What this SWMS covers
Geofabric installation is a specialised landscaping and civil works activity involving the placement of permeable geotextile fabrics to achieve various engineering and horticultural objectives. These synthetic fabrics, manufactured from polypropylene, polyester, or polyethylene materials, provide soil stabilisation by reinforcing weak subgrades, weed suppression by blocking light penetration whilst allowing water and air movement, drainage enhancement through filtration of sediment whilst permitting water flow, and separation between dissimilar soil or aggregate materials preventing intermixing that compromises structural performance. Geofabrics range from lightweight woven materials used for garden bed weed suppression to heavy-duty non-woven needle-punched geotextiles specified for road construction and erosion control applications. Construction projects utilise geofabrics across diverse applications including beneath paved surfaces where fabric separates road base from subgrade preventing aggregate migration into soft soils, on slopes for erosion control where fabric stabilises soil whilst vegetation establishes, under synthetic grass installations where fabric provides weed barrier and drainage enhancement, in garden beds for long-term weed suppression reducing maintenance requirements, beneath decking and paved areas preventing weed growth through surface gaps, in drainage systems as filter fabric around perforated pipes preventing sediment ingress, and in retaining wall construction for drainage and soil separation functions. Each application requires appropriate fabric specification considering factors including required tensile strength, permeability characteristics, ultraviolet resistance for exposed applications, and longevity expectations. Geofabric products are supplied in rolls of varying widths typically ranging from 1.8m to 5.4m with lengths from 50m to 300m depending on fabric type and application. Roll weights vary substantially from approximately 15kg for lightweight woven garden fabrics in short rolls to over 300kg for heavy-duty civil engineering geotextiles in full-length rolls. This weight variation creates significant manual handling considerations requiring assessment of handling methods, mechanical aids, and team lifting protocols for heavy rolls. Installation typically requires ground preparation including vegetation removal, soil levelling or grading, removal of sharp objects that could puncture fabric, and sometimes light compaction to create stable surface for fabric placement. The installation process involves rolling out fabric across prepared ground, maintaining appropriate overlap between adjacent fabric strips typically 300mm minimum, securing fabric using appropriate fixing methods including steel pins or staples for temporary installation or purpose-designed anchoring systems for permanent applications, cutting fabric to fit around obstacles using sharp knives or scissors, and protecting installed fabric from damage during subsequent construction activities. For weed suppression applications, fabric is often covered with mulch, gravel, or decorative aggregate after installation. For structural applications including road construction or slope stabilisation, fabric placement must achieve specified coverage without wrinkles, folds, or tears that could compromise performance, and installation quality is frequently subject to engineering inspection and approval before covering. Environmental conditions significantly affect geofabric installation work. Wind can lift and displace lightweight fabrics during installation requiring immediate securing of leading edges as fabric unrolls. Hot weather creates heat stress risks for workers performing physical labour on exposed sites often with dark-coloured geofabric absorbing and radiating additional heat. Wet conditions make fabric slippery creating slip hazards and can compromise adhesion of some securing methods. Installation on slopes introduces additional fall risks and makes fabric handling more difficult as gravity pulls material downhill. Workers must coordinate carefully when handling large rolls as loss of control on slopes could result in rolls running downhill causing crush injuries to workers or damage to structures in the roll path.
