Roundtower 5.0 Natural Hydraulic Lime is eminently hydraulic. This material is used in areas of high exposure such as marine environments, wall copings, lime concrete etc. Roundtower NHL 5.0 offers the maximum strength of the 3 classifications for NHL (Natural Hydraulic Lime) and as such we would advise caution as to exactly where it’s to be used.
It can be used for most typical mortar applications, especially those in more aggressive environments, and only then onto suitable, durable backgrounds; this is a binder with limitations in conservation. However, it will make an appropriate masonry mortar for marine applications including those within the tidal zone or flow in rivers and streams, etc.
Roundtower NHL 5.0 is used extensively for limecrete flooring.
Roundtower NHL will set in the presence of water which makes it ideal for use on exterior applications.
