The Sipcrete system doesn have a cavity, does this cause damp penetration?
You can build with a cavity if you wish but when a Sipcrete wall is finished there are three seamless, continuous skins around the building. The System is ideal for Basements because of its waterproof properties. The Thermocore is totally water repellent and prevents water passing from one concrete skin to the other, if you wish you can add a waterproofing agent to the concrete, remember this type of concrete is used to build and hold water in swimming pools. This is why it is impossible to pass water across a Sipcrete Wall.
