The Steyn City Clubhouse’s landscaped roof was waterproofed with a synthetic liner from Master Builders Solutions by BASF.

The Steyn City Clubhouse’s unique landscaped roof was a first for Master Builders Solutions by BASF in green roof waterproofing from their range of synthetic membranes.

Involving 9 000m² of waterproofing, this enormous project required great skill from the applicator as well as specialised products from BASF Construction Chemicals. Specifically, BASF’s MasterSeal® TPO synthetic membranes were specified to waterproof and complete the clubhouse’s planted roof.

Two-colour synthetic liner
MasterSeal® 750TPE is a synthetic liner of TPO-modified polyolefin, in a two-colour version of sand, grey and black. It is obtained by co-extrusion, which allows it to be produced in a single layer, a liner with different physical-chemical properties on the two sides. It also has a polyester mesh reinforcement inserted as a dimensional stabiliser.

The upper-sand grey layer is characterised by an extremely high resistance to weathering and ultraviolet rays, whereas the lower black layer is resistant to puncturing. Thanks to these qualities, BASF offers a product warranty of ten years, with a life expectancy of over 25 years.

Some advantages of MasterSeal® TPO synthetic membranes include:
•    Superior mechanical characteristics.
•    Extremely high resistance to weathering and ultraviolet rays.
•    High mechanical properties and resistance to puncturing.
•    Resistance to root penetration.
•    Resistance to wind stress.
•    Non-toxic and good resistance to hydrocarbons.
•    High environmental capability.
•    Tolerance of pressure testing of joints if it is double-welded.

The Steyn City Clubhouse project was done over a year and BASF together with the waterproofing consultant for Steyn City, Alan Gatley, and Storm Waterproofing as the applicators, ensured the successful completion of this complex task.
