Service Overview
What This Service Covers
What It Is
Patio and landscaping groundworks cover all the below-ground preparation needed before a patio, terrace, decking, or landscaped area can be installed. This includes excavation, levelling, sub-base laying, drainage installation, retaining wall foundations, and step foundations. At Digger T, we handle the critical groundwork phase that determines whether your outdoor space stays level, drains properly, and lasts for decades.
Who It's For
Homeowners investing in new patios, terraces, or garden redesigns. Landscapers who need reliable groundwork preparation for their projects. Property developers installing communal outdoor areas. Commercial clients creating outdoor seating, courtyards, or garden areas.
When You Need It
You need patio and landscaping groundworks when building a new patio or terrace, when an existing patio is sinking or pooling water, when redesigning a garden layout that involves changes to ground levels, when building retaining walls or raised beds that need proper foundations, or when installing decking that requires base preparation and drainage.
Why Professional Help Matters
Patios and landscaped areas fail for the same reason driveways fail — inadequate ground preparation. Paving slabs rock and crack because the sub-base wasn't compacted. Water pools because falls weren't built into the levels. Retaining walls lean and collapse because their foundations weren't adequate. Professional groundwork preparation eliminates these problems at the source. The time and cost invested at this stage saves multiples in repair and replacement later.
Why This Matters
What Happens If You Get This Wrong
Outdoor spaces that aren't built on proper groundwork deteriorate faster than almost any other part of your property. Weather, ground movement, and water damage work relentlessly against surfaces laid on poor foundations.
- !Paving slabs that rock, tilt, and crack within one winter because the sub-base was thin, uncompacted, or missing entirely — turning your patio into an eyesore and trip hazard.
- !Standing water that pools on the patio surface after every rain because falls weren't calculated and drainage wasn't installed — creating algae, ice hazards, and staining.
- !Retaining walls that lean, crack, and eventually collapse because their foundations weren't deep enough or didn't include adequate drainage behind the wall.
- !Ground levels that direct water towards your house instead of away from it, causing rising damp, foundation damage, and interior water ingress.
- !Decking subframes that rot prematurely because the ground beneath wasn't prepared with proper drainage and ventilation, requiring complete replacement within 5–7 years.
- !Thousands spent on premium paving, stone, or porcelain tiles — all wasted because the preparation beneath them was inadequate.
Our Process
How We Deliver Results
Site Survey & Level Assessment
We survey your garden, assess existing ground conditions, check drainage routes, and measure levels relative to your property's DPC. We discuss the design, agree on finished levels, and provide a detailed quote.
Excavation & Formation
We excavate to the required depth, removing topsoil, vegetation, and existing surfaces. The formation is levelled and compacted, with correct falls built in for drainage.
Drainage Installation
Surface water drainage is installed to prevent ponding. This may include channel drains, land drains, or connection to existing drainage systems. Retaining wall drainage (weep holes, backfill drainage) is installed where required.
Sub-Base & Edge Restraints
Type 1 MOT sub-base is laid in layers and compacted. Edge restraints are installed to contain the patio surface. Foundations for retaining walls and steps are poured to specification.
Surface Preparation & Handover
The prepared base is levelled to the correct falls and finished to suit the chosen surface material. The site is handed over clean, level, and ready for paving, slabbing, or decking installation.
Benefits
What You Get When You Choose Digger T
Level, Stable Surfaces
Correct sub-base preparation prevents the sinking, rocking, and tilting that ruins patios. Your paving stays flat and functional.
Proper Water Management
Falls and drainage are designed to move water away from your property and off the patio surface. No ponding, no flooding, no damp.
Long-Term Durability
Patios built on proper groundwork last 20+ years without major maintenance. The sub-base protects the surface material from ground movement.
Correct Levels Relative to DPC
We ensure finished patio levels are at least 150mm below your property's damp-proof course, preventing moisture bridging and damp problems.
Strong Retaining Wall Foundations
Retaining walls carry significant loads. We build foundations that account for soil pressure, water pressure, and surcharge loading.
Works With Any Surface Material
Our groundwork preparation suits all surface types — natural stone, porcelain, concrete paving, block paving, and composite decking.
In-Depth Guide
Everything You Need to Know
Sub-Base Preparation for Different Surfaces
Natural stone and porcelain paving require a compacted Type 1 sub-base (minimum 100mm) followed by a full mortar bed. The sub-base must be level and compacted in layers. Any unevenness in the base translates directly to the finished surface — and with premium materials costing £50–£100+ per square metre, this isn't where you want to cut corners.
Block paving uses a compacted Type 1 sub-base topped with sharp sand, similar to driveways. Concrete paving slabs can be laid on a sand-cement mix on compacted sub-base. Each surface type has specific sub-base requirements, and we adjust our preparation accordingly.
Drainage Design for Outdoor Spaces
Every patio must drain surface water away from the property. We design falls of at least 1:60 (approximately 17mm per metre) away from the house. For larger patios, additional fall may be needed to reach drainage channels or permeable areas.
Drainage solutions include linear channel drains at the patio edge, permeable jointing systems that allow water through the surface, land drains around the patio perimeter, and connections to existing soakaways or surface water drainage. The choice depends on soil permeability, patio size, and the volume of water to be managed.
Retaining Walls and Level Changes
Gardens with sloping ground often require retaining walls to create usable level areas. These walls hold back significant volumes of soil and water — they need proper engineering. We construct retaining wall foundations in concrete, designed to resist the lateral pressure of the retained soil.
Drainage behind retaining walls is critical. We install perforated drainage pipes in a gravel backfill behind the wall, with weep holes through the wall face to release water pressure. Without this drainage, hydrostatic pressure builds up and eventually pushes the wall over — one of the most common failures in garden construction.
DPC Level Compliance
Building Regulations require that external ground levels sit at least 150mm below the damp-proof course (DPC) of your property. When building patios adjacent to the house, this means the finished surface must be at this lower level. Raising ground levels above the DPC — even with paving — can bridge the damp course and cause moisture to penetrate your walls.
We check DPC levels during our initial survey and design the patio levels to maintain the required gap. Where existing ground levels are high, we may need to excavate deeper to achieve compliance. This is non-negotiable — getting it wrong causes expensive damp problems that are difficult to reverse.
