### Flowability

The product is described as **flowable**, enabling:
- Effective penetration into gaps and voids
- Consistent filling of irregular spaces
- Reduced application difficulty in challenging underwater conditions

### Design Purpose

Conbextra EP935 is engineered as a **precision grouting solution**, offering:
- Reliable performance in specialty applications where standard grouts fail
- Compatibility with submerged conditions throughout the service life
- Suitable alternatives to cementitious grouts in water-critical environments

## Product Classification

Within the Conbextra range, Conbextra EP935 represents the **epoxy grout category**, distinguished from cementitious alternatives by its chemical composition and performance characteristics in moisture-laden environments.
