Frequently Asked Questions

Find answers to common questions about our paving stone manufacturing process, installation, and maintenance. We're here to help you make informed decisions.

Our paving stones are manufactured using a blend of Portland cement, natural aggregates, and mineral pigments. The cement provides structural strength and durability, while carefully selected aggregates ensure proper density and resistance to freeze-thaw cycles common in Toronto's climate. We use iron oxide-based pigments that are UV-stable and won't fade over time. Each batch includes specific ratios of sand, gravel, and crushed stone to achieve optimal compressive strength of 8,000 PSI or higher. This composition meets CSA A231.2 standards for precast concrete pavers and ensures your surfaces can withstand heavy foot traffic, vehicle loads, and harsh Canadian weather conditions for decades.

The production cycle for our paving stones typically takes 28 days from mixing to full curing. During the first 24 hours, the concrete sets in molds under controlled temperature and humidity. After demolding, pavers cure for an additional 27 days to reach maximum strength. For standard colors and sizes in stock, delivery to Toronto and surrounding areas usually occurs within 3-5 business days. Custom orders with specific colors, patterns, or dimensions require the full 28-day curing period plus 5-7 days for delivery scheduling. We maintain inventory of popular items to reduce wait times. Orders over 500 square feet receive priority scheduling, and we coordinate delivery times that work with your installation timeline.

Yes, our pavers are specifically engineered for Canadian climates. We maintain a water absorption rate below 5%, which prevents moisture from penetrating the stone and expanding during freeze-thaw cycles. The manufacturing process includes vibration compaction that eliminates air pockets and creates a dense matrix resistant to cracking. Our mix design incorporates air-entraining admixtures that create microscopic air bubbles, allowing trapped water to expand safely without damaging the concrete structure. Testing shows our pavers withstand over 100 freeze-thaw cycles without deterioration. The textured surface provides slip resistance even when covered with ice or snow. Unlike asphalt that cracks in cold temperatures, concrete pavers remain stable and can be individually replaced if damaged by snow removal equipment.

Maintenance requirements are minimal. Sweep the surface regularly to remove debris and prevent staining from organic matter. For general cleaning, use a garden hose or pressure washer set to 1,500-2,000 PSI. Avoid harsh chemicals or deicing salts that can damage the surface over time. Joint sand between pavers may settle after the first year and should be replenished with polymeric sand to prevent weed growth and maintain stability. Apply a penetrating sealer every 2-3 years to enhance color and protect against oil stains, though this is optional. If individual pavers become damaged, they can be removed and replaced without disturbing the surrounding area. In spring, check for any displacement caused by frost heave and reset pavers as needed. This simple routine keeps your paved surfaces looking new for 25-30 years.

We manufacture pavers in multiple dimensions to suit various design needs. Standard sizes include 4x8 inches, 6x6 inches, 6x9 inches, and 12x12 inches, with thicknesses of 60mm for pedestrian areas and 80mm for driveways. Our color palette includes 12 standard options ranging from charcoal and slate gray to terracotta and sandstone beige. Custom colors can be produced for orders exceeding 1,000 square feet. Surface finishes vary from smooth to tumbled and textured, each providing different aesthetic and functional properties. We also produce permeable pavers with wider joints for eco-friendly drainage solutions. Pattern options include herringbone, running bond, basketweave, and circular designs. Our team can provide samples and help you select combinations that complement your property's architecture while meeting functional requirements for your specific application.

About Citaja

Building durable outdoor spaces across Toronto since our establishment. We manufacture concrete pavers that combine functionality with aesthetic appeal for residential and commercial projects.

Paver manufacturing facility in Toronto
Serving Toronto

Citaja started operations in Toronto with a focus on producing concrete pavers for local construction needs. Our facility on Roehampton Avenue houses modern equipment that allows us to maintain consistent production standards. We work with contractors, landscapers, and property developers throughout the Greater Toronto Area.

The company was founded by professionals with backgrounds in concrete technology and construction materials. This technical knowledge influences our production methods and quality control procedures. We test each batch of pavers according to Canadian standards for freeze-thaw resistance and load-bearing capacity.

Our Mission

We manufacture pavers that meet the specific requirements of Canadian climate conditions. Our goal is to provide reliable products for driveways, walkways, patios, and commercial hardscaping projects while maintaining competitive pricing for the Toronto market.

Core Values

⚙️

Quality Production

Each paver undergoes compression testing at 40 MPa minimum strength. We use Portland cement Type GU and aggregates sourced from Ontario quarries to ensure durability in freeze-thaw cycles.

🤝

Client Relations

We provide technical specifications and installation guidelines with every order. Our team assists contractors with project planning and material calculations based on site requirements.

🌱

Environmental Practices

Our production uses permeable paver designs that allow water infiltration. We recycle concrete waste from production into aggregate for new batches, reducing landfill disposal by 30%.

💡

Product Development

We adjust our paver formulations based on field performance data and customer feedback. Recent improvements include enhanced color retention pigments and textured surfaces for better traction.

Quality concrete pavers production

Experience & Expertise

Our production team includes certified concrete technicians and quality control specialists. We manufacture 12 standard paver sizes ranging from 100x100mm to 400x400mm, with thickness options of 60mm for pedestrian areas and 80mm for vehicular traffic. Custom dimensions are available for commercial projects requiring specific modular layouts.

The facility operates with automated batching systems that ensure consistent mix proportions. We maintain inventory of 8 standard colors and can produce custom shades with minimum order quantities. All pavers cure for 28 days before shipment to achieve full compressive strength.
