External wall deformation joint node does not confirm the practice
(1) The external wall settlement joint cover seam is fixed on both sides of the iron, and the long round hole is made into arc less than the slit width a 40 40. The arch curvature is insufficient, the soft PVC foam is plugged, and the asphalt is used to adhere to the clear wall seam.

(2) Deformation joints of external walls, especially deformation joints mainly based on uneven settlement. When two small corrugated aluminum alloy plates are used to overlap the cover seams, the middle of the two plates overlaps with rivets instead of long rounds. The sliding hole cannot be freely stretched, which is easy to cause the surface layer of the wall on both sides of the vertical joint to be cracked due to improper handling, resulting in a quality hazard.
(3) The outer wall expansion joint or anti-seismic joint adopts circular arc-shaped stainless steel plate, but the arching curvature is insufficient, which can not meet the expansion and contraction requirements of the wall due to temperature change or earthquake action, and form a quality hazard.
(4) The decorative surface layer of the deformed joint of the mixed water wall covers the outer surface of the covered iron, which causes the ash adhesion of this part to be not strong and forms a quality hazard.
(5) The cover seam is not firmly fixed and is directly fixed to the brickwork with steel nails.
Fiberglass Geogrid
Fiberglass Pavement Mesh is a product that uses a continuous coating of fiberglass as an ideal highway pavement reinforcement.
Pavement Geogrid is characterized by high tensile strength in both axial and lateral direction, low stretch rate, high temperature-resistance, alkali-resistance, easy construction, and low price. Warp knitted Fiberglass Geogrid can be used on pitch pavement, bituminous concrete pavement, and cement pavement to prevent cracks and prolong pavement service life. It also can be used as basal reinforcement material on hillsides, reservoirs, harbours, ports, water channels and sea walls.
Specification:
Mesh Size:12.7mmx12.7mm, 25.4mmx25.4mm, 30mmx30mm, 40mmx40mm, 50mmx50mm etc.
