MRC Group is the only supplier, installer and maintainer of torch-on, liquid applied and single-ply membrane waterproofing systems in southern Africa, who backs their work with the Guardian™ System Warranty covering materials, workmanship and maintenances for up to ’20 years.’

Waterproofing systems have been used throughout southern Africa for centuries with some of the earliest forms being liquid bitumen and torch-on systems. Over the centuries waterproofing design has developed to consider the project location, building size, shape & height, the operation within the building, wind loads and water management. Waterproofing systems are generally used as a quick, flexible, economic and easy to repair and maintain solution. The vast array of waterproofing systems available in the marketplace provide the specifier with a large range of materials and colours to suit the requirements of the project.

Waterproofing Design:

Although a lot of time can be spent on the specification and choice of materials and colours, one of the important areas which can be neglected is the design of sealing the perimeters, junction points and penetrations. If their is a leak in a building in most cases the perimeter, junction points and penetrations details are the areas that have not be accurately constructed.

The nature of the substrate is important when choosing the correct waterproofing system, as different substrates behave thermally in different ways, which will have a direct impact on the ability of the system to keep water to of the building. In most cases the ‘one size fits all’ fails the long term performance of the building.
