Waterproofing

Home » Services » Waterproofing

Waterproofing of concrete is essential in maintaining the integrity of your building and its structure.

Concrete expands and contracts in different weather conditions. Over time when concrete moves like this it often leads to cracks and if not properly waterproofed it will cause concrete cancer and spalling.

The long-term structural integrity of concrete is largely dependent on the quality of the waterproofing applied to the structure.

If you want to avoid costly repairs and remediation work to your building structures, it is important that high quality waterproofing applications are correctly applied.

Waterproofing represents 1.8% of a building’s construction costs, but accounts for a whopping 83% of building defect complaints. These are costs that can be easily avoided or minimised if quality waterproofing is applied in the first instance.

Sustainable waterproofing applications are required for:

Balconies

Walkways

Terraces / decks

Planter boxes

Retention walls and basement walls

Concrete roof tops, green roofs & landscaped areas

Podium slabs

Car parks & Basements

Lift pits

Portable water tanks

Detention, retention, header & dump tanks

Any other concrete wet area where water flowing through cracks can cause leaching and corrosion.

Remedial Waterproofing Solutions

Where waterproofing has failed and a structure is showing signs of concrete cancer and spalling, it is critical to correctly diagnose the problem. It is best to use specialist structural engineering consultants who can assess and test for structural issues.

Once the root cause of waterproofing failure, concrete cancer, or concrete spalling is identified, the process of repair can commence. The type of repairs required will depend on the type of structure and its location, the building materials used, and the extent of the damage.
