Asbestos Demolition Cape Town covers the asbestos side of taking a building down: the pre-demolition survey, the strip-out of asbestos-containing material before the machines arrive, and what happens when asbestos is found once demolition has already started.
The rule is simple. Asbestos comes out first, under controlled conditions, and only then does the building come down. Demolishing over the top of it contaminates the entire rubble stream.
Building size, age and demolition date. The earlier the survey, the cheaper the programme.

- Intrusive pre-demolition survey opening up voids, ducts, linings and floors
- Inventory and risk assessment covering everything the survey found
- Plan of work prepared and the asbestos work notified to the Department of Employment and Labour
- Asbestos-containing material stripped out by a registered contractor, working top down
- Waste wrapped, manifested and taken to a permitted hazardous waste facility
- Air clearance and sign-off that the structure is free of asbestos
- Conventional demolition proceeds, with rubble now going to ordinary disposal
Skipping the strip-out does not save money. Once asbestos is mixed through demolition rubble, the whole pile becomes hazardous waste and the disposal bill multiplies several times over.
What Gets Stripped Before The Machines
- Roof sheeting, ridges, gutters, downpipes and fascia
- Ceilings, soffits, bulkheads and cupboard linings
- Wall cladding, partitions and insulating board
- Pipe lagging, boiler and geyser insulation, flues
- Asbestos cement water and sewer pipes in the ground
- Floor tiles and the bitumen adhesive under them
- Electrical backing boards, fire doors and fire-stopping
- Fixed plant linings in workshops and plant rooms

| Clean rubble disposal | R180 – R500 per tonne | What it costs if it is done right |
Indicative ranges, not quotations. The gap between the last two rows is the entire argument for doing the survey and strip-out first.
Survey, strip-out and clearance priced as one package, ahead of the demolition contractor.

It happens, usually because a management survey was commissioned where an intrusive one was needed. Stop work, keep people off the area, do not move the rubble and do not damp it down with a hose. Get a contractor and an inspection authority on site to assess how far material has spread. Rubble that has already been mixed has to be assessed load by load, and in the worst case the whole pile is treated as hazardous waste. The cost of stopping for a week is almost always less than the cost of disposing of a contaminated pile.
Frequently Asked Questions
Does asbestos have to be removed before demolition?
Yes. Asbestos-containing material is stripped out under controlled conditions first, by a registered contractor, before conventional demolition starts.
What survey do I need before demolishing?
An intrusive pre-demolition survey, not a management survey. It opens up ceilings, voids, ducts and floors, which is where the material a management survey misses tends to be.
What if asbestos is found after demolition starts?
Stop, isolate the area, leave the rubble alone and get it assessed. Moving or wetting it first makes the assessment harder and can spread material further.
Can the demolition contractor do the asbestos too?
Only if they are separately registered for asbestos work. Many demolition firms are; many are not and subcontract it. Ask for the registration certificate either way.
How much does the strip-out add to a demolition?
Typically R180 to R420 per square metre of asbestos material, plus survey, notification and clearance. Against contaminated rubble disposal at R1,800 to R4,500 per tonne, it is the cheaper path by a wide margin.
