Cost effective waterproofing scheme for The Hub

Cost effective waterproofing scheme for The Hub

Delta Membrane Systems provided a cost effective scheme for a troublesome leaking podium deck to the entrance of The Hub, Hattersley, Greater Manchester.

The Hub is a landmark building forming an integral part of a new district centre completed in 2012. The £4m project was designed specifically with a “people” focus, to bring people from different backgrounds together under one roof.

Delta Registered Installers, Timberwise were approached by the customer to provide a guaranteed, cost effective scheme that would comply with both BS8102:2009 and any requirements of third-party warranty providers.

A robust waterproofing system needed to be designed for a troublesome leaking podium deck to the entrance of The Hub. Resulting problems from the leaking podium led to high volumes of water ingress to the underground parking facilities.

Following a full assessment of The Hub and its underground parking facilities it was identified that rainwater was entering the basement car park through the ceiling deck at multiple points.

The project commenced by removing all flagstones from the paving area to the front of The Hub and attention was given to the wall floor junction/fillet seals to building perimeter and inner perimeter walls.

Koster Polysil TG 500 was applied to both the junctions slab and fillet. Koster Polysil TG 500 is a free lime and salt encapsulating primer that actually modifies mineral surfaces and effectively consolidates the surface where the waterproofing is to be applied.

An initial application of Koster Deuxan 2C was applied to the external perimeter wall and Deck. Koster Deuxan 2C provides a completely impervious layer that bonds over the whole surface removing issues associated with jointing during the installation process.

Glass fibre mesh was incorporated into the first application of Koster Deuxan 2C prior to a second coat application. The combination of Deuxan 2C and Glass Fibre mesh provides crack bridging properties, the Deuxan 2C is as versatile as it is effective in providing a robust waterproofing solution.

The final stage was to overlay the Deuxan 2C with Delta Gro Drain Quattro to the external perimeter wall. Delta Geo Drain
Quattro is designed to drain excess water away from a structure, offering further protection to the structure.

Delta Geo Drain Quattro is a unique four-layer drainage and protection board that also features a slip layer to further protect proprietary waterproofing systems and deal with lateral as well as vertical loads. Delta Geo Drain Quattro has a very high load-bearing capacity (400Kn per meter squared).
