A quick question for the landscape fraternity. Is it common practice to instal a perforated plastic land drain under block paving? A client has a garge built into a hillside, the rear of which is backfilled with stone. At the base a land-drain was laid which runs around to the front corner and then under the block paving and towards the sewers. After eight years the drain is blocked under the paving and water is now being forced upwards between the blocks. This water is mainly near a mature sycamore ( positioned within the paved area) but there is also a 10-15 yr old cypress hedge close by, another individual cypress and a climbing hydrangea growing up the front wall of the house. I'm no expert, but I think this is poorly designed and the run under the paving shouldn't have been perforated. Could the contractor have thought that surface water would perculate through the paving into the land drain to be moved away? Would that be a normal practice or consideration? :confused1:

Is there room to mulch below the canopy to improve the rooting environment?

Thought it was the carb at fault? Least it was that you were blaming last week! :lol:

They were giving The Sun away, FOC, in a garage I stopped in the other week, and still no takers.

Does anyone actually accept responsibility for their own stupidity anymore?

So you're bucking the trend of Brexit and leaving Europe? A quick question, do you have any knowledge on the longevity of the birch pollards. Near enough every one I've ever climbed has been decayed and falling apart. Looking at the photo's, there's going to be some pretty large wounds some time in the future. Do you think yours are 'out of cycle' or are they allowed to get that large a diameter normally?

I thought this was a British landscape thread? Just saying:001_tt2:

From my reading on Trimbles website I actually understand this:thumbup1: I'm off to play with my I-phone to see how I get on. Ideally, in the not too distant future, I could do with sorting all this out properly, the tablet isn't ideal or quick for data collection and it's a lot of un-necessary work correlating everything into the report again. Thank you kindly

That's what the engineers said, cost of steel, two milled keyways, two threaded holes at one end and profiled/trued up - They could do a hundred at that cost - one off - forget it.

Ouch! We got a new shaft for the ST6 recently, £100 + Vat. With bearings being £60-70 it seemed daft not to replace at the same time. Compared to the time and effort of dismantling parts are pretty cheap, so the job might as well be done right to start with. Speaking to the engineering shop next door, they said they couldn't make one for the cost of buying one or in the time that Forst could supply (Next day)

You can lease Keysofts tree mapping quarterly (PM me if you want the figure) and the results are good - shadows, RPA's, RPA intrusions etc and not too difficult to learn (I have )

That's simple? I didn't even know that you could show gps co-ordinates on a photo. Is that on a camera or a phone? Technology is a black hole to me, I learn to do what I need but that's about it.

Which GPS though? I had a garmin years ago for walking and the level of accuracy left a bit to be desired. Saying that I did read last night that Clinton passed a bill around 2000 to take the inbuilt inaccuracies out of the system. Fascinating stuff when you start to learn how it all works. This has all arisen due to a management survey with a lot of trees in close proximity. I could just tag each tree, but I'd like to try to map them for the future to assist the clients ongoing management policies. Thanks for the suggestion. I wonder at the accuracy of the gps on my i-phone:confused1:

Came across this thread while searching 'GPS tree surveying equipment' so I thought I'd bump this rather than starting a new one. I'm currently using Keysofts Keytree LT, which I like and works well with imported DWG topo's. Tree positions are marked so it's simple to import the tree data (from an excel file) from a tablet I take on site. (an android asus thing with the detachable keyboard - not ruggetized sp?) Until now this has sufficed. Now I'm looking to accurately locate tree positions with a gps/Gis device and I'm totally lost. I did attend a seminar about this last year but I was more focused on the software and CAD stuff. I think I can get as far as importing an OS map of a site and then identifying the co-ordinates of a position on it to 'set' the plan - so if I can get the co-ords of the trees it should be plain sailing I've spent a few hours researching and am now confused about things like firmware, operating systems of different devices and incompatibilities. I haven't got a huge budget but don't need an all singing all dancing device, just a means of accurately locating the tree location. Would something like this do or am I completely off track?

The first word that came into my mind too:thumbup1:

I think social media has enhanced public perception that the consumer is king, that businesses are at the beck and call of the man with the money. Some of the demands of customers are becoming unbelievable because some believe that we're only here for their benefit and we can't survive without their £100 job.

Elm? Can't see enough to guess at which one.

Why would you even broadcast that? You'd think that would have ended upon the cutting room floor.

Thanks for posting.

Some years ago a HSE fella landed on a site, fresh from a two week course on the arb industry. Proudly announcing that he was Manchesters H&S man over tree workers he procede to inspect and question everything. With only one 'climber' on site he jumped on the absence of a rescue climber. When we said that the owner was there as a rescuer, tickets were mentioned. I said that I'd trained him, we practiced regularly and I was confident in his ability. Wasn't that as good, or better, than someone with a ticket who hadn't climbed since gaining it. Short answer was, it would be better with a ticket, to cover ourselves. For some reason he refused to give an opinion or a definitive answer.

Is their first slot between 8AM and 1PM though?

and don't wear sandals?

Vat and helpline don't really go together do they?

Garden shears! Arborists use silky's don't they?
