St Pancras Station

St Pancras Station

Project brief

Limelite Heritage Mortars and Grouts to help restore St Pancras station buildings to their Victorian splendour.

The Project

Mortars and Grouts from Tarmac Building Products, the leading manufacturer of blended cementitious products in the UK, have been extensively used in the historic conservation of St Pancras station.

The major redevelopment of St Pancras includes the enlargement and refurbishment of the ticket hall, restoration of St Pancras Chambers as well as new passages to the existing Tube ticket Hall and Channel Tunnel Rail Link. PAYE Stonework and Restoration, a leading conservation specialist turned to Pozament for its expertise in pre-blended products formulated specifically for historic conservation work.

A hydraulic lime-based combination of materials that offers sympathetic controlled strength was blended by the team to meet the specific requirements of PAYE Stonework and Restoration.

Help from Tarmac Building Products – Limelite Heritage Mortars & Grouts

Around eight tonnes of lime based, cement-free materials including Heritage Mortar 4 and Heritage Grout 7 were supplied to point the brickwork joints of passages to the existing tube ticket hall and Channel Tunnel Rail Link and to repair sofits in the Grade I listed St Pancras Chambers.

Problems faced

St. Pancras Station is a Grade I listed building, meaning it is a building of exceptional interest and is one of the best Victorian buildings in central London. It has been voted one of London’s favourite landmarks and so great care had to be taken with the restoration work.


The extensive redevelopment of St Pancras and Kings Cross Underground was completed by the end of 2007.


Gary Hodges, project manager, PAYE Stonework and Restoration said, the range of pre-blended heritage grouts and mortars were ideal for this restoration project. Heritage Mortar 4 was highly suitable for the St Pancras Chambers repairs, reaching maximum strength within 7 days rather than the usual 90 days for other materials.

Stuart Allerton, Quality & Technical Services Manager, Tarmac Building Products said, The Limelite Heritage range has specifically been designed to be sympathetic with historic buildings and caters for a number of applications. Our re-pointing mortars and free-flowing grouts are manufactured at our Swadlincote facility in Derbyshire to order, typically within five working days.
