Log Storage

Logs need to be stored under conditions that will prevent occurrence of defects associated with shrinkage or attacks by fungi and insects. Defects associated with shrinkage are minimum during periods of precipitation and high relative humidity. Fungi and insects are mostly inactive at low temperature.

Logs should be sawn into lumber as soon as they are taken from the woods. If prompt sawing is not practical, two general types of log storage: ponding and cold decking provide reasonable protection.

Pond Storage

A log submerged in water is protected completely from drying defects and from insect and fungi attacks. However some parts of most logs stored in ponds are above water and may develop drying defects such as end checking, and they are exposed to attacks by insects and fungi if stored too long during warm weather.

Cold Deck Storage

Logs in cold decks may be effected by drying shrinkage and insect / fungi attacks during warm weather. Occasionally logs in cold deck storage are sprayed with water to keep them wet thereby lessening the development of defects due to drying shrinkage. End checks and end splits in logs can also be reduced by applying a good coating to the ends of the logs.

Lumber Storage

Outdoor storage: The storage area must be open and well drained, and kept free of weeds and debris that restrict air movement along the surface of the ground, harbor insects and fungi, and create a fire hazard when dry. The ground should be surfaced with gravel, crushed rocks, blacktop or concrete. Green and partially dried lumber could be stored outdoor with proper stacking method.

Open shed storage: The shed should be located on an open, well drained area. It should be large enough to permit rapid handling of the lumber, and have a floor or gravel, crushed rocks, blacktop or concrete firm enough to support the weight of piles of lumber and handling equipment. It is good for storing green lumber and partially dried lumber. Kiln dried lumber can also be stored for a limited time in a certain air condition.

Closed shed storage: Closed sheds protect lumber from elements. The shed should be provided with reasonably tight fitted doors. Closed sheds can be fitted with ventilators and fans depending on the requirement of drying the green and partially dried lumber. Closed shed may even have an air heater if necessary. Stocks stored in closed, heated shed include hardwood dimension, furniture stock, etc. that will be used inside heated buildings.

Finally it is wise to keep the cut wood (before, during and after the fabrication ) in the surroundings as similar as possible to where it will be finally placed.
