What the service includes
Waterproofing is about more than applying a coating. It starts with understanding why water is getting in, where the surface is failing and what movement the building will experience over time. Indawo uses that approach to match the correct system to the right surface, whether the problem sits on a roof slab, a parapet wall, a balcony, a retaining wall or a junction detail.
A good waterproofing job protects the asset and reduces expensive repeat repairs. For commercial buildings, that often means balancing performance with practical access, because the best system is the one that is installed correctly, maintained sensibly and suitable for the building’s operating conditions.
Who needs it
Anyone managing a building that has leak risks, standing water, ageing membranes or cracked surfaces needs waterproofing at some stage. The service is especially important for properties with sensitive interior finishes, electrical plant, archives, retail stock or tenant environments that cannot afford repeated water ingress.
Compliance and safety
Some waterproofing jobs happen at height, some happen over occupied areas and some involve substrate preparation that must be managed carefully to avoid damaging the structure. We plan the work so the right products are used in the right sequence and the site remains safe during the installation window.
Buildings we serve
We work on commercial offices, retail centres, warehouses, apartment blocks, schools and heritage properties. Those buildings often have different movements and exposure conditions, so a flexible system selection is essential rather than simply repeating one generic product across every surface.
Project examples and FAQ
Example: a flat roof with recurring leaks may need failed membrane removal, substrate preparation, new flashings and a more durable waterproofing build-up. Example: a balcony or parapet repair may need crack treatment, priming and a surface finish that resists weathering without compromising movement.
FAQ: Clients often ask how long a waterproofing system should last. That depends on exposure, maintenance and the quality of the installation. Another common question is whether a leak inside the building always means the roof is the only problem. Not always. Water can travel through multiple points before it shows up indoors.
