Harrington Court

Harrington Court Structural Renovations

Structural Renovations Limited has recently completed phase one of the concrete repair, waterproofing and upgraded handrail works at the rear elevation of a 5 storey residential block close to central Croydon.

The works were secured after a sealed bid tender process and we mobilised on site in late August.

Following the erection of scaffold, the concrete was surveyed to identify the extent of defective concrete, which enabled concrete repairs to be carried out, using Fosroc repair products. A pigmented anti-carbonation coating, also by Fosroc was applied once the underside of the communal balcony slabs had been pressure washed. This not only affords additional protection from the elements but provides a uniform finish to both repaired and original concrete.

The top surfaces of the communal balcony slabs were then prepared to receive a fully reinforced, waterproof, polymethyl methacrylate (PMMA) resin system, produced by WestWood Liquid Technologies. The system was specified due to a number of factors: speed of application, durability and aesthetics, all of which were desired by the Client.
Additionally, as part of the refurbishment, we were instructed to upgrade the existing handrails, whereby additional security panels were affixed to close off large gaps between the horizontal rails, which were deemed unacceptable by today’s standards.

Further phases of work are planned for the building in the near future.

Emmanuel Church

Emmanuel Church Structural Renovations

Structural Renovations recently completed structural repairs and associated works to a 1950s church in southwest London.

This Anglican church which is part of the Diocese of Southwark was built to serve the expanding post war residential area of Morden and North Cheam and is constructed from brickwork with large reinforced concrete window frames, the latter of which, after 7 decades required extensive repair both internally and externally.

Following the installation of suitable protection scaffolding was carefully erected behind the alter within the church and externally at each end of the building to provide a safe means of accessing the working areas.

All concrete was inspected, with defects being marked up for removal following agreement with Church’s structural engineer. Once the defective concrete had been removed all exposed reinforcement was mechanically cleaned to remove any build-up of corrosion, before being fully protected with the specified materials (Fosroc Limited). The prepared defects had temporary formwork fixed prior to reinstatement to the original surface profile, using a hand placed polymer modified mortar. All internal concrete repairs were finished using a colour-matched mortar, so as not to be obvious to the congregation.

Once the repairing was complete, we replaced a number of previously damaged coloured glass panes, before preparing and redecorating all Crittal window frames. All external concrete was coated using a pigmented anti-carbonation coating. Previously coated woodwork was also repaired and redecorated.

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.
