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.

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 - What are the benefits of using Root Barrier Protection in green roofs?
What are the benefits of using Root Barrier Protection in green roofs?
When it comes to building sustainable homes, green roofs are one of the more popular options, given both their “green” factor and aesthetical appearance. Not only do green roofs reduce our carbon footprint but are also beneficial not only to our own health, but to those around us.
There are two types of green roofs: Intensive and extensive.
Intensive green roofs are essentially elevated green spaces. Able to sustain shrubs, trees and patio areas.
Extensive green roofs require less maintenance than intensive green roofs and exist more for their environmental benefits as to functioning as a rooftop garden.
Whether intensive or extensive, the layers which form the green roof must accommodate both drainage and waterproofing capabilities.
Waterproofing systems have an incredibly important role to play in the success of a green roof. Not only required to prevent water ingress but to also resist damage to the structure from root penetration.
Not only do waterproofing systems need to be functional as a water proofer but they should also be able to provide the building with thermal performance, roof drainage, air tightness and vapour control. A green roof construction involves a series of functioning layers that, while retaining the necessary water to support the plants/trees/shrubs will also allow excess water to drain off whilst protecting the roof surface from both roots and mechanical damage.
Root barriers are often used in conjunction with waterproofing systems when creating robust green roofs, blue roofs or hybrid roofs.
Root barrier membranes provide protection to the underlaying waterproofing system, often referred to as the primary water proofer. These root barrier membranes protect the waterproofing system from invasive woody roots.
Installing a green roof is relatively straightforward. Once designed, to meet not only building regulations but also client requirements each layer is built into the design. Once a suitable primary waterproofing layer has been installed to the roof deck, this is followed by insulation, a green roof drainage layer, a root barrier followed by a green roof drainage layer. Each membrane layer is supplied in rolls. With lengths of membrane cut to size and abilities to overlap where needed to create a robust solution. Finally, substrates can be added, with an even spread of roof soil across the entire roof area – finally comes the planting of seeds or vegetation layer.
As with any waterproofing system, it’s always important to check the compatibility of the products, using a single source to procure waterproofing systems can offer numerous benefits from warranties to reassurance the products will function as intended.
Delta Waterproofing for Homeowners – when waterproofing is required
Waterproofing for Homeowners – when waterproofing is required
For many homeowners waterproofing is a mystery. It is a niche, unseen element required for any below ground structure.
You have appointed an architect, you have the plans and the builder in place to create your new basement extension, but in what order is everything going to happen and why are waterproofing design consultants required?
Put quite simply, structural waterproofing is a long-term cost-effective way to maintain the value of your home.
British Standard BS8102:2009 (Code of Practice for Protection of Below Ground Structures Against Water from the Ground) is the standard which governs the waterproofing industry and is often used as a benchmark in failed litigation cases. These stringent standards cover durability, exposure and stress conditions ensuring effective waterproofing is the cornerstone of project success.
Section 4.2 of BS 8102:2009 under the heading “Design Team” states “A waterproofing specialist should be included as part of the design team so that an integrated waterproofing solution is created.”.
For all below ground structures, waterproofing is a necessity to provide a dry internal environment. It should be assumed that at any stage during the life cycle of a below ground structure, water will come to bear on it. From changing weather patterns to a periodic rise in the water table.
Failure to protect any below ground structure will most definitely lead to a physical attack on the structure itself, from compromising on water tightness to durability and a reduction in the life cycle.
A waterproofing design consultant should be appointed at the earliest stages of a project, but can be brought onboard at any time – even when waterproofing solutions haven’t been included in original plans and works have already commenced (although we do not encourage this).
Waterproofing below ground structures is achieved through careful design, the right choice of materials and professional workmanship.
A Waterproofing Design Specialist will consider a number of factors when specifying a suitable waterproofing system.
• The client’s requirements
• The internal use of the structure
• External effects on the structure, such as soil and ground conditions
• Whether options are limited to the confinements of the project
• Maintenance of the system
• Possible future failure and designing out risks
Installation of structural waterproofing systems are usually undertaken by expert contractors.
