Structural Waterproofing:
Newton Waterproofing Systems provide full structural waterproofing solutions for both the refurbishment and new-build arenas to protect the entire structure from water ingress.
Newton provide waterproofing products for all three types of waterproofing as defined within BS8102:2009:
- Type A (barrier) protection – Newton System 100 and Newton System 400
- Type B (structurally integral) protection – Newton System 300
- Type C (drained) protection – Newton System 500
Damp Proofing:
Damp problems such as rising damp and penetrating damp lead to damp walls, and can seriously damage your property. Even minimal damp penetration or rising damp will cause discolouration to surface plaster on walls, decorations and can even affect a building’s structural integrity. Newton Waterproofing offer a wide range of BBA approved damp proof membranes and ancillaries which are quick and clean to install and offer a permanent solution for damp proofing above ground walls.
Basement Waterproofing:
Newton System 500 Internal Basement Waterproofing: For basement waterproofing (often referred to as tanking), Newton System 500 offers a proven, innovative and highly effective waterproof membrane solution.
Newton System 400 External Waterproofing Membranes: When placed to the retaining wall these membranes protect the primary waterproofing membrane from impact and water pressure, diverting water down to a perforated land drain for removal.
Deck Waterproofing:
The waterproofing of podium decks and balconies is often an important requirement of a complete structural waterproofing solution. Due to the clients’ requirements to maximise the available space, we frequently find that the below ground structure will extend beyond the footprint of the above ground building. It is therefore essential that these areas and the detailing at ground floor level are completely impervious to water ingress.
Ground Gas Waterproofing and Radon Protection:
The Newton PAC “Positive Air Curtain” 500 System is a combined basement waterproofing and ground gas mitigation system which successfully controls both water and gas levels within below ground/retaining structures.
Sump Pumps & Packaged Pumps:
Whether you need to control clear ground water, grey water, effluent or sewage, Newton supply a complete range of the highest specification pumps available for all of your pumping requirements.
Damp Floors:
For treating damp or wet floors, we supply a full range of floor membranes. All our floor membranes can be used as a stand-alone product for dealing with a specific damp floor problem, or they can be used as part of a well designed Newton System 500 waterproofing scheme.
External Drainage:
Newtons supply two quality external drainage membranes for the reliable removal of ground water. Newton 406 Geodrain has a 6mm drainage layer and a vertical water flow of 1.27 litres per metre squared per second. Newton 410 Geodrain has a 10mm drainage layer and a vertical water flow of 4.60 litres per metre squared per second.
Concrete Structures:
Newton System 300 products are used to waterproof joints and service penetrations to concrete elements, to provide Type B integrally waterproof retained structures that require no further waterproofing to be completely watertight.
Range highlights include 301 EasyProof metal waterbar which gives instant protection to construction joints and injectable waterbars that allow for post construction grouting and resin injection of leaking joints. Construction joints can be further waterproofed with Newton FlexProof, a very flexible polymer that is applied over the completed construction joint, either externally or internally.

Concrete Waterproofing Explained
Reinforced concrete, when designed and installed correctly, is already waterproof. Good concrete waterproofing design therefore focuses on the gaps in the structure. Here is how to protect a structure from leaks.
What is 'Type B' Waterproofing?
Put simply, Type B waterproofing is when the structure is integrally waterproof and prevents water from getting in.
To create a ‘Type B’ structure, reinforced concrete that is designed and installed correctly already provides this level of protection.
Water will always follow the path of least resistance, meaning it will try to enter a structure where the concrete isn’t, rather than where the concrete is. This is because concrete is inherently waterproof – good concrete waterproofing design therefore focuses on the gaps in the structure.
Where a habitable basement is required, other forms of waterproofing then need to be introduced to reduce the likelihood of water getting through, this is known as Combination Waterproofing.
What is the Importance of the British Standard for Waterproofing?
"Reinforced concrete structures may be designed and detailed specifically to minimize water ingress with no additional protective measures... A degree of resistance to water vapour transmission is also achieved dependent on section thickness. The pattern of any seepage encountered is often associated with poor joints, cracks or other discontinuities such as service penetrations.”
- British Standard 8102:2009, Chapter 9.2.1.1 - General Note 1
In short, good concrete is waterproof already. Your efforts should therefore focus on getting the concrete right, then waterproofing the defects.
Helpfully, the British Standard also provides a list of potential defects:
- Badly poured concrete
- Foreign objects in the formwork
- Poorly prepared joints
- Service penetrations
- Movement joints
- Cracking (in its many different forms)
Overall, the best way to deal with these is to plan for them when designing the structure - something that Newton's waterproofing designers can help you with.
How Do You Get a Waterproof Concrete Structure?
It is highly important to select the correct, high-performance concrete mix to suit the project. Such mixes will already include additives that give the concrete desirable benefits. For example, ‘plasticisers’ which enhance the concrete workability, or ‘pozzolans’ which assist with concrete density and prevent cracking.
It is also important to minimise any cracks to a width of 0.2mm, by correctly engineering the reinforcing steel, or by using the ‘White Tank’ method.
Normally performed by specialist engineers, a White Tank system deliberately creates cracks in the concrete in carefully planned locations, then seals the cracks to make them completely waterproof.
When performed correctly by skilled operatives, White Tank systems prevent defects and delays, and offer a high level of quality assurance.
The Cost and Risk of Structural Waterproofing
Focusing on the defects is both the best way to waterproof a concrete structure, as well as the most cost-effective and risk-averse. In contrast, adding further products to the main body of the concrete can be an expensive procedure that does not deliver any additional benefits.
The Newton HydroTank System contains a choice of high-quality products that provide robust structural waterproofing to achieve a “Type B” structure, compliant with the British Standard:
- Hauff-Technik - a range of products for sealing around any services or pipes entering through the structure.
- Newton 104 - a liquid product that penetrates concrete and prevents the movement of moisture.
- Newton System 300 - a choice of waterbars, waterstops and resin injection products for concrete joint waterproofing and leak sealing.
Overall, the best concrete waterproofing systems are those that are included in the design process as early as possible, and which use the expertise of a specialist waterproofing designer.
This includes Type B waterproofing designs, where the most cost-effective and low-risk systems focus on good quality concrete with effective waterproofing protection at the joints and gaps in the structure.

Our award-winning recycling service has been in action now for over 2 years and is still the first and only such scheme in the UK waterproofing industry, made possible with the help of our Specialist Basement Contractors (NSBCs).
Newton’s dedicated drivers pick up waste HDPE membrane from NSBC sites and offices when delivering new product, preventing further carbon emissions. Once collected, the membrane is turned into pellets at our head office in Tonbridge, Kent, before being collected by a third-party recycling organisation and manufactured into new construction products. This achieves an entirely closed-loop recycling process.
We are very proud of our recycling service as it directly tackles an inherent problem in the waterproofing industry that no other supplier has yet managed. High Density Polyethylene (HDPE) is used to manufacture one of the primary forms of below-ground structural waterproofing - cavity drainage membranes. However, every year thousands of tonnes of membrane off-cuts end up in landfill as they are too small for reuse in waterproofing. As the membrane is made from virgin HDPE though, it is perfect for recycling.
2019 So Far
Last year, the Membrane Recycling Service recycled 5.275 tonnes of waste HDPE membrane. Now in 2019, we have succeeded in recycling 2.148 tonnes so far! With 7 more months of the year to go, we are confident that we will be able to prevent well over 5 tonnes of HDPE from going to landfill. To translate this into more quantifiable numbers, that’s 9,646.85 kWH of energy saved so far in 2019, which is enough energy to make 342,999 mugs of tea!
Everyone at Newton is excited to see the continued progress of the Recycling Service, especially as we continue to search for new ways to lower our carbon footprint and decrease our impact on the environment.
