WAC Testing & Waste Classification in Slough
Soil sampling, UKAS WAC analysis and WM3 hazard assessment for sites across Slough and Berkshire. Classification tells you where your arisings can legally go before you commit to a disposal route — which on most Slough schemes is the difference between a straightforward muckaway and a stopped programme.
Slough site conditions we plan around
Industrial and data-centre plots take volume Type 1 and capping to a strict daily tonnage, often with vehicle-booking systems and timed gate slots. Residential regeneration in the town centre is the opposite — tight plots, grab access and phased small loads. Made ground on former industrial land makes WAC classification routine.
Lead times & access
Stocked lines within 24–72 hours across SL postcodes. Artic and 8-wheel loads for trading-estate and Heathrow-corridor work with timed gate bookings; grab and bulk bags for town-centre plots.

Options for Slough sites
Sample screen
Basic classification screen to confirm whether material is inert, non-hazardous or hazardous.
Full WAC suite
Complete leachate analysis for landfill acceptance where the facility requires it.
On-site sampling visit
Our sampler attends, takes representative samples across the stockpile or dig and logs the locations.
Fast-track turnaround
Accelerated lab options from around 24 hours where the programme can't wait.
How it works
Sampling
Representative samples taken to BS EN 14899 across the material to be moved.
Laboratory analysis
UKAS lab runs the agreed suite, from screen through to full WAC leachate testing.
Classification and route
WM3 assessment issued, then we confirm the licensed facility that can accept the material.
Compliance and paperwork
Sampling follows BS EN 14899, leachate testing follows BS EN 12457-3 and analysis is carried out by UKAS-accredited laboratories, with WM3 assessment reports for your site file.
Our credentialsWhat shapes WAC testing in Slough
Classification matters in Slough because of made ground that makes WAC classification routine before anything moves. With made ground on former industrial plots, arisings from neighbouring plots can behave very differently, so sampling across the dig rather than one spot sample is what keeps the result usable. On data-centre and industrial plots plus town-centre regeneration we test first, confirm the facility, then mobilise haulage — the same sequence across Windsor, Maidenhead and Uxbridge.

WAC testing in Slough — FAQs
Why does a Slough site need WAC testing?
A licensed facility can only accept material it's permitted to take. Testing classifies the arisings from your Slough 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 Slough?
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.
Is WAC testing available before muckaway?
Yes — BS EN 14899 sampling, UKAS WAC analysis and WM3 assessment, which is worth doing early on former industrial land in Slough.
