Precisely graded recycled crushed basalt aggregate — paired with Zeorich Base binder to create India's first eco-friendly polymer-modified screed system.
What Makes Basalt
Stand Out
Precisely graded recycled crushed basalt aggregate — paired with Zeorich Base binder to create India's first eco-friendly polymer-modified screed system.
Made entirely from recycled and reclaimed basalt — contributing to sustainable construction and reducing quarry extraction.
Basalt is harder and denser than river sand — produces a stronger, more abrasion-resistant screed layer.
Carefully graded particle size distribution — ensures consistent mix with Zeorich Base and optimal void filling.
Replaces river sand — reduces pressure on river ecosystems and supports green building certification.
Basalt aggregate produces higher compressive strength vs equivalent OPC river sand mixes.
Specifically developed to work with Zeorich Base binder — not interchangeable with other aggregates.
Factory-produced and quality-tested — eliminates variable quality of site-sourced river sand or quarry dust.
Dense basalt aggregate reduces shrinkage during cure — contributes to Zeorich's crack-resistant performance.

Where Basalt Performs
All domestic floor screeds as part of the Zeorich system
Office and commercial floor screeds before tiling
Industrial and warehouse floors with Zeorich Base
Levelling and renovation work in existing buildings
Projects requiring recycled content and eco credentials
High-rise and large commercial development screeds
How to Use Basalt
- Mix ratio: 4 parts Zeorich Basalt : 1 part Zeorich Base by weight
- Do not substitute with river sand — Basalt is specifically graded for this system
- Add Zeorich SBR to mixing water for enhanced performance
- Measure all components accurately for consistent results
- Store in dry conditions away from moisture
- Keep bags sealed when not in use
- Use within 12 months of manufacture date
- Do not contaminate with other materials
- Add Zeorich Base and Basalt to clean water in drum or paddle mixer
- Mix until fully homogeneous with no dry pockets
- Correct mix will have workable plastic consistency
- Do not add excess water — follow the stated W/P ratio
- Pour and spread mixed screed to required depth
- Level and compact using screed board and tamper
- Float to required surface finish
- Cover and cure for minimum 7 days
- Completed screed should have consistent dark grey colour
- No surface cracking within 48 hours of laying
- Minimum 28-day cure before full loading
- Use BRE screed testing methods if required
Ideal working temperature +5°C to +35°C. Avoid direct sunlight and extreme temperatures during application.
Always ensure the substrate is clean, dry and structurally sound before application.
Lift a tile to verify adhesive coverage — minimum 65% floor, 80% exterior and wet areas.
Mix only what can be used within the pot life. Do not add water to extend working time.
Always use with Zeorich Base binder only — do not use as standalone aggregate or substitute with river sand. Maintain 4:1 ratio strictly.
