The fastening category covers very different scenarios: anchoring geosynthetics to the ground in civil works, sealing and securing geomembranes in hydraulic works, holding down nets and artificial turf in landscaping, bundling cables in electrical installations or closing bags in the agri-food industry. Choosing the right fastener determines whether the hold will last for years or fail in the first rainy season. This comparison of the eleven Dodom fastening references helps you decide which one fits each task.

What to consider before choosing
Before buying, assess these four criteria. They determine whether the fastener will do the job or fail in the first season of rain or real use.
- Material to fasten and type of surface: geosynthetic to the ground (plastic pin, staple + washer), geocell to the ground temporarily (fiberglass rod + anchor cap), residential artificial turf (plastic pin or staple with washer), cables in an installation (cable tie), industrial bag (thread), geocell against geocell (connector), geomembrane to concrete (Poly Lock), sealing geomembrane overlaps without welding (adhesive), HDPE repair or welding (rod). Each material has its specific fastener.
- Required mechanical strength: the temporary fastening of geocell on a slope or wall while it is being spread and filled is solved with a fiberglass rod and anchor cap; holding down residential artificial turf works well with a plastic pin or a thin metal staple with a washer; bundling cables requires a cable tie with a self-locking ratchet. Oversizing wastes money; undersizing produces failures.
- Environmental exposure (UV, humidity, salinity): the UV-stabilized plastic pin, the UV-stable black cable tie, the geocell connector, the washer, the HDPE rod and the Poly Lock are calibrated for the Caribbean sun. The metal staple remains buried or covered by the geosynthetic, which reduces its exposure to active corrosion; the fiberglass rod, for its part, is immune to corrosion and does not rust.
- Quick operation or auditable professional installation: quick residential installation: plastic pin or staple with washer (one hand + mallet). Auditable professional installation: fiberglass rod with cap, geocell connector, Poly Lock, adhesive and HDPE welding rod. The difference is between light landscaping and civil or hydraulic works with structural responsibility.

The fiberglass rod and the anchor cap appear as separate rows because they are sold separately, but on site they work as a single temporary geocell fastening system. Likewise, the metal staple performs better on delicate nets when combined with the distributing washer.

Before buying, define two things: what you need to fasten or seal (geosynthetic, cable, bag, geomembrane, turf) and the mechanical demand of the project. The practical rule: light residential landscaping → plastic pin or staple with washer; civil works with geocell on a slope → fiberglass rod + anchor cap for temporary fastening + connector between panels; hydraulic works → hot-melt adhesive to seal without welding, HDPE welding rod when thermofusion equipment is available and Poly Lock to anchor the geomembrane to concrete; bag closing → industrial thread; electrical installation → tairra. Each fastener has its scenario and is not interchangeable.
Do not use a plastic cable tie (tairra) as a geocell connector. The tairra lacks the calibrated geometric design needed to maintain the mechanical confinement of the geocell under load, and it breaks or loosens over time, compromising the system. Conversely, do not use a residential plastic pin to fasten geocell on a slope: without the fiberglass rod + anchor cap combination, the geocell does not stay in position while it is being spread and filled.

Frequently asked questions
Can I use a tairra (plastic cable tie) to join geocells?
It is not recommended. The tairra is designed to bind cables and bunches, not to maintain the mechanical confinement of a geocell system under load. The specific geocell connector has a geometric design calibrated to the panel slots and resists tension and shear, conditions that the tairra does not withstand in the long term.
When do I use hot-melt adhesive and when do I use HDPE welding rod?
Hot-melt adhesive seals overlaps, joints and patches of geomembrane when wedge or extrusion welding equipment cannot be brought to the site: it melts in its own bucket with an electric heater and creates a joint with permeability equivalent to that of the sheet. The HDPE welding rod, on the other hand, requires a manual extruder or a heat gun and a trained operator, and creates a monolithic bond for repairs and structural welds. If you have thermofusion equipment, use the rod; if not, the adhesive.
Does the fiberglass rod rust under the geosynthetic?
No. The rod is made of fiberglass, a material immune to corrosion that does not rust, not even in coastal areas with high salinity. It is also lightweight and non-conductive, and the cap covers the top cut. Its function is the temporary fastening of the geocell while it is being spread and filled, and it is reusable as long as it does not splinter; it can only splinter if struck violently.
