Cadogan Place, Knightsbridge – screeds for prestigious development

Cadogan PlaceApproved Contractor CCS installed 600m2 of Ronacrete Ronafix screeds to a nine storey £180 million development in Cadogan Place, Knightsbridge.

Cadogan Place is described by estate agents as a “prestigious street moments from the many fashionable shops, bars and restaurants of Sloane Street”. The buildings are chiefly from the Regency period and many have been refurbished to high specifications. As part of a large refurbishment project CCS contractors laid Ronafix polymer modified screeds to several floors of the development. Ronafix Mix A1 and Ronafix Mix G were laid on underfloor heating systems and on acoustic matting.

Ronafix Mix A1 (also available as Ronafix Pre-packed Screed 25mm+) and Ronafix Mix G (also available as Ronafix Pre-packed Fine Concrete 25mm+) were mixed and pumped with a Putzmeister M760.  Ronafix Mix A1 is a thin bonded or unbonded polymer modified levelling screed which can be laid from any thickness greater than 25mm.  The Ronafix Mix G mix incorporates a 10mm pea shingle for added strength.

Ronafix Mix A1 is covered by BBA Certificate No. 89/2150 providing CCS and the client assurance of quality and performance of the screed in this high value project.

All Ronafix mix designs are also available as pre-packed products that offer the greatest possible assurance of screed quality and consistency. All Ronafix screeds provide; high strength, very low shrinkage and low permeability and some, like Ronafix Mix Designs A, B and B1 provide excellent wear resistance.

Access for all in Anglesey – RonaDeck Resin Bonded Surfacing

The development at Cemaes Bay is being undertaken as part of the County Council’s £6.9m Development of Anglesey’s Coastal Environment Project (2009 -15) which aims to develop on-shore and off-shore facilities to maximise economic benefits and impacts from the coastline of Anglesey.

The project

As part of the Development of Anglesey’s Coastal Environment Project MWT Civil Engineering were contracted to create an ‘access for all beach’. The work involved resurfacing the area, improving access to the beach and installing new street furniture.

RonaDeck Resin Bonded Surfacing was specified for the resurfaced areas with a 1-3mm Brittany Bronze aggregate. MWT Civil Engineering excavated the area prior to laying the asphalt base on which the resin bonded surfacing was applied.

The new beach access is likely to attract many visitors annually and because of its proximity to the sea will frequently become wet, it was therefore necessary for any paving used to be slip-resistant and durable.

Ronacrete’s RonaDeck Resin Bonded Surfacing is a hardwearing surfacing system composed of a resin base and natural aggregates that offers excellent slip-resistance tested to BS 8204-6:2008+A1:2010 Appendix B. It can withstand heavy footfall year after year and is used in a variety of projects with high visitor numbers, including the ramps at Wembley Stadium.

Product and application

RonaDeck Resin Bonded Surfacing is normally laid on concrete or asphalt as in this project. The asphalt’s surface was open textured so RonaDeck Resin Bonded Scratch Coat was applied by MWT producing a smooth substrate for the surfacing.

MWT mixed the two component resin with a drill and paddle mixer and applied it by roller to the substrate. The aggregate was immediately cast into the resin and left to cure for four hours. After removal of loose aggregate, the surfaced area was ready for use.

RonaDeck Resin Bonded Surfacing is DDA compliant, a requirement of an ‘access for all beach” providing a level surface that is slip resistant and wheelchair user friendly. RonaDeck Resin Bonded Surfacing is also suitable for vehicle traffic.

Wigan and Leigh Hospice

250 square metres of RonaDeck Resin Bound Surfacing was laid to the entrance and gardens of Wigan and Leigh Hospice using Harvest Crunch aggregate blend.

The Woodview Centre was added to the Wigan & Leigh Hospice in a £1.5 million building project which included a two storey building to house  the Hospice in Your Home service, consulting rooms and therapy clinics, it also involved landscaping a large area of grounds. Ellenby Construction began work at the site in April 2013. The client’s brief was to “build a modern eco-friendly development within a peaceful and therapeutic environment”.

IMG_1970 It is known that a green and leafy setting can benefit a person’s wellbeing and the landscaping was designed to provide a tranquil and relaxing outdoor environment that could be viewed and visited by patients and their visiting friends and family.

Pathways were installed through the existing woodland area and a new pond was installed, providing a natural link between the new Woodview Centre and the original hospice gardens and nature reserve.

Paths and the entrance to the new centre were surfaced with RonaDeck Resin Bound Surfacing, using a Harvest Crunch aggregate blend. RonaDeck Resin Bound Surfacing provides a slip-resistant surface for patients and carers to be able to enjoy the natural outdoor setting in safety.

IMG_1979RonaDeck Resin Bound Surfacing provides a strong, durable and porous pavement, which is particularly suitable for wheelchair ‘traffic’ as wheels will not sink and get caught as they can in loose gravel paths, the porosity of the system allows water to drain to the base and ensures that paths are free from standing water. This permeability makes the surfacing system SuDS compliant, which is in keeping with other sustainable aspects of the building project which include solar panels, under floor heating and the new pond which increases biodiversity in the area and is refreshed with recycled rainwater collected from the centre’s roof.

Ronacrete Approved Contractor Elite Surfacing mixed the two resin components with a slow speed drill and paddle before adding the resin to a large forced action mixer containing the aggregate blend. After ensuring that the aggregate was fully coated with resin, Elite Surfacing spread RonaDeck Resin Bound Surfacing to level at a depth of 15mm and smoothed the surface with a steel float.  The finished surface was ready for foot traffic within four hours.

The project was given a Royal seal of approval in June 2014, when Prince Edward officially opened the Woodview Centre. He was given a guided tour of the site which included a visit to the pond and the new landscaped areas via the resin bound pathways.

Outdoor space aids health and well being at iconic music site

logo black with black subtext + transparency155 square metres of RonaDeck Resin Bound Surfacing was applied to the internal courtyard of Queens Court, a new affordable housing block built on the site of the old Queen’s Hall, a once popular music venue in Widnes.

MONTAGE FinalREDThe housing scheme was designed for Halton Housing Trust by award winning Liverpool architects, Denovo Design. Forrest Construction was the main contractor for the project which comprised 17 apartments with car parking and associated landscaping.

The new affordable apartments were built on the site of the iconic Queen’s Hall music venue, which had hosted many bands including The Beatles, The Stone Roses and The Happy Mondays but was demolished in 2012 following a fire. Part of the brief for the design was to commemorate the site’s musical heritage, so the building includes a full height showcase art work commemorating some of the many acts that performed there and colourful ‘guitar string’ louvres make a bold statement above each of the designated entrances.

Case Study Queens Hall Feb 15The design for the new apartments needed to compensate for the lack of green space in the area and health and wellbeing was key to the design concept. All residents therefore have access to open space, with lounges having either an upper floor terrace; or a ‘Juliet balcony’. For ground floor residents an “outdoor space” was created in the form of a quiet, landscaped internal courtyard.

To create this outdoor space, flowering shrubs and semi-mature trees were planted around the inner courtyard to obscure the car parking bays and to provide a green outlook from the bedrooms. RonaDeck Resin Bound Surfacing Quartz Parallel aggregate mix was laid in a curved shape across the centre of the courtyard, providing a pale contrast to the surrounding greenery and red brick of the building.

Product and application

Ronacrete Approved Contractor Elite Surfac(  Queens Court (60))ing were sub-contracted to lay RonaDeck Resin Bound Surfacing across the 155 square metres of courtyard.

The RonaDeck Resin Bound Surfacing system was supplied as a two-component UV stable polyurethane resin and a blend of kiln-dried aggregates; the two resin components were mixed by Elite Surfacing with a slow speed drill and paddle before being added to a forced action mixer containing the Quartz Parallel aggregate blend. The RonaDeck Resin Bound Surfacing was spread to level before smoothing with a steel float.

RonaDeck Resin Bound Surfacing is a hard wearing, permeable (SuDS compliant) alternative to traditional paving and has the attractiveness of natural aggregate while being easily maintainable, unlike loose gravel. It is also suitable for wheel chairs and is slip-resistant. The resistance of the resin to ultra-violet light ensures that the resin will not yellow or darken over time, so the Quartz Parallel will retain its light appearance.

(  Queens Court (43))web2“RonaDeck Resin Bound Surfacing was specified because the Quartz Parallel aggregate mix contained a good selection of colour ways. The other important feature was that it suited the sinuous shape of the pathway unlike traditional paving, which would have necessitated a lot of cutting to shape and would have been more time-consuming and challenging to lay. The finished product in its inviting pale hue, looks immaculate and brightens up the enclosed courtyard.”

Frank Olchowski, Director, Denovo Design


RonaDeck Resin Bound Surfacing is an integral part of the outdoor space provided for the health and well being of the residents at Queen’s Court apartments. Denovo Design was very pleased with its performance and appearance and will be considering its use for future projects.

RonaBond four stages of concrete repair at St Saviours’ Estate

Repairs to six blocks of flats were carried out by Ronacrete Approved Contractor Gunite (Eastern) Ltd for Lengard on behalf of Southwark Council.  They used products from the Ronacrete RonaBond Concrete Repair & Coatings range as part of a larger refurbishment project costing around £4m.

Main contractor Lengard was awarded an internal and external refurbishment project by the London Borough of Southwark.  The refurbishment was carried out on six blocks of five, six and seven storey residential flats at St Saviours Estate, London SE1. The project required repairs to the fabric of the buildings.

Valios Staircase

Ronacrete Approved Contractor Gunite (Eastern) Ltd was sub-contracted by Lengard to carry out concrete repair and protective coatings, mastic joint sealing and brickwork repair.

Gunite cut out and prepared areas of damaged concrete, primed the exposed reinforcement with Ronacrete Standard Primer and then re-primed the reinforcement when the concrete was primed, before applying RonaBond HB40 high build polymer modified mortar.

RonaBond HB40 is a pre-packed high build polymer modified concrete repair mortar. It is often used to repair concrete on vertical surfaces and soffits where ease of application is as important as strength. It is typically applied in layers up to 50mm thick on walls on walls and 30mm thick on soffits.

RonaBond HB40 is particularly suited to the repair of overhead concrete, such as the underside of concrete staircases, which can become damaged over time, especially when exposed to the elements as the staircases are on the St Saviour’s estate.

St Vincent Rear East

The repaired areas were then made ready for decorative and protective coatings by the application of RonaBond Easy Skim FC. This is a pre-packed polymer modified mortar which is applied as a skim coat in thicknesses up to 3mm, to provide a smooth, hard finish to damaged, blemished and repaired concrete. It is a levelling mortar that provides a smooth “harder than plaster” finish to walls.

The final stage involved the application of decorative and protective coatings to the repaired surfaces. Two products were used at this stage, RonaBond Crack Bridging Anti-Carbonation Coating WB and RonaBond Anti-Carbonation Coating WB.

RonaBond Crack Bridging Anti-Carbonation Coating WB is a high build elastomeric, waterproof and carbonation-resistant façade coating based on water borne acrylsiloxane. It protects façades against water ingress while allowing diffusion of normal levels of background moisture vapour. It provides excellent protection against corrosion of the steel reinforcement when applied to reinforced concrete.  The siloxane component improves dirt shedding properties and protects against leaching of contamination through the coating.

RonaBond Anti-Carbonation Coating WB is a smooth, coloured, water borne acrylic anti-carbonation coating for use on vertical surfaces, soffits and at DPC level.  It allows the passage of moisture vapour so it is particularly suited for application to substrates which may contain entrapped moisture.  It can be applied to external walls and façades and protects against water, frost, and weathering it is also an effective barrier against the damaging effects of carbon dioxide gas. RonaBond Anti-Carbonation Coating WB is available in a wide range of colours, BS or RAL colours can be produced.

The RonaBond products used by Gunite provided a complete four stage concrete repair system at the St Saviour’s Estate project. Stage one, bonding agent (primer), stage two, polymer modified repair mortar (RonaBond HB40), stage three, levelling mortar (RonaBond Easy Skim FC) and stage four, protective and decorative coating (RonaBond Anti-carbonation Coating WB and RonaBond Crack Bridging Anti-carbonation Coating) greatly improving the integrity of the concrete and appearance of the flats on the St Saviour’s Estate, as well as providing protection from further corrosive damage for years to come.
