2 Sustainable damp proof membrance 100% recycled Sustainability in the Construction Sector There is growing awareness of sustainability within the construction industry. Not only has it become the main focus of government policy in the construction sector (under the banner of Sustainable Communities), but it is increasingly on clients agendas as a result of being asked to explain their approach to sustainability by investors, employees or suppliers. Specifying Recycled Products Specifying recycled products, in particular those exclusively manufactured from 100% post use waste, keeps reusable material in the economy, diverts waste from landfill and conserves resources. Plastics consumption is growing about 4% every year in Western Europe. In the UK it is estimated that plastics account for 7% of Household Waste of which 1.2 million tonnes are believed to be recoverable. Every year an estimated 17 billion plastic bags are given away by supermarkets which is equivalent to over 290 bags for every person in the UK.* The construction sector alone is estimated to consume almost 1 million tons of plastic each year so increasing the usage of recycled products has an enormous impact on the environment. Independent studies on the production of products made from recycled rather than virgin polythene show that the use of recycled plastic results in the following environmental benefits: Reduction of energy consumption by two-thirds. Production of only a third of the sulphur dioxide and half of the nitrous oxide. Reduction of water usage by nearly 90%. Reduction of carbon dioxide generation by two-and-a half times. It is estimated that 1.8 tonnes of oil are saved for every tonne of recycled polythene produced.** We live in an increasingly throw-away society and households are the biggest source of plastic waste, nearly 80% of which is landfilled. By specifying 100% post use recycled products the recycling loop is closed through the creation of demand for the materials recovered by recycling collection schemes. The Largest Polyethylene Recycler in Europe Visqueen Building Products, part of bpi plc Recycled Products Division, have an enviable reputation as the leader in the field of polyethylene recycling. Each year we recycle approximately 70,000 tonnes of low density polyethylene across our Environment Agency Accredited sites. Operate an ISO Accredited Environmental Management System Our business processes are accredited to ISO 14001, the internationally recognised standard for Environmental Management Systems (EMS). Sustainable Product Development Many of our damp proof membranes (DPM) and damp proof courses (DPC) products already contain a significant proportion of reprocessed and recycled polyethylene. Our product development strategy has been to introduce new products with strong environmental credentials. Visqueen Zedex CPT High Performance DPC minimises material usage without compromising performance, by using one-third less material than competing high performance damp proof course s. Visqueen Gas Protection Membranes assist in the safe economic development of contaminated brownfield sites. Plaswood an award winning range of wood replacement products manufactured from 100% recycled polyethylene for use as boardwalks, bollards, signage and street furniture. Specifying Recycled All of our literature is available electronically and in print format we only use 100% recycled paper of which 80% is classified as post use.

7 t DAMP PROOF MEMBRANE i f i c a t i o n C e r L i m i Installation guideines Visqueen EcoMembrane DPM must be installed in accordance with BRE Certificate No.112/04 and the following guidelines. Preparation for laying the membrane Even though Visqueen EcoMembrane has a high puncture resistance to normal foot and site traffic, care should be taken to avoid accidental damage on site. Similarly, where the base is uneven, a blinding of soft sand of a thickness that will cover all sharp projections should be used to avoid damage to the membrane when it is being installed, and when the concrete or screed is being laid. Jointing the EcoMembrane Adjacent sheets of the membrane should be overlapped by at least 150mm and sealed using Visqueen Double Sided Jointing Tape. The joint should then be secured using 100mm wide Visqueen Girth Jointing Tape. The membrane should be clean and dry at the time of jointing. Maintaining continuity It is essential that the Visqueen EcoMembrane is continuous with the DPC in the surrounding walls. Where the DPM is not at the same level as the DPC, the DPM should be taken vertically and connected to the DPC so that damp proofing is continuous. The DPM should also be continuous with any DPCs to internal walls. Special care must be taken to ensure continuity at corners. To help achieve this, special pre-formed wall/slab corner units are available from Visqueen Building Products. All laps must be sealed using Visqueen Double Sided Jointing Tape and Visqueen Girth Jointing Tape. Punctures Any tears or punctures in the membrane should be patched using a piece of the same material sized to overlap at least 150mm beyond the extent of the puncture, the lap being sealed with Visqueen Double Sided Jointing Tape and Visqueen Girth Jointing Tape. Service pipe penetrations Any penetrations for service pipes should be sealed using Visqueen Top Hat Units. The base of the Visqueen Top Hat Units should be sealed using Visqueen Double Sided Jointing Tape and Visqueen Girth Jointing Tape. REQUIRED COMPONENTS VISQUEEN ZEDEX DPC TECHNICAL DATASHEETS TYPICAL INSTALLATION CAD DETAILS NBS PLUS CLAUSES CPD TRAINING SEMINARS Covering Visqueen EcoMembrane should be covered by a protective layer (such as a screed) as soon as possible after installation. The membrane should be sufficiently loosely laid against upstands to ensure that the membrane is not stretched or displaced when applying the screed or concrete. A minimum thickness of 50mm screed is recommended. When reinforced concrete is to be laid over the membrane, the wire reinforcements or spacers must be prevented from contacting the membrane. It is recommended that the membrane be covered with Visqueen Protection Board or 50mm screed prior to placing the reinforcements. When underfloor heating is to be installed, Visqueen recommend that the barrier is positioned between the blinded hardcore and the insulation to protect the installation from moisture and to avoid any risk of overheating the membrane.

Side laps should be a minimum of 100mm and end laps must be a minimum of 150mm and the work should be set out with staggered laps between first and second layers. Ensure that a constant flow of bitumen is maintained across the whole width of the roll and that a bead of bitumen is extruded from each edge which demonstrates that a good seal has been obtained. On vertical areas, the membrane should be cut to the appropriate length, bonded to the horizontally applied membrane and torch applied upwards. On external applications Visqueen Protection Boards should be used.
