Final photos of a repair on a damaged system... I lost some photos 🤦‍♂️

As you can see, this property which is on a flood plain and is looked after by ourselves, with yearly maintenance, most properties like this, can have a protection against flood water!

This system was installed many, many years ago by ourselves and servicing the system regularly has provided protection against the flood water from the river that runs in front.

Even when its been damaged, repair work can be carried out, one of the many benefits of incorporating a Type C tanking system into any design for a flood prevention or basement tanking systems.

If you have a damp or wet space in your property and need it to be dry and usable, give us a call, we can help.

Dont live in fear of the next high water.

This property showed no visible signs of dry rot initially to this area.
Fast forward four months, the floors have failed — exposing the hidden sub‑floor voids and a real problem beneath.
What lies below can be a frightening discovery.

Dry rot cannot be surface treated.
The only effective solution is:
• Removal of all affected timbers plus a minimum of 1 metre in every direction
• Full irrigation of masonry (surface spray is not a treatment)
• Treatment of all replacement timbers with a deep‑penetrating preservative paste
• Ventilation to all voids

If any untreated timber is left in place, re‑used, or if walls aren’t fully treated, dry rot will continue to spread throughout the property.

This is why using experienced specialists matters.

At Tywi Damp Proofing, we’ve been treating dry rot for over 40 years under the same company name.
Don’t take the risk — call the specialist.

Enjoy your Easter treats this weekend 🐣
If you have concerns about your property, give us a call when we’re back on Tuesday.
