Selecting products that are simple and quick to install, have non-slip properties, and are hard-wearing can have a tremendous impact


In terms of safety, an important feature of PMMA is that it does not need to be a torch-on solution. Tis makes it perfect for environments where torch-on techniques cannot be used due to fire safety requirements. As an alternative to PMMA-based waterproofing products, bitumen


membranes can also offer a solution that provides quality, durability and a strong service life, especially for flat roofs. For environments such as balconies, additional work will be required, in the


form of either adding a walkway or placing balcony tiles on top of waterproofing systems. Furthermore, in high-traffic areas, bituminous waterproofing may be more prone to damage, which is another important consideration. Ultimately, local authorities and social landlords need to have confidence


that the chosen solution is fit-for-purpose and can deliver the required upgrade efficiently and to a high-standard. Te best way to select the most appropriate solution is by partnering with an expert supplier who can provide the necessary guidance and product specifications.

Belfast transport hub features Magply A1 fi re resistant roof build-up


One of the most notable infrastructure projects to be completed in Northern Ireland over recent years is nearing completion with the specialist roofi ng contractor involved installing a PVC system across an intermediate level deck, where originally marine grade plywood had been specifi ed for the deck, but Thornton Roofi ng changed this to achieve A1 fi re performance by recommending A1 non-combustible Magply boards from the range of IPP Ltd, thereby complying with the province’s fi re regulations and mirroring those in the rest of the UK. With a Class 1 fi re rating and backed by BBA Agrement certifi cation, Magply MOS boards present a fi re-safe and environmentally friendly alternative to conventional plywood or OSB products. Additionally, the unique production process enhances both the boards’ stability and long-term durability, while they create an ideal substrate for installing the full spectrum of waterproofi ng systems. This includes their use in recovery applications and as a temporary protection layer. The different thicknesses of panel are also widely used as a substrate board for the direct application of proprietary render systems, as well as for fl ooring and pitched roof build-ups.

Crystal Damp Proofing & Basements is working close to its base in Croydon, Surrey while also employing a selection of products from the Wykamol-Triton range with which it is fully familiar. And while the company has undertaken many larger scale projects across the South-East since it was set up three years ago, the 40-year-old residential property its team is currently making progress on, is unusual in featuring existing basement areas both beneath the house and to the rear. The curved outside lightwell and the main sub-structure had both suffered long-term problems with damp and are receiving similar treatments in the form of the C20 and CM8 studded drainage membranes, installed across the concrete floor slabs and blockwork walls respectively: offering a permanent remedy to penetrating damp. Any water which does seep through the masonry is directed into perimeter drains formed using lengths of Aquachannel, which connect to a sump and one of the manufacturer’s Aqua Pump kits with battery back-up. The BBA approved Wykamol-Triton CM8 and CM20 Waterproofing Membranes – manufactured from high density polyethylene – are routinely specified as an extra layer of protection for the walls and floors of cellars and basements, with their studded form allowing any water to be directed into perimeter channels and then a sump, which is automatically emptied by an electric pump.
