OUR PROVEN PROCESS
How We Complete Your Groundworks & Retaining Walls – Step by Step
Step 1: Free Site Survey, Assessment & Quote
We visit your property to assess your groundworks requirements.
Whether you need drainage solutions, land leveling, retaining walls, or excavation work, we'll survey the site comprehensively – measuring slopes and levels, checking soil conditions and water issues, assessing drainage needs, and discussing solutions.
We'll explain what's structurally and practically feasible, advise on drainage engineering (crucial for longevity), and design groundworks solutions that solve your specific problems.
Within 2-3 days, you'll receive a comprehensive quote with all work clearly itemised.
Step 2: Excavation & Groundwork Preparation
Once you're happy with the quote and a start date is booked, we begin the groundworks.
Our team excavates as required – whether that's drainage trenches, foundation depths, site leveling, or retaining wall bases.
We remove unsuitable materials, dispose of all waste, and protect your property throughout.
Proper groundwork preparation is critical for long-term success.
We excavate to correct depths, install drainage systems where needed (pipes, French drains, soakaways), compact sub-bases properly, and create foundations that prevent settlement.
Good groundworks are what ensure everything built on top lasts 20-50+ years without problems.
Step 3: Installation & Construction
We then complete the specific work – installing retaining walls with proper drainage behind them, laying drainage pipes and connecting to soakaways, leveling and compacting ground for patios or lawns, or whatever groundworks your project requires.
William works on-site with the team, ensuring structural integrity and quality at every stage.
For retaining walls specifically, we install comprehensive drainage behind walls (perforated pipes, drainage aggregate, geotextile fabric) to prevent water buildup.
We backfill with free-draining materials, not clay soil. This engineering is what separates groundworks that last decades from those that fail within years.
Step 4: Finishing & Handover
We complete your groundworks with appropriate finishing – capping retaining walls, leveling disturbed ground, connecting drainage to outlets, and ensuring everything functions correctly.
We tidy all areas, remove waste, and conduct thorough quality checks.
We walkthrough the completed work, explain any maintenance requirements, answer all questions, and ensure you're completely satisfied with how we've solved your garden challenges.
You receive your 6-year guarantee documentation.

Frequently Asked Questions

How do you fix a waterlogged garden?
The solution depends on the cause. Most waterlogged gardens need proper drainage systems – French drains (gravel-filled trenches with perforated pipes) directed to soakaways or drainage outlets. For severe cases, we install land drainage across the affected area. Clay soil often needs more extensive drainage than sandy soil. We assess your specific situation and design the appropriate solution during site survey.
How high can retaining walls be built?
Walls up to 1m can generally be built as standard garden walls. Walls 1-1.5m require careful engineering with proper foundations and drainage. Walls over 1.5m often need structural engineer calculations and may require building regulations approval. We'll advise on what's feasible and compliant for your situation.
Do retaining walls need planning permission?
Generally no for garden retaining walls under 1m. Walls over 1m, near boundaries, or affecting drainage may need permission. Building regulations may apply for walls over 1.2m retaining significant soil loads. We'll guide you through any requirements during consultation.
Why is drainage so important for retaining walls?
Water accumulating behind retaining walls creates enormous pressure (hydrostatic pressure) that pushes walls forward and causes failure. Proper drainage – perforated pipes, free-draining aggregate, and weep holes – prevents water buildup and is absolutely essential for longevity. It's the difference between walls lasting 30 years or failing within 5.
Can retaining walls be used for raised beds?
Absolutely – retaining walls create perfect raised beds for planting. This adds both function and beauty. We can incorporate planting pockets, different height levels for visual interest, and drainage that works for both the wall structure and the plants.
How much does it cost to level garden ground?
Land leveling costs depend on area size and how much soil needs moving. Small areas (20-30m²) typically cost £500-£1,200. Medium areas (50-80m²) cost £1,200-£2,500. Larger areas cost more. If significant soil needs removing (lowering ground level), disposal costs add to the total. If you're raising levels, topsoil needs importing. We provide accurate quotes after site assessment.
How long do retaining walls last?
With proper construction and drainage, brick and stone walls last 100+ years. Railway sleepers last 20-30 years (treated softwood) or 50+ years (oak). Concrete block walls last 50+ years. Gabions last 30+ years. Poor drainage dramatically reduces these lifespans – proper installation is crucial.
Will tree roots damage retaining walls?
Tree roots can potentially damage retaining walls over time, especially brick or stone walls with mortar joints. We assess any nearby trees during survey and advise on safe distances or root barriers if needed. Generally, keeping large trees 5-10m away prevents issues.
Can I build retaining walls myself?
Small sleeper walls (600mm high) are feasible DIY projects for skilled homeowners. Anything higher requires structural knowledge, proper foundation work, and comprehensive drainage engineering. Poor DIY retaining walls often fail within 5 years due to inadequate foundations or drainage. Professional installation provides peace of mind and longevity.
