What Makes Base
Stand Out
India's first polymer-modified screed binder — mix with Zeorich Basalt aggregate to create a high-strength, crack-resistant floor screed far superior to traditional OPC mortar.
The original polymer-modified screed binder in India — pioneering a better alternative to traditional OPC sand-cement screeds.
Achieves 40–50 N/mm² compressive strength — up to 100% stronger than traditional OPC sand-cement screed mixes.
Polymer network within the matrix prevents shrinkage cracking — reduces the most common cause of screed failure on site.
Faster early strength development vs OPC screed — allows tiling or finishing to begin sooner.
Combined with Zeorich Basalt (recycled aggregate), the complete system is more sustainable than river sand OPC mortar.
Part of the complete Zeorich Screed System — pairs with Basalt, Base HD, SBR admix and Wall Putty.
Factory-controlled production ensures consistent mix quality on every bag — eliminates site mixing variability.
Suitable for residential, commercial and industrial floors before any tile or stone covering.
Technologies
Original PM screed binder — no equivalent existed before Zeorich
Compressive strength up to 50% higher than OPC sand-cement screed
Polymer network prevents shrinkage cracking during cure
Early strength gain allows faster project progression
Where Base Performs
All domestic floor screeds before tile, stone or wood floor laying
Offices, retail, hotels requiring durable flat floor screeds
Warehouses and factories — use with Zeorich Base HD for hardened finish
Levelling and repair of uneven or damaged existing floor screeds
High-rise residential and large commercial developments
Patching and repair of existing damaged floor screeds
How to Use Base
- Standard: 1 part Zeorich Base : 4 parts Zeorich Basalt by weight
- Add 10–20% Zeorich SBR by volume of water for improved performance
- Ensure all components are measured accurately for consistent results
- Do not use river sand — Zeorich Basalt is specifically graded for this system
- Substrate must be clean, sound and free from dust and standing water
- Hack or scarify existing concrete if bond is required
- Prime porous or dusty surfaces before pouring screed
- Install movement joints every 3–5m in large areas
- Add Zeorich Base and Basalt to clean water in drum or paddle mixer
- Mix until homogeneous with no dry pockets
- Add Zeorich SBR admix to mixing water for enhanced performance
- Use within the workability window — do not re-temper with water
- Pour and spread to required depth — minimum 25mm, recommended 40–50mm
- Level and compact using a screed board and tamper
- Float to required finish using steel or wooden float
- Cover with polythene sheeting and cure for minimum 7 days
- Keep moist and covered for minimum 7 days
- Allow full drying before tiling — moisture content below 75% RH
- Tile with Calcibond Flex or Calcibond Advance adhesive
- Do not lay tiles on green or damp screed
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 Zeorich Basalt (not river sand) with Zeorich Base. Mix ratios must be strictly followed — incorrect ratios will compromise screed strength.
