Abstract of the Disclosure A bolster (10) is constructed of non-biodegradable material. The bolster (10) includes an elongated support member (12) and legs (14) for holding the support member in an upright position. An assembly (20, 22) is also provided to serially connect the bolsters together. More specifically, one end of the bolster includes a male connector (20) and the opposite end a female connector (22). The non-biodegradable material is impervious to water and both shatter-resistant and sag-resistant within a temperature range between 220° and -40°F. The material also has a flex modulus of between 200,000 and 1,500,000. Preferably, the material also bonds with concrete so as to form a substantially watertight seal.
