Royal College of Surgeons Ireland

For over 200 years, the Royal College of Surgeons Ireland (RCSI), has played a major role in medical education and training in Ireland. Founded in 1784 to train surgeons, today the College provides extensive education and training in the healthcare professions at undergraduate and postgraduate level.
Henry J Lyons Architects in Dublin required a seamless floor for the RCSI campus refurbishment, which included the entrance, lobbies, stairway, and lecture rooms.
PanDOMO® TerrazzoPlus white was selected for this project, with 3-9mm white cararra marble added to create a stylish, fast track alternative to traditional terrazzo flooring.

Products used: ARDEX A 38, ARDEX K 15, PanDOMO® TerrazzoPlus

ARDEX WPC Now Available in White!

ARDEX WPC Flexible Rapid Drying Waterproof Protection Coating was first launched in the 1970s, and to this day is still a favourite amongst fixers due to its easy to apply formulation and rapid 90-minute tile-on-time.

It’s now available in a new White version which, due to its light colouring, allows fixers to see their setting out lines between the adhesive ribs, making tile placement easier and more accurate. It’s also ideal as a waterproof background for fixing light and translucent coloured mosaics.

Like its Grey counterpart, ARDEX WPC W creates a protective waterproof coating that stops moisture migrating from wet areas through to any adjoining rooms, and prevents any costly and unsightly water damage that could happen as a result. A recommendation under British Standards (BS 5385), any installation subject to frequent water contact should have the underlying substrate tanked; ARDEX WPC and ARDEX WPC W are the ideal solutions to ensure you’re working to these standards.

For more information, visit the ARDEX WPC page here or watch it in action in our video.

ARDEX WPC W is available to purchase now, and you can use our online stockist locator to find your local distributor.

The ARDEX Natural Stone Range

Eliminating the Risks of Water Staining, Curling and Warping in Natural Stone Installations

Natural and agglomerated stones such as granite, marble and limestone are naturally durable materials that can last a lifetime. However, like any product, problems may occur if they are not installed properly.

The main issue associated with natural stone is determining whether the stone is moisture sensitive or not and, following that, using the correct products to fix it. In most instances natural stone tiles will not have a sensitivity to moisture, and non-specialist products can be used with confidence; however, using such products to fix moisture sensitive stone can lead to permanent defects in the finished result.

Typically occurring during the bedding and grouting process, moisture from traditional adhesives and grouts can migrate into the stone and cause discolouration, staining and even warping.

For tile fixers using moisture sensitive natural stone or agglomerated stone, or for those who are unsure, ARDEX has developed a system of products specifically designed to eliminate these problems, helping to ensure a risk free installation every time.

ARDEX natural stone products incorporate our unique ‘RAPIDRY FORMULA’ technology and ‘lock’ the mix water within the mortar, virtually eliminating the risk of water staining, curling and warping.

Council House Refurbishment

In 2014 Wrexham council started a refurbishment program for all their council houses built in the 1960s. The existing subfloors were a mixture of quarry tiles or concrete, and following moisture testing, the R.H (Relative Humidity) readings were over 85%, which was probably the result of an absent or ineffective damp proof membrane.

ARDEX UK is a system solution provider of high-performance speciality building materials, and the brand choice for installers and distributors throughout the construction industry.

ARDEX products used on the project:

  • ARDITEX NA – Ultra Rapid Setting Subfloor Latex Levelling and Smoothing Compound
  • ARDEX DPM 1 C – One Coat Surface Damp Proof Membrane

Around 5,000 properties will be refurbished each year, with another three years to go on the project. ARDEX are working in partnership with Tarkett, using Safetred Spectrum Vinyl Flooring.

For The Perfect Floor You Need the perfect subfloor

Established in 2009, House to Home Furnishers, based in Stranraer, Wigtownshire, is a family run business offering a complete home furnishing service. Since opening, they have continually strived to bring their customers the best in quality home furnishings and fitting services, from new flooring installations, furniture and more, along with a customer service which is second to none.

House to Home Furnishers regularly install Luxury Vinyl Tile floorcoverings using ARDEX products, and Jamie Nelson, owner, commented “We have a great relationship with our local ARDEX Area Sales Manager, Morris Pate, who introduced us to ARDEX K 39 last year. Since then we always carry it in stock as one of our preferred levelling compounds.”

“ARDEX K 39 has amazing flow; it’s super smooth! Other levelling compounds leave joint marks and ridges, which usually means additional prep work and rubbing down the next day. ARDEX K 39 guarantees a perfect subfloor, and gives me peace of mind that, when I come back the next day, I’m ready to fit the floorcovering with no delays.”

In this particular installation, Jamie used the following ARDEX products:

  • ARDEX MVS 95 – One Component Residual Moisture Vapour Suppressant
  • ARDEX K 39 – Extended Workability, High Flow Levelling and Smoothing Compound
  • The hall and front porch were fitted with Neobo, Amber Glaze Parquet. The kitchen and dining area were fitted with Karndean Art Select Melbourne.

Tottenham Court Road Underground Station Refurbishment

Tottenham Court Road Underground Station opened as part of the Central London Railway (CLR) on 30th July 1900. Today, its location in the capital means it connects over 150,000 passengers daily; a figure that is expected to increase to over 200,000 when Cross Rail serves the station in 2018.

Throughout 2015 DMC Contracts Ltd, a main contractor for refurbishment works on London Underground, working alongside Taylor Woodrow BAM Nuttall (TWBN), used ARDEX products to complete the Central Line’s Tottenham Court Road Station upgrade.

Dave McCartney, Chief Executive of DMC Contracts Ltd commented “We have a long standing relationship with ARDEX UK, having worked for many years with their team, developing designs and completing a number of major projects across the UK to the satisfaction of our clients”

The design required DMC Contracts Ltd to complete a full wall and floor tiling installation that included the bespoke production of pre-cast skirtings and treads for the stairs and walkways, and breaking back to the existing substrate, making repairs using ARDEX Fast Track Repair Mortars and Screed Cements.

London Underground Ltd recommend the use of EXPAMET 267 Stainless Steel Rib Lath. The metal sheets provide a solid, secure background, and are ideal for use in the refurbishment of damaged, old and deteriorated walls; commonly found in the underground environment. ARDEX AM 100 Tile Render was applied to the Rib Lath, which were profiled to suit the natural curve of the walls. ARDEX AM 100 provided a smooth surface, which was ready for tiling in the shortest possible time, just two hours after application, meaning the area could be opened up to public access without additional hoarding.

ARDEX MICROTEC® X 78 was specified to fix the floor tiles because of its extremely high bond strength. Additionally, the semi-pourable consistency of the product helped the tile fixers quickly and easily achieve solid bed fixing, speeding up the installation process.

Due to the demanding environment of the underground, ARDEX MICROTEC® X 77 was specified on the walls. The adhesive is resistant to moisture ingress and has a high bond strength, meaning it can cope with both the vibrations from passing trains, and heavy trafficking of the passages and platforms.

The following products were specified for use in this project:

  • ARDEX A 38 – Ultra Rapid Drying Cement for Internal & External Screeds
  • ARDEX AM 100 – Rapid Hardening Tile Render
  • ARDEX A 46 – Multi-Purpose Repair Mortar
  • ARDEX MICROTEC® X 78 – Flexible Semi-Pourable Floor Tile Adhesive
  • ARDEX MICROTEC® X 77 – Flexible Wall & Floor Tile Adhesive
  • ARDEX FLEX FL – Rapid Setting Flexible Tile Grout

Paul Forrester, ARDEX Business Development Manager, commented “Since its opening the station has seen many modifications over the years, and this project has been the biggest yet. The main benefits ARDEX offered DMC Contracts Ltd were, not only the rapid drying times and strength of the finished products, but the technical and onsite support at every stage of the project.”

The ARDEX Guide to Tiling in Swimming Pools

Fixing tiles in swimming pools can present many challenges, but the choice of tiles combined with the correct preparation products, tile adhesives and grouts, allows you to not only create an aesthetically pleasing design, but one which is also durable and will withstand the most demanding conditions for years to come.

ARDEX products have been successfully specified in hundreds of swimming pools, from domestic projects to the London Aquatics Centre. In this article, we’ll take you through our top tips for tiling in swimming pools, and how you can get a long-lasting, durable finish.

Preparation, preparation, preparation

As with any project, preparation is key. The first step in any pool tiling installation is to evaluate the substrate and ensure it is flat enough to receive the tiles. According to British Standards, any deviations should not exceed 3mm when measured under a 2m straight edge. To be confident you’re starting with a flat, smooth surface, you should render the walls and screed the base.

This stage will also allow you to create ramps and falls if needed, and adjust the inside measurements of the pool to match the exact length and depth required; this is particularly important in commercial pools, which may need to be within a 3mm tolerance.

A problem we sometimes see at this stage is that the screed or render hasn’t been able to create an adequate bond to the substrate, which is usually caused by poor compaction of the product, or barrier materials on the substrate. Make sure you avoid this by shot-blasting to remove any loose, friable materials, and ensuring proper compaction of the screed or render.

Recommended ARDEX products:

  • ARDEX AM 100 Fast Track Tile Render: apply to walls 2-20mm thick and tile after 2 hours.
  • ARDEX A 38 Ultra Rapid Drying Cement for Internal & External Screeds: apply bonded screeds over concrete bases from 15-50mm and begin tiling after just 4 hours.
  • ARDEX S 21 Rapid Hardening Floor Tile Bedding Mortar: make ramps from 3mm to 15mm thick.

Waterproofing

Waterproofing is obviously very important in swimming pools; creating a watertight structure is a requirement of British Standards and prevents any leaks. It is essential that the waterproofing product is applied at the correct thickness, and that it covers the entire area, otherwise there could be leaks, which are notoriously hard to find after the full installation is complete.

It is also important to use the correct reinforcement tape beforehand, and this should be applied to all the joints between walls and floors, and any inlets to the pool.

Recommended ARDEX products:

  • ARDEX S 7 Flexible Waterproof Coating for Floors and Walls: apply 2 coats and install tiles 4 hours after the application of the second coat

Tile fixing

You’re now ready to fix the tiles, and in the first instance you must select an adhesive that’s suitable for use in swimming pools. Products such as ARDEX MICROTEC X 77 Flexible Wall and Floor Tile Adhesive, as used in the London Aquatics Centre for the 2012 Olympics, are not only compatible with these environments, but also provide a number of benefits for the fixer:

  • Fibre reinforced for enhanced adhesion and flexibility.
  • A 3 hour pot life and 60 minute open time allow more adhesive to be mixed and spread in a single batch, providing greater fixing efficiency over larger areas
  • Up to 19m² coverage from a single bag when fixing mosaics

Once you begin tiling, it is essential that solid bed fixing is achieved and that no voids are left beneath the tiles. Similarly, with mosaic tiles, ensure that no more than 25% of the back of the mosaic sheet is covered with glue or mesh; any more may prevent the tile adhesive creatimg an effective bond with the tile itself.

Grouting

The most common problem we see at this stage is where the incorrect type of grout is selected and inevitably degrades and/or falls out of the joints.

It is important to distinguish between the two main types of grout. Firstly, there are cement based grouts, which can be used in fully submerged areas and where the pool water is balanced. For areas of moving water, around the pool edge for example, or in outdoor or salt water pools, you should always look to use an epoxy/reaction resin grout. These grouts offer excellent chemical resistance and high standards of hygiene and cleanliness, but are considered difficult to use; opt for ARDEX EG 8 PLUS for the best of both worlds.

Recommended ARDEX products:

  • ARDEX-FLEX Tile Grouts: water repellent, dirt resistant and available in 32 colours. Select ARDEX-FLEX FS for joint widths up to 4mm wide and ARDEX-FLEX FL for joint widths 3-15mm wide and for a walk on time of just 90 minutes
  • ARDEX EG 8 Plus Epoxide Tile Grout: combines the chemical resistance of epoxy grouts with the ease of application of cement-based grouts. Requires no special tools and can be cleaned off the surface up to 45 minutes after application.
