New concrete replacement Nafufill GTS-HS rapid

Jul 05, 2018

The time window available for repairing hydraulic and sewerage structures is frequently restrictive. And the case of structures in tidal waters, time becomes even more critical – a challenge for planning skill, material selection and work execution alike. Now, with Nafufill GTS-HS rapid, MC-Bauchemie has launched a special fast-setting concrete replacement that can be permanently exposed to water after just one hour, making it ideally suited for the repair of hydraulic and sewerage structures made from concrete.
The polymer-modified, low-shrinkage concrete replacement from MC-Bauchemie is chloride-proof, highly sulphate-resistant, resistant to temperature, frost and de-icing salts and can be applied by dry spraying at air, material and substrate temperatures of 5 to 35 °C.
Exceptionally early permanent water resistance and impressive stress resilience

Nafufill GTS-HS rapid fulfils the requirements for mortar class R4 laid down in EN 1504 Part 3 and is thus also approved for strengthening structurally relevant areas in concrete structures. The new concrete replacement material cures extremely quickly and can be permanently exposed to water after one hour. It achieves flexural and compressive strength values of 2.9 & 10 N/mm² respectively after 24 hours, 5.9 & 31 N/mm² after 7 days and 10.9 & 62 N/mm²* after 28 days.

 

With new Nafufill GTS-HS rapid, fractured areas between the low and high water marks can be repaired with layer thicknesses of up to 120 mm. The concrete replacement can also be applied as a wide-area coating. The minimum layer thickness is 10 to 30 mm per pass, up to a maximum total layer thickness of 60 mm.

 

Wide range of applications for all kinds of hydraulic structures

With these properties, Nafufill GTS-HS rapid is not only a reliable and sustainable solution for the repair of tidal, reinforced and unreinforced hydraulic structures such as port infrastructure, embankment walls, quay facilities, locks and sluice structures, but also for the repair of sewerage structures, open sewers, emergency basins etc.
