Is this way of setting up the level strings ok?
 
Hi Everyone,

I removed all the grasses... now I need to setup the strings and start to remove the real soil to a correct depth... read quite a few ways to setup those levelling strings.... here is somthing I kind of combine different methods and would like to share with you and may be some expect here can point out anything wrong on this method:

as my to be laid area is kind of a irregular levelled ground with an irregular shape (not rectangle)... so this is the scheme I come up with and think it should work:

1. I surround the area with sticks and join each sticks with a string and make sure the string is levelled. All strings are at same height levelwise speaking, so the end result of this step is a surrounded levelled strings. I keep these setup untouch.

2. for places I require 1/4" / feet slope I measure up the distance from the strings in step 1 and drop accordingly and hammer in new sticks and tie in new strings.

3. for places I want to follow the natural grade, I setup sticks with the exact same height expose up the ground and joint them with strings.... to find the exact length expose... I can use the step 1 measurement to find the shortest expose stick for the direction I am interested in.

4. for places I want 100% level, I would use the height found in step1 to hammer in new sticks and tie new strings.

after step 2, 3 and 4 I should have all the horizontal and vertical grid strings which I can be used to guide how depth I should shovel by making a mark on my shoveler...

I have done step 1 yesterday... and will do step 2 and 3 as next steps... then hopefully, this weekend can do the real digging....


Above discuss levelling on one area... in my case, I actually have multiple areas which join together buy I want them have grade changes at the joining area sharper rather than gradually... I intend to use multiple surrounded levelled enclosed area and repeat above process to do that.

Will this work?....


Thanks for answering...

It sounds like your idea would work. How large of an area are you dealing with? My two concern would be the time it took you to lay all of this out, someone may hit a grade stake and your yard would look like a giant spider web and it would be difficult to work around the strings and stakes. Have you considered a contractor to get you to grade or getting a laser level?
As far as following the natural grade, just eyeball it.

thanks and
 
Thanks for your comment... I really appreciate it... as this is the first time for me stuff.

I actually will dig one area at a time (ie. one enclosed loop) ... rather than the whole backyard...

the whole project is approx may be 1000 sq. ft.... I intend to divid it into 3 areas because of the grade situation....

I know that when the stick and string come off, it would be a total waste of my effort...

that is why I told my wife that the kids are probhabit to the backyard until further notice and I hope Toronto weather will be nice for a few days at least...

regarding contractors... it is kind of expensive for me... and I want to save $$ to buy a better stones...

using a lazer level.... I didn't think of that even I got a couple of those equipments.... I was using line level all along... may be next loop I will give that a try...


Thanks a lot

I'm glad you're not doing the entire 1000 ft² all at one time. A few things to consider. Plan for your downspout water. Are you going to install an irrigation system or hardwired landscape lights? Now would be the time to rough them in. If you are not using a natural product, you may also want to order all of your stones and have them all delivered at the same time. Manufacturers sometimes change their product line. I would also look for a source other than the box stores to get your stones. You can sometimes get a break on the quantity and the delivery from a real supplier.
I know contractors cost, but sometimes the savings in time and saving your back is well worth it, especially with the short summer. Good luck and be sure to post pictures.

thanks again
 
to be honest and excuse me... I do not know what is a irrigation system and what its for... may be I will search the web a bit for that and see if I need to do it... regarding wiring and stuff.. I will pass on that... thanks for remind me taking pictures... will do... some before/after...

I have a hidden reason that I didn't share with my wife... why not hiring contractors... besides $$... you can't get the satisfaction when friends come to your place and they find out you did the stones yourself....for that it is really money can't buy....

I am kind of the margin of my age being able to do this stuff myself... few more years I amn't sure about that...

yes I did find a great landscape special store... all kind of people going there including lots of contractors....

Regarding place the order now... I am a bit hestiate... as I am not sure when will be ready for what stage... I am even thinking of placing double delivery charges having the materials deliver to me multiple times... in order for those stuff not to seat on the front yard for too long... you know... but I probably end up go for all at one shot...when I getting more confidence/closer to the stage.

ok, just find out what is irrigation system... I probably don't need those in Toronto... I suppose those thing are for desert type places... may be I am wrong... but here we worry about too much water underground more than too little water for wetting the basement....

I think you missed my point. I would hire a contractor to grade your yard only. With the multiple levels you will need a proper base and they would get it done in no time. They could also bring in/remove fill. You would do all of the finish/stone work.

that still quite expensive
 
consider preparing the base is really I think 80% of the job... although I never asked... but I wouldn't surprise contractors will charge a lot here... you have to know in Toronto... or in Canada... for this sake... everything is real expensive.... if you know it cost nowaday almost half a million for a decent home here...
