ᐅ Costs for Removing an Asphalt Overlay

Hello everyone,

I mentioned this briefly in another thread, but I think this part belongs here.

We are facing the decision of whether to buy and renovate a 1960s house or not. Unfortunately, the plot was previously covered by a Dutch tar company with nearly 200 sqm (2,150 sq ft) of tar.

Does anyone have experience with these tar layers? We estimate that the mixture exceeds limit values and is classified as "tar-containing," and that the layer is about 8-10 cm (3-4 inches) thick. As far as I can tell, breaking it up isn’t the biggest challenge – disposal is probably much more complex, right?

Does anyone have a rough price estimate for something like this? Assuming we have 200 sqm (2,150 sq ft) of 10 cm (4 inches) tar-containing asphalt on top of gravel only. We want to remove and dispose of the asphalt. If we consider only the asphalt, that’s roughly 20 m³ (700 cubic feet), so a large container.

What price range are we talking about for demolition and disposal? Could this be managed within 5,000 - 8,000 €?

Thanks very much for your help.

As is well known, 80% of people still say tar when they actually mean asphalt or bitumen.

It goes without saying that the whole thing is tar-free.

The original poster suspects that it is "tar-containing." If the material also comes from the time of the house construction (1960s), that could well be the case.

With your brief comments, you gave the impression that tar-containing materials would be reinstalled as well.

Here is a brief update: We now know that the tar surface is probably around 30 years old, meaning it dates back to the 1980s. If we're lucky, the asphalt might be tar-free. We'll see...

What is the name of the company that offered the cost point up to 5000 mg/kg at €33 per tonne (plus about €150 for 2 containers)? We have a quote of €70 per tonne :-(. Thanks in advance, Martin

So, for us it was the local landfill (Avea). However, the initial quote was later not honored. We sent in a soil sample for analysis (about 70€) and were lucky that there was no contamination.

Disposing of the material ourselves would have been difficult because we would have needed to rent an excavator, and the containers are handled quite differently. The following points were important for us to consider:

- We had about 50 m2 (540 sq ft) of asphalt. Using small 7 m3 (247 ft3) containers, we would have had container delivery and pickup costs of around 300 - 400€.
- The large roll-off containers (20 m3 / 706 ft3) would have just fit on our site (6 m length plus space for roll-off and maneuvering - plan at least 18 m / 59 ft of space!). However, they could only be filled up to 12 m3 (424 ft3) due to weight restrictions. They are also more expensive, so high fees again.
- Excavator rental is charged per day. If we had organized it ourselves, the container could only be emptied once a day, so the job would have taken about a week. That would have meant rental costs of roughly 1500€ including fuel.

In the end, we put the job out to tender on MyHammer and paid "only" just under 3000€ for a service provider who took the asphalt away directly instead of spending 3000€ on excavators and disposal ourselves.

Depending on the area, I would definitely recommend outsourcing this. In my experience, if you have more than 30-40 m2 (320-430 sq ft), you shouldn’t tackle it yourself unless you have a lot of time, physical strength, or money.

EDIT: We also tried using a jackhammer. It worked surprisingly well (asphalt is very soft) and we managed about 3-4 m2 (32-43 sq ft) per hour. However, it still had to be loaded manually into containers...
