Ronafix screed goes down swimmingly ready for Glasgow games


The Tollcross International Swimming Centre in Glasgow has been extensively refurbished in preparation for the Commonwealth Games 2014. The existing 50 metre pool has ten lanes and a new 50 metre six-lane warm-up and training pool has been added with new fitness suites, an extension of the changing rooms, improvements to the café, further seating and a general refurbishment of the existing facilities. These improvements will not only provide suitable facilities for the Games but also for future major international swimming competitions as well as providing an excellent permanent recreational and sporting facility for local residents. The project was funded by Glasgow City Council (£13.15 million) and sportscotland (£650,000), works commenced in May 2011 and the new centre was opened in May 2013.

As part of the redevelopment, the City of Glasgow Department of Architecture specified that the main contractors for the development, Barr Construction, should apply Ronafix Mix A to the stairways at the venue, to provide a hard wearing, dust proof, waterproof surface that could be laid in thin section. The screed was installed by sub contractor Industrial Floor Treatments

 

Ronafix Mix A is also available pre-packed as Ronafix Pre-packed Screed 6-50mm.  It has high compressive, tensile and flexural strength and can be trafficked after 24 hours; design compressive strength is 38N/mm² in 24 hours and70N/mm² after 28 days when cured at 200C.

 

Ronafix Pre-packed Screed 6-50mm comes from the Ronacrete Ronafix range of specialist quality controlled pre-mixed products. These include pre-packed products for tanking swimming pools and basements, for waterproofing structures, for under floor heating screeds and high-strength, thin and fast drying screeds.

EcoPath for Primary School Sensory Garden


Hobletts Manor Infant School required paths to be laid to their newly designed and created sensory garden, an enclosed area for children to enjoy nature and learn at the same time. The paths would be purely for foot traffic but needed to be visually attractive and slip-resistant. The school is committed to caring for the environment by recycling when possible, so Ronacrete’s newly introduced RonaDeck Eco Path MT was the obvious product for specification.

Eco friendly resin bound path.

RonaDeck EcoPath MT is a resin bound surfacing system that combines specially formulated resin with a blend of aggregate and recycled rubber granules (taken from truck tyres).

Ronacrete Approved Contractor Flintstone Solutions placed the vulcanised rubber granules (15kg) and kiln dried aggregate (75kg) into a clean, forced action mixer.

The two parts of the RonaDeck Eco Path MT resin were then mixed with a drill and helical paddle mixer attachment for 30-45 seconds. The mixed resin was immediately added to the mixer with the already mixed aggregate and rubber granules and mixed with the aggregate/rubber blend until the aggregate was evenly coated.

RonaDeck Eco Path MT was then applied at a thickness of 35mm to the prepared sub-base of compacted Type 3 aggregate and levelled and smoothed with a float, taking care not to compact the resin to ensure permeability.

The surface was allowed to cure and was ready for foot traffic within 24 hours. The day was sunny but if there had been heavy rain then the surface would have needed sheltering for the first 12 hours.

Concrete repair to Brighton art-deco appartment block


Repairs to the concrete façade of an art deco apartment block on Brighton sea front were carried out using RonaBond HB40 and RonaBond Flowable Micro Concrete.

Astra House is an Art Deco apartment block built in 1938 and situated on Kings Road on Brighton’s sea front.

The building houses commercial premises on the ground floor with 61 flats above. Decades of exposure to salt spray had corroded the reinforcement in pre-cast concrete façade panels causing spalling of concrete.  Despite several repairs over the years cracks continued to appear, eventually causing pieces of concrete to fall from the building.

Ronacrete Approved Contractor Constructive Solutions carried out a survey to establish what repairs were required and they were then contracted to remove the damaged concrete and debris from old repairs and to carry out the necessary repairs to the panels.  After removal and replacement of all reinforcement, RonaBond HB40 high build repair mortar was used to reinstate the concrete to the façade panels.  RonaBond Flowable Micro Concrete was used to re-form damaged sills.

RonaBond HB40 is a pre-packed high build, medium strength repair mortar for repairing concrete and protecting reinforcing steel. It is used to repair concrete facades and soffits, where its combination of ease of application and strength makes it an ideal product. RonaBond HB40 can be applied in thick-section layers up to 50-75mm on walls and 30-50mm on soffits, maximum layer thickness is dependent on the size of a repair.

RonaBond Flowable Micro Concrete is a repair concrete used in place of hand applied mortars to repair and replace sections of concrete. Designed for pour and pump application, the material is poured into shuttering to reform concrete profiles. It is shrinkage compensated and provides high early and ultimate strengths.

The residents were very pleased with the concrete repair work carried out by Constructive Solutions. It was part of a general refurbishment of the building which was overseen by Brighton and Hove Council and included interior and exterior refurbishment.

Ronafix – a new image but the same quality, strength and performance


Ronafix has long been established in the construction industry as a quality polymer
admixture; its reliability, performance and consistency making it a firm favourite with
clients, specifiers, contractors and distributors.

bottles overlap copyRonafix is the worldwide number one product specified for major and minor projects
throughout the world and has full BBA certification.

One thing that has changed about Ronafix is the appearance of the five litre bottle. As
part of a product rebrand, Ronafix five litre is now contained in a black bottle made from
recycled plastic. Each of the three applications has a different colour label; orange and
black for screeds, aqua blue and black for waterproofing and a vibrant red and black for
bonding and bedding

“We knew that Ronafix is a product renowned for its quality for over forty years,
but that wasn’t reflected in the packaging. People new to the industry could have
dismissed it as “just another admixture” if they weren’t aware of the Ronafix history
and reputation.”

The new branding makes the bottle stand-out amongst other similar products and
the metallic effect makes the labels shine, reflecting the quality of the, four times
BBA accredited, admixture they describe.”

Daniel Osen, Managing Director

Ronafix is the only SBR additive with four BBA certificates.

1 Ronafix BBA Approved admixture for screeds
British Board of Agrément – Certificate No. 89/2150

2 Ronafix Admixture for waterproof renders and tanking
British Board of Agrément—Certificate No. 86/1651

3 Ronafix BBA certified liquid admixture for concrete repair mortars
British Board of Agrément Certificate No. 89/2151

4 Ronafix Liquid admixture for bedding brick slips, paving & cladding
British Board of Agrément Certificate No. 89/2149

RonaDeck Resin Bound Surfacing at new Cumbrian hospital


A new community hospital was opened in Cockermouth in January 2014, this replaced the 100 year old building which had been hit by severe flooding in 2009 and GP services had to operate from temporary buildings.

The new community hospital houses Castlegate and Derwent GP surgeries, a pharmacy, a physiotherapy department and an in-patient ward.

Ronacrete Approved Contractor Route One Highways was appointed to lay 880 square metres of RonaDeck Resin Bound Surfacing to the paths leading up to the hospital entrance and those providing access to the landscaped gardens. The aggregate blend Choc Chip Harvest was chosen for this project, this blend includes a wide variety of aggregate shades.

The RonaDeck Resin Bound Surfacing System was supplied as a two-component UV stable polyurethane resin; the two components were mixed with a slow speed drill and paddle before being added to a forced action mixer containing the aggregate blend. The RonaDeck Resin Bound Surfacing was spread to level at a depth of 15mm by Route One Highways and the surface was smoothed with a steel float.

RonaDeck Resin Bound Surfacing is suitable for wheel chairs and is slip-resistant; it also complies with SuDS (Sustainable Drainage Systems) requirements. The porous surface allows rainwater to quickly and easily drain through into the earth beneath if it is part of a SuDS compliant system. By reducing the rate of rainwater run off SuDS can reduce the risk of overall flooding. A SUDS system is particularly beneficial during extreme weather when conventional drains cannot keep up with the water flow.

Ronacrete concrete repair products used in restoration of Hatfield health clinic


RonaBond HB40 and RonaBond Crack Bridging Anti-Carbonation Coating WB have been used in an NHS refurbishment project of a Hatfield health clinic costing just under £1million. Working for main contracting firm Newland Construction, Ronacrete Approved Contractor Apolodor carried out concrete repair and restoration work to the 1960s building which housed Queensway Health Clinic.

The project was a complete remodelling and refurbishment to meet the requirements of modern clinical standards, providing better facilities and easier access for patients and staff. Changes included a layout change to create easier access, new hospital-grade flooring and versatile multi-purpose treatment rooms. Improvements have also been made to the building’s energy efficiency with the introduction of solar panels, double glazing, insulation and a modern heating system.

Products from the Ronacrete Concrete Repair & Coatings range were used to carry out repairs and provide protection to stairways and roof areas.

Sections of the roof slab were repaired where corrosion of reinforcement had caused spalling of the concrete. Apolodor broke out the damaged concrete, treated the exposed steel with Ronacrete Standard Primer and then re-primed the steel and primed the concrete before repairing with RonaBond HB40. The same treatment was applied to concrete surrounding the downpipes.

Apolodor used the same repair technique on the staircase using RonaBond HB40, the underside of the staircase was then jet washed before the application of white RonaBond Crack Bridging Anti-Carbonation Coating WB.

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

 

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 facades 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.
