Abstract: A resilient, deformable, adhesive-free sealing strip for expansion joints in concrete comprises an elongated central core with a reinforcing web embedded therein. First, second and third pairs of fins extend from opposite sides of the central core, the first pair being shorter than the second and third pairs, the first pair disposed at the top of the strip and the second and third pairs being disposed at spaced intervals down the elongated core. Each pair of fins has a combined width greater than the width of the joint to be sealed. Upon insertion of the strip, the second and third pairs of fins are substantially deformed in the direction opposite insertion, exerting pressure against the concrete void walls, and through the central core, against one another, firmly locking the strip in place. The first pair of fins are only moderately so deformed, sealing the open top of the joint.

Abstract: An elastomeric strip has a support frame having selected regions of longitudinally displaceable frame portions such as wire loops reinforced by degraded and non-degraded materials that are non-degradable during the frame coating operation for inhibiting longitudinal displacement of the frame portions during the frame coating operation. The degraded material breaks down when the strip is flexed to allow increased flexibility of the strip, and the non-degraded material prevents undue elongation or stretching of the strip. A method of manufacturing the strip comprises reinforcing regions of the frame portions with degradable materials, arranging the reinforced support frame in position to be coated, coating the reinforced support frame with an elastomeric material, and then degrading selective regions of the degradable reinforcing materials.

Abstract: A joint former for hardenable material such as concrete comprises two essentially identical web members which are releasably attached to each other by a two-part friction coupling to form an assembly which is generally a T-shaped assembly. Each web is configured along at least one edge to form a first coupling part and along a central portion of at least one surface to form a second complementary coupling part so that any two of such webs can be attached to each other to provide a T-shaped assembly. In use the web forming the body of the T is inserted into the hardenable material, the bar web serving to align and position the inserted web. The bar web is then detached from the inserted web and releasably attached to another essentially identical web to form another T-shaped assembly suitable for use in the manner just described.

Abstract: A sealing element for attachment to a door, window or other structure comprises a resilient foam core enveloped by a wrap-around outer cover having a flexible portion and a relatively rigid portion for attaching the seal to another structure. The cover has opposite edges which are configured to lock together so as to contain the foam core. The seal may be produced by coextruding the portions of the cover, partially shaping the cover, laying in foamable core material, further shaping the cover, locking the edges of the cover together and causing the core material to foam within the interior of the thus-closed cover.
