The Last of the Demolition


Gone West

Recommended Posts

After we dismantled the bungalow we were left with 45 to 50 tonnes of mixed concrete, bricks and blocks along with around 10 tonnes of footings that needed digging out and removing from site. We finally found a groundworks company that would bring a concrete crusher to site and crush the mixed rubble from 50mm down to dust and dig out the footings and remove. We asked three companies for quotes which came in at £4320, £2154 and £1390. The only one that would crush on site to the size we wanted, rather than remove everything and bring in crushed concrete, was the cheapest so we went with them. We have seen what some suppliers bring in as crushed concrete and it’s crap. It took a day to crush around 35 tonnes of the best of the rubble and another to break out the footings and remove along with the remainder of the rubble. They were a company we would definitely recommend which was nice to be able to say.

I see the crusher seems to be available to hire - would that have been a cheaper option?  I guess you would have had to load it by hand that way, but it would depend on what sort of saving could be made as to whether it was worth it.

There was a substantial saving by having it crushed on site rather than having it all removed and new recycled type1 brought in. It would have taken several days to load it by hand and a broken back!

@PeterStarck, am I correct in thinking you hired a concrete crusher yourself after the above where you had someone in?

 

Thinking of one of these for a weekend:

We only had the concrete crushed once which was with a 5000 series machine. They set the jaws at more than 50mm so we had to manually grade the crushed material through a 50mm mesh. If it doesn't pack up on you and there are enough of you to keep it fed then you can get a reasonable amount done. It depends how big the lumps are to start with and how small you want the final material. It is quicker to pass it through the crusher twice with large lumps than to try to get the size you want in one pass unless the lumps are small to start with.
