Dear Jeff,
Julie & I just want to say thank you for the help and consultation in regards to our
Outdoor gardens, Fountain, Brick Pavers, Sandstone Stair-Cases around our property.
Over the past 4,6 years, we have seen a lot of aging and growth of Green Moss, that starts to turn into a permanent Black stain that settles into most of our Masonry surfaces here, and no matter how often I Pressure wash and clean each of these surfaces, it just seems to be going Darker and Darker in Colour and we have lost that New, clean look you get when it’s first laid or installed.
And the constant rework and cleaning start to absorb any free time you may have in mind, while the property just seems to be aging before your own eyes are very frustrating to stay on top of, and to date I have had no solutions to these issues.
As I stated, I was already on my way to the Hardware shop, to try and find a Product solution at the same time I approached you on your Face book Advert, In regards kind offer to use your Masonry Cleaning & Treatment processes, and also to Use your product MasonProof in that small trial we did, it was amazing.
And now the 3 stages are complete, I wanted to share these Photos & Pictures with you and I’ll let them do the talking from here, Enjoy.






2 years ago, June 2018, All the Sandstone retainer walls The Blocks in this Picture were Pressure washed.

Upon a follow-up Inspection today 12th June 2020,
It is amazing the retention of the Vibrant colours and how clean the Sand-Stone Blocks still are today.







Hi Jeff and GTS team,
I wanted to write to you and thank you for your assistance with rejuvenating our sandstone blocks used in retaining around our home, as you know they had become discolored and begun to stain black.
The blocks have been installed for 3-4 years as we had them done in 2 stages, with the oldest walls showing the worst of the black mould on them.
We had previously tried a sealant available from Bunnings but found that it wasn’t making much of a difference to the wear and appearance of the sandstone in the sections we had applied it to test its efficacy.
In late 2018 we heard through word of mouth about GES and after chatting with you about the blocks, we had a look at MasonProof on your website and decided we would have a small section pressure washed and treated with MasonProof as a trial while pressure washing other blocks to compare.
12 months later we were pleased to see that the section tested had remained mould free and water still visibly beads on the surface of the blocks. This is in contrast to the remaining walls which continued to blacken and stain.
After chatting to you again we decided to proceed to have the remaining walls cleaned and treated with MasonProof in June 2020 and are so far happy with the results, again water is beading off the sandstone and they look as new again,
Some points worth noting
– We noticed that after the pressure wash, some slight dark stain still remained on the worst affected areas, but overall, very close to looking like new.
– After the MasonProof treatment, we saw an improvement in the ‘brightness’ of the stone colour from the dullness due to mould covering/stains.
– While we realize there is still some cleaning and maintenance required, after seeing the effects of the trial area we did, we are convinced the time between washes and ease of washing will be much more economical.
– Some grass die-back happened around the base of some blocks but has grown back without issue.
Everything was done as promised and on time, no mess was left, and no complaints from us at any point either when we had the trial applied or the remaining blocks treated.
I would definitely apply MasonProof at time of installation of the blocks if we had the time again.

Thanks again

Before & After, MasonProof Treatment (Below)



Jeff & the GTS/GESA Team,
here are a bunch of Before and After Photos that I promised from today 26 July 2020,
Following The final stage of our Clean-up & MasonProof treatment.
And what an amazing job, We actually thought all the Black Mould stain was going to be trapped inside
our sandstone for ever, Its been an amazing transformation & well worth the extra investment to finally
preserve our sandstone and lower the painful rework we have been doing over the last few years.
We can’t thank you guys enough, for all the help & great advice along the way,

Soil Erosion Magazine: Dust Control

dust control orovilleIt was February when the problems started. Just north of Sacramento, nestled among outdoor recreation areas, the Oroville Dam started falling apart. The world’s tallest dam’s main spillway partially collapsed; dam managers started using an emergency spillway that sent water down a bare hillside, which quickly eroded. As 200,000 people were evacuated downstream with more rain on the way, a problem with dust probably wasn’t on the minds of the folks at the California Department of Water Resources (DWR).

But on March 16, the Los Angeles Times reported that air and soil analysis at the Oroville dam site, where debris was being removed, revealed one of the most dreaded airborne particulates out there: cancer-causing asbestos. Naturallyoccurring asbestos is not uncommon in California, but still, the state was obliged to produce dust-control measures, to protect workers at the site and residents in the area who may be affected. News releases from the dWR indicated that they were using water, at least at first, to keep the dust down. Methods included wetting the soil with water trucks and things like washing the trucks and truck tires on the vehicles used at the site.
