NEWTON SYSTEM 500 is designed and ideal for many applications:

• Renovating or extending existing homes - transform a wet basement to make a warm dry space suitable for a home office, an extra bathroom or extra storage space or maybe even for the basis of a perfect wine cellar - whatever you plans our specialists can help you turn that damp wet cellar space into a warm dry and valuable feature of your property.
• Basement construction in newbuild homes - with higher density housing and the increasing use of brownfield sites - provide habitable basements in newbuild projects thus enabling the maximum living space, potential and value from each home built.
• Stopping damp and wet unwanted contaminants - from entering your living space - an impermeable barrier to damp and wet that will last even where walls and floors are contaminated by salts, oils, mould or chemicals.
• In construction areas - laid above a 'green' slab can be finished with a moisture sensitive flooring system immediately after installation. SYSTEM 500 requires no wet trade involvement and is cleaner as a result.
• In underground areas - subject to high-ground water levels and flooding i.e. basements, cellars, vaults, tunnels, underground passage ways.
• In areas subject to vibration - where it is necessary to create dry surfaces, typically railway stations and tunnels.

NEWTON SYSTEM 500 membranes and accessories:

1) Newton Nuseal Fixing Plugs 2) Newton Waterseal Tape 3) Newton Waterseal Rope 4) Newton Corner Strip 5) Newton 500 Lath

The main component of the system is a high density extruded membrane with a thickness of 0.6mm and a stud formation with a height of 8mm. The studs serve to hold the product away from the areas that are being treated allowing an air gap of 5.5 litres per m². Water vapour can therefore move unhindered in all directions and damp pressure equalisation is achieved. So that in simple terms, the whole of the area being treated is taking the damp loading rather than just the weakest areas as is the case with conventional systems. The system remains flexible as do the various sealing products. It can therefore be used in areas where cement based systems are prone to failure, such as under street vaults and areas subject to high vibration etc.

Preparation prior to installation of NEWTON 500 is minimal. There is no need to remove sound cement based renders or other failed bitumen type coatings. Compared to conventional cement and epoxy type systems which rely solely on their ability to bond to the substrate; which usually requires bush hammering, and or sand blasting. Both can be time consuming, destructive, and costly. NEWTON 500 relies on a physical fix and is not only more sympathetic to the structure but is also usually installed more quickly and cost effectively without any compromise on performance.

Where "fast track construction" application is important NEWTON 500 has the answers. The system can be fixed with speed and can be ready for decoration very soon after installation. The drying times associated with conventional cement based systems (6-12 months), are eliminated.

 

 

In new basement construction or where it is feasible to remove high external ground levels, NEWTON GEODRAIN can be used to protect the building from dampness on the positive side of the structure. This completely removes the effects of the dampness on the walls. NEWTON GEODRAIN will allow the construction to dry out, and remain dry . Damp walls have a reduced insulation value, and if maximum heat retention is to be achieved, external application during construction is preferred.

NEWTON SYSTEM 500 is ideal for cellars basements but also arches, tunnels and vaulted ceilings. Vaults can suffer from water ingress from above as well as lateral ingress from water pressure within the ground. In the diagram to the right, NEWTON 500 has been used to line the vaulted soffit and walls to divert water to the floor. All joints for where flanged junctions are located should be sealed together with NEWTON WATERSEAL TAPE. Where studded junctions meet, the NEWTON WATERSEAL ROPE should be applied. Where service pipes enter through walls to be treated a seal should be effected between the service and the System using either NEWTON WATERSEAL TAPE OR NEWTON WATERSEAL ROPE. Where old decayed pipes exist these may have to be cleaned down, and made compatible to the system by the use of either a bonding agent or an epoxy based paint. Water is then removed using a floor membrane with a drainage conduit such as NEWTON BASEDRAIN or NEWTON BASEBOARD in conjunction with a NEWTON TITAN or TITAN PLUS sump pump.

The fixing component used with the sealed system is usually the NEWTON WATERSEAL PLUG (red or white in colour) which is inserted into a pre-drilled 11 mm hole. This completely sealed plug has a dual role. It holds the sheet in position and the 6mm hole within the centre of the plug also facilitates the fixing of battens so that there is absolutely no need to pierce the system for any reason. The product, its fixing, and sealing components are of contrasting colours to make identification during installation easy and to eradicate mistakes. Where plastering direct or dry lining with dabs is required the NEWTON 500 LATH membrane should be applied, which has a welded mesh on the face of the product to give the required key. NEWTON 520 (20mm stud) or NEWTON 500 (8mm Stud) membrane can be applied to floors.

Converting Vaulted Basements:

Under street vaults were originally constructed to store solid fuels in bygone days. With soaring property prices and with many large Victorian properties having already been converted into small flat units, many property owners and developers have seen the benefit of upgrading their previously unused space. Dry usable areas have now been created. Many such areas now exist as bathrooms, dry storage areas and play rooms etc. As many of these vaulted type basements extend under the street, they are usually subject to vibration from traffic etc. NEWTON SYSTEM 500 being flexible can easily cope with this situation. An average vaulted basement can be upgraded in a few days to a dry habitable space.

NEWTON SYSTEM 500 range applied by Newton's Qualified Installers:

Although NEWTON SYSTEM 500 is, by comparison easy to install, if must be recognized that correct diagnosis of the problem is essential so that NEWTON SYSTEM 500 can be tailored to the needs of the building, to give the best possible performance. It is therefore recommended that only competent specialist damp proofing contractors, who understand dampness and the associated problems, be employed to survey the site, and install the system thereby ensuring the best possible performance of the system. John Newton & Co Ltd have a nationwide network of Newton Registered installers who have received the necessary training, and are holders of the Company's Registered Contractors Certificate.

BACKGROUND TECHNICAL INFO

NEWTON SYSTEM 500 and BS8102:

The system is certified by the British Board of Agrement and is deemed fit for the purpose for use in accordance with BS. 8102 : 1990 (Type C Drained Protection).

Anyone involved in a refurbishment or 'new build' project involving a basement should be aware of the recommendations within BS8102: 1990 (please refer to the backgound technical info below and the relevant British Standards document for full details).

Almost all structures that are partially earth retaining, or fully below the ground, are likely to be subjected to hydrostatic (water) pressure at some time in the future. If this pressure is unchecked it can lead to water ingress which is very distressing to the occupier and can even lead to failure of the structure (see pictures below). Changes in climatic conditions and rising water tables mean basement water problems are becoming an all to frequent occurrence. NEWTON SYSTEM 500 prevents the build up of hydrostatic pressure and this type of protection is considered to be the most effective and trouble free form of basement waterproofing.

Many professional specifiers are moving away from conventional sealed tanking and are finding that NEWTON SYSTEM 500 is quicker and easier to install - even more importantly, correctly installed, NEWTON SYSTEM 500 is proven to work when tanking has failed.

THE PROBLEM - HYDROSTATIC PRESSURE:

During periods of sustained or heavy rainfall, the ground surrounding the structure becomes saturated with water. The depth of water surrounding the structure creates water pressure relative to the depth of the saturation and the depth of the structure below the ground. Once the pressure is greater than the resistance of the structure, leakage or flooding occurs.

Hydrostatic pressure causing Massive Structural Failure

Hydrostatic pressure causing water to leak through basement wall

A common mistake when treating earth retaining structures is to damp-proof when waterproofing is required. In basic terms, you damp-proof above the ground, and you waterproof below the ground. A structure that has been damp-proofed or poorly waterproofed will most likely fail if subjected to external water pressures. It is therefore important to get it right the first time!

THE SOLUTION - NEWTON SYSTEM 500:

BS8102 states that a “Type C” Drained protection type of construction is considered to be the most effective and trouble free form of basement waterproofing." The whole document is some 38 pages long, and we are therefore unable to represent the document in full. However, we have included some pertinent paragraphs: "Almost all basement structures are likely to be subjected to water pressure at some period of their life". "For basements not exceeding 4m deep, a design head of ground water, three-quarters the full depth below ground is adequate". In layman's terms BS8102 is saying that we should always expect water ingress at some point; and that we should expect the water surrounding the basement to be at least the depth of the basement. This is very important as it confirms that one should always waterproof and not damp-proof any structure that is earth retaining. Being a cavity drain membrane system, SYSTEM 500 is categorised as Type C. (drained protection).

NEWTON 500 membrane (illustrated in black on the right) allows for any water ingress to be controlled and discharged from the structure. When fitted to the walls and floor of the structure the membranes create a dry and habitable inner environment, whilst the waterproofing carries on unnoticed behind the system. Requiring very little substrate preparation, NEWTON SYSTEM 500 is much quicker to install than tanking products such as asphalt, dense renders and paint on or sheet bitumastic systems. In many cases, NEWTON SYSTEM 500 can be installed in the time it takes to prepare the substrate for tanking that requires damaging processes such as grit blasting and scabbling.

Installation is quick, with no heating mixing or torching required.

NEWTON 500 can be installed with a minimum of fixings and finished with an independent dry-lining frame. It is quick, simple and none destructive to remove the system in the future. Tanking preparation is often prohibited to listed properties, and removal would be difficult and potentially destructive also.

See some examples of where System 500 has been applied

Resolve Condensation problems using NEWTON SYSTEM 500:

NEWTON SYSTEM 500 is used where persistent condensation occurs. When installation is complete the increased insulation properties of the system raise the temperature of the finished wall surface. In all but the most extreme circumstances, the wall then remains above dew point and therefore, mould growth and damage to decorations are no longer a problem. In certain circumstances extraction and/or dehumidification of the internal air is included into the specification. This gives complete control of the internal environment. In extreme conditions the specification can be expanded further to provide an overall control programme.
