Newton HydroTank 315 Waterbar for Sealing Structures Against Water Leaks
A high grade, hydrophilic waterbar with high elasticity and high tensile strength, made from a polymer which swells when in contact with moisture, ideal for sealing structures against water leaks to both cast-in-place concrete and precast construction joints.
The swelling is achieved through hydrophilic acrylate polymers, which are inseparably embedded within the butylene carrier material. This results in high elasticity and exceptional tensile strength, even when fully expanded within the joint.
Due to its high resistance to acids, alkalis and organic solutions, HydroTank 315 Waterbar can be used to seal joints where aggressive water is expected such as within sewage treatment plants, biogas plants and liquid waste holding tanks.
HydroTank 315 Waterbar swells up to 9 times its original size when in contact with water, sealing the joint fully and reliably. The product is particularly suited to sealing non-compressed joints such as at the junction between slab and wall.

Newton HydroTank 301-EP Metal Construction Joint Waterbar
Coated metal waterbar system used for sealing kickerless construction joints within retained concrete structures. It features an adhesive, reactive polymer coating on one of its sides which creates a permanent watertight seal that works immediately.
Installation is quick and easy with the waterbar fitted in place to the reinforcement steel with special clips so that after the placement of the concrete, the waterbar is fully embedded within the two adjoining elements, completely blocking the passage of water through the joint.
Because HydroTank 301-EP Metal Waterbar is not fixed to one of the concrete elements as is the case with conventional waterbars, the forming of a kicker is not necessary. Where the walls are formed above a kicker joint, use 315 Polymer Waterbar.
Newton HydroTank 301-EP Metal Waterbar is certified to resist water pressure of up to 5 bar (50m) and is resistant to all types of naturally occurring ground water types.
HydroCoat 1 Screed 2K
Self-levelling waterproof performance: HydroCoat 1 Screed 2K is a cement-based screed enhanced with epoxy and polymers, designed to level and waterproof concrete. Its free-flowing mix can be poured or pumped to create a smooth, durable, lightly textured finish.
Fast-setting and hard-wearing: It cures rapidly to produce a strong, abrasion-resistant surface that can handle foot traffic and allows resin coatings or screeds to be added within 4–24 hours.
Dense and protective: Its cementitious structure offers low water absorption and high wear resistance, delivering dependable waterproofing and long-term durability in demanding indoor settings.
Damp Tolerable, Vapour Barrier & Primer for Porous Services Newton Epoxy Primer
Two-part, solvent-free and clear epoxy which is applied to damp and porous surfaces as a pre-primer prior to the application of Newton Epoxy DPM, a vapour barrier and primer for newly placed or damp concrete and screed.
The high-quality, epoxy formulation allows for application onto damp surfaces, whilst the low-viscosity penetrates deep into porous substrates to effectively seal the surface ready for the main primer application.
Newton Epoxy Primer is quick and simple to apply by brush or roller and can be applied over cementitious screeds and concrete just 7 days after placement.
Features and benefits:
- Very damp-tolerable.
- Can be applied to concrete and screed seven days after placement.
- Low viscosity.
- Solvent free.
- Provides an excellent vapour barrier.
- High-bond damp proof membrane (DPM) that provides a barrier to vapour and to prevent osmotic blistering.
- Life expectancy is equal to that of the surface it is applied to.
Suitable substrates:
- Indoor or outdoor floors of correctly formed, compacted and prepared:
- Concrete, at least seven days old;
- Screed, at least seven days old.
