How to Lay Artificial Grass: UK Materials List

A typical materials list may include the selected artificial grass, a prepared aggregate base, any specified levelling layer, a membrane if the system calls for one, joining tape and adhesive, edge fixings, and infill where the grass instructions require it. The exact list depends on the product, existing surface, drainage and edge detail. Make the list from the manufacturer’s current guide rather than assuming every installation uses the same sequence or material depth.

The calculator estimates grass strips from the available widths in its UK source and provides optional infill and pin counts from its cited data. It does not estimate aggregate tonnage, membrane quantities, adhesive tubes or sub-base depth. Measure and price those items separately using product coverage and supplier instructions. Include edging, drainage components, tools and disposal only after checking the actual site.

Start by sketching the area and measuring the longest and widest points. Divide an L-shaped lawn into rectangles that meet without overlapping, then record each one separately. Note drains, trees, steps, edges, slopes and fixed features that will not receive grass. Check for buried services before digging and agree finished levels with the property and existing drainage.

Ground preparation differs across products and sites. The cited UK supplier guides describe their own base materials and installation sequences, and some recommend seeking a landscaper’s advice where drainage is poor. Follow the grass maker’s instructions for excavation, compaction, membrane use and edge restraint. A surface take-off cannot diagnose clay soil, waterlogging, an unstable subgrade or a change in level.

The UK width data used by the calculator lists 2 m and 4 m rolls. The best width is the one that covers your layout with a supplier-approved cut plan and pile direction. A wider roll can reduce the number of seams but may create more offcut area or be harder to handle. Compare both orientations on paper before ordering, and confirm maximum order length and whether the supplier cuts to length.

For a simple 4 m by 5 m rectangle, 20 m² is the net area. A single 4 m-wide strip cannot cover the full 5 m dimension, so the layout needs another piece or a different orientation. The calculator estimates area and seams for the entered rectangles; it is not a scale drawing. Add a cut allowance that fits your actual boundaries and keep every piece facing the same direction.

The grass calculator can estimate the roll area to order, seam tape length, infill from the selected kg/m² rate and pins from the entered spacing. Its figures are based on UK product examples in the cited data. Check the exact grass label before using an infill rate: some products need no infill, and others specify their own type and amount. Do not choose a default quantity simply because it appears in a generic list.

The tool counts the perimeter of each rectangle and may count edges that touch another rectangle as exposed, so its pin result can be high for joined shapes. Seam tape and adhesive quantities also depend on the final join plan and product coverage. Use the calculator as a first take-off, then reconcile the result with the supplier’s installation guide and the drawn layout.

A frequent planning error is rotating one piece against the pile direction of another. The result can look different from normal viewing angles even when the seam is straight. Another is ordering the net area without allowing for trimming around curves, borders or drainage covers. Keep the pile arrows aligned on the sketch, number each piece and label cut dimensions before ordering.

Do not skip the product’s ground-preparation instructions or assume artificial grass solves existing drainage problems. Check that the selected base and edge restraint suit the subgrade. Follow adhesive cure time and fixing directions, and keep infill out of the seam where the maker instructs. When soil, falls, drainage or levels are uncertain, ask a qualified landscaper to inspect the site.

Use a marked drawing to reconcile grass cuts, joins, infill and perimeter fixings. The calculator estimates some of these quantities from entered rectangles but cannot see if the shape has obstacles, curved edges or unusable offcuts. Compare its take-off with the grass maker’s current installation instructions before ordering.

Check roll width, pile direction, maximum length, product-specific infill, adhesive cure and fixing method with the supplier. If the site has poor drainage or uncertain levels, arrange professional assessment before removing the existing surface.
