Scotia Grass Installation Method
- Dig out old lawn, we like to excavate most jobs using our micro digger to a depth of 100-150 mm as required.
- Install treated timbers to suitable level, using timber stakes firmly on the side of the timbers fix using screws.
- Fill and spread type 1 stone approx 1 ton to every 8-10 m2 Compact using heavy whacker compactor plate. This creates a solid base, prevents sinking and allows natural drainage.In Scotland a stone base is a must due to our high rain fall. Beware of installation guides that only use 1 layer of sand these are for hot dry weather countries.
(Beware many companies are not putting this layer in to save time and money failure to put an adequate sub base can lead to surface dipping over time, poor drainage and pooling water)
- Spread concrete sand or whin dust over sub base approx 1 ton to 12-14 m2 .compact using a compactor plate, we then screed the sand to create a firm base.
- To prevent weeds penetrating the drainage holes we lay a lotrak high quality membrane nailed in place to timbers. This is important an part of the process
- Roll out the grass ,we then cut it to size, using joining tape and artificial grass adhesive we connect and glue down joins. We then use galvanized nails to fix grass to timbers
- If required add a small quantity of kiln dried sand, using a automated brush to bring out the yarn. Job don
Improper Installation methods can lead to poor drainage, pooling water, odours and surface subsidence.
In the last month I have been asked to rectify 3 jobs in Glasgow carried out by 2 large companies in the market, In all cases they had been poorly dug out but most importantly a stone type 1 sub-base had not been installed, instead only 1 layer of concrete sand leading to poor drainage and water pooling in all 3 cases..Proper excavation and at least 6″ in depth of type 1 stone sub-base compacted is required to ensure natural drainage and hard standing.We use a ton of stone to every 8-10 m2 then a layer of coarse aggregate compacted and screened to finish.
Please read our installation method further down the page it is an ideal guide for any landscaper or diy-er installations
WHY WOULD A COMPANY NOT INSTALL A PROPER SUB-BASE?
To save time and money-
1. Not putting a sub -base means less earth is taken out the garden saving on waste removal and labour.
2. Not paying for stone, saving time on labour not putting it in and compacting it.
3. Instead finishing screed concrete sand/coarse aggregate is spread compacted onto soft earth.
4. Using a turf cutter and 1 layer of sand is on many on websites installation guides the truth is this method is designed for hot weather climates with low rainfall and does not suit our weather.
