Eastgate Shopping Centre was experiencing major water ingress through the rooftop parking deck, which was causing damage to ceilings, tenants stock and was an eyesore to customers. After an extensive site inspection, it was confirmed that the existing jointing system on the rooftop parking area had perished and accounted for 80% of major water ingress.

The existing jointing system utilised a closed cell on the structure gap, which had deteriorated and become brittle. The anchor bolts had penetrated through the underlying membrane, all which allowed for major water ingress. The success of this type of a project is directly related to the quality of the expansion joint.

Eastgate had called upon numerous waterproofing specialists, and all had failed to contain the leaks from the rooftop parking deck expansion joints.


Eastgate, along with facility manager, Excellerate, contracted Sanika Waterproofing Specialists to replace the existing jointing system after conducting in-depth research and a year-long trial of the joint was found to be a great success.

Sanika Waterproofing Specialists have cemented their position over 25 years as a leader in the waterproofing industry in Southern Africa, while Emseal have provided watertight expansion joints for thousands of projects worldwide for over 30 years. Sanika are the exclusive distributor and an approved applicator of Emseal products in Southern Africa.

In addition to being 100% watertight and providing the best guarantees in the industry, the Emseal SJS Expansion Jointing System utilises a less invasive application as the anchor bolts are not adhered to the substrate, but rather to the centre of the joint.

Other expansion jointing systems are not able to handle multi-directional movement as the system relies on the underlying EPDM Membrane, however, Emseal SJS Expansion Joints can handle multi-directional movement in these high traffic areas. While other jointing systems do not allow for heat welding which causes leaking at transitions and terminations, Emseal SJS Expansion Joints have custom made transitions that maintain continuity of the joint to avoid any water ingress.

The Emseal range in conjunction with Sanika Waterproofing Specialists offers expansion joint covers and sealants that are waterproof, fire rated, trafficable, sound attenuating, insulating, air, wind, seismic, and watertight for immersed, interior and exterior structures, stadiums, bridges and below grade.

Although the Eastgate expansion jointing project is still ongoing, Eastgate Shopping Centre tenants that had experienced severe water ingress via the rooftop parking deck expansion joints have had complete water tightness since the completion of the Emseal SJS Expansion Jointing System in specified completed areas by Sanika Waterproofing Specialists.
