Main Products & Applications:

Structural Waterproofing:

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.

Waterproofing Buried roofs/Podium Decks/Balconies & Terraces

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

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).  

Ground Gas Protection Systems

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.

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.

Delta Membrane - Public House Cellar Conversion

December 2019

The Northernmost of the inhabited Channel Islands, is Alderney. A spectacular remote island steeped in natural beauty and never-ending stretches of white-gold beaches.

Encircled by the quiet cobblestoned streets of Saint Anne that lead to Alderney’s dramatic coastlines, is The Blonde Hedgehog.

The Blonde Hedgehog, originally a public house, has dramatically been developed into a luxurious gastropub and hotel. The Blonde Hedgehog is linked to Clarence House and The Corner House, warm and welcoming hotels which offer a deluxe haven to all who stay there.

Delta Registered Installers, Oaks Damp Proofing having previously undertaken work for the client were commissioned to design and install a Cavity Drain Waterproofing system that would meet BS8102:2009 the British Standard for the protection of structures against water from the ground, Grade 3 (no dampness or water penetration acceptable) to the cellar area of The Blonde Hedgehog.

The Cellar having been used historically to store beer was not waterproofed historically. Beer cellars are notable for being very cold and wet. For hundreds of years beer cellars were always underground – because underground rooms are generally quite cool.
Methodology

After undertaking site inspections to the structure, Oaks recommended installation of a Delta Type C Cavity Drainage System.

The cellar area was fully earth retaining and boarders the main road which meant there was a lot of hydrostatic water pressure bearing against the structure.

To reduce risk and slow down the volume of water entering the structure, Oaks treated the walls of the cellar with the Koster KD System.

The main contractor incorporated a new basement slab to the cellar which allowed for incorporation of the Dual V3 Sump Pump and channel recess. Prior to the installation of the Delta Type C System all new concrete was treated with Koster Polysil TG 500, an anti-lime inhibitor.

Preceding the installation of the Type C Cavity Drainage System, Oaks ensured the waterproofing design would easily be maintainable and repairable.

The benefits of using a Type C Cavity Drainage System enables the management of any water ingress in a controlled process. Any moisture or running water ingress travels behind the membrane to be diverted to a Delta Submersible Pump allowing for the required Grade 3 environment.

All installed with great dealing and expertise.

Case Study Results

The Blonde Hedgehog’s cellar has been converted from an unused room into a desirable relaxation area for diners and hotel guests. By incorporating a Delta System, the cellar is completely protected against water ingress along with assurances for the owner, with Delta’s tested product life cycle and installation by Delta Registered Installers that the project easily complies to British Standards.

The customer was absolutely delighted.

Delta’s Waterproof Consultant & Architect, Michael Vernon considers Waterproofing

November 2019

Delta’s Technical Waterproofing Consultant and Architect, Michael Vernon considers Waterproofing Design philosophies

There are many common pitfalls when it comes to designing a waterproofing system for podium decks, buried roofs, balconies and terraces. Products do not fail! When failures occur, it is due to the design and build philosophy not being correct. The devil is in the detail – all waterproofing elements must be considered at the construction design stage to be durable and effective.

The trend for outdoor living has led to a market growth in external balconies, large roof/ground floor terraces and patios. As well as adding monetary value to a property, external areas can be aesthetically pleasing, offering a wide range of colours, textures and finishes to a home.

Outside living can also help to promote health and well-being benefits as these extra useable areas for open air living, help to soften heavily urbanised locations and steadily increase the number of green and usable spaces for leisure.

Balconies, roof terraces and patios are part of a trend which is inspired by aspirational and luxury living in suburban and rural areas alike.

When specified with the correct waterproofing systems, all types of installations are possible, however the design needs careful consideration and a CSSW qualified Waterproofing Design Specialist should always be consulted at the earliest opportunity.

The primary requirement of waterproofing design is the prevention of water ingress and the management of water and water vapour movement through and out of a structure. The design ethos for waterproofing podium decks, buried roofs, balconies and terraces is identical to that used in any below ground area of a structure.

There are many different approaches to structural waterproofing. The construction methods will in part contribute to the specification of types of waterproofing systems and may also determine the overall structural waterproofing strategy.

Structural waterproofing falls into 3 categories:

Type A – Barrier Protection

Type B – Structurally Integral Protection

Type C – Drained Protection

With 3 grades:

Grade 1 – Some water seepage and damp are tolerable depending on the intended use

Grade 2 – No water penetration is acceptable

Grade 3 – No dampness or water penetration is acceptable

Successful waterproofing design lies with choosing the most appropriate combinations of structure and waterproofing system to achieve pre-determined performance levels and criteria. In order to design out risk of failure due to less than adequate workmanship, damage or defects on site it is also important to consider practicality and ease of installation, the phasing of the construction process and the scope for testing and certifying during construction.

In summary, it is the duty of the waterproofing designer to assess a variety of factors and variables simultaneously and to come to a logical and balanced decision regarding the design. Working as part of the design team and keeping abreast of changes, revisions and updates to the project is important because these could have a bearing upon the environmental, structural and other stresses that may be imposed upon the waterproofing system and adaptations may need to be made. Ensuring proper training, application expertise, certification and testing procedures on the part of the installing contractor is critical. Whether the proposed construction is warm roof, cold rook, green roof, blue roof or a combination of types the principles stated here will apply in equal measure to achieve a successful long-term outcome.
