About This Material

Gohare Grooved Limestone

Gohare Grooved Limestone is a structured and textured architectural stone surface developed from Gohare Limestone, designed for projects that require controlled texture, visual depth, and reliable surface performance. Extracted from the well-known quarries of Khorramabad in Lorestan Province, Iran, this natural limestone has been supplied to the international market for more than 75 years and is recognized for its uniform background, consistent quality, and stable technical characteristics.

What Is Gohare Grooved Limestone Finish?

The Gohare Grooved Limestone finish is a secondary mechanical surface treatment where parallel linear channels are precisely cut into the stone surface. The groove spacing, width, and depth can be customized according to architectural design requirements. This process creates a directional surface pattern that enhances both visual identity and functional performance.

  • Creates a clean linear and structured texture
  • Reduces surface reflectivity compared to polished limestone
  • Produces shadow lines that enhance architectural depth
  • Improves surface control in selected applications
  • Provides a modern and rhythmic façade appearance

Unlike smooth finishes such as polished or honed limestone, Gohare Grooved Limestone focuses on structure, rhythm, and light interaction. The linear channels respond to natural lighting conditions and create subtle visual contrast while maintaining the stone’s neutral and balanced color tone.

Color Tone and Natural Appearance

This limestone typically presents a light cream to beige background. Depending on quarry selection and sorting, natural gray fossil patterns may appear with varying intensity. These fossils are part of the natural composition of Gohare Grooved Limestone and provide controlled visual variation while maintaining overall surface uniformity.

Sorting Options

Gohare Grooved Limestone is supplied based on fossil presence rather than quality grading. This classification allows architects to achieve consistent visual results across large architectural surfaces.

  • Low Fossil – clean and highly uniform surface
  • Medium Fossil – balanced natural appearance
  • High Fossil – stronger natural character and visible fossil patterns

Applications of Gohare Grooved Limestone

Due to its structured texture and reliable physical properties, Gohare Grooved Limestone is widely used in modern architecture and interior design. The stone is suitable for projects where visual consistency, depth, and surface structure are required.

  • Interior wall cladding
  • Building façade systems
  • Architectural feature walls
  • Corridor and staircase walls
  • Decorative vertical panels
  • Selected exterior applications with proper sealing

For exterior use, professional sealing and waterproof treatment are recommended to improve long-term durability and maintain the stone’s appearance under environmental exposure.

Production Formats

Karimi Stone produces Gohare Grooved Limestone in various formats to match project specifications and installation requirements:

Production and Quality Control

Negin Sang Karimi (Karimi Stone), as the quarry license holder and direct manufacturer, controls the entire production process of Gohare Grooved Limestone, including extraction, block selection, processing, and packaging. Full quarry control ensures stable supply, consistent sorting, and reliable production capacity for large architectural projects.

The grooving process is executed under controlled factory conditions to maintain precise groove spacing, consistent depth, and surface integrity. Strict quality control procedures are applied from quarry block selection to final packaging, ensuring uniform results across large orders and international shipments.

Technical Limitations

Like most limestone materials, Gohare Grooved Limestone is not recommended for environments with continuous heavy water exposure, such as permanently wet industrial flooring or commercial kitchens. Proper installation, sealing, and maintenance planning are essential for optimal long-term performance.

Slip Rating & Wet Pendulum Guide

A concise overview of P1–P5 slip ratings so you can align each Karimi Stone finish with the right space, moisture level and safety expectation.

OVERVIEW

P1 → P5 safety band
P1 P2 P3 P4 P5
What the Wet Pendulum Test (WPT) tells you
The WPT measures how slippery a surface becomes when wet. Each finish is given a P rating from P1 (higher slip risk) through to P5 (maximum grip). As the number increases, the expected slip resistance also increases.

RATING SCALE SNAPSHOT

From higher slip risk to maximum grip
Each Karimi Stone P icon below is your quick visual code before checking detailed applications.

P1 → P5  Left = smoother | Right = more textured

P1

Dry circulation

Higher slip risk

For dry-only walkways and light traffic areas where water is not expected on the surface.

P2

Light splash

Occasional moisture
Bathrooms, small kitchens and transition areas that see brief, easily managed water.
P3

Everyday wet public

Balanced grip
Entries, amenities, undercover car parks and fresh food retail where wet floors are common.
P4

High exposure

Wet, high traffic
Pool surrounds, communal showers and external ramps under 1:14 where water is constant.
P5

Maximum grip

Highest safety band

Commercial kitchens, covered loading docks and pool ramps or stairs leading into water.

HOW TO READ THIS POPUP

Start with water, movement and consequence
Consider how wet the floor can get, how quickly people move, and how critical a slip could be. Then use the cards below to align each area of your project with a suitable P rating before you select a Karimi Stone finish.

TYPICAL APPLICATIONS

P1 – dry circulation
Higher slip risk when wet

P1
For areas intended to remain dry with controlled walking speeds – such as supermarket aisles, separate shops inside centres or dry lobby and corridor zones.
Retail aisles
Dry-only entries
Light traffic

P2 – light splash
Transitional & semi-wet areas

P2
For spaces where occasional water is expected but quickly managed – like hotel bathrooms, apartment kitchens, laundries and transition zones between wet and dry areas.
Hotel bathrooms
Apartment kitchens
Laundries

P3 – regularly wet public
Balanced everyday grip

P3
Used where wet conditions are common – entries and access ways, toilet facilities in public buildings, undercover car parks and fresh food retail areas.
Public entries
Toilet facilities
Undercover parking

P4 – high exposure
Wet, high traffic environments

P4
Selected for consistently wet and busy areas such as pool surrounds, communal showers, external ramps under 1:14 and service zones behind bars.

Variation reference cards

Near-Zero Variation – V0

Ultra-consistent tone with almost no visible shift between pieces. Ideal for gallery-like, minimal interiors where the surface should visually disappear.

Soft Variation – V1

Delicate, low-contrast changes gently break up the surface. A refined choice for calm kitchens, ensuites, and open-plan living spaces.

Moderate Variation – V2

Balanced, natural movement with visible differences in tone. Adds character and depth while staying easy to style with cabinetry and textiles.

Expressive Variation – V3

Stronger contrast from piece to piece with noticeable light and dark areas. Best when you want the surface to act as a key design feature.

High-Drama Variation – V4

Pronounced shifts in hue and tone, creating a richly patterned, statement finish. Ideal for feature walls, dramatic floors, or high-impact spaces.
