Flood Damage
Protection against Flood Damage
For homes that are at the risk of structural damage due to floods Permagreen can provide a number of solutions using the Technitherm system.
Technitherm® is shown to be the best performing type of cavity wall product according to a recent report on Flood Protection issued by DEFRA, DCLG and The Environment Agency. The report states that cavity wall insulation should be rigid closed cell materials, as these retain their physical integrity and have low moisture take up when exposed to flood waters.
Climate change couldl increase the number of properties at risk of flooding, in particular since many new houses were built in floodplains due to pressure for housing development during the 'Celtic Tiger'.
For floods deeper than 1m it is actually 'recommended' that youlet the water into your home, as build up of water pressure outside your property could cause the walls to cave in, leading to serious structural damage.
The Problem: Flood waters can penetrate cavity walls and cause major damage to the outer wall, the cavity wall ties, any fibrous insulation, the inner wall and decor.
The Flood Damage Solution:
Technitherm®, a water resistant, closed cell cavity insulant provides a solution:
- Protects the inner wall from flood damage
- Prevents corrosion of wall ties
- Prevents insulation damage
- Replaces wall ties where they are already in disrepair
The Outcome:
A closed cell cavity insulant such as Technitherm® has been recommended by UK Dept of Local Government, The Environment Agency and CIRIA as an effective flood protection measure for cavity walls.
