Sika watertight concrete for development

Sika watertight concrete is being supplied to MJS Construction (March), on a prestigious new development currently being constructed in St Mary's Road, Market Harborough.

The project, which is being run by J H Hallam Contractors , is to be known as Millenium Mile and will include 219 luxury apartments built over a large underground car parking area.

Because of its close proximity to the River Welland and a high water table, keeping the car park dry was high on the list of priorities.

The preferred solution from JSandP Architecture was to use Sika watertight concrete for the podium slab and transfer deck, which offers structurally integral protection, with the benefit of substantial saving in construction time over traditional membrane systems.

The Sika Watertight Concrete system is based upon the use of two Sika admixtures: Sika Viscocrete 10 Superplasticiser, a powerful water reducing admixture and Sika 1+ which blocks the capillary pores and provides effective protection down to 10 bars or 100 metres head of water.

Sika Watertight Concrete has a long and successful track record and meets BS 8102 grade 3 protection for ventilated residential and working areas.

To ensure water tightness at both the horizontal and vertical joints, the Sikaswell jointing system is being employed.

Lafarge Readymix are supplying around 2,000 cubic metres of Watertight Concrete to the project, which is being developed by Paul Vesty Developments.
