Hi Mark, Keith & team,

I just wanted to extend my appreciation for the fantastic week we all had at Holowiliena Station.

I have learnt a great deal and I think you will all agree all the guys worked very hard to achieve completion in the 4 days.

Many times Frances commented that she thought she had won the lottery when we all turned up!!!!!!!

I have attached a pdf of images that I have taken for your information if needed.

Can I also add that If you have any small projects that come up & you are looking for trades, that you could consider me available.

Many thanks once again.

If you are passionate about restoring and maintaining our country’s historic stone buildings and are looking to gain valuable skills and potentially expand your business, I highly recommend you attend one of the many workshops run by Keith McAllister, director of Applied Building Conservation Training.  Earlier this year I had the opportunity to work on the heritage listed Cantara homestead in the heart of the Coorong.  Keith’s knowledge of stonemasonry, lime mortar technology, and salt damp remediation acquired from working on historic sites in Australia and abroad is vast.  He is passionate and committed to share his expertise with others so that these tried and tested methods are not lost to future generations.  A rewarding and enjoyable hands on learning experience which could as it has for me open up new doors and job prospects.  5 stars

“After the completion of our first ABCT training course we took our previous and new skills and undertook the complete restoration of the old boot makers shop at Sevenhill, Clare Valley, South Australia. The old shop is a four main room solid stone construction building that dates back to 1850 and well worth restoration. A business was established and other maintenance projects have been undertaken at locations such as Martindale Hall but the main task remains the boot makers shop restoration which is expected to take the best part of three years as it is a complete gut and rebuild. We have undertaken two more ABCT course since the first one. All have been well run professional courses that have greatly added to our knowledge of traditional stone masonry and heritage restoration techniques. We look forward to completing more ABCT courses in the future to further improve our knowledge and to take on other projects to preserve the State’s stone heritage once the restoration of the old boot makers is complete.”

Dear Keith
I want to say thank you for such a well run workshop this Saturday.
I did not know what to expect but found it tremendously interesting.
I loved being hands on as well.
Up until today I have been partially sceptical as to lime mortar without cement.
But your course showed that lime is not simply lime and so using the hydraulic lime in the correct consistency and moisture truly works and works so well.
Rest assured in all my heritage work I will be a dedicated advocate of the Lime Technology.
Soon I am to skin render off a heritage stone wall in Willunga then repoint it. When I have skinned it, I would like it if you could come out to and give me some pointers on the right technique to repoint it.
Rest assured there will be plenty of Tea and Cake.
I have spent some time with Andrew Stevens the Heritage Architect discussing Lime verses Cement mortars.
My interest in your technique is because I have watched poor work done on my church walls with cement mortar and the stone has severely fretted away leaving the mortar sitting bold and catching water running down the wall.
Part of the problem in the industry has been the compliance specifications for mortars in general which call for a certain consistency of cement. However if I have a heritage Architect prepared to sign off on a strict lime mortar then the Bricky or stone mason can rest at ease.
As Promised
I have attached a link to the Nu-lok slate roofing system.
The tech info does not show the track system very well, but their video gives a better understanding.
I also have a sample section of the track and joining sleeve with a sleeve of welsh slate
The photos of the stone repair work has been done with 3 sand to 1 lime to 1/4 cement.
I will seriously look into your other courses especially the extended ones.
