Delta’s Directors attend The Worshipful Company of Constructors Installation Dinner

October 2018

Delta’s Directors, Christopher Burbridge, David Symes and Kevin Dodds were delighted to attend The Worshipful Company of Constructors Installation Dinner on Wednesday 10th October 2018.

Mike Parrett MSt (Cantab) CSCI CBuildE FRICS FCIOB FCABE FIMMM was formally installed as the new Master at beautiful church service held at the Guild Church of St Lawrence Jewry in Guildhall Yard. The evening followed by an installation dinner which was enjoyed by all.

Mike is a world-renowned expert in building pathology and specialises in dampness in buildings, including flooding, condensation and mould.

Christopher Burbridge commented “I have known Mike for many years, he has always been great company and is an incredibly gifted man and is well respected within the structural waterproofing sector. It was an honour to attend such a wonderful event. I wish Mike all the best in his new role”.

Drapers HallWhat is a Livery Company?

The City of London Livery Companies comprises of London’s modern and ancient trade associations and guilds, believed to have been formed around 1066. Almost all of London’s Livery Companies are styled as “The Worshipful Company of” followed by their respective trade/profession/craft.

Modern day Livery Companies celebrate and maintain contacts with their original trades. There are currently 110 Livery Companies in the City of London.

The qualification “City and Guilds” stems originally from qualifications supported by Livery Companies.

Who are the Worshipful Company of Livery Company?

The Worshipful Company of Constructors is a modern City of London Livery Company for professionals working within the construction industry. The Company was granted Livery by The Court of Aldermen in 1990, followed by a Royal Charter of Incorporation by Her Majesty, Queen Elizabeth II in 2010.

Many of the Liverymen are Chartered members of their respective professional institutions – some in leading positions. They come from all sectors of the construction trade, including architects, surveyors, engineers, builders, lawyers and accountants. This rich diversity gives huge social and professional benefit to livery company members.

Fellowship is an important part of company life. Each year there are three formal dinners. These are held in the city’s splendid halls and are an excellent opportunity to entertain clients, colleagues, friends and family.

Delta Launch new MemTech Ground Gas Protection Systems Brochure

October 2018

Delta Membrane Systems Limited, launch new Ground Gas Protection Systems Brochure.

The MemTech gas protection range from Delta provides a comprehensive range of gas protection products and ancillaries to protect buildings from ground gases such as Radon, Methane Carbon Dioxide and VOC’s conforming to the requirements of BS 8485:2015, for both above and below ground applications.

Some below ground construction projects require protection from both water ingress and gas contamination. With innovations of new products, such as the MemTech range, it’s now possible to produce a waterproofing design which incorporates both a waterproof and gas proof protection system. Both BS8102:2009 and BS8485:20015 are intertwined. Basements and below ground structures which need to be watertight and gas proof are not anymore complex to design but require further considerations at the design phase and throughout the project.

The object of structural waterproofing is to protect a structure for its lifetime from water ingress.

The object of ground gas protection is to prevent a build-up of gasses against a structure.

You’ll find all the facts, technical information and inspiration you need in one place in MemTech Ground Gas Protection Systems Brochure. Simply click on this link.

Innovations within the waterproofing sector have seen the introduction of Ground Gas Protection Systems, which can offer both gas protection and waterproof solution.

A Waterproofing Design Specialist will be able to interpret the requirements of BS8102:2009 and BS8485:2015 to produce a waterproofing design which incorporates both a waterproof and gas proof protection system.

Ground Gases Explained

Hydrocarbons

Hydrocarbons derive from the petrol chemistry industry and are highly toxic. Most Hydrocarbons have the potential to cause cancer.

Methane

An odourless flammable gas that is explosive when released into the atmosphere at levels as low as 5% and exposed to a source of ignition. Methane is formed where there is below ground degradation of organic substances e.g. landfill sites, sewage treatment areas, mining operations and peat bogs. Methane can migrate through subsoil and through cracks and fissures into buildings and structures. A build-up of methane to hazardous levels will cause harm to health and compromise safety.

Carbon Dioxide is an odourless and colourless toxic gas. In high concentrations can result in asphyxiation. The gas is formed by the oxidation of carbon compounds such as that which occurs in landfill sites. When Carbon Dioxide levels reach a concentration of 3%, symptoms of headaches and shortness of breath will occur, becoming severe at 5% between 7-10% will cause suffocation.

Radon

Radon occurs naturally in the environment, this radioactive gas is, colourless, odourless and tasteless. Radon can migrate into any building that is built over a source. If it 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).

Volatile Organic Compounds (VOCs) are organic compounds that easily volatise under normal atmospheric conditions/environments to become vapours or gases. Along with carbon, they contain elements such as hydrogen, oxygen, fluorine, chlorine, bromine, sulphur or nitrogen. Typical VOCs encountered on brownfield and industrial sites include: Petroleum, benzene, toluene, butylbenzenes, chlorinated ethenes, Nitrogen, sulphur and tetrahydrofuran. VOCs in the air react with oxides of nitrogen in the presence of sunlight to form ozone.

If a site has been identified with a gas or hydrocarbon contamination it will have been given a Characteristic Situation Score. The Characteristic Situation Score is defined according to how severe the gas flow from the ground is.

All sites which have been characterised with a gas situation score will require a gas protection system and where identified a waterproof protection barrier.

What are the methods of Structural Waterproofing?

There are 3 Types of waterproofing methods. These are defined as:

Type A Tanked or Barrier Protection. Cementitious or bitumen-based products applied internally, externally or sandwiched within the structure.
Type B Structurally Integral Protection. Reinforced or prestressed concrete designed through composite and integrated details such as water bars to be water resistant.
Type C Drained Protection. Cavity Drainage Systems which allow for water ingress but in a controlled fashion.

Evaluation of groundwater conditions, risk assessment and options for drainage outside the structure should always be considered.
