Commercial and Industrial Waterproofing. Cape Town and Western Cape

A leak in a warehouse, retail space, or office building isn't just a maintenance issue. It's stock at risk, downtime you can't afford, and a repair that has to happen without shutting the doors. You need it fixed properly, documented for your records, and done in a way that doesn't disrupt the business.

We understand that commercial and industrial properties can't work around a contractor the way a private home can. Operations continue, staff and customers are on site, and any waterproofing work has to fit around that reality.

Sealtek Cape has accredited waterproofing contractors across the Western Cape who specialise in commercial and industrial applications, from retail centres and office buildings to warehouses and manufacturing facilities. Work is carried out with minimal disruption to your operations, and every project is backed by a 5-year written guarantee covering materials and workmanship.

Commercial and Industrial Waterproofing Services

Commercial and industrial buildings face waterproofing demands that go beyond typical residential work: larger surface areas, structural complexity, and operational constraints that limit when and how work can be carried out.

Every project starts with an on-site assessment of the structure, the existing waterproofing condition, and the operational schedule, so the work plan fits around your business rather than the other way round.

What Our Commercial and Industrial Waterproofing Services Cover

Flat roof waterproofing

Commercial flat roofs face poor drainage and structural loading. Sealtek liquid systems create seamless barriers that accommodate building movement whilst resisting ponding water

Metal roof protection

Industrial facilities commonly use metal roofing that is susceptible to corrosion. Sealtek products create protective barriers that prevent rust whilst maintaining structural integrity

Concrete structure waterproofing

Parking decks, foundations, and structural concrete need protection from water infiltration that causes reinforcement corrosion

Below-grade waterproofing

Basements, underground parking, and foundation walls that face hydrostatic pressure and ground moisture

Preventative maintenance programmes

Scheduled inspections that extend system life and help maintain warranty compliance

Every Facility Type Has Different Requirements

Retail and office buildings

High foot traffic areas need waterproofing that maintains appearance whilst withstanding constant use. We coordinate application schedules around your operating hours to avoid interfering with occupancy.

Warehouses, factories, and manufacturing facilities

Industrial environments involve exposure to chemicals, extreme temperatures, and mechanical vibration from machinery. Sealtek products are formulated to withstand these industrial exposures whilst accommodating the building movement that occurs in large structures.

Distribution centres

Large-scale facilities where operational continuity matters. Because liquid systems apply in sections, portions of the building can remain in use whilst adjacent areas are being treated.

Parking structures

Concrete parking decks face constant vehicular loading alongside water and moisture exposure. Waterproofing protects the structural concrete from reinforcement corrosion whilst withstanding the traffic the structure carries.

Large-scale commercial and industrial projects demand more than product knowledge. They demand contractors who can manage substantial square metreage, work around operational schedules, and document the work properly for compliance and insurance purposes.

Sealtek Accredited Applicators complete training covering application techniques, surface preparation protocols, and problem-solving for complex substrates. They work to certified installation procedures with multi-stage quality control checkpoints, which means the work can be documented: what was done, how it was done, and by whom. That matters when you need records for compliance or insurance.

What to Expect When You Contact Us

Step 1: You get in touch.

Tell us about the property, the issue, and any operational constraints we need to work around. We’ll connect you with the accredited contractor in your area.

Your local contractor inspects the structure, evaluates the existing waterproofing condition, and discusses scheduling that minimises disruption to your operations.

Step 3: Quote and specification.

The quote reflects the scale of the project, the products required, and a schedule structured around your business needs.

Step 4: Professional installation.

Because liquid systems are applied cold with no open flame, work can often proceed in sections without requiring a full building shutdown. The 5-year written guarantee applies from completion.
