Weed Mat, GeoMat & Geotextile for Landscaping & Ground Preparation

Bare ground rarely stays bare for long, making the layer underneath a landscape an important part of preparing the area properly. Rally | Ground Covers brings together weed mat, GeoMat, geotextile & 150mm weed mat pins for compatible landscaping, garden, ground-separation & outdoor preparation work.

Different fabrics solve different problems, so width alone shouldn't decide the purchase. Black weed mat & GeoMat options support compatible ground-covering & weed-management applications, while grey geotextile provides another material choice for suitable separation & drainage work.

For finishing landscape boundaries around compatible installations, explore Rally Edgings. Rally Garden Tools also covers equipment for preparing & maintaining surrounding garden areas.

What Are Rally | Ground Covers?

Landscape fabric creates a functional layer between prepared ground & the materials, planting or construction detail above it. Rally | Ground Covers includes several related products rather than one universal fabric for every outdoor application.

The collection includes:

► Rally Weed Mat for compatible weed-suppression & landscaping applications
► Rally GeoMat for compatible ground-cover & weed-management applications
► Rally Geotextile for compatible ground separation, landscaping & drainage applications
► 150mm Weed Mat Pins for securing compatible fabric during installation

Understanding the intended role of each material is more useful than treating every roll as interchangeable.

Why Choose Rally | Ground Covers?

A narrow garden strip, broad landscaped bed & drainage installation can require completely different fabric dimensions. Multiple widths, roll lengths & material types allow buyers to select around the actual ground area rather than adapting one format to every project.

Weed Mat for Landscaping

Persistent weed growth can quickly increase maintenance across an otherwise finished landscape. Rally Weed Mat provides a physical ground-cover layer for compatible garden & landscaping applications.

Rally woven weed mat is specified as 85gsm woven polypropylene, UV stabilised & manufactured using 100% recycled materials. Its supplier also specifies high water & air permeability.

GeoMat for Ground Coverage

Broad areas become easier to plan when the roll width matches the footprint. Rally GeoMat provides another black ground-cover format for compatible weed-management & landscaping work.

Current collection sizes include:

► 1.2m x 10m
► 1m x 50m
► 2m x 50m

Geotextile for Separation & Drainage Applications

Some ground-preparation jobs need a separation layer rather than simply a weed-management layer. Rally's grey geotextile range provides options for compatible landscaping, ground-separation & drainage applications.

Current sizes include:

► 1.2m x 10m
► 600mm x 50m
► 1m x 50m
► 1.2m x 50m
► 2m x 50m

Pins for Holding Fabric in Position

Even correctly selected fabric needs to remain positioned while the surrounding landscape is completed. Rally 150mm Weed Mat Pins are available in 20-piece & 200-piece quantities for securing compatible weed mat & ground-cover installations.

What's Available in Rally | Ground Covers?

Width determines how many runs may be needed, while roll length determines how far each run can continue before another section is required.

Weed Mat Sizes

Small garden jobs don't need to begin with a 50m roll, while larger landscaping areas can quickly consume short lengths. Rally Weed Mat includes compact formats for limited areas plus longer rolls for broader installations.

Current options include:

► 910mm x 10m
► 910mm x 25m
► 910mm x 50m
► 1830mm x 5m
► 1830mm x 10m
► 1830mm x 25m
► 1830mm x 50m
► 3660mm x 50m

Comparing both roll width & total length helps reduce unnecessary joins, excessive offcuts & shortages during installation.

Weed Mat vs Geotextile

Two rolls can appear similar before installation while performing different roles once they're placed in the ground system.

Weed Mat

Weed-management projects call for a material selected around the landscape above it. Weed mat is the more relevant starting point where compatible weed suppression beneath landscaped areas is the primary objective.

Its role is to provide a physical layer across prepared ground while allowing the installation to accommodate planting positions, edges & suitable surface materials.

Geotextile

Ground separation introduces a different requirement from controlling unwanted growth. Rally's grey geotextile becomes relevant where compatible separation, landscaping or drainage applications form part of the project.

Rather than choosing geotextile simply because it appears more technical, match the material to the construction detail underneath the finished surface.

GeoMat

Another black ground-cover option can be useful where the dimensions better suit the site. Rally GeoMat provides alternative formats for compatible landscaping & weed-management applications.

Where project documentation specifies a particular fabric type, drainage characteristic or construction detail, follow that requirement rather than substituting materials purely because their dimensions are similar.

Common Applications

The finished landscape gets the attention, but the layer underneath can influence maintenance, separation & how the area is put together.

Compatible applications can include:

► Garden-bed preparation
► Landscaping projects
► Weed-management areas
► Decorative pebble installations
► Mulched garden areas
► Property maintenance
► Nursery & horticultural work
► Ground separation
► Compatible drainage installations
► Paths & landscaped zones where the selected fabric suits the construction

For a decorative surface above compatible landscape fabric, Rally | Pebbles provides stone options across multiple colours, sizes & pack quantities.

How to Choose the Right Roll Width?

Every unnecessary seam creates another section that needs positioning, overlap & securing. Matching roll width to the shape of the area can make material planning considerably more efficient.

Consider:

► Total area width
► Total area length
► Number of runs required
► Planned overlap
► Curves & irregular boundaries
► Planting openings
► Edges requiring trimming
► Obstacles within the area

A wider roll can reduce longitudinal joins across broad spaces, while a narrower format may produce less offcut around paths, strips & restricted areas.

How Much Ground Cover Do You Need?

A square-metre calculation gives you the starting quantity, not necessarily the final quantity to order.

Calculate the basic area as:

Area = Length x Width

Then allow additional material for:

► Overlapping adjoining runs
► Edge trimming
► Curved boundaries
► Planting cuts
► Obstacles
► Changes in direction
► Installation allowance

Irregular areas can be divided into smaller rectangles before the areas are combined. This makes the initial estimate easier to check before allowing for overlaps & cuts.

Prepare the Ground Before Laying Fabric

Once the finished surface goes down, fixing poor preparation underneath becomes considerably harder. Prepare the ground for the intended application before rolling out the fabric.

Depending on the project, preparation may include:

► Removing existing weeds & unwanted growth
► Clearing sharp debris
► Removing objects that could damage the fabric
► Establishing the required ground profile
► Addressing drainage requirements
► Checking finished levels
► Planning planting positions
► Confirming boundaries & edging

The appropriate preparation changes depending on whether the fabric is being used for landscaping, weed management, separation or another compatible ground application.

Installing Weed Mat Around Plants

A few minutes spent mapping plant positions can prevent unnecessary cutting across the fabric later. Plan the layout before making openings for new or existing plants.

Oversized openings expose more ground than required, while openings that are too restrictive may interfere with the intended planting arrangement.

Existing plants deserve particular care. Avoid unnecessarily constricting stems, trunks or established growth with the fabric.

Plan Overlaps at Joins

A join that looks neat during installation can still become a weak point if adjoining runs move apart later. Where multiple runs are required, provide suitable overlap for the specific fabric, ground conditions & finished covering system.

Avoid assuming one universal overlap measurement applies to every material or application unless the manufacturer or project specification provides one.

Pins can help hold compatible fabric in position during installation, particularly around joins, boundaries & other areas where movement needs to be controlled.

Secure the Fabric Before Finishing

A gust of wind can turn a loose sheet into a much harder installation within seconds. Position the fabric carefully & secure it progressively rather than leaving a large area unsecured.

Rally's 150mm Weed Mat Pins provide a compatible fixing option within the collection.

Available quantities include:

► 20-piece pack for smaller requirements
► 200-piece carton for larger landscaping installations

The quantity required will vary with fabric dimensions, joins, boundaries, ground conditions, layout & exposure.

Adding Pebbles, Mulch or Other Finishes

Ground cover is usually one layer of a larger landscaping system rather than the visible finish itself. Depending on the design, compatible surface treatments may include decorative stone, suitable mulch or other specified landscaping materials.

Surface material shouldn't be expected to correct poor preparation underneath. Ground profile, drainage, fabric positioning, joins & edge detailing deserve attention before the final covering is placed.

Keeping the finished area defined can also reduce migration of loose landscaping materials. Rally Edgings provides complementary options for compatible landscape boundaries.

Water Movement Still Matters

Managing weeds doesn't mean preventing water from reaching the ground should become the objective. Rally woven weed mat is specified as having high water & air permeability, allowing both to move through the material.

Overall drainage performance still depends on the complete installation.

Soil conditions, slope, sub-base, surrounding materials, drainage infrastructure & the finished surface can all influence where water travels.

Where separation or drainage is the primary requirement, assess whether Rally's grey geotextile better suits the project detail.

Think Beyond Installation Day

A finished garden bed still needs ongoing maintenance once the fabric disappears beneath the surface. Planting, watering, edging & surface-material maintenance continue after the ground cover is installed.

Where watering equipment is also part of the landscape setup, Rally Garden Hoses provides a complementary option for compatible garden & property watering requirements.

Keeping access to planting areas in mind before installing fabric can make later maintenance less disruptive.

Expert Tips

Choose the Fabric Before the Roll Size

A perfectly sized roll of the wrong material still leaves you with the wrong product. Decide whether the job calls for weed mat, GeoMat or geotextile before comparing dimensions.

Map the Area Into Runs

Roll width becomes easier to compare once the site is divided into installation strips. Plan where joins are likely to fall before calculating the total material requirement.

Allow for Installation Waste

Exact square-metre calculations rarely survive every curve, cut & overlap. Include sensible allowance for the real layout rather than ordering only to the theoretical area.

Clear Sharp Debris

Damage underneath the fabric can begin before the landscape is finished. Remove sharp objects & unsuitable debris while the ground remains exposed.

Secure as You Work

A partly installed roll is easier to control than an entire loose sheet. Position, align & secure compatible fabric progressively.

Keep Plant Openings Controlled

Large unnecessary cuts expose more ground around every planting position. Size openings around the actual planting requirement.

Inspect Before Covering the Fabric

Pebbles or mulch can hide folds, open joins & missed sections surprisingly well. Check alignment, overlaps, fixing points & exposed ground before adding the finished surface.
