Summary

RASCOR is proud to contribute to the transformation of the existing building at Creed Court now known as ‘The Lost Property’. The hotel is located facing Ludgate Hill – leading up to St. Paul’s Cathedral which have narrow one-way streets. The construction consisted of several basements level and 6-storey above ground. The works included excavation of double level basement and a redevelopment of the office building into a 145 bed hotel which will include a bar & restaurant , gym facilities and internal courtyard

The Project

In order to deliver a reliable, watertight solution for this project, RASCOR worked closely with McAleer & Rushe to provide a complete design,supply and installation in the double basement. To achieve a Grade 3 basement / sub basement, required two types of waterproofing RASCOR used its RASCOtank Type B – structurally integral protection and Type C – drained protection.

The Process

For this project, we tasked our design team to come with the best waterproofing strategy to protect this prestigious structure from water ingress.

In this project ,we encountered a high water table level and significant temporary works.

Secant piles were installed around the perimeter of the site between the existing piles. The new sub basement and lower ground floor were constructed inside the piled walls on all sides lined with a water-excluding RASCOtank external type B system and propped at the ground floor and basement levels by the reinforced concrete construction.
The Primary solution for waterproofing this structure was the RASCOtank system which are cast and set during concreting to control crack shrinkage and subsequent injected with acrylic grout which will guarantee prevention of any water ingress from entering the structure.

The Solution

Our secondary line of defense provided for our Grade 3 area was achieved by using the Newton CDM System cavity drain membrane waterproofing, which will capture, depressurize and remove any ingress ground water via a series of Trojan-Pro pump.
The same two products were also used alongside the flexible 107F liquid membrane and 106 FlexProof for construction on joint waterproofing in areas where the existing brick structure interfaces with a new concrete slab. Finally, Titan-Pro pump chambers are being installed to remove the water.

Final Result

Completion date for the Hotel is Spring 2022 with RASCOtank waterproofing installation finalized early 2021 to bespoke specification.
