Why Proper Groundworks Save You Money in the Long Run

Where a cheaper groundworks quote can become expensive

A low total is only useful if it includes the work your site actually needs. One contractor may include excavation, waste removal, drainage and reinstatement; another may price the digging alone. Compare the same drawings and scope before comparing the totals.

For an extension, a driveway or a concrete base, ask what has been allowed for beneath the finished surface. Problems are harder to investigate once a floor, wall or new paving is in place.

• Does the quote include removing existing surfaces and taking spoil away?
• Are the foundation or slab details based on the proposed use and the design?
• Have finished levels, thresholds and rainwater routes been considered together?
• Are inspection stages and any specialist work clearly assigned?
• What happens if the ground or buried drainage differs from the information available?

Five decisions worth making before the first dig

1. Establish what the ground can support

A nearby project is not a specification for yours. Made ground, trees, water and existing structures can change the foundation solution. Your designer should identify the investigation and structural design needed for the proposed work. The government’s Approved Document A covers structural requirements, including foundations and ground movement in England.

2. Agree the finished levels

A new patio or driveway must meet doors, paths, boundaries and neighbouring surfaces sensibly. Agree these relationships before choosing the surface finish. Changing them after installation can mean lifting good work to correct the layers below.

3. Decide where water will go

Adding a channel does not solve a drainage problem unless it has an appropriate outlet. The existing drains, the ground and any approvals need checking. Our Surrey drainage service covers external repairs, new drainage and rainwater work; the right approach depends on the site.

4. Plan access and waste removal

A narrow side passage, shared drive or limited loading space affects how the job can be done. Tell each contractor about access restrictions and ask whether plant, material deliveries, spoil removal and making good are included.

5. Set the inspection and handover points

Ask which stages need checking before concrete is poured or work is buried. Agree who books those checks and what records you will receive. Photos, agreed changes and relevant completion documents are more useful than a vague promise that everything will be sorted later.

Compare the scope, not just the headline price

Send the same information to each contractor: the site postcode, a description of the job, current drawings if available, access photographs and the intended use. Ask for exclusions and provisional allowances in writing.

Our groundworks quote comparison tool gives you a practical way to check omissions. If a price depends on an assumption about the ground, drainage or access, ask how a change would be assessed and approved before extra work starts.

There is no honest universal repair saving or cost per metre for every site. Dimensions, ground conditions, engineering, access and waste disposal all affect the price. A site-specific scope is a better starting point than an impressive-looking percentage.

Safe excavation is part of a properly planned job

Trenches can collapse and buried services can be damaged. HSE’s excavation guidance explains the need to plan support, identify services and inspect excavation safety. Do not enter a trench to inspect or measure it yourself.

Frequently asked questions

Does spending more always mean better groundworks?

No. What matters is whether the scope suits the design and site, the work is properly planned, and the quote makes responsibilities and exclusions clear. A higher price is not proof of better work.

Can I save by arranging my own waste removal?

It can be discussed, but agree the responsibilities first. Loading access, timing, the type of waste and lawful disposal still need to be coordinated with the contractor.

Can you price the work without drawings?

Photos and a site visit can help establish the next step. Structural foundations or other designed work may need further information before a reliable scope and firm price can be agreed.
