Hi,
I had part of my garden landscaped by an unprofessional landscaper, so now wary, I'm trying to put together a reasonable specification for a new landscaper I hope to employ to do the rest of the work.
The design is quite complicated: natural stone slabs surrounded by clay pavers in a repeating pattern; a circle kit of natural stone over a manhole cover surrounded by radial clay pavers; and a large patio of natural stone slabs with clay paver detailing around the inner edge.
Below is the spec I've written for the paving with brick detailing. I wasn't sure how much excavating it was essential or reasonable to request, or how to specify the amount of sand/cement mixture that needs to go under the bricks and slabs above the sub-base - but as it's only a patio and path (which doesn't carry much weight) I haven't gone for the full monty. I was confused about whether the bricks need to be pointed as well as the slabs - hoping they wouldn't because of the cost of all that pointing! (The slabs are 30mm thick and the clay pavers are 50mm deep).
Paving with brick detailing: Excavate to reduced depth of at least 175mm below finished level (325mm below dpc) and remove spoil, in areas shown on the attached scale plan. Excavate any soft spots in sub-grade as required and dispose. Supply, lay and compact minimum of 100mm of DTp1 crushed stone sub-base material to falls and levels. Supply and lay in areas shown on the plan 25mm zone 2 sand bed, 200x100x50mm clay pavers to falls and levels. Include all cuts and sealing of joints with silica jointing sand. Blocks to be Blockleys Hadley Red Mixture or Chelmer Valley Riviera. Supply and lay on 45mm grit sand/cement bed, Stonemarket Trustone Glenmoor slabs in sizes indicated on plan. Point joints with sand and resin mortar. Where the bricks/slabs meet the house or garage walls, ensure brick and slab paving slopes away from the walls to avoid rain water pooling against the walls. Clear site of all debris and rubble on completion and make good.
Is this good enough? Do the bricks need to be pointed as well as the slabs? Have I asked for the right amount of sand/cement bedding?
Any comments gratefully received.
