Preparation
As the membrane systems are mechanically fixed there is no reliance on the ability of the product to bond to the substrate. The DELTA system can be applied to a variety of different substrates for example over existing renders or broken down bitumen coatings, etc.

This can be easily achieved without detriment to the integrity of the system.

Damp Pressure Equalisation
The studded structure of the membrane allows the dampness behind the membrane to move in all directions unhindered, therefore the whole of the wall or floor surface takes the damp loading. Break down created by weak points are eliminated.

The product does not divert the problem to other areas.

Flexibility
In structures where movement or vibration are a problem, examples being under street vaults, railway arches, and buildings constructed with movement joints, the DELTA system can cope.

The DELTA membrane has an elongation break of greater than 50%.

Speed
As there is little or no preparation required the system is by comparison quick to install. When dry finishes are used the system is a "fast track" solution. Decoration does not need to be delayed as there is no drying process. DELTA membrane systems are the UK arm of the world's largest producer of studded membrane systems. The market leading DELTA brand has a track record exceeding three decades.

The DELTA systems have been used successfully in many situations in the UK From small domestic basements up to major waterproofing projects such as, London Underground Stations. There is rarely a dampness or water ingress problem that falls outside the scope of the capabilities of the DELTA system.
