Understanding Concrete Floor Services

Concrete floor services encompass three main categories: leveling (preparing uneven surfaces), grinding (removing coatings and smoothing), and polishing (creating glossy, finished floors). Whether you're preparing for tile installation or creating a polished concrete finish, professional concrete services are essential for Vancouver residential and commercial properties.

Why Concrete Floor Services Matter

Foundation for tile: Proper leveling prevents tile failure and lippage
Cost-effective flooring: Polished concrete eliminates need for other materials
Durability: Professional finishes last 20+ years with minimal maintenance
Improved aesthetics: Transforms dull concrete into beautiful floors
Enhanced value: Quality concrete work increases property value
Moisture management: Proper preparation prevents water issues

Types of Concrete Floor Services

1. Concrete Floor Leveling

Leveling creates a flat surface essential for tile installation and other finished flooring.

When Leveling Is Needed

Before tile installation (most critical application)
Uneven floors with dips, slopes, or high spots
After removing old flooring materials
Settling foundations causing floor irregularities
New construction with imperfect concrete pours

Leveling Methods

Self-Leveling Compound

Best for minor irregularities (1/8" to 2")
Flows to create perfectly flat surface
Quick curing (24-48 hours)
Ideal for residential applications
Cost: $3-8 per square foot

Grinding and Patching

Removes high spots by grinding down
Fills low areas with patching compound
More labor-intensive but cost-effective
Best for moderate unevenness
Cost: $2-5 per square foot

New Concrete Overlay

For severely uneven or damaged floors
Pours new concrete layer (1-2")
Most expensive but most effective
Structural repair option
Cost: $8-15 per square foot

2. Concrete Grinding

Grinding removes surface materials and creates smooth, even concrete.

Applications for Concrete Grinding

Removing old adhesives, coatings, and paint
Smoothing rough or broom-finished concrete
Eliminating surface imperfections
Exposing aggregate for decorative looks
Preparing for epoxy coatings or sealers
First step in polished concrete process

Grinding Equipment

Floor grinders: Remove 1/16" to 1/8" per pass
Scarifiers: Aggressive removal of thick coatings
Edge grinders: Access tight corners and edges
Dust extraction: Essential for clean, safe work environment

3. Polished Concrete Floors

Polishing transforms ordinary concrete into a durable, high-gloss finished floor.

Benefits of Polished Concrete

Durability: Extremely hard surface resists wear and damage
Low maintenance: Simple cleaning with microfiber mops
Cost-effective: No need for additional flooring materials
Sustainable: Uses existing concrete, no new materials
Light reflectivity: Glossy surface brightens spaces
Stain resistant: Densifier and sealer protect surface
Longevity: 20+ years with minimal maintenance

Best Applications for Polished Concrete

Commercial spaces: Retail stores, showrooms, offices
Industrial facilities: Warehouses, manufacturing plants
Residential basements: Modern, industrial aesthetic
Garages and workshops: Easy to clean, durable
Restaurants and cafes: Food-safe, easy maintenance

The Polished Concrete Process

Step 1: Surface Preparation

Proper preparation ensures successful polishing:

Remove all coatings, adhesives, and contaminants
Repair cracks and damage
Grind surface to expose concrete
Test moisture levels (must be below 3 lbs/1000 sq ft)
Identify and fill voids

Step 2: Initial Grinding (Coarse Diamonds)

First grinding passes remove surface material:

30-40 grit metal-bond diamonds
Removes up to 1/8" of surface
Exposes aggregate if desired
Creates profile for densifier penetration
Multiple passes for even results

Step 3: Densification

Chemical hardener strengthens concrete:

Apply liquid densifier (lithium or sodium silicate)
Penetrates concrete pores
Chemical reaction creates calcium silicate hydrate
Hardens surface by 25-40%
Reduces dusting and porosity
Allow proper drying time (24 hours minimum)

Step 4: Progressive Grinding (Medium to Fine Grits)

Multiple passes with increasingly fine diamonds:

80 grit resin-bond pass (removes scratches)
150 grit pass (refines surface)
400 grit pass (begins polishing process)
Each pass removes previous scratches
Vacuum and clean between passes

Step 5: Final Polishing (High Grit)

Achieve desired gloss level:

800 grit for satin finish
1500 grit for semi-gloss
3000+ grit for high-gloss mirror finish
Each level increases reflectivity
Commercial spaces typically use 800-1500 grit

Step 6: Sealing and Protection

Final protection enhances appearance and durability:

Apply penetrating sealer for stain resistance
Optional topical sealer for added protection
Guard treatment for enhanced maintenance
Allow full curing before use (7 days typical)

Concrete Leveling for Tile Installation

Why Leveling Matters for Tile

Tile installation requires extremely flat surfaces to prevent:

Lippage: Edges of tiles at different heights
Cracking: Tiles break when not fully supported
Grout failure: Uneven stress causes grout to crack
Aesthetic issues: Uneven floors look unprofessional
Water pooling: Low spots collect water

Industry Standards for Tile Underlayment

Different tile types require different flatness:

Standard tiles (12x12" or smaller): 1/8" variance over 10 feet
Large format tiles (15x15" or larger): 1/16" variance over 10 feet
Extra-large tiles (24x24"+): 1/8" variance over 10 feet in any direction

Professional Floor Leveling Process

Step 1: Assessment and Measurement

Use laser level or long straightedge
Identify all high and low spots
Measure variance across entire floor
Calculate material requirements

Step 2: Surface Preparation

Clean floor thoroughly (remove all dirt, oil, paint)
Grind or scarify if contaminated
Repair cracks and structural damage
Apply primer to improve adhesion

Step 3: Leveling Compound Application

Mix self-leveling compound per manufacturer specs
Pour in strategic locations
Spread with gauge rake to approximate thickness
Allow compound to flow and self-level
Use spike roller to release air bubbles
Maintain consistent temperature during curing

Step 4: Verification and Preparation for Tile

Verify flatness after curing (24-48 hours)
Sand high spots if needed
Clean surface for tile adhesion
Ready for tile installation

Common Issues and Solutions

Concrete Floor Problems

Cracking

Cause: Settlement, thermal expansion, structural issues
Solution: Fill with epoxy or polyurethane, install crack isolation membrane

Moisture Issues

Cause: Hydrostatic pressure, poor drainage, no vapor barrier
Solution: Moisture mitigation systems, proper drainage, epoxy moisture barriers
Critical for tile: Must resolve before tile installation

Spalling and Pitting

Cause: Freeze-thaw cycles, poor concrete quality, chemical exposure
Solution: Grind away damaged areas, patch with repair mortar, seal properly

Dusting

Cause: Weak surface concrete
Solution: Apply densifier, grind and polish, or apply coating
