Retaining Walls
For Safer, Usable Levels

Turn a Difficult Slope
Into Level, Usable Space

Cooksey builds garden and retaining walls for homeowners in Barry and nearby South Wales areas, creating safer levels and usable space with drainage considered from the outset.

Level Space for Seating or Lawn

Hold back sloping ground to create space the household can actually use.

Safer Routes Between Levels

Combine retained levels and well-placed steps for more confident movement.

Raised Beds With Clear Structure

Shape planting areas without allowing banks of soil to dominate the layout.

Drainage Behind the Wall

Use suitable backfill and drainage to reduce the load created after heavy rain.

Choose the Right Wall
for the Ground It Retains

The retained height, available space and surrounding materials all influence which type of garden wall is suitable for the site.

Block Retaining Walls

Create defined levels with blockwork planned around height, nearby surfaces and how the garden will be used.

Timber Sleeper Walls

Use timber sleepers for retaining features, raised beds or stepped planting.

Raised Walls That Add Usable Planting Space

Build accessible planting areas that define zones, add depth and reduce work at ground level.

Replace Cracked or Leaning Walls From the Foundation

Remove a leaning wall, identify the cause and rebuild with suitable support, drainage and level connections.

Retained height, soil, access, and water movement determine the structure required. These factors matter more than the visible material alone.

Retaining Walls Need
Structure and Drainage

What Changes the Cost of a Garden Wall?

Garden wall costs depend on length, retained height, excavation, access, materials, foundations and drainage. A site assessment allows the required construction to be priced properly.

Which Foundations Suit the Ground and Wall Height?

Soft soil, roots, buried obstructions and previous structures can affect excavation and support. The existing ground needs assessing before the foundations are specified.

How Do Backfill and Drainage Reduce Water Pressure?

The amount of ground held back influences the wall thickness, foundations and drainage required. Larger level changes may also need specialist structural input.

When Is an Engineer or Planning Permission Needed?

Walls beside a highway or above certain heights can require consent, and planning limits for fences, gates and garden walls may affect the design before work begins.

Levels and Drainage
Shape the Wall Design

Cooksey considers retained height, soil, access and water movement before work is scoped, so the wall suits the pressure behind it and the space around it.

See What Better Ground Levels Make Possible

A landscape gardening project in Barry combined retaining work, sandstone paving, and fresh turf to turn a difficult slope into flatter, more practical areas.

Garden and Retaining Wall FAQs

Practical answers about pricing, wall types and drainage before changing the levels within your garden.

Start With the Height and What Lies Behind It

A site visit allows the slope, retained ground, access and surrounding features to be assessed before the wall is specified.

How much does a garden wall cost?

The cost depends on the wall’s length, retained height, excavation, access, foundations, materials, and drainage. A low wall around a raised bed requires different preparation from a structure holding back a substantial slope, so the site must be assessed before an accurate written quotation can be prepared.

The right construction depends on how much ground needs retaining, the soil, available space and the appearance you prefer. Blockwork may suit more substantial level changes, while timber sleepers can work for lower retained areas, raised beds or stepped planting where the expected load is appropriate.

Drainage is often needed where a wall holds back soil, because water collecting behind it can increase pressure and affect the retained ground. The suitable approach depends on the wall, soil and surrounding levels, but water movement should be considered before construction begins.

Cooksey Landscape Gardening did a fantastic job on my garden. It was an absolute jungle before, and they have completely transformed it. They removed all the trees, bushes, and the pond, levelled the entire area, and then laid new grass along with building a back wall. The difference is amazing. The team were lovely to work with, very professional, and completed everything in such a short time. I would highly recommend them to anyone looking to transform their garden.
