Surveyors Tape Measures

About Surveyors Tape Measures

Surveyors tape measures are specialist measuring tools designed for long-distance measurements in outdoor and large-scale applications. Unlike standard retractable tape measures, these professional-grade instruments typically feature durable fibreglass or steel blades enclosed in robust, weather-resistant cases, allowing accurate measurements over distances of 30 metres or more. They're essential equipment for anyone needing to measure large areas, boundary lines, or extensive linear distances where precision and durability are paramount.

The construction of surveyors tape measures prioritises longevity and reliability in challenging conditions. Fibreglass blades resist moisture, won't conduct electricity, and maintain their accuracy even after prolonged exposure to the elements. The open-reel or enclosed case designs allow for easy winding and unwinding, whilst clear, high-contrast markings ensure measurements remain legible even in poor light conditions or at distance. Many models feature both metric and imperial measurements, with intervals clearly marked at regular centimetre or inch increments.

Professional surveyors tape measures from trusted brands like Draper offer the durability and precision required for site work, surveying, and large-scale measurement tasks. Whether you're measuring building plots, laying out foundations, or conducting land surveys, these tools provide the accuracy and reach that standard tape measures simply cannot deliver.

Jargon Buster

• Fibreglass Blade: A non-metallic measuring tape made from woven glass fibres coated in PVC. Fibreglass blades are non-conductive, moisture-resistant, and won't rust, making them ideal for outdoor use and work near electrical installations.
• Open Reel Design: A tape measure configuration where the blade is visible on the reel rather than enclosed in a case. This design allows for quick deployment and rewinding, though offers less protection from the elements.
• Accuracy Class: The precision rating of a tape measure, typically classified under BS EN standards (such as Class II or Class III). Class II offers higher accuracy, with tolerances of ±1.5mm over 30 metres.
• End Hook/Ring: The metal fitting at the end of the tape blade used to anchor the tape at the starting point. Surveyors tapes often feature reinforced steel hooks or rings to withstand the tension of long measurements.
• Closed Case Design: A fully enclosed housing that protects the tape blade from dirt, moisture, and damage. These designs typically include a winding handle for easier retrieval of long tapes.
• Blade Width: The width of the measuring tape, typically 13mm or wider for surveyors tapes. Wider blades provide better stability and are easier to read at distance, though they're bulkier to store.

How to Choose the Right Surveyors Tape Measures

Length Requirements: Consider the maximum distances you'll typically need to measure. Common lengths include 30m, 50m, and 100m options. For general site work and smaller surveys, a 30m tape is usually sufficient, whilst land surveyors and civil engineers may require 50m or longer for extensive measurements.

Blade Material: Fibreglass blades are the most popular choice for surveyors tape measures due to their non-conductive properties, making them safe for use near overhead power lines or electrical installations. They're also resistant to moisture and won't rust, unlike steel alternatives. For general outdoor work and site measurements, fibreglass offers the best balance of durability and safety.

Case Design: Closed case designs with winding handles offer better protection for the blade and are more comfortable for frequent use over long distances. Open reel designs are lighter and more compact but offer less protection. Consider how often you'll use the tape and the conditions you'll be working in.

Measurement Units: Many surveyors tapes feature dual metric and imperial markings. For UK building work, metric measurements are standard, but having both options can be useful for working with older plans or specifications. Check that markings are clear and easy to read, with regular interval markers throughout the length.

Build Quality: Professional-grade models from established brands like Draper offer superior durability with reinforced end hooks, robust cases, and blades that maintain their shape and markings over time. The initial investment in quality equipment pays dividends through longevity and maintained accuracy.

Portability: Consider how you'll transport the tape measure. Some models include carry handles or shoulder straps for easier transportation around site. Weight becomes a factor with longer tapes, so balance capacity with practicality.

Popular Accessories

• Range Poles: Brightly coloured graduated poles used as sighting targets when measuring long distances or conducting surveys. Essential for accuracy over extended ranges.
• Marking Pins/Arrows: Steel pins used to mark measurement points along the tape, particularly useful when measuring distances that exceed the tape's length.
• Chalk Lines: Complement long-distance measurements by marking straight lines between measured points for setting out work.
• Tool Belts and Holsters: Convenient storage solutions for carrying tape measures and other measuring tools around site.
• Spray Marking Paint: For marking measured points on the ground during site layout and surveying work.
• Protective Cases: Additional storage protection for tapes between jobs, particularly important for maintaining accuracy and extending lifespan.

Safety Information

When using surveyors tape measures, observe these important safety considerations:

Electrical Safety: Always use fibreglass tape measures when working near overhead power lines or electrical installations. Never use steel tapes in these environments as they conduct electricity and pose a serious electrocution risk. Be aware of your surroundings and maintain safe distances from live electrical equipment.

Manual Handling: Longer tapes can be heavy and awkward to carry. Use proper lifting techniques and consider using two people for extended measurements to reduce strain. When rewinding, maintain control of the tape to prevent the end hook whipping back and causing injury.

Site Awareness: When measuring across active construction sites or public areas, ensure the tape doesn't create a trip hazard for others. Use high-visibility tape where available, and consider using warning signs or cones when tapes cross walkways.

Weather Conditions: Strong winds can make handling long tapes difficult and dangerous. In adverse weather, secure the tape properly and consider postponing measurements if conditions compromise safety or accuracy.

Frequently Asked Questions

What's the difference between a surveyors tape measure and a standard tape measure?

Surveyors tape measures are designed for much longer distances, typically 30 metres or more, compared to standard retractable tapes which usually max out at 8 metres. They feature more durable construction, often with fibreglass blades that resist moisture and don't conduct electricity. The open-reel or closed-case design allows for measuring extensive distances that would be impossible with a spring-loaded retractable tape.

Why are fibreglass tape measures preferred for surveying work?

Fibreglass offers several crucial advantages for professional surveying applications. It's non-conductive, making it safe to use near electrical installations and overhead power lines. Unlike steel tapes, fibreglass won't rust when exposed to moisture, and it maintains its dimensional stability across varying temperatures. Fibreglass blades are also lighter than steel equivalents, making them easier to handle over long distances.

How do I maintain accuracy with a surveyors tape measure?

Always clean the blade after use, removing dirt, mud, and moisture before storing. Store the tape in a dry location away from extreme temperatures. Check the end hook regularly for damage or looseness, as this affects measurement accuracy. Avoid kinking or sharply bending the blade, and never allow it to snap back uncontrolled when rewinding. Periodically verify accuracy against a known standard, particularly if the tape has been dropped or subjected to heavy use.

Can I use a surveyors tape measure for building work?

Absolutely. Surveyors tapes are excellent for setting out buildings, measuring foundation dimensions, and any construction task requiring measurements beyond the capacity of standard tape measures. They're particularly useful for site layout, drainage runs, and establishing building lines. The fibreglass construction makes them safe for use on active building sites where electrical installations may be present.

What length of surveyors tape measure do I need?

This depends on your typical applications. For general building site work, garden landscaping, and small surveys, a 30m tape is usually sufficient and remains manageable to handle. Land surveyors, civil engineers, and those working on larger sites typically opt for 50m or 100m lengths. Consider that longer tapes are heavier and more cumbersome, so choose the shortest length that meets your regular requirements rather than buying the longest available.
