Main Products & Applications:
Delta provides waterproofing products for all three types of waterproofing (Types A, B & C) as defined within BS 8102:2009.
Our ‘Type C’ Waterproofing Systems are a maintainable basement/below ground waterproofing solution for new-build basements, refurbishment and retrofit projects. The Type C System comprises of a Cavity Drain Membrane, Drainage system, Package Pump and Control System.
In principle a cavity drain membrane system allows moisture or running water to travel behind the membrane within a controlled drainage system. A cavity drain system requires minimal preparation and disturbance to an existing substrate.
In various formats podium decks have been around for many years, however they are becoming more widely used on top of basement constructions as either paved areas, gardens or terraces. A podium deck is a structural element which is essentially an elevated platform which allows for usage both above and below, these may be terraces over underground car parks, gardens over basements, balconies over terraces and patios.
External Drainage Systems are also known as external tanking, which is the application of a waterproof membrane to the outside of a basement or substructure in accordance with BS 8102:2009 (Type A).
Delta Membrane Systems Limited offer a comprehensive range of ground gas protection solutions along with its structural waterproofing solutions. From our MemTech ground gas membranes to waterproofing systems, our product range is designed to deal with all ground gas, contaminants and waterproofing related problems.
Koster Bauchemie AG specialises in high quality structural waterproofing products and systems. These systems protect and preserve buildings and structures worldwide. Whether the subject is restoration of a heritage building, waterproofing of a new building, reinstalling failed horizontal barriers in masonry, restoration of wet basements, or waterproofing of roofs and facades, rest assured; with our comprehensive and deep product program Koster have the optimum solution.
Koster systems and products stand out due to their exceptionally easy and user-friendly application.
Specialist Basement Drainage – Pumps and Flood Protection
We have a team of application engineers who can assist with selection of ground, surface & foul water pump stations. This can be carried out against drawings, meetings on site & your offices or ‘via net’ viewer sessions.
We can also provide solutions for Flood prevention for both renovation and new build projects.
Damp Proofing – Above ground
Damp Proofing is the process in which methods are used to prevent water/water vapour from travelling through walls and floors from ground level up (rising damp). There are other ways damp can enter walls, but this is the most common.
Delta offer a range of physical and chemical DPC’s that can treat all types of Damp.
Structural Waterproofing – Pre-formed, Liquid Applied & Injection
Delta offer a wide range of waterproofing solutions for all types of applications. Products include pre-formed membranes & ancillary products, liquid applied systems, movement and construction joint waterproofing and injection systems. Please contact our technical team for support in selecting the right system for your project.

Delta Membrane - What is Radon and how can we protect our homes?
Radon occurs naturally in the environment. Radon gas is created when natural radioactive uranium slowly decays and can be found in all rocks and soils.
Radon can be found everywhere in the United Kingdom, although certain parts of the UK will have higher concentration levels than others. To check whether you are in a high Radon concentrated area visit https://www.ukradon.org/information/ukmaps.
This radioactive gas is, colourless, odourless and tasteless.
Radon is measured in becquerels per cubic metre of air (Bq m-3) and specialist equipment is required to detect it.
The average level of Radon in UK homes is 20 Bq m-3. For levels below 100 Bq m-3, individual risk remains relatively low and not a cause for concern. However, the risk to health increases as radon levels increase.
Radon can migrate into any building that is built over a source.
If Radon accumulates in a building, it increases the risk of lung cancer for occupants. Radon is the cause of 15% of lung cancers worldwide (World Health Organisation ‘WHO’ 2009) and the main cause of lung cancer in non-smokers and is responsible for over 1100 deaths in the UK every year.
Research published earlier this year has found that radon levels are increasing in buildings and homes due to the changes we are making to building efficiencies (such as energy efficiency). This in turn will lead to an increase in the number of lung cancer deaths attributable to radon exposure.
Technical solutions such as Ground Gas Protection Membranes incorporated into the design of buildings and structures can offer protection to occupants of homes built on contaminated lands and the harmful effects of radon.
Ground Gas Protection Systems can be used on new, retrofit and refurbishment construction although design considerations are more complex on retrofitted projects.
Forward thinking manufacturers, such as Delta Membrane Systems Limited, have sought to test all our products on their safety, reliability, high-quality and gas permeability.
Manufacturing flexibility has never been as important for the construction industry as it is today. The permeability of gas through a membrane is a critical factor when it concerns the ability of the lifetime of a building or structure.
Through extensive research we can state all our Cavity Drain Membrane Systems (CDMs) offer radon protection with a low permeability rate.
Whilst, our MemTech range of Ground Gas Protection Membranes offer complete protection from Radon, Hydrocarbons, Methane, Carbon Dioxide and Volatile Organic Compounds (VOCs).
Delta attend GE ‘Basements Conference’ 2019
Delta’s Director and Chair of the Basement Information Centre’s Marketing and Technical Committee, Kevin Dodds was delighted to attend this year’s Ground Engineering’s 12th Basements and Underground Structures Conference held on 3 October 2019 at the Olympia Conference Centre, London.
Delta were also delighted to collaborate in exhibiting with the Basement Information Centre, which offered a day of engaging with delegates.
The GE Basements and Underground Structures Conference aim was to explore the design and delivery of underground spaces whilst bringing together those working on a diverse range of projects in a cross-discipline of sectors.
From infrastructure, structural engineering, commercial to residential sectors, the event offered expert knowledge, best practice and networking opportunities for designers, contractors and manufacturers alike and a platform to learn, share and develop ideas to improve quality levels within our sector.
Focus was not only on selecting building materials which should fulfil the functions expected from them, with key to reliable construction being:
Technologies (how is technology influencing basement design and our capabilities)
Building materials used
But also, for the various sectors to work in collaboration and offering the end client value.
The focus on collaboration in general and partnership, has broadened and deepened to take root in most aspects of successful building design and delivery. Working in collaboration serves as a vehicle in the design processes and redefines best practice. By working in collaboration, the standard of workmanship can be improved by providing appropriate instructions, clear checklists as well as ensuring there is on-site guidance, supervision and monitoring and an ongoing process of feedback to ensure continuous improvement.
Presentations on ‘What does the future of the main contractor-led model’ look like and will specialists continue to lead on more basement projects were keenly addressed, along with case study reviews and technical and geotechnical presentations.
