for paver joints (0 - 10mm)
EnviroSAND Plus designed specifically for pavers, combines high grade angular joint sand, conforming to the
specifications of the Interlocking Concrete Pavement Institute (ICPI), blended with the plant based binder, Organic-Lock for optimal joint lock-up in segmental paver systems. e.g. - interlocking stone
Organic-Lock is the strongest, Sel-Healing Organic glue on the market. It is made from 100% Naturally Occurring Materials!
Erosion Control: EnviroSAND Plus substantially reduces joint sand loss in paver systems caused by rainfall erosion. When activated by water the Organic-Lock forms an adhesive gel, bonding sand particles together. This gel, physically holds the sand together, while creating a thin film on the surface of the joint whenever it is wet. This film acts as a buffer zone for which the water can travel over, preventing washouts!
Weed Deterrent: By elevating the pH of the system, EnviroSAND Plus naturally creates a toxic environment in which seedlings can�t germinate. Weed growth is therefore, effectively deterred with this natural weed deterrent.
Self-healing and flexible: Because of the organic, swellable gum, EnviroSAND Plus remains completely flexible to withstand thermal movement or settlement of the subbase materials. Unlike other synthetic or "polymeric" materials, (because of its organic binder) EnviroSAND Plus can actually re-heal itself in the paver joint. In conditions where shifting from movement may occur, the onset of water reactivates the gel to heal the sand and mold it back, continually taking the shape of the paver joint.
Lift and Re-lay: Lifting and replacing stones is easy by moistening the joint with water. This creates the needed flexibility to remove a stone, adjust it and replace it where needed. Creating a solid, stable surface that can be easily altered, gives even the beginner the confidence to create.
No Surface Staining: Using the unique 2 stage watering process, surface staining is avoided! Because the organic binder swells immediately when in contact with water, its erosion control properties are active much faster than any other chemical product. By activating the EnviroSAND Plus with a slight mist on installation, the very top layer quickly develops its protective film. This allows for a stronger follow up spray that easily cleans the surface. This is completely unique to Envirobond! Spraying too heavily when using a chemical product, like polymeric sand, results in the leaching of its binders.
ENVIROBOND VS POLYMERIC SAND
So what are the differences between Envirobond and Polymeric Sand?
Made from 100% Naturally Occurring Materials
- -Envirobond uses an ORGANIC binder made from a renewable plant.
- -Polymeric Sand uses a chemical reaction to create its bond.
Self-Healing
- -Envirobond is self-healing each time it is in contact with water.
- The Biological binder swells into a gel each time it gets wet. This allows for complete flexibility using this self-healing process.
- -Polymeric sand activates only once.
- This results in cracking in the jointing material.
Weed Deterrent
- -Envirobond stays in place to prevent seeds from dropping in and developing into nuisance weeds. However, Envirobond also has a natural weed deterrent by elevating the pH to a toxic system preventing seeds from germinating when they do find their way in.
- -Polymeric Sand stays in place by getting hard, thereby deterring weeds.
Strongest when Wet!
- -Envirobond products are strongest when wet.
- The plant glue turns into a gel when in contact with water. This gel creates a thin film on the surface of the joint. The film acts as a buffer zone to allow the water to sheet over, thereby protecting the jointing material from washing out. This puts the Envirobond material into its strongest state whenever it comes across its greatest stress (rainfall erosion).
- -Polymeric sand is strongest when it is hard and dry.
Lift and Re-lay
- -Envirobond products can easily be manipulated in a �lift and re-lay� process.
- -Polymeric sand requires a hammer and chisel method to alter the chemical bond.
Staining
- -Envirobond can be installed using a 2 stage watering method designed to eliminate any staining. By lightly misting the system, Envirobond�s gel activates immediately to create a buffer zone on its surface making it capable of resisting erosion. A heavier spray can then (5 mins after) be used to clean the surface of the segmental system (as well as saturating the remainder of the joint). If installed incorrectly, Envirobond will wash off naturally with time, or a coarse brush with water will help it along.
-Polymeric Sand requires strict attention to detail when installing. It is incredibly important to remove all surface dust prior to watering. Too much watering with Polymeric Sand can wash out the binders, so water cleaning is not recommended. Staining of this kind is very common and also difficult to remove.
