HEIGER Retaining Pins are built for reliability and strength, designed specifically to secure erosion control products like blankets, weed mats, coir logs, and geotextile meshes. Made from galvanized steel, these U-shaped pins feature sharpened ends for easy insertion and firm grip across a range of soil types. With a U-width of 30mm and steel thickness of 3.15mm, they provide excellent holding power while resisting corrosion and rust even in harsh outdoor conditions.
Available in three lengths—150mm, 200mm, and 300mm—our pins are suitable for both soft and compacted soils. Supplied in boxes of 500, they’re perfect for large-scale landscaping, construction, and civil works projects.
Whether you’re installing biodegradable coir logs on a sloped riverbank or laying down weed mats in a garden, HEIGER’s retaining pins ensure your materials stay securely in place.
Need help choosing the right pin length?
Shorter pins (150mm) are best for firm, dense soil conditions, while longer lengths (200mm or 300mm) offer greater anchorage in loose or sandy soils.
Installation Made Simple
Just position your mat, mesh, or log and push the pin down until it sits flush with the surface. No tools required in most cases. For tougher ground, a mallet may help with easier placement.
Applications of Retaining Pins
Erosion Control Installations
Secure coir logs, jute mats, or erosion blankets along riverbanks, slopes, and construction sites.
Landscaping Projects
Hold down weed mats and mulch films in gardens, parks, and roadside green zones.
Soil Stabilisation
Fix geotextiles or mesh on loose, unstable terrain to prevent soil movement during heavy rainfall.
Revegetation Support
Keep plant covers or biodegradable mesh in place to aid native plant growth in restoration zones.
Drainage and Civil Infrastructure
Reinforce drainage blankets and sediment control systems around roads and culverts.

FAQs About Retaining Pins / Weed Mat Pins
What are retaining pins used for?
Retaining pins, also known as landscape staples or ground anchors, are primarily used to secure materials like erosion control blankets, weed mats, coir logs, and geotextile fabrics to the ground. Their U-shaped design ensures stability, preventing materials from shifting due to wind, water flow, or foot traffic.
How many pins do I need for my project?
Retaining pins commonly come in lengths of 150mm, 200mm, and 300mm. The appropriate size depends on soil conditions:
150mm: Suitable for hard or compacted soils.
200mm: Ideal for medium-density soils.
300mm: Best for loose or sandy soils where deeper anchoring is necessary.
The standard U-width is typically around 30mm, providing a secure grip on the material being anchored.
How many pins do I need for my project?
The number of pins required depends on the material and installation area:
For erosion control blankets or weed mats, it's recommended to place pins every 0.5 to 1 meter along the edges and at overlaps.
Allow for additional pins at overlaps and seams to ensure stability.
For example, for a 10-meter-long blanket, you might need approximately 20 to 40 pins, depending on the spacing and site conditions.
Can retaining pins be reused?
Yes, if the pins are made from durable materials like galvanized steel and are not bent or damaged during removal, they can be reused. However, repeated use may dull the sharp ends, making insertion into the ground more difficult over time.
Are retaining pins suitable for all soil types?
Retaining pins are versatile and can be used in various soil types. However, their effectiveness depends on the soil's density:
In hard or compacted soils, shorter pins (150mm) are effective.
In loose or sandy soils, longer pins (300mm) provide better anchoring.
For extremely rocky or challenging terrains, specialized anchoring solutions may be more appropriate.
Do I need any tools to install retaining pins?
In softer soils, retaining pins can often be inserted by hand. For harder or compacted soils, using a rubber mallet can help drive the pins into the ground more easily and ensure they are flush with the surface.
Are galvanized retaining pins better than non-galvanized ones?
Yes, galvanized retaining pins are coated to resist rust and corrosion, making them more durable and suitable for long-term outdoor use. Non-galvanized pins may corrode over time, especially in moist environments, reducing their effectiveness and lifespan.
Can I use retaining pins for artificial turf installation?
Absolutely. Retaining pins are commonly used to secure artificial turf, ensuring it stays in place and maintains a smooth, even surface. They help prevent movement due to foot traffic or environmental factors.
How should I dispose of retaining pins after use?
If the pins are still in good condition, consider reusing them for future projects. If disposal is necessary, check with local recycling programs to see if they accept metal items. Avoid leaving pins in the ground, as they can pose hazards to people and equipment.
