Highlight House

Structural Renovations Highlight House

As part of our ongoing relationship with the Langham Estate, we have been successful in securing works to another building within their property portfolio.

Highlight house which was constructed in the early 20th century comprises of retail at ground/basement level and office space on the upper floors.

Our works are concerned with the basement only, where extensive waterproofing is required to all retaining walls and soffits/underside of pavements.

A number of repair details have been devised for this project, as the construction varies throughout and therefore requires differing treatments to prevent the future ingress of water.

Working closely with the structural engineer (RKK Engineering) and Flexcrete Technologies Limited we have been able to satisfy the requirements of the client, who ultimately wishes to let the area as a restaurant or similar usage.

All existing render has been removed to expose brickwork beneath. The brickwork needed to be scabbled to provide a key for the specialist waterproofing materials. At all changes of direction, such a junctions between walls and soffits a reinforcing membrane was installed within a 2 part modified cementitious slurry prior to full embedment within the modified render.

This 10 week project is now nearing its completion allowing for the fit out to be completed by others.

Collingham Gardens

Structural Renovations - Collingham Gardens

Refurbishment works were recently completed to a former house that now operates as serviced apartments in the Brompton area of London. The property which was originally constructed in the late 19th century and was converted a number of years ago to its current use.

The front and rear elevations had not been maintained for at least 20 years and therefore required extensive repairs and redecoration, including brickwork/pointing works, waterproofing to balcony areas, timber repair/replacement and redecoration to all previously painted timber and stonework.

The front elevation was accessed from traditional scaffolding but due to a lack of access to the rear elevation this area was completed by means of abseil.

Specialist products supplied by both Fosroc (stonework repairs and stone coatings) and Sika Parex (brickwork/pointing repairs) were used throughout the works.

The project was completed within the anticipated programme regardless of the poor weather that was experienced during the works.

Portland House

We are nearing completion of a large water-proofing project within the basement of a former restaurant .

The works at Great Portland Street, in the West End of London involve the removal of all existing failed waterproofing to the internal faces of the brickwork retaining walls and soffits, followed by the application of a polymer modified cementitious waterproof render. The works also require us to reinforce all junctions of walls and floors, to accommodate any future movement at these weak points. All structural steelwork has also been prepared and treated with a cementitious epoxy coating.

The works have been carefully planned around the replacement of the original pavement lights and smoke vents, which have been allowing water to enter the basement over a number of years, leading to significant damage in the sub-terranean areas of the building.

This waterproofing scheme is one of a number of projects that Structural Renovations Limited have completed for the Langham Estate, who own and manage a substantial amount of property in the area.

Middle Walk, Woking

Middle Walk Woking Concrete Repairs Structural Renovations Limited

Structural Renovations Limited have recently completed extensive repairs to the exposed reinforced concrete elements of a 1970s residential development above retail units in the centre of Woking. The complex is currently undergoing a major refurbishment as part of the wider and ongoing transformation of the town.

The multiple working areas were accessed by various means, including fixed scaffold, lightweight aluminium mobile towers and mobile elevated work platforms.

The works involved surveying the concrete to establish the extent of defects, prior to breaking out and square cutting the hollow, cracked and spalling areas, preparing and protecting all mild steel reinforcement and reinstating with a polymer modified high build repair mortar.

All repairs were completed using products manufactured by Fosroc Limited, who we have been approved by for many years.

Immediately following the completion of our repairs, a support framework for a ‘living wall’ was fixed to the concrete prior to being filled with thousands of plants, purifying the air by converting carbon dioxide to oxygen, reducing noise and providing a more aesthetically pleasing environment.

Isleden House

Structural Renovations Isleden House

Structural Renovations Limited are currently working to repair and waterproof canopies at a sheltered housing complex known as Isleden House in Islington.

The estate was built in 1948 and opened by Queen Mary the following year. In 1953 the estate was handed over to the City of London who have instructed these works.

Following an initial condition survey concrete repairs have been completed using proprietary repair products, followed by the application of a pigmented anti-carbonation coating, which will extend the life of both repaired and unrepaired concrete.

The top surface of the canopies have been prepared and subsequently treated using a glass fibre reinforced polyurethane waterproof membrane to further protect the concrete.

The above works form part of a larger scheme that we have been asked to assist the City of London, which will involve us returning to the estate in 2021.

The White House, Grayswood

The White House - Structural Renovations

Structural Renovations Limited have recently completed the first phase of concrete repair and specialist coatings to a large residential property in Surrey, known as The White House.

The house, designed by the eminent architect, Amyas Connell in 1930 was completed in 1932, in the Modern Movement style and was Grade II* listed in 1971.

Built using reinforced concrete, with flat roof it was last renovated externally in the 1990s and was showing extensive signs of deterioration to both the concrete and the coatings.

Following an initial diagnostic survey it was possible to establish the type and extent of works required to reinstate the structural integrity of the structure, where required and propose a suitable scheme for the subsequent overall protection of the building, whilst satisfying the requirements, of all interested parties, including English Heritage.

We assisted in the production of an approved specification, using Flexcrete technologies repair and coating products and mobilised on site in early September.

All externally listed elements of the house were pressured washed and hand scraped to remove loosely adhered coatings, followed by a full hammer test to identify all areas of hollow/spalling concrete. Where required concrete was broken out, square-cut and all exposed reinforcement prepared and treated, prior to reinstated with a polymer-modified repair mortar. The entire prepared surfaces then received an application of an elastomeric levelling compound prior to two coats of white flexible anti-carbonation paint. All specified products were water-based.

The project was carried out from fixed scaffold and all works were completed whilst the client was in residence.

We will return for a second phase of works in 2021, when all listed elements of the property unconnected with the house itself will be treated using the same specification.
