Measure the full surface and sides to be covered, then allow additional material for overlap, slope and secure fixing. Do not rely only on the footprint because height and fastening points consume part of the sheet.
Secure Sheeting for Storage and Site Protection
Tarpaulins provide temporary cover for materials, equipment and work areas exposed to dust or weather. MacBlair stocks them as part of the site equipment range. Sheet dimensions, material weight, eyelet spacing, expected exposure and the shape being covered should guide selection rather than nominal size alone. Check the finished dimensions where the manufacturer distinguishes cut size from usable size.
Allow enough material to overlap the protected area and form a slope that sheds water. Avoid flat pockets where rain can collect and stretch the sheet under concentrated load. Use several fixing points to spread tension, adding compatible ropes or straps without pulling individual eyelets excessively. Pad sharp corners that could cut or abrade the material. Do not drag the sheet across masonry or metal edges during placement.
Tarpaulins must be secured for the forecast conditions and checked after wind or heavy rain. A loose sheet can flap, tear or become a hazard to people and traffic. Do not attach sheeting to temporary site fencing or scaffolding unless the temporary works design accounts for the significant extra wind loading. Re-tension loose areas from ground level where possible instead of climbing onto a covered load.
Ventilation may be needed where covered materials can retain moisture or where condensation could damage the load. Keep Tarpaulins away from flames, hot work and sharp moving equipment unless the product is specifically rated for that exposure. Clean and dry the sheet before folding, inspect eyelets and seams, and store it away from rodents, oils and cutting tools. Small tears should be dealt with early before wind enlarges them.
Tarpaulins FAQs
Create a clear slope and support broad spans so rain can run off. Recheck tension after rainfall, as stretched material can form pockets that collect more water and overload fixings.
Spread load across several fixing points, use compatible ties and avoid relying on one eyelet or loose weights. The fixing structure must withstand the expected load, and the cover should be inspected when conditions change.
Only when the temporary works design allows for the extra wind load. Adding a sheet can turn an open structure into a sail and greatly increase forces on ties, couplers, panels and feet.
Clean off debris, allow the sheet to dry fully and fold it without sharp creases around dirty fittings. Store it away from heat, oils, rodents and sharp tools, and repair damage only by an approved method.
