HDPE and HDPP Sheet Flooring Membranes

A range of HDPE and HDPP sheet flooring membranes which provide a damp proof solution for commercial and domestic floors. The membranes protect the floor finish by ‘decoupling’ it from the substrate, preventing damage as a result of movement and/or cracking.

Both Newton’s HDPE and HDPP waterproofing membranes provide excellent protection against water and water vapour; isolating internal flooring from dampness below, as well as contaminants such as alkalies, hydrocarbons, saline solutions and organic acids.

Both materials offer effective waterproofing protection and can be used in conjunction with other Newton products. whilst also protecting against substrate movement

Loose-Laid Flooring Membranes

Newton DampSafe 601 Slimline and DampSafe 603 are loose-laid sheet flooring membranes of 1mm and 3mm thickness respectively. Both can protect flooring from damp slabs and contamination, and can also be used as part of the Newton CDM System below ground or with Newtonite damp proofing membranes above ground.

Decoupling Mat for Tiling Floors

Newton DampSafe 603 Tile D-Mat is a 3mm decoupling mat that isolates the tiled floor surface from cracking or movement in the substrate, and prevents compressive stress from acting on specific points on the tiled floor.

The lightweight membrane is tough and durable, and the fleece surface on both sides absorbs tile adhesive to create an exceptional bond with both the subtrate below and the tiled floor above.

FAQ

What is the advantage of sheet membrane system?

The use of sheet membrane offers the benefit of clear visibility, making it convenient to locate the membrane. Unlike liquid membrane, which can lead to unintended gaps in the seal during application, sheet membrane can be precisely cut to fit.

The Newton Cavity Drain Membrane (CDM) System is a maintainable basement waterproofing solution, certified to BES 6001 by BRE Global, ideal for new-build basements and refurbishment projects.

The four components of the Newton CDM system

Comprising of four components: Cavity Drain Membranes, Drainage, Pumps and Control Systems, the Newton CDM System complies with the British Standard for Waterproofing and provides a Grade 3 habitable internal environment.

Cavity Drain Membranes and Drainage

Cavity drain membrane (CDM) systems are a maintainable, internal basement waterproofing solution, suitable for protecting below-ground environments against water that has penetrated through the structure. CDM Systems are known as ‘Type C’ waterproofing in British Standard 8102:2022 and are ideal for new-build, refurbishment and historic/listed projects.

Known as the most failsafe form of waterproofing, the cavity drain membranes capture ingressing water at the point of ingress, then the CDM drainage system manages and directs the water to an integral pumping system or drainage outlet for safe removal.

The Newton PAC-500 System also provides a combined CDM waterproofing and gas proofing system for below ground spaces that are at risk from ground gases.

Pumps and Control Systems

Once the water has been captured by the cavity drain membranes and drainage channels, it needs to be safely removed. The Titan-Pro is a packaged sump chamber and pump system designed specifically to be used with the Newton CDM System. Compatible with a variety of Newton pumps, it is ideal for almost any cavity drain waterproofing system.

Preformed External Waterproofing Membranes

A selection of preformed external waterproofing and drainage membranes, and Newton’s flagship self-healing Type A membrane HydroBond 403 Plus. Used externally, these products provide waterproofing solutions for earth-retained structures and covered decks.

What Are External Waterproofing Membranes?

External waterproofing membranes are a range of liquid-applied and sheet membranes that can either be post- or pre-applied to the exterior surface of a below-ground or earth-retaining structure.

The membranes are categorised as a ‘Type A’ form of waterproofing as per British Standard 8102:2022, which are designed to resist hydrostatic pressure and prevent water passing through the structure and penetrating the internal environment.

Newton supplies a wide range of external waterproofing membrane products, including our flagship HydroBond 403 Plus self-healing sheet membrane.

Newton HydroBond 403 Plus – Benefits and Applications

Newton HydroBond 403 Plus is a high-performance self-healing membrane that creates mechanical bond with the structural concrete and provides a waterproof envelope around the structure. The gas barrier variant also protects against radon gas, carbon dioxide and various hydrocarbons.

HydroBond 403 Plus is often combined with other Newton products to provide a comprehensive structural waterproofing solution. As a continuous external Type A membrane it is pre-applied to raft and wall formwork prior to the placement of the reinforced concrete.

• Cambridge House Luxury Hotel Waterproofing
• 21 Basements in 1 Project, Clapham Old Town

Newton Drainage Membranes

Drainage membranes protect the external waterproofing membrane and the structure from water pressure, chemicals in the ground and from damage during backfilling.

Drainage membranes such as HydroBond 410 GeoDrain consist of a geotextile filter layer that is thermally welded to a HDPE drainage membrane. This drainage layer prevents water pressure from coming to bear against a structure, provides protection against damaging chemicals in ground water and filters out any suspended soil particles that might block the membrane.

Concrete Joint and Leak Sealing

A range of products used to waterproof construction joints and movement joints of retained concrete structures so that they become integrally waterproof.

The Importance of Concrete Joint Sealing

Concrete joints are essential. They allow the concrete to shrink as it dries, preventing internal restraint which would lead to cracking, and they also allow it to expand and contract under different temperature conditions.

Whilst there are different types of concrete joints, if the structure is below ground then it needs to be protected against water ingress, and waterproofing products will be required to seal them. This is as well as any service or pipe penetrations and any cracks that may also appear in the concrete.

Concrete joint sealing products allow the structure to expand, contract and move without affecting its waterproofing integrity and even prevent contaminants in the soil from entering the structure.

Newton’s Concrete Joint and Leak Sealing Products

Our innovative range of products can be used to waterproof joints in concrete and provide a Type B waterproofing structure that acts as the primary form of resistance to water ingress. This includes all below-ground structures, including tunnels, basements, water tanks, and podium decks.

Concrete injection resins are also an effective method of leak sealing in a wide range of scenarios. From creating Type B waterproof structures using injection hoses to repairing leaks and cracks in existing concrete structures.

• Injection Hose Waterproofing, Jersey
• Resin Injection Leak Sealing, London

Newton 302 Injection Hose

Newton 302 Injection Hose is a high-performance waterbar system for sealing construction joints in earth retaining and water retaining concrete structures. The waterbar is installed within the joint and, once the concrete is cured, an injection resin is pumped into the hose under pressure. The resin penetrates the surrounding concrete within the construction joint, and cures to create a permanent seal for any cracks, capillaries, pores, and honeycombing within the structure.

Depending on the injection requirement, Newton can supply the whole range of high quality acrylic and polyurethane resins from our specialist resin supplier Tradecc.

Mortars and Plasters

A range of cement-based mortars suitable for where a high depth of repair or levelling to concrete is required, as well as compatible plasters for use with Newton’s range of meshed waterproofing and damp proofing membranes.

Rapid Set and High Strength mortars and plaster

Mortars and plasters are essential ancillaries in the installation of effective waterproofing. For example, our cement-based structural mortar HydroSeal 203-RM has been instrumental in a wide range of waterproofing projects. Mostly used for durable repairs to concrete structures, it can also be used to repair bridges, floors, footpaths, roads, runways, and decks.

Mortars such as this are also regularly used for concrete levelling where a completely flat and uniform surface is required quickly. With the addition of water, they create a rapid-curing mortar which will set quickly and be safe for foot traffic within hours.

Benefits of using Newton mortars

HydroSeal 203-RM is a single component, fast setting mortar. It is polymer modified and fibre reinforced with a high adhesion and compressive strength. The mortar can be installed up to 100mm deep, or it can be mixed with sharp sand to create a screed with a maximum depth of 300mm.

Overall, HydroSeal 203-RM provides the following benefits:

• Strong and durable even at sub-zero temperatures
• High bond strength greater than concrete
• Sets in ten minutes for quick application
• Resistant to 10 bar water pressure
• Non-toxic when cured and suitable for use in reservoirs or other drinking water containment areas
• Resistant to acid gases, chloride ions, and sulphates

Tarmac Whitewall Plaster and mixing equipment

At Newton we also recommend Limelite Whitewall Plaster from our partners at Tarmac. Used in conjunction with our range of meshed damp proofing membranes, it provides a smooth white finish which is extremely hard and durable. A two-coat application is required when used with the meshed membranes, but a single coat is sufficient when applied to most other substrates.

To aid with on-site mixing and product preparation, we also supply a range of professional mixing equipment from Collomix. This includes a range of hand-held mixers, stirrers and mixing buckets, as well as a cleaning bucket, mixing stand and transport cart. This equipment helps to maximise mixing efficiency and ensures that all mortars and plasters are properly prepared prior to application.

FAQ

What type of mortar is waterproof?

Waterproofing Mortar is a cement coating that has been polymer modified to provide exceptional performance for both interior and exterior applications. It is specifically designed to effectively waterproof various structures such as basements, foundations, retaining walls, tilt-up concrete, cast-in-place concrete, and precast concrete. This product complies with ASTM C1583 standards.

Does water pass through mortar?

Water can infiltrate a wall system by means of pores and cracks in the masonry units and the mortar joints. However, it is quite common for water to permeate through cracks or gaps occurring between the masonry and mortar.

Liquid Waterproofing Membranes

A comprehensive portfolio of liquid membranes for all substrates and all applications, ranging from very flexible liquid rubber products through to hard wearing and resilient cementitious membranes. Suitable for waterproofing retained structures and both covered and uncovered decks. As well as our liquid waterproofing membranes, we have collomix mixing equipment and flexible construction joint waterproofing, with our System 100 providing a range of superb products.

FAQ

What is membrane waterproofing?

Membrane waterproofing is a type of waterproofing system that is designed to protect a structure from water damage. It can be used in a variety of applications and involves the use of a waterproof membrane, to provide a barrier between the structure and water. This barrier prevents water from entering the structure, protecting it from water damage.

When should you use membrane waterproofing?

Waterproof membranes are used to protect buildings, and other structures such as foundation walls from water damage. They are typically used in areas that are exposed to high levels of moisture or water, such as bathrooms, basements, and balconies. The membranes act as a barrier to water and moisture, preventing them from seeping into the building’s structure and causing damage.
