Drain Relining Question with smell

[loziv]

Hi

We had our drains relined yesterday which runs under our house (kitchen). There is still a very strong chemical smell in the house today (24 hours after) and its so strong that you can not really stay in the kitchen or adjacent rooms for very long as its so strong a chemical smell. You can even smell it if you open the kitchen cupboards.

We have had the windows open but makes little difference as the chemical smell is coming up from the ground.

I just wanted to ask if this is normal? I thought the smell would go quite quickly once the resin used for relining the drains had set, which should be about an hour?

Many Thanks

Have you got earthen floors?

 

[loziv]

Don't think so, they are concrete

Any connection into the drain under the floor within the room?

 

[loziv]

no, it runs under the floor to another inspection chamber outside the property

loziv, good evening.

A couple of things?

if the drains had to be relined, then there must have been some fairly large defects in the drain line? was the drain subjected to a CCTV Survey? if so are there any junctions coming into the drain line somewhere in the middle of the floor plan??

During the lining process any excess resin can, I stress, CAN be squeezed out of the gaps in the drain line and into the surrounding earth or Concrete from there is will very slowly evaporate into the house.

A question as regards the construction of the sub floor area? when you say it is "Concrete" sorry to press, but? is it a concrete slab, that is a solid floor or? do you have timber suspended flooring with Joists?

If you have a suspended timber floor, then any Resin odour caused by any resin being squeezed out of the drain line will slowly escape into the underfloor area, then into the rooms above, from what you say it appears that the worst area od drain damage was below the kitchen.

Hi Ken

Yes we had CCTV and there were some cracks and joint displacements. There are no junctions in the middle of the floor plan its a straight run to the chamber outside. I have read that it can take about 48 hours for the chemical smell to go?

The floor in the kitchen where this line runs under is concrete (or at least its a solid floor) the rest of the house is suspended flooring with joists, but no drain runs are under the rooms with suspended flooring.

An update - the smell of the chemicals is still as strong as it was. So much so that you can smell it on the plates, even in the oven and in the kitchen cupboards.

When they installed the drain liner they had to use cold water rather than use an air compressor or hot water, is this why the smell is so strong, as it has not fully set yet?

Is the smell dangerous or is it just unpleasant, sorry for the questions but I have 2 young children at the property and just wanted to check if its safe.

Are you sure the smell is not 'chimneying' up from an untrapped pipe?

loziv, Good evening.

One Question? was this an insurance claim?

If so the Insurer will have to sort this smell out, they instructed the repair, if they were involved?

Hi ken

Yes, don't think it's channeling it's a straight run under the floor

The chemical smell is everywhere , to the point where you can taste it in food (cereals) etc that's in the cupboard and when using the fan oven

How can you rectify the smell though, dig it back out?

loziv, Hi again.

instant thoughts are ventilation, but as the weather is shall we say cooling? not an easy option?

As my last post were insurers involved? Important because if they were then you can have them fund the odour removal, and not just bey spraying a nice smelling odour reduction material
