construction in bathrooms, balconies, and roofs to prevent leaks later.

07Can damp walls be waterproofed?

Yes. Exterior waterproof coatings and crack sealing can prevent water from penetrating walls during rain and reduce internal damp problems.
