Erosion Solutions
Elastotite® ROCK GLUE Resilient Erosion Control
Resilient and durable, ROCK GLUE is a highly effective solution for erosion control and slope protection. ROCK GLUE is an open-pored revetment solution that maintains structural integrity and can be used in a variety of applications including drainage channels, culverts, shorelines, rivers, railroad beds, and other embankments.
ROCK GLUE offers significant design flexibilty for integration into natural landscapes. The monolithic, porous structure easily conforms into various shapes and promotes natural re-vegetation.

Lower cost for construction and maintenance
-
Seamless integration into environment
-
Restores flora and fauna; protecting neighboring habitats

A Structurally Stable Solution
ROCK GLUE binds aggregate to generate an open porous structure that dissipates water energy, thereby reducing the impact of breaking waves and heavy flows. The permeable design allows for expansion and contraction of water, eliminating damage from freeze-thaw cycles. A proven resilient solution, ROCK GLUE can withstand extreme weather events including heavy floods and typhoons.

ROCK GLUE technology
- The porous structure between the stones withstands heavy wave impact.
- The cover layer also offers a habitat for flora and fauna.

Conventional technology
- Rigid concrete structures can be broken down by wave impact, frost and ground subsidence.
Typical Applications
ROCK GLUE can be used for many different applications, including:
- Coastline
- Riverine
- High flow areas
- Highway drainage
- Railroads
- Golf courses
- Mining
- Stormwater management
- Rain gardens
- Culverts
- Green roofs
Design

ROCK GLUE revetments are resilient erosion control solutions. To ensure the structure performs to BASF's highest standards, it is required that the design follows a comprehensive set of guidelines for design, construction, and maintenance.

Installation Process
Construction of ROCK GLUE revetments can be completed using traditional lightweight construction equipment. The following images are a schematic of ROCK GLUE installation.
Step 1: Slope preparation
Step 2: Spreading of geotextile

Step 3: Mix ROCK GLUE resin and isocyanate

Step 4: Add ROCK GLUE to the clean, dry aggregate

Step 5: Coating aggregate with ROCK GLUE by tumbling
Step 6: Place ROCK GLUE covered aggregate
Step 7: Level ROCK GLUE covered aggregate
Step 8: Completed ROCK GLUE reventment
Environmental
Extensive studies have been completed on ROCK GLUE with various aquatic organisms and water chemistry environments.
ROCK GLUE revetments can provide ecological benefits by acting as habitat for biological colonization, allowing fast ecological recovery of local flora and fauna. Both labortory and field research has shown that ROCK GLUE is readily colonized by micro-algae. The open pore structure of the composite creates an attractve habitat for vegetation and other organisms such as snails and macroinvertebrates.
Both the short-term and long-term effects of ROCK GLUE have been assessed in bioassay studies using various aquatic organisms including zebrafish, algae, soil nematodes, daphnia (water fleas), chironmids (midges or lake flies), and pseudomonas bacteria. Both hardened and unhardened ROCK GLUE were analyzed and has been shown to cause no adverse effects to the aquatic environment.
Sustainability
Sustainability studies of ROCK GLUE were conducted using three main criteria; eco-effiiency, building materials and waste, and cost effectiveness.

An eco-efficiency analysis was completed on ROCK GLUE used to calculate ecological impact over its life cycle. The analysis compared an installation of ROCK GLUE revetment versus other traditionalerosion protection solutions. ROCK GLUE had a lower ecological impact in 5 of the 6 categories measured. ROCK GLUE uses renewable raw materials in its composition.
