Shower
Waterproofing
Cape Town
A leaking shower can quietly damage floors, ceilings, and walls. We inspect the problem, repair failed waterproofing systems, and seal the shower properly so water stays where it belongs.
Signs Your Shower Is Leaking
Most shower leaks don't start with a burst pipe. They usually begin slowly under the tiles where the waterproofing layer has failed. Homeowners often notice small warning signs first.
- Grout between tiles begins cracking
- Silicone seals pull away from corners
- Tiles sound hollow when tapped
- Water stains on ceiling below bathroom
- Damp walls around the shower area
Many bathrooms were tiled without proper waterproofing, especially in older homes. Over time, water seeps through the tile bed and starts affecting the structure beneath the shower floor. If left untreated, this can lead to mould growth, damaged ceilings, loose tiles, and costly repairs to surrounding rooms.
WE DON'T CUT
CORNERS.
Shower waterproofing requires careful preparation and the correct materials. Our technicians work with professional waterproofing systems designed specifically for wet areas such as bathrooms and balconies.
Professional waterproofing systems for wet areas
Full inspection before recommending any repairs
Proper surface preparation and joint sealing
Waterproof membranes installed where required
SERVICES WE PROVIDE
Waterproofing problems vary by structure, tile system, and drainage. We match the right solution to each condition.
Shower Leak Detection
We inspect grout lines, silicone joints, drains, and tiles to pinpoint where water is escaping.
Waterproofing Repair
Failed membranes removed and replaced with a new flexible system. Only affected sections opened.
Bathroom Waterproofing
Full wet-area protection covering shower floor, walls, and bathroom floor areas exposed to water.
Waterproofing Over Tiles
Coatings applied over existing tiles after surface prep. Ideal for minor cracks or grout failure.
Grout Repair & Sealing
Deteriorated grout replaced with waterproof systems that block moisture penetration.
Silicone Joint Sealing
Old brittle silicone replaced around corners, frames, and trays to restore watertight seal.

Request InspectionOUR REPAIR PROCESS
Every shower leak is slightly different, but the repair process usually follows these steps.
Inspection
We check the shower area, grout joints, drainage points, and identify moisture around walls or ceilings.
Surface Preparation
Tiles, grout lines, and surfaces are cleaned. Loose grout, damaged silicone, and cracked sections removed.
Sealing Joints
Corners, pipe penetrations, and drains sealed using flexible waterproof compounds for wet areas.
Membrane Installation
Liquid waterproof membrane applied across the shower base and wall joints with reinforcing fabric.
Curing & Final Seal
Grout joints and silicone seals replaced. The system forms a continuous waterproof barrier.

MATERIALS
& SYSTEMS
We work with professional waterproofing systems used in the construction industry, including membranes and sealants from brands such as Sika, ABE Construction Chemicals, and similar high-performance waterproofing products.
These systems are designed to remain flexible and resist cracking in wet environments.
Liquid Waterproof Membranes
Flexible coatings applied in liquid form beneath tiles. Self-sealing over minor cracks — ideal for shower floors and wet areas.
Reinforced Waterproof Tape
Embedded into coatings at corners, joints, and drain areas to strengthen the membrane against movement and cracking.
Flexible Joint Sealants
Applied at pipe penetrations, wall-floor junctions, and shower trays. Stays flexible as the building shifts.
REAL JOBS.
REAL RESULTS.
Many customers are surprised to learn that tiles alone do not stop water. Once the waterproof layer beneath the tiles is restored, the shower becomes watertight again.
Water had been leaking into the bedroom below during every rain. The tiles looked fine — the problem was invisible from the surface.
Waterproof membrane beneath tiles had deteriorated, allowing water to reach the ceiling below.
Removed affected shower floor sections and installed a new waterproof membrane. Leak fully resolved.
Mould kept appearing around the shower wall joints no matter how often we cleaned it.
Deteriorated silicone seals combined with cracked grout lines were allowing moisture behind tiles.
Resealed all joints and applied a flexible waterproof coating system across the shower area.
They found the leak in my shower wall before it destroyed the ceiling below. Fast and professional.
Cracked grout lines were directing water behind the tiles into the wall cavity.
Grout removed and replaced with waterproof sealant. Wall joints resealed with flexible membrane.
The repair was done quickly and the waterproofing has held up through two full winters now.
Original waterproofing had failed due to age. Water was tracking through the concrete slab.
Full shower floor membrane replacement with reinforced fabric at all joints and corners.
Water was coming through into my kitchen cupboard until they sealed the shower properly.
Shower drain area had no waterproofing. Water was escaping at the drain connection point.
Drain area rebuilt with proper waterproof collar and new membrane applied across the shower base.
No more water stains on the ceiling below and the repair cost less than I expected.
Hairline cracks in the shower floor grout were allowing slow water penetration over time.
Applied waterproof coating system over existing tiles after thorough surface preparation.
The shower floor tiles stopped moving and the grout lines stay dry now after the repair.
Loose tiles indicated water had compromised the adhesive layer beneath the shower floor.
Tiles removed, new membrane installed with reinforcing fabric, tiles re-laid on waterproof base.
They explained exactly where the waterproofing had failed and what needed fixing. No guesswork.
Silicone joints at wall-floor junction had separated, creating a direct water path into the structure.
All silicone joints replaced with professional-grade sealant. Corners reinforced with membrane tape.

QUESTIONS
Find answers to common shower waterproofing questions.
Still have questions?Common signs include water stains on the ceiling below the bathroom, cracked grout lines, mould around the shower area, or damp walls next to the shower. If tiles sound hollow or grout keeps breaking, water may be penetrating beneath the tile surface.
In some cases, yes. If the leak is caused by grout failure or small cracks, it may be possible to seal the shower using specialised waterproof coatings applied over existing tiles. However, if the waterproof membrane beneath the tiles has failed completely, some tiles may need to be removed.
A properly installed waterproof membrane can last many years. The lifespan depends on the materials used, how well the system was installed, and whether the grout and silicone joints are maintained over time.
The most common cause is failure of the waterproof layer beneath the tiles. Other causes include cracked grout lines, deteriorated silicone seals, poor tile installation, and movement in the building structure.
Minor sealing repairs can sometimes be completed in a single day. Repairs that require tile removal and waterproof membrane installation may take several days because the waterproof coating needs time to cure properly before the shower can be used again.
Tiles provide a durable surface but they are not completely waterproof. Water can pass through grout joints and tiny cracks. The true waterproof protection comes from the membrane installed beneath the tiles.
Yes. Water from a leaking shower often travels through the concrete slab and appears on ceilings or walls in rooms below or next to the bathroom. Fixing the leak early prevents further structural damage.
Yes. Professional bathroom construction requires waterproof membranes in wet areas such as showers, bathroom floors, and wall joints exposed to water.
