Every stand raises the same question before the first sod is turned: hand or TLB? The pool excavation hand TLB decision isn’t a matter of preference. It’s dictated by what the site actually allows — how wide the gate is, how close the neighbouring wall sits, whether a mature tree’s roots run under the proposed shell. Get this call wrong and you either waste days digging by hand when a machine could have done it in hours, or you drive a TLB through a spot that damages paving, drainage or a root system you needed to protect.
We assess this on every site before quoting, not after. It affects the timeline, the crew size, and how much disruption your garden takes during the build.
What a TLB actually brings to a dig
A TLB — a tractor-loader-backhoe — is the standard machine for pool excavation across Gauteng. It digs, lifts, and loads spoil in one continuous motion, which is why a straightforward, open-access site can go from marked-out ground to a finished hole in a single day. Where a stand has a driveway wide enough and a gate the machine can pass through without scraping a wall or a gatepost, TLB excavation is almost always the faster and more cost-effective route.
The trade-off is footprint. A TLB needs room to manoeuvre, not just room to enter. It needs a turning circle, a place to stage the spoil before it’s loaded onto a truck, and enough clearance that the operator isn’t guessing centimetres away from a boundary wall or an existing pergola. On a cleared, standard-shaped stand — the kind you find on newer estates with wide driveways — none of this is a problem. On an older, tightly landscaped property, it often is.
When hand-digging is the only option
Hand excavation comes in wherever a machine simply can’t get to the hole, or can’t work safely once it’s there. Narrow side access is the most common reason — a gate too tight for a TLB’s width, or a run between the house and the boundary wall that a machine would clip on both sides. Mature trees close to the dig line are another. Root systems that took decades to establish don’t survive a machine bucket working within a metre of them, so the crew digs by hand to protect what’s already growing.
Sloped stands, retaining walls close to the pool position, and existing paving the homeowner wants to keep all push the job toward hand digging as well. It’s slower and it’s more labour-intensive — there’s no way around that. But it’s also the only way to excavate some sites without damaging the very features that made the property worth buying in the first place.
| Method | Best suited to | Typical constraint | Effect on the build |
|---|---|---|---|
| TLB | Open stands, wide driveways, cleared new-build sites | Needs turning space and a clear entry point | Excavation often finishes in a day |
| Hand digging | Narrow access, established gardens, sites with mature trees or retaining walls | Labour-intensive, slower by nature | Takes longer but protects surrounding features |
| Combination | Sites with a clear entry point but a tight final approach to the pool position | Machine opens the hole, crew finishes by hand | Balances speed with precision near boundaries |
Many sites don’t fall cleanly into one category. A TLB can open the bulk of the excavation where access allows, and the crew finishes the last stretch by hand where the machine can’t safely reach — close to a boundary wall, for example, or around a tree’s root zone. This combination approach is common and it’s usually the most efficient answer on a site with mixed constraints.
Marking out and squaring the site comes first
Before any digging starts, hand or machine, we mark out and square the site against the design. This step checks the pool’s position against boundary walls, existing trees, drainage lines and any features the homeowner wants kept. It also confirms, on paper and on the ground, whether the access route you assumed would work actually does.
This is where an access problem gets caught early, rather than halfway through a dig. Adjusting a pool’s exact position by half a metre at the marking-out stage costs nothing. Discovering the same problem once a TLB is already stuck against a gatepost costs time, and sometimes costs a repaired wall too.
Getting the spoil off site
Digging the hole is only half the job — the excavated soil has to leave the property, and how it leaves depends on the same access constraints. A TLB loads spoil directly onto a truck parked close to the dig, which is fast and requires very little manual handling. Where a machine can’t get close enough, the crew wheelbarrows spoil out through the same narrow gate or path that ruled out machine access in the first place.
This is one of the reasons hand-dug sites take longer than the hole size alone would suggest. Moving several cubic metres of soil by wheelbarrow, through a gate, and onto a waiting bakkie or trailer is simply slower than a bucket loading straight into a tipper truck. Industry estimates for excavation work generally put labour as the largest single cost driver, whether the method is hand or machine — it’s the time on site that adds up, not the equipment.
How access affects your timeline
The pool excavation hand TLB choice has a direct effect on how the rest of the build schedule falls into place. A machine-accessible site clears the excavation stage quickly, which means steel and shuttering can start almost immediately after. A hand-dug site needs more days built into the schedule at this stage, purely because the digging itself takes longer.
None of this changes the quality of the finished shell. Both methods get you to the same point — a squared, correctly sized excavation ready for steel and concrete. What changes is how many days it takes to get there, and that’s worth knowing before you commit to a start date, particularly if you’re working around a school holiday or an event you want the pool ready for.
Preparing your site before excavation day
A few things on the homeowner’s side make the excavation stage run smoother, whichever method applies to your stand:
- Clear vehicles, furniture, or garden features from the access route the crew and any machinery will use.
- Flag any underground services you know about — irrigation lines, old drainage, buried cabling — before marking out begins.
- Confirm gate widths and driveway clearance if you’re not sure whether a TLB will fit.
- Let the crew know about any trees, root systems or retaining walls you want protected, even if they seem outside the dig area.
- Check with your body corporate or estate management if delivery vehicles and machinery need prior approval to enter.
Sorting these out before the crew arrives avoids the kind of on-site delay that costs more than the digging itself — a truck that can’t park, a gate that turns out to be narrower than measured, a tree root nobody flagged.
Frequently asked questions
Does hand-digging cost more than TLB excavation?
It takes longer, which is the main practical difference. Trademen Pools quotes new builds as one overall price rather than itemising excavation separately, so the method used is already factored into the figure you’re given — you’re not billed differently depending on which approach the crew uses.
Can any property have a TLB brought in?
Only if there’s a clear route in and enough room for the machine to work safely once it’s there. Narrow side gates, tight driveways, and boundary walls close to the dig line are the most common reasons a site can’t take a machine at all, or can only take one partway.
Will hand-digging delay my build?
It adds days to the excavation stage specifically, because moving soil by hand and wheelbarrow is slower than a machine loading directly onto a truck. It doesn’t affect the quality of the finished shell, and the rest of the build — steel, concrete, finish, commissioning — follows the same sequence regardless of how the hole got dug.
Who decides which method to use?
We do, based on a site assessment before the quote is finalised. Access, space, existing trees, walls and paving all factor into that call, and it’s confirmed again when the site is marked out and squared, before any digging actually starts.
