WAC Testing & Waste Classification in Colchester
Soil sampling, UKAS WAC analysis and WM3 hazard assessment for sites across Colchester and Essex. Classification tells you where your arisings can legally go before you commit to a disposal route — which on most Colchester schemes is the difference between a straightforward muckaway and a stopped programme.
Colchester site conditions we plan around
A lot of local work is residential-led drainage and estate roads, so bedding stone and Type 1 move in phased call-offs rather than single big drops. Archaeology-sensitive plots around the historic core need careful sequencing, and clay arisings usually require classification before disposal.
Lead times & access
24–72 hours on stocked lines across CO postcodes. 8-wheel tippers for estate work, artic loads for larger platforms, grab and bulk bags for constrained town-centre plots.

How it works
01

WAC testing in Colchester — FAQs
Why does a Colchester site need WAC testing?
A licensed facility can only accept material it's permitted to take. Testing classifies the arisings from your Colchester dig so the right facility is booked first time, rather than a lorry being turned away and the programme slipping.
How long does WAC analysis take?
Standard turnaround is typically around five working days from sample receipt, with accelerated options from about 24 hours where the programme demands it.
Do you sample, or can I send my own samples?
Either. We can attend site and sample to BS EN 14899, or run the analysis on samples you've taken yourself if the sampling regime is sound.
Can testing and muckaway be booked together in Colchester?
Yes — that's the usual approach. We test first, confirm the route, then mobilise haulage to the licensed facility so there's no gap between classification and removal.
