What Can I Do For You?
expansion joints are placed in concrete to prevent expansive cracks formed due to temperature change. concrete undergoes expansion due to high temperature when in a confined boundary which leads to cracks. expansion joints are provided in slabs, pavements, buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.
squeeze the sikaflex sealant into the concrete expansion joint and allow it to flow & self-level itself. add more sikaflex where it’s needed. voila!!! your concrete expansion joint is now watertight and way more unlikely to crack. in case you’re more into watching than reading here’s a video showing you what to expect when using sikaflex
concrete joints are used to compensate when concrete expands or shrinks with changes in temperature. concrete joints are normally used to prevent cracks when the concrete shrinks by creating forming, tooling, sawing, and placing joint formers. the pre-planned cracks will provide a better finish concrete product and will be formed in specific locations where those cracks could be monitored.
after concrete is poured and moulded into shape it will harden and set which naturally causes a reduction in volume. steel reinforcement (within the concrete itself), granular fill, and adjoining structures can restrain the shrinkage and can lead to tensile stress within the concrete area. tensile stress can cause the weakest area of the concrete material to crack and that is where expansion
attach tear-side-up to the adjacent material before pouring next concrete section. attachment can be made with construction adhesive, nails or staples. be sure that the top of the expansion joint foam is set at the top of the intended concrete pour. expansion joint material includes a built-in “tear-off” strip.
introduction: any concrete structure that is going to require numerous movement joints, is best designed by a civil or structural engineer. all concrete, once placed, will contract slightly during the curing process; this is the primary cause of small surface cracks that appear during the curing process.
expansion joint cap to install, slide snap-cap over the top of the expansion joint. place the concrete and screed to finish grade as usual. when concrete is cured, insert a screwdriver through the top of snap-cap, pull free and discard. the joint is ready to seal. plastic joint materials size information
concrete isolation joints, or expansion joints, separate or isolate the concrete from other parts of the building structure like walls, footings, columns and piers. a concrete expansion joint is also used to separate a concrete driveway or patio from a garage slab, sidewalk, stairway, light-pole or any other point or restraint. the materials
gutter sections. preformed joint filler material must extend com-pletely through the entire thick-ened-edge slab. plugs or slivers isolation and expansion joints in concrete pavements by james w. mack improper use of expansion joints can lead to pavement failure and high construction and maintenance costs when to use expansion joints
the material you use between these joints needs to be strong, flexible and resistant to water ingress. growtivation’s siteworx range offers two types of expansion joint filler solutions for this: the fibreboard expansion joint filler is ideal for filling concrete expansion joints, while our foam expansion joint filler is perfect for using
this unique elastomer possess a variety of important qualities that make it the expansion joint industry standard material. chlorobutyl has exceptionally low permeability to gases, excellent vibration dampening properties, and good heat, chemical, ozone, and oxidation resistance.

it’s a one component sealant that forms a flexible joint with excellent adhesion. translation: it’s simple to use and helps you get the job done right. use it to seal joints in concrete slabs, replace expansion joint material or repair cracks in concrete slabs.

a pliable material is used (asphalt coated, cork, plastic) to construct these types of joints. the material should extend the depth of the slab and extend the full width of the slab. ideally, for expansion joints on the exterior of a structure, sealing these joint is preferable.
construction joint is essential if the size or length of concrete members exceeds some specified limit.. generally for short-length concrete member construction joints are not required, because for expansion and contraction of concrete there is the end of concrete is too close. but when the length of the concrete member has exceeded a certain limit there is no endpoint where this volume change
there are two types of joints in concrete slabs, expansion joints and crack control joints. every concrete slab inside (basements, garages, warehouses) or outside (driveways, patios, entries, walkways, pool decks) are required to have joints every eight feet horizontally and vertically. this blog will try to answer the many questions that people have about driveway expansion joints.
for monolithic concrete, a good construction joint provides a well-bonded watertight surface, which allows for flexural and shear continuity through the joint. without this continuity, a weakened region results, which may serve as a contraction or expansion joint. a contraction joint is
expansion joints absorbing expansions and the contractions inherent to concrete buildings. designed to fill the gaps left between expansion joints in concrete slabs, expandacork products absorb the vibrations, expansions and contractions caused by thermal variations in different construction systems.
primer – sika® primer-3 n. joint backer rod – 15mm diameter sika® closed-cell polyethylene. the concrete primer will ensure that the sealant will bond properly to the concrete and the foam backing rod will reduce the amount of sealant needed. the primer-3 n come in 1 litre bottles – you should be able to prime around 40m of joints per
what is an expansion joint in concrete. all materials expand or contract with the increase or decrease in temperatures including concrete. therefore suitable arrangements are not ensured for the expansion and contraction of concrete due to the temperature changes the cracks may occur.
all types of waterstops to prevent liquid leaking. waterstop plays an important role in waterproofing a concrete structure, especially joints, the weakest part which is liable to leakage of water or chemical liquids. so waterstops are designed as a fluid-tight diaphragm embedded in or running along the joints to solve these problems.
used anywhere a separation or control joint is required. finished to the top of grade, zip off the top strip and finish. voidcap. a polystyrene cap with a removable top. when placed over asphalt impregnated expansion joint, the top section can be separated from the bottom section creating a 1/2″ x 1/2″ void on the surface of the concrete.
polyurea joint fillers with a shore a measurement of 80 may have a tensile elongation of 400%. however, they can expand only about 5% to 15% laterally before splitting or losing adhesion along the concrete bond line. epoxy joint fillers with an 80 shore a measurement with 25% elongation will usually tolerate 5% to 8% lateral expansion.
