Taking a subtle approach

I REFER to Mr Graeme Roberts' letter (South China Morning Post, November 28) regarding the adding of colour to shotcrete slopes.

We have had a couple of private clients who are a little more adventurous than the Government. Mr Roberts can see the results if he takes the Tai Tam Road from Stanley. The Hong Kong International School at Red Hill decided that its own works which required a large shotcrete slope within a country park were not acceptable. We were commissioned to do something about it.

The costs were not great and even the vegetation planted to replace the lost slopes seems to be benefiting from the reduced glare. We do not want this to be perceived as an alternative to vegetated slopes as these should always be the primary goal, but if it has to be shotcrete it is possible to be subtle.
