Following winning the tender for the full renovation of private apartments and building communal areas at Franklin Сourt at the heart of London, we presented the work schedule, method statements and CPP to our customer for approval.
The project included partial replacement of the apartment blocks’ roofs, replacement of the rainwater guttering, renovation of the corridors, staircases, and landings of the entire communal areas (i.e., complete communal area rewiring, installation of new LED lighting throughout the communal areas, and installation of the fire alarm systems). In addition, the project included a full renovation of all apartments in the Frankin Court buildings, including the installation of new kitchens, bathrooms, engineered wooden flooring, and full decoration throughout.
Also, as it emerged at a later stage, the building’s commercial sewers, drains and waste pipework had to be replaced.
The project phases relating to the renovation of apartments and corridors with the modernization of lighting were planned according to a clearly defined schedule, which was followed by agreeing on the list of works with the homeowners of each apartment in those multi-story buildings. The British Builders team had no concerns regarding the organising and planning of the above-mentioned projects, as we have sufficient experience with the execution of similar past projects.
However, during the roof survey, it was discovered there were problems with the roof storm drain systems. Furthermore, according to our roofer’s report, several downpipes were heavily blocked by vegetation mixed with gravel that had entered the gutters after heavy rains. In addition, they discovered damaged waterproofing and thermal insulation on the roof in the place where the flooring is made of concrete slabs. The renovation of the roof was required according to the type of inverted warm roof supplied by Bauder. We would have to consult with the Bauder merchant supplier to purchase all the necessary materials to ensure the quality of work according to specifications.
We began work on the roof by repairing/replacing the roof’s concrete slab area, supplying and Installing new Bitumen membrane insulated outlets, and damp-proof work on the roof. All work was carried out according to Bauder’s Specifications. Additionally, we replaced the roof’s guttering and downpipes.
After confirming that the roof is watertight, we began full communal area rewiring, replacing the LED lighting, emergency lighting, fire and smoke alarm systems, and installing H&S signage and posters as needed.
In accordance with the approved work schedule, inventory of works, and budget, we began the restoration of the apartments. New kitchens and bathrooms were supplied and fitted, and interior decoration and installation of engineered wood flooring in each apartment have been completed successfully. Two of our teams took turns working on this project segment to expedite the process.
Following this, our carpenters have laid down commercial heavy-duty vinyl flooring across all communal areas and landings.
British Builders team has completed this project under budget and 2 weeks sooner than planned thanks to careful planning, proper project management, experienced builders and the collaborative efforts of everyone involved.
Useful information: Inverted roof (upside down roof).
In an inverted roof construction, the principal thermal insulation layer is located not only above the roof structure but also above the waterproofing, resulting in the waterproofing, structural deck and support structure being at a temperature close to that of the interior of the building. No vapour control layer is required.
This type of flat roof is widely used on civic buildings, hotels, apartment blocks and hospitals. It is ideally suited to roofs which are heavily trafficked, such as car park decks, patios and roof gardens. The thermal insulation should have high resistance to water absorption, be dense enough to support the loads imposed upon it and have overlapping or interlocking joints to minimize thermal bridging.
To regulate the movement of water and protect against dirt and grit penetrating the joints between insulation boards, a water flow-reducing layer (WFRL) should be placed on the insulation layer; to assist the flow of water to drainage outlets.

GENERAL maintenance procedures and recommendations.
These practices should be carried out after any building maintenance, plant and equipment work on the roof, after major storms, or at six monthly intervals (ideally Spring & Autumn) as a minimum in accordance with BS 6229:2018 Chapter 7. All maintenance ensures the roof continues to perform, and that any potential problems are identified at an early stage. Regular routine maintenance should also be carried out where standing water exists to deter a build-up of algae or silt, which may in turn have a detrimental impact on the surface of the waterproofing, e.g. ‘mud curling’. Any failures of the roofing system resulting from a lack of maintenance may not be covered under the guarantee. Reference should also be made to the guarantee documents to identify if there are any further inspections that may be required to ensure the continuation of the guarantee period.
◼ Ensure safe access can be gained to the roof and that relevant Health and Safety procedure are followed.
◼ Sharp debris can damage the membrane so a visual inspection is advised. Remove all debris from the roof surface, outlets, chutes, gutters, inside inspection chambers or access grilles etc. Ensure water runs to and drains freely from downpipes/outlets. Debris must not be flushed down rainwater pipes.
◼ Cut back tree limbs that overhang the roof to give a 1-meter clearance outside the roof edge. This will significantly reduce the blockage of drainage ways due to fallen leaves.
◼ Remove any plant growth that may have occurred, taking care not to damage the waterproofing.
◼ Ensure protective metal flashings and termination bars remain securely fixed, repair or replace as necessary.
◼ Examine all mastic sealant and mortar pointing for signs of degradation, repair or replace as necessary.
◼ Check that all hard landscaping or proprietary surfacing finishes i.e. resin bound gravels, promenade tiles or paving slabs are securely fixed/adhered to the roof surface and in good condition.
◼ Ensure that any items of plant/equipment that may have been introduced to the roof are sited on a suitable slab or proprietary system, with additional compatible surface protection beneath, and that any fixings that may have been used to secure them, do not penetrate the waterproofing.
◼ Look for signs of contamination including leaks caused by plant equipment which might degrade the waterproofing. Follow the plant manufacturer’s maintenance procedures accordingly to rectify the issue.
◼ The Building owner should keep a record of all inspections and maintenance carried out on the roof. Any signs of damage, contamination or degradation should be reported to Installer/Producer immediately so that arrangements can be made for remedial work to be carried out if necessary.
◼ Any repairs to the waterproofing should be carried out by an Approved Roofing Contractor, ideally the original installing Roofing Contractor.
◼ When carrying out any maintenance to adjoining roof areas, care must be taken not to damage the landscaping or the waterproofing system. If it is considered that either element has been affected, then contact Bauder for advice. Any waterproofing damage caused after the completion of the original installation may invalidate the guarantee.
◼ Any unauthorized alterations to the waterproofing system will invalidate the guarantee. If such a situation should arise, then contact Bauder for advice on how the alteration can be incorporated without affecting the guarantee.
