This Video is for entertainment purposes only, to show that a GARDEN HOSE can produce the same results as any other preformed expansion joint product, but for less money.
We DO NOT Endorse or recommend this Method or any other prefabricated PVC/Rubber/Vinyl product for Expansion Joint Replacement without using a Polyurethane adhesive for bonding the Gasket to the substrate to allow proper expansion & contraction of the expansion joint and to provide a 100% water tight seal.

6.8-Installation of compression seals
Why Sealing is Needed
1.4 The introduction of joints creates openings which must
In buildings, to protect the occupants and the contents, it is
important to prevent intrusion of wind and rain. In tanks,
most canals, pipes and dams, joints must be sealed to prevent
the contents from being lost.
Moreover, in most structures exposed to the weather the
concrete itself must be protected against the possibility of
damage from freezing and thawing, wetting and drying,
leaching or erosion caused by any concentrated or excessive
influx of water at joints. Foreign solid matter, including ice,
must be prevented from collecting in open joints; otherwise,
the joints cannot close freely later. Should this happen, high
stresses may be generated and damage to the concrete may occur.
In industrial floors the concrete at the edges of joints often
needs the protection of a filler or sealant between armored
faces capable of preventing damage from impact of concentrated
loads such as steel-wheeled traffic.
In recent years, concern over the spread of flames, smoke
and toxic fumes has made the fire resistance of joint sealing
systems a consideration, especially in high-rise buildings.
The specific function of sealants is to prevent the intrusion
of liquids (sometimes under pressure), solids or gases, and to
protect the concrete against damage. In certain applications
secondary functions are to improve thermal and acoustical
installations, damp vibrations or prevent unwanted matter
from collecting in crevices. Sealants must often perform
their prime function, while subject to repeated contractions
and expansions as the joint opens and closes and while exposed
to heat, cold, moisture, sunlight, and sometimes, aggressive
chemicals. As discussed in Chapters 2, 3 and 6,
these conditions impose special requirements on the properties
of the materials and the method of installation.
