The Newton HydroSeal System is an Internal Type A Waterproofing Solution for projects that requires an internally applied membrane to resist water ingress.
When waterproofing existing structures to BS 8102:2009, there is often a requirement for an internal waterproof membrane. The range of liquid applied membranes and reinforcement products in the Newton HydroSeal System therefore offer a choice of third-party certified solutions, utilising advanced products that are also quick and easy to apply.
British Standard 8102:2009 defines ‘Type A’ waterproofing as “barrier protection”. This barrier protection can be applied to either the external or internal surface of a structure to resist any water that is trying to enter the building.
Internal ‘Type A’ membranes are often the products that are referred to when people talk about the process of “tanking” a basement to protect it from water.
Waterproofing barrier membranes that can be applied to the internal ‘negative’ side of the structure include a variety of liquid-applied membranes or slurries that can be installed either by spray machine, trowel, brush, or by roller directly onto the internal wall surface.
These membranes must actively hold back any ingressing water, so it is crucial to select the correct product and to ensure that the substrate is prepared correctly.
For more robust waterproofing protection, BES 8102:2009 recommends combining two or more Types of waterproofing. Newton HydroSeal can therefore be combined with Newton's External Type A Newton HydroBond System, their Type B Newton HydroTank System and/or their Type C Newton CDM System.
Professional waterproofing designers should always consider using more than one type of waterproofing to provide enhanced protection to the structure and achieve the necessary environmental grade.
