Delta Membranes have supplied several their internal and external systems to prevent flood damage for Rose Hall Cottage, a private residence in Banbury.

The kitchen of the property was prone to water ingress along the base of the external wall during heavy rainfall due to water bearing against the base of the external stone wall.

The road profile forms a natural low point outside the kitchen where surface water was prone to pond, flooding was typically due to heavy rain and perches for a short duration.

Delta provided their Type C Drained Protection which is common in structural waterproofing schemes where external ground levels are high and there is a likelihood of water in the ground.

The main components of the system are the cavity drainage membranes.

These are sheets manufactured from virgin HDPE which are extruded into studs which come in various depths, an 8mm
membrane used in this pr oject.

With the floor finishes and kitchen units removed a min. 50mm deep 100mm widechannel chase was cut at the wall & floor joint draining to a Delta Single V3 sump and pump unit. The chase was Bunded.

The inner face of the existing wall was then lined using Delta MS500 cavity drainage membrane fixed using sealed Delta Plugs. The whole of the existing kitchen slab was lined over using 3mm profile Delta FM membrane.

Externally, Delta Koster Façade cream was applied along the base of the wall to increase the water repellent properties of the wall.
