An expansion joint for providing a rodent-proof barrier. The expansion joint comprises an elongate core formed of a resiliently deformable material, and a flexible sheath of a barrier material covering at least a part of the elongate portion of the elongate core. The elongate portion of the elongate core is compressible in a direction perpendicular to a line between the first and second ends of the elongate core, the elongate core being arranged to be compressed and inserted into a gap between first and second building structures, and to expand after insertion into the gap so that the expansion joint is held in place within the gap by friction between the surface of the flexible sheath and the surfaces of the first and second building structures.

The present disclosure relates to a pole shield for extending around a pole structure. The pole shield comprises one or more than one sheet of composite material forming a hollow structure having an open first end and an opposed open second end. The sheet or sheets of composite material comprise from about 50% to about 80% by weight of a reinforcement impregnated with about 20% to about 50% of a polyurethane resin composition comprising a combination of a polyol component and a polyisocyanate component. Two or more pole shields may be stacked one on top of the other to form a pole shield structure which extends the height of protection of the pole structure. The pole shield can be used for protecting a pole structure from damage, such as from fire, rain, wind, sand, ice, pests, moisture or electrical. The pole shield may also be used to provide structural support to a pole structure.

Weep hole insert (10, 10) comprising a tubular body (12) defining an air flow conduit (14) extending therethrough, along axis (L), from a first open end (12a) to a second open end (12b) of the body. Grate (16) comprises a perforated body (16a) configured to permit air flow but to inhibit passage of embers and sparks. In an operative configuration, perforated body (16a) extends across the conduit (14). Elastically compressible member (16c) is engageable between perforated body (16a) and an interior surface of body (12) to releasably secure the perforated body in the operative configuration. When engaged between body (16a) and the interior surface of body (12), member (16c) is elastically compressed from an expanded configuration to a compressed configuration by a distance of at least a wall thickness (T) of body (12) at its point of engagement by member (16c).

A barrier system includes a substantially vertical structure with a coating layer disposed on and circumscribing a majority of the substantially vertical structure. The coating layer has a height of at least 0.25 inches, has a dried film thickness of at least 5 mils, and has an average surface roughness (R.sub.a) of less than 10 microns.

The invention relates to a removable deflector for protecting the feet of a structure, which corrode following infiltration of water under the bottom plates and which weakens these areas. The invention concerns a removable device enabling the positioning of protection for the feet of storage tanks without a shut-down of production. The device according to the invention is a deflector element and a deflector assembly consisting of a plurality of deflector elements, capable of being positioned one after the other in order to surround the feet of the wall of the structure. Each deflector element comprises at least one downward-sloping protective plate (1), at least one flexible sealing gasket attached along the upper edge of this plate (1), and: at least one retaining arm (5) for same, wherein one of its ends is fixed to the so-called upper edge of said plate (1) and the other so-called distal end is capable of being rigidly and reversibly attached to an element of said structure and to be detached therefrom, this arm allowing the adjustment of the pressing of the sealing gasket against the wall (14) of the tank, and at least one support (6) arranged towards its lower edge and separable into at least two parts suitable for making the deflector removable, of which the upper one is attached underneath the plate (1) and the other, lower one, is attached to the support slab (23) of the structure wall (14).
