Preparations

It is important that the ground beneath a deck is completely cleared of all building rubbish, garden debris and obstructions to water or air movement. Water must not be able to pool under the deck and the ground must be sloped away from the foundations of the house. Agricultural drainage pipes may be required in some instances so water can properly ow away from beneath the deck.

Even though eXtreme Joist are H4 treated, it should not be subject to permanent contact with fresh water, if the timber will be in permanent contact you will require H5 or higher.

Plastic sheeting acting as a waterproof membrane should be placed on the cleared ground. If timber bearers are to be placed directly on the ground, the plastic sheet should be covered with compacted gravel or sand to provide a solid base.
