I rang Carl of Amenity Technology and told him I got his number from Mark at AELTC. He couldn't give me much of an idea how much we would need to completely resurface. He said it all depends on the depth of the court. I would have thought there would be a recommended depth. He said Mark at AELTC is the best in the business and has been installing courts for 20 years. He said we should take Mark up on his kind offer to look at our courts.

The shale is imported from Terre Davis in Italy and arrives in Hull. It comes in fine and medium grade plus another grade which may be used as a base layer. Several of our members have played at Ashford Tennis Club who use this supplier and really like it.
Clients:

(and now) Sutton Churches Tennis Club
Cost:
More than 7 times cheaper than Amenity Technology (not including delivery)
Approx. £206 per palette inc. VAT (just over 1 tonne)
Delivery is usually £40/tonne.
1 palette = 35 x 30kg bags = 1050kg
Fine grade is approx. £10 extra per palette.
(In 2001 Ashford ordered 1 tonne for £188.90 + £55 delivery.)
The Deal:
Originally we thought we may be needing to completely replace all the shale on the courts and would therefore be making a very large order. In the end we did not require nearly so much shale but this is the deal we were offered at the time for a large amount. (From letter received 10/10/2003.)
Recommended amount per court: 32 tonnes medium, 2 tonnes fine; Total 136 tonnes. (But our courts are smaller than the standard area so we could use less.) 126 tonnes = 119 tonnes medium, 7 tonnes fine. I was surprised by the small proportion of fine and will query this.
Order 126 tonnes (5 truckloads exactly) for 5 x £5,404.60 inc. VAT & Del = £27,023.
[Normal cost of 126 tonnes inc. delivery = £30,996, so a discount of 12.8%].
Price per tonne = £214.47.
Merrick Howse rang me back on 2/10/2003. He said the material comes from Italian family company Terre Davis
www.terredavis.it
. It is very like the old Heaseldens material. (Heaseldens went out of business in about 2000 because Environmental Health said they had to make the process less dusty. They didn't think it was worth the extra expense.) He said he got the LTA to assess samples of various shale suppliers and the Terre Davis was considered very good. Apparently proportions of medium and fine grade are a matter of taste. 2/3 medium:1/3 fine is probably average for British courts, the more fine grade you have, the more they will be like continental clay courts. I explained that we had heard the courts take a long time to bed-down. He thinks Terre Davis would dispute this and that we should be able to get all four courts ready for the spring. He suggested that the Terre Davis shale has about 5% clay which allows it to bind more quickly.
Letter Received 10/10/2003: Quoting amount of shale required (126 tonnes) and costs. Also the courts should be playable 1 week after relaying. Mr Garavelli will be happy to come over to supervise the relaying of the courts and to give the benefit of his lengthy experience in court preparation and maintenance, although he would like to be assured of an order before committing to a visit.
Some extra notes from Mr Howse on the various materials:
"French Clay is exactly the same material as Heaseldens used to supply, and as supplied from Terre Davis (if you look on the Terre Davis web site you will see a picture of the bricks stacked up ready to be ground in to shale), it is just ground finer than the "medium". It is not true that French Clay is not frost resistant. Part of the secret of a good shale court is that the shale has a very small mix of unfired clay and this improves the binding properties to the previous surface. If you want a French Clay court you finish with a 5mm layer of "Fine" grade, otherwise just use the "Medium" grade which is almost exactly analagous of the English shale from Heaseldens. As they are all the same material then there is no real difference in the frost resistance, although quite a lot of work has been done on mixing shale with various salts such as Calcium Chloride. This has the same action as spreading salt (Sodium Chloride) on icy paths, but has the added benefit of also attracting moisture out of the air in summer so they stay damp for longer after watering. I note from John Lord's e-mail that he is having problems with grip on a "blaes" surface, or on the red granite (the two are not the same). The research on shale courts in the US shows that the least injuries occur on shale compared with any other surface, and my old joints tell me they are much better than tarmac."

Don't know - Ashford were not impressed with the colour.
Cost:
A bit cheaper than Merrick Howse, we think.

Make Redgra (only one grade) which can be bought from Sportsequip.co.uk. I went direct to the company that produces it and am awaiting email reply. I am not convinced that Redgra is a satisfactory replacement for traditional shale.

Sell Redgra but advised me it is not suitable for the old type shale courts. They did however suggest ISS Dressings but said they have not had contact with them for over a year. They would be interested in knowing if we find a supplier.
