First introduction to Natural Cement was a water authority contract for Yorkshire Water at Dunford Bridge near Holmfirth. The specification was for SHOTCRETE 513 due to its WAA status. The environmental considerations were paramount, and it’s inert nature and short curing times were fundatmental in its inclusion in the restrictive specification, which was for slope stabilisation on a primary drinking water reservoir. Since the successful completion of this contract, SHOTCRETE 513 has been our first choice for dry sprayed material within enviromentally sensitive areas such as rivers or water authority structures. An example of this was the limestone canal tunnels contract in Dudley, West Midlands, where SHOTCRETE 513 was sprayed onto the roof of unstable limestone tunnels for stabilisation. In addition, due to its water proofing and water stopping properties, it has also been utilised for areas of substrate with severe water egress such as piled walls and tunnel linings and has proved very effective in difficult circumstances, even as far as having been sprayed onto flowing water, all areas that would require expensive counter measures to prevent water egress. Natural Cement is not a cheap material when compared to standard construction grade dry spray products, but is priceless in the previously mentioned environments.
