Our Retaining Wall Services

Concrete Retaining Walls

  • Poured-in-Place Walls Toronto: Engineered cast-in-place walls using reinforced concrete to withstand heavy loads and hydrostatic pressure. Ideal for high-load or commercial applications.
  • Segmental Block Walls GTA: Interlocking concrete block systems (e.g., Allan Block, Versa-Lok) with integrated drainage and geogrid reinforcement for up to 8 ft of height without mortar.
  • Timber & Natural Stone Walls Toronto: Rustic, eco-friendly solutions using treated timber or local stone for low-height, garden-style retaining walls.

Design & Engineering

  • Site Grading & Soil Analysis: Comprehensive site survey to determine soil type, slope angle, and water table—critical factors for wall height and drainage design.
  • Drainage Solutions: Install perforated drain pipes, gravel backfill and geotextile filter fabric to prevent hydrostatic pressure behind walls.
  • CAD Renderings & 3D Models: Visualize your retaining wall’s appearance and integrate steps, planters or lighting—ensuring aesthetic harmony with your landscape.

Repair & Maintenance

  • Retaining Wall Repair Toronto: Fix bulging, bowing, or settling walls by regrading, adding reinforcement plates, or partial rebuilds.
  • Weep Hole & Drain Repair GTA: Clear clogged drain pipes, install new perforated pipes, and add drainage rock to relieve water pressure. 
  • Re-seating & Re-leveling: Lowered soil levels or erosion can cause walls to lean—our technicians re-level footings and reinstall capstones for safety.

Why Choose Valencia LCD

Structural Engineering Expertise

We collaborate with licensed structural engineers to certify wall designs that meet Ontario Building Code for load, height and drainage requirements.

High-Quality Materials

Use CSA-approved concrete blocks, high-strength poured concrete mixes, or regionally sourced natural stone for durability in Toronto’s freeze-thaw conditions.

Transparent Pricing & Warranty

Our Retaining Wall Toronto quotes include excavation, materials, geogrid installation, drainage piping, backfill and finishes—backed by a 2-year workmanship warranty.

Complete Site Restoration

After wall installation, we regrade surrounding soil, refill planting beds, and can install turf or ground cover to prevent erosion—leaving your property neat and usable.

Our Process

Our Process 

1. Free Site Consultation & Quote

• Arrange a no-cost inspection within 48 hours. We measure slope, note existing vegetation and observe drainage patterns.

• Provide a detailed proposal listing “Concrete Retaining Walls Toronto,” “Segmental Block Walls GTA,” “Timber Wall Installation” and associated costs.

2. Design & Permitting

• Produce CAD drawings showing wall height, grade lines, backfill material and drainage details.

• We obtain necessary permits (City of Toronto Grading Permits, Mississauga Building Permits), ensuring compliance and no delays.

3. Excavation & Footing Preparation

• Excavate to the required depth for a stable footing (typically below frost line).

• Pour footing for concrete walls or compact a gravel base for block walls—strive for 98% proctor density.

4. Wall Construction & Drainage

• Concrete Walls: Build formwork, place rebar cages, pour concrete, strip forms after curing, then parge walls with waterproof coating.

• Block Walls: Lay first course level, install geogrid layers every 2–3 courses, incorporate drain pipe and gravel behind blocks for soil relief.

• Natural Stone & Timber: Install treated posts or secure socketed stone bases, backfill with drainage rock, and pack soil carefully.

5. Backfill, Grading & Finishing

• Place free-draining gravel behind walls, compact in lifts, then backfill topsoil to original grade.

• Grade surrounding area to direct runoff away from the wall face.

• Install capstones on block or concrete walls and finish stone walls with mortar or dry-stack finish per design.

6. Final Inspection & Cleanup

• Check for proper alignment, level top course, and confirm drain pipe discharge location.

• Remove formwork (concrete) or stakes (block) and clean workspace.

• Provide maintenance guidelines: inspect weep holes annually and seal block walls every 3–5 years in GTA’s freeze-thaw cycle.

Frequently Asked Questions

Do I need a permit for a retaining wall in Toronto?

Yes. Any retaining wall over 1.2 m (4 ft) requires a Grading Permit from the City of Toronto. Valencia LCD handles the application and drawings.

Which is better: segmental block vs. poured concrete wall?
  • Segmental Block Walls: Faster to install, flexible, cost-effective for walls up to 8 ft tall, suitable for most residential projects. 
  • Poured Concrete Walls: Stronger for higher-load applications and commercial sites; better when soil pressure is extreme. We recommend based on final height, load requirements and budget.
How do you prevent drainage issues behind retaining walls?

We install a perforated drain pipe (weeping tile) at the base, backfill with free- draining gravel, and include weep holes or drainage mesh. Proper grading above the wall directs surface water away.

Can I add lights or landscaping features to my retaining wall?
Absolutely. We can integrate LED step lights, decorative capstone lighting, or planters into the wall design. Ask us about hardscape lighting options for increased curb appeal.
