Your questions, our answers
At JJN Groundworks, we understand that groundworks projects can raise a lot of questions. Whether you're planning a new patio, an extension, or considering a drainage solution in Midhurst, we believe in clear, transparent communication. We've compiled the most common questions our clients ask to help you understand our process and commitment to excellence.
Frequently asked questions
We pride ourselves on our professionalism and the quality of our work, from the very first consultation to the final sweep of your driveway. Our goal is to provide you with all the information you need to feel confident and informed throughout your project.
Before you work with us: How long will my garden be a building site?
We understand this is a major concern. With our Strict Continuity Policy, once we break ground on your project, we are on-site every working day until the job is signed off. We provide clear start and end dates, eliminating "open-ended project" anxiety and ensuring your garden returns to normal as quickly as possible.
Before you work with us: How do you ensure the patio won't sink or the extension won't shift?
Our Ground-Up Engineering approach is key. We focus on what's underneath. This involves careful consideration of the sub-base depth, meticulous compaction techniques, and expert drainage management. We don't just "slap slabs on sand" – we build foundations that last.
Before you work with us: How do you handle the waste and the mess?
Waste management is a core part of our service. We utilise grab lorries or skips to keep the site clear and tidy. Our "Clean Site" policy ensures your driveway is swept and the area is secured at the end of every single day, minimising disruption and mess for you.
Once the project starts: It looks like a lot of dirt... is all of that coming out?
When we excavate for a patio or foundation, the "spoil" (dug-up dirt) can look overwhelming. Rest assured, we have a clear muck-away process. We'll let you know exactly when the grab lorry or skip is arriving to remove the waste, ensuring the "messy phase" is controlled and temporary.
Once the project starts: Why is there so much stone going into the hole?
This is part of our "Built to Last" philosophy. The stone (Type 1 MOT or hardcore) forms the essential "skeleton" of your patio or foundation. We compact it in precise layers (typically 50mm–75mm) to ensure unparalleled stability and longevity, preventing any future movement.
Once the project starts: What happens if it rains tomorrow?
We're well-versed in Southern Englands weather! We implement effective weather management, protecting the site with tarps and boards. Our "One Job" promise means we won't leave for another site if rain pauses work; we'll stay until the weather window opens to ensure the job is done right, never rushed.
Our "Daily Briefing" Strategy
To keep you fully informed, Josh, our director, provides a quick 2-minute chat at the end of every day. We'll cover what we've achieved, what's planned for tomorrow, and anything you need to know (e.g., "Keep the side gate clear for the delivery.").
Groundworks confusing aspects: Why is the excavation so deep for a patio or foundation?
Many people are surprised by the depth. The excavation depth is crucial for creating the "invisible" sub-base – the actual foundation that supports the weight. Without a properly compacted Type 1 MOT base, your patio slabs could eventually sink, tilt, or crack, especially with frost.
Groundworks confusing aspects: Wait, is my patio sloping?
To the naked eye, a patio should look flat. However, for proper drainage, every patio needs a "fall" – a slight, imperceptible gradient (usually 1:60 or 1:80). This directs rainwater away from your house and towards a drain or flower bed, preventing puddling or a "swimming pool" effect.
Groundworks confusing aspects: Why are we digging a metre deep for a small wall?
Footing depths depend significantly on the soil type. In areas with high clay content, like parts of Midhurst, the ground "heaves" (expands and contracts) with weather changes. We must dig deep enough to reach stable ground, ensuring your structure remains solid and doesn't move over time.
Groundworks confusing aspects: Can't I just drain the driveway into the street gutter?
Due to strict UK regulations (Sustainable Urban Drainage Systems – SUDS), direct drainage into street gutters is usually not permitted. Modern driveways must either be permeable or drain into a "soakaway" on your own land to manage rainwater responsibly and prevent flooding the local sewer system.
Our 'One Job Guarantee': Does 'One Job' mean you won't leave for an emergency?
Our commitment is ironclad. While we'd handle urgent safety issues immediately if they arose, your site is our sole focus. Our team and machinery are dedicated to your project. We don't "site-hop" to chase other work; when we're there, we're there until completion.
Our 'One Job Guarantee': If I’m your only job, does that make you more expensive?
Actually, it's the opposite. By staying on one site, we significantly reduce fuel costs, machinery transport fees, and wasted travel time between jobs. This efficiency allows us to provide a highly competitive quote while ensuring a faster, more focused finish for your project.
Our 'One Job Guarantee': How do you handle 'hidden' groundwork issues without breaking the schedule?
Our groundworks-led expertise means we're adept at spotting potential issues early, such as problematic pipes or unstable soil. As the hands-on director on-site, Josh can pivot and solve problems immediately, avoiding delays that might occur when waiting for external sub-contractors.
Our 'One Job Guarantee': Why do you emphasize the 'Ground-Up' part so much?
We often explain that the "pretty" part of a patio or extension is only about 10% of the work. The "Ground-Up" focus ensures the 90% underneath is flawless. For example, an expensive porcelain tile is brittle; if the ground moves due to a poor sub-base, that investment will crack. We're selling you insurance for your entire project.
