The following is a small selection of case studies to offer some insight into the more recently completed projects conducted by Advanced Preservations.

Langton Priory, Guildford - A beautiful residential development


Langton Priory is the stunning conversion of a charming historical priory into several luxury residential apartments conducted by Newcourt Residential. The Priory runs alongside the river Wey in Guildford and houses two basement apartments which were sympathetically designed to retain the layout and detail of the heritage property.  With internal finishing of the highest standard, ensuring the basement apartments remain dry and protected from sustained ground water flow was of utmost importance.  Working in a design and installation capacity, we detailed a Type C Cavity drain membrane system to provide reliable and ongoing protection.


Through good communication, setting clear goals and working closely with a reliable developer, this project is an ongoing success with a dedicated waterproofing solution designed and installed to achieve a habitable Grade 3 environment as identified in the British Standard BS8102.

The Dickson Poon China Centre, St Hugh's College, University of Oxford

willis projectThe magnificent Dickson Poon Building in the grounds of St Hugh’s College, is a prestigious, state of the art, multi-storey centre opened on 8 September 2014 by HRH The Duke of Cambridge.  The project comprised a large basement with a floor space of nearly 5,500 square metres to house a large part of the Bodleian Libraries’ Chinese book collection. The basement also features a 100-seat lecture theatre and ornamental central garden.

Due to the nature of the internal archive and high level finishes, providing a reliable waterproofing solution was of utmost importance.  Working closely with the Architect and Construction team, Advanced Preservations designed and installed a multi-line of defence waterproofing system, with Fosroc external Type A Barrier membranes, integral Type B concrete and a fail safe Newton membranes internal Type C Cavity drain membrane system with bespoke drainage arrangement.

Combining thoughtful and considered design with robust and methodical installation, made this challenging project a great success.

The Lalit Hotel, Tower Bridge, London


This 180-year-old beautiful London building, once housing the erstwhile St. Olave’s Grammar School has been recently re-modelled and unveiled as The LaLiT London.  Whilst converting this luxury boutique hotel, some of the ornate original roof timber trusses, one of the key features of the great dining hall, were found to be affected by timber decay to the bearing ends causing concern over structural stability.

3D-34177-TRSIn conjunction with the project engineers and a dedicated timber expert, Advanced Preservations designed a remedial scheme to produce a concealed, invisible repair to the structural hammer-beam, whilst maximising the retention of original listed timber sections.

Specially formulated Rotafix resin timber repair systems were implemented to return and improve the structural performance of the original beams, whilst remaining sympathetic and in sync with the needs of the construction team, the tight working environment and the desired finished product.
