What do you want to work out
Rent vs. Buy
Should you rent or buy?
Move the sliders and we'll show you the break-even in months for your project.
Compares the cost of renting against the depreciation of buying (price − resale). Owning also adds maintenance, but leaves you an asset. Reference estimate.
Recommendation
BUYING wins
For 12 months, buying saves you $18,000 vs. renting.
- Rent 12 months
- $54,000
- Cost of buying (depreciation)
- $36,000
- Break-even
- 8 months
If you use it more than 8 months, buying pays off.
Cost per hour
What does each working hour cost?
Depreciation, fuel and maintenance: the real cost of operating your equipment.
A timely part and preventive maintenance lower the real cost per hour. Reference estimate.

Concrete
Concrete mix
How much cement, sand, gravel and water you need for your volume and target strength.
≈ 8 wheelbarrows
That's about ≈ 2 batches in the mixer.
Cement

bags (50 kg)
Sand
0.3 m³
≈ 4 wheelbarrows
Gravel
0.4 m³
≈ 6 wheelbarrows
Water

max — don't exceed
Approximate values (dry-volume method). For structural work, follow your engineer's mix design.
Before you take these numbers to site
These results are a sizing guide, not an engineering calculation. They depend on the material, moisture, equipment and site conditions. Validate them with the professional in charge of the works before buying, renting or executing.
Compaction
Which compactor suits you
Pick the machine by soil type, lift thickness and the space you have to work in.
1 · What kind of soil?
Density
Passes and density
How many passes you need to reach target density with the machine you have.
Recommended: 20–30 cm per lift.
85%
Target ≥ 95%
Compact in 20–30 cm lifts: any thicker and the bottom never reaches density no matter how many passes. Watch moisture (optimum is the Proctor value). And passes have diminishing returns: the first does a lot, the sixth almost nothing.

Pavement
Flexible pavement layers
Sub-base, base and surface thicknesses for the traffic the road will carry.
Asphalt surface · 5–10 cm
The wearing course you see and traffic rolls on. Compacted hot, no voids.
Compacted with
Smooth / pneumatic roller (tandem)
In our catalog: BOMAG BW 161 AD-50
See pavement equipmentEach layer is compacted before the next goes on. If a lower layer is loose, the whole pavement fails — that's why subgrade and base compaction matter most.

Lighting
How many light towers
How many towers you need to light the work area for the lux level the job requires.
≈ a work front about 22 m in radius. Choose by coverage, not just lamp count.
Standard tower (~7 m mast)
~7 m · 4 LED lamps
1 tower
covers ~2,200 m² each
Higher-output tower (~9 m mast)
~9 m · 4 high-output lamps
1 tower
covers ~3,300 m² each
Coverage figures are a reference estimate per tower class, not a datasheet value: they depend on mounting height, the reflector and the real shadows on site. Ask us to size it with your site drawing.
LED delivers more usable light at far less fuel than halogen — for repeated shifts, the diesel savings cover the difference. Taller mast = more area with fewer shadows. Check runtime on a full tank for the whole shift.

Spec sheet
What each figure means
Machinery spec sheets are full of acronyms. Here is what each one measures and why it matters when comparing.

How the site reads it
- Normalized weight
- 10.6 t
- Normalized power
- 128 HP
Only weight and power are normalized: they're the two measures comparable across brands. «Capacity» changes units by category (m³, kg, L, t), so it isn't used to filter.
